According to recent reporting, over 183 million email-password combinations, including many tied to Gmail accounts, have surfaced online — gathered not from a direct breach of Google’s servers, but from malware-based harvesting and infostealer activity. 

This incident shows that no one is truly immune — even users of major services like Gmail must remain vigilant.

What We Know So Far

  • The leak involves approximately 183 million unique email/password pairs.
  • The data appears to stem from “infostealer” malware logs — i.e., malicious software installed on devices that captured credentials and uploaded them, rather than a single platform being hacked.
  • A large volume of the data reportedly includes Gmail accounts or credentials linked to Gmail users.
  • The credentials were often stored in plaintext (or easily reversable form) alongside other identifying data.
  • Importantly: this is not the same as saying Gmail itself was breached; rather, the leak is from external malware-based collection.

Why This Leak Represents a Real Threat

1. Password reuse across services

If your email + password were exposed, and you reuse the same credentials across banking, shopping, social media, cloud storage, then attackers may use them to gain access elsewhere.

2. Enhanced phishing & targeted attacks

Attackers armed with your email address (confirmed leaked) can craft more convincing phishing messages or credential-stuffing attempts, increasing the chance of success.

3. Automation and scale

With millions of credential pairs available, criminals can automate large-scale credential stuffing — trying leaked email/password combos across many services and platforms.

4. Hidden compromise & secondary risk

Even if the service you used wasn’t directly targeted, the fact that the credentials leaked means your digital identity has a serious vulnerability — which can lead to account takeover or fraud.

5. Time is of the essence

Every hour your compromised credentials remain unchanged increases the likelihood of misuse. Quick detection and reaction are essential.

 

How dfndr security’s Leaked Credentials Feature Protects You

If you use the dfndr security app, here’s how the built-in “Leaked Credentials” function becomes a key layer of defense:

    • It checks your email (and optionally other login data) against known databases of leaked credentials.
    • If your credentials are found, you receive an alert, enabling you to take immediate corrective action (change password, review account).
    • The app also supports best-practice recommendations: creating strong unique passwords, activating two-factor authentication (2FA), avoiding reuse of passwords.
    • In short, while the leak put credentials into circulation, dfndr acts as an early-warning system — helping you detect exposure and respond before attackers exploit it.
  • Without such a function, you might remain unaware of compromised credentials for a long time — giving attackers a head-start.

What You Should Do Right Now

    1. Change your password immediately on all accounts tied to the affected email(s). Use a strong, unique password for each service.
    2. Enable two-factor authentication (2FA) everywhere possible. This adds a vital extra layer of security.
    3. Use the dfndr security “Leaked Credentials” feature: check whether your email appears in the leak, and follow the app’s recommendations if it does.
    4. Avoid using the same password across multiple services. Consider a trusted password manager to generate/store unique passwords safely.
    5. Monitor your email inbox for suspicious activity: login alerts, unfamiliar password reset requests, etc.
    6. Scan your devices for malware or suspicious apps — since the leak was rooted in device‐based credential harvesting, device hygiene matters.
  • Educate friends/family: many people reuse weak passwords or aren’t aware of credential leaks — their vulnerabilities may impact you (via shared accounts, contacts, etc).

With over 183 million credentials already exposed, this is not just a theoretical risk — the data is floating around in cyber-criminal ecosystems.

Delaying action means increasing your exposure. Don’t rely on a service provider to alert you — many do not offer proactive notifications in time.

Being proactive now gives you a better chance at staying ahead of attackers.

This leak is a wake-up call: digital account security is no longer optional. But the good news: you can act now to defend yourself. With dfndr security’s Leaked Credentials feature, you can check your exposure, respond quickly, and reduce your risk of falling victim to attacks.

Open or download the dfndr security app, activate the Leaked Credentials check, and verify your accounts now. A few minutes of action can mean the difference between staying safe or becoming a victim.

Protect your digital world — start with dfndr security.

<![CDATA[Deepfakes: The New Weapon of Digital Scammers]]> https://www.psafe.com/en/blog/deepfakes-the-new-weapon-of-digital-scammers/ Mon, 27 Oct 2025 17:56:20 +0000 https://www.psafe.com/en/blog/?p=21387 The revolution of artificial intelligence has brought countless benefits to our daily lives — from virtual assistants to tools that optimize work and increase productivity. But along with these innovations, new risks have also emerged. One of the most dangerous and rapidly growing threats is the deepfake, a technique that uses AI to create fake videos, audio, and images that look incredibly real.

These fabrications can mimic faces, voices, and human expressions so convincingly that even experts often struggle to tell what is real and what has been digitally altered.

 

What Are Deepfakes?

The term deepfake combines deep learning (a type of advanced AI learning) with fake. This technology uses machine learning algorithms to analyze thousands of images and audio samples of a real person, learning their facial features, voice tone, and expressions. With this data, it becomes possible to create fake digital content — for instance, a video of someone saying something they never actually said.

At first, deepfakes were seen as a technological curiosity. But they quickly began to be used to spread misinformation, defame public figures, and carry out sophisticated scams.

 

How Criminals Are Using Deepfakes Today

The most common cases involve financial fraud and trust manipulation. Here are some real and potential scenarios:

The cloned voice scam: a seemingly legitimate audio message from a relative or boss asking for an urgent bank transfer. The voice, tone, and even pauses sound identical to the real person — but everything was generated by AI.

Fake videos on social media: celebrities or public figures shown in controversial situations or promoting fake products. These fabrications are used to attract clicks, spread fake news, or even manipulate elections.

Corporate fraud: deepfakes have been used to impersonate executives in virtual meetings, deceiving employees and resulting in million-dollar losses.

Romance scams: criminals use fake photos and videos in dating apps to emotionally and financially manipulate victims.

These practices are growing quickly — and becoming increasingly accessible. Today, anyone with a smartphone and an internet connection can create a basic deepfake in minutes, without being a programmer.

The Impact of Deepfakes on Society

The impact of this technology goes far beyond financial scams. It undermines trust in information, one of the pillars of the digital world.

As deepfakes become more realistic, it’s harder to believe what we see and hear online. This opens the door to disinformation campaigns, public defamation, and even personal blackmail with fake content.

Governments and tech companies worldwide are working to address this problem through legislation, authenticity tracking, and new security tools. Still, the line between real and fake is becoming increasingly blurred.

<![CDATA[How to identify a spy app on your smartphone]]> https://www.psafe.com/en/blog/how-to-identify-a-spy-app-on-your-smartphone/ Thu, 04 Sep 2025 10:33:39 +0000 https://www.psafe.com/en/blog/?p=21380 In the United States, the use of spyware apps is a growing concern, affecting mobile phone users. These hidden applications can compromise your privacy and security, but there are tangible signs and steps to help you detect and remove them.

Apps you don’t recognize

Review the complete list of apps installed on your phone. If you spot applications you don’t remember downloading or that seem suspicious, this is a red flag. Many spyware apps disguise themselves with innocuous names or hide within folders. To view the list of installed apps, you can use the scan feature in dfndr security.

Battery draining fast

Spyware runs silently in the background, consuming resources. If your battery suddenly drains much faster than usual—even without heavy usage—it could indicate hidden surveillance software.

Device overheating

Unusual overheating, especially while your phone is idle or performing basic functions, may be a sign that malicious apps are running behind the scenes.

System slowdowns and freezes

If your phone becomes sluggish, apps crash, or the operating system feels buggy, spyware could be stealing system resources for its activities.

Unusual data usage

Watch for unexplained spikes in your monthly data usage. Spy apps often transmit information back to the attacker using your cellular data, so increased usage with no clear cause deserves attention.

Messages marked as read

If your texts or messages appear as read before you’ve opened them, this could mean someone—or something—is accessing them without your consent.

Strange sounds during calls

Persistent echoes, static, or faint voices during phone calls might signal that spyware is listening in or recording your conversations.

Unfamiliar files or settings

Find files, photos, or changed settings you didn’t create or modify? These artifacts can be leftover evidence of spying apps.

How to protect yourself

  • Always inspect app permissions and review what access each app has to your device (camera, microphone, location).

  • Run a full scan with a trusted antivirus, such as dfndr security, which detects and removes hidden spy apps and threats automatically.

  • Keep your operating system and all apps updated to defend against newly discovered vulnerabilities.

  • Use strong, unique passwords and enable two-factor authentication whenever possible.

Proactive Tools

Modern apps like dfndr security have features to display all installed apps, monitor for privacy risks, provide real-time protection against malware, and alert users about leaked data or unauthorized access. Using such solutions along with general awareness greatly reduces your risk.

Your best defense is vigilance: question unfamiliar apps, strange device behavior, and always be mindful of your digital footprint. Stay protected by keeping your phone secure and up to date.

<![CDATA[5 trending digital scams: how AI is making fraud more dangerous]]> https://www.psafe.com/en/blog/5-trending-digital-scams-how-ai-is-making-fraud-more-dangerous/ Thu, 28 Aug 2025 10:18:41 +0000 https://www.psafe.com/en/blog/?p=21376 Every day, millions of mobile phone users receive malicious links through SMS, email, or social media. These links are increasingly sophisticated: with the assistance of artificial intelligence, scammers can craft messages without errors and even personalize them to their victims.

Phishing and Smishing With AI

AI-powered scams use personalized messages to deceive even cautious users. Scammers pose as trustworthy companies, requesting sensitive data, passwords, or money transfers. Reports show an increase in phishing driven by AI-generated emails to improve speed and credibility.

Payments Scams

Fraudsters deploy malicious apps that monitor and divert transactions, fake QR codes to mislead payment, and false requests for refunds. Techniques even include impersonating tax authorities or banks, demanding quick responses to fraudulent claims.

Fake Call Centers and Employees

Scammers simulate bank call centers, aiming to capture passwords, install malware, or transfer funds. The rise of synthetic AI voices allows for more convincing vishing attacks, making phone-based fraud much harder to detect and resist.

Fake E-Commerce

False online stores and social media profiles lure victims with unreal deals; after payment (often via instant transfer platforms), no product is delivered. AI tools help scammers design authentic-looking websites and manage deceptive customer interactions.

SIM Swap

Criminals transfer a victim’s phone number to a new chip, gaining access to bank accounts and social media via SMS codes. SIM swap fraud has spiked over 1,000% year-on-year, fueled by AI-powered social engineering and voice cloning. Attackers exploit weak carrier identity checks and automated support systems, quickly hijacking entire digital identities and financial assets.

General Recommendations

  • Never click links from unknown sources.

  • Always use two-factor authentication.

  • Be skeptical of offers that seem too good to be true.
  • Keep your phone and apps up to date.

  • Use trusted mobile antivirus software. 

If you want maximum protection for your device, consider downloading security apps such as dfndr security for real-time defense.

<![CDATA[Malicious links: what they are and how to protect yourself]]> https://www.psafe.com/en/blog/malicious-links-what-they-are-and-how-to-protect-yourself/ Wed, 13 Aug 2025 15:44:31 +0000 https://www.psafe.com/en/blog/?p=21365 Every day, millions of  cell phone users receive malicious links via SMS, email, or social media. These scams are growing more sophisticated—scammers now commonly use artificial intelligence to create error-free and even personally tailored messages.

Common tactics used by scammers

  • Shortened or masked links: Attackers use shortened URLs or complex domain names to obscure the true destination, making it difficult to spot a dangerous link before clicking.

  • Deceptive promises and urgency: Phishing messages often promise sweepstakes winnings, flash sales, package deliveries, or urgent bank notifications to lure users into clicking quickly without thinking.

  • Fake websites and data entry forms: Clicking a malicious link may redirect you to a convincing fake website where you’re asked to input sensitive details—like banking data, Social Security numbers, or passwords—or may silently trigger a malware download.

  • Impersonation tactics: Scammers frequently impersonate trusted organizations—such as banks, government agencies (e.g., IRS), or online retailers—to legitimize their claims and increase the likelihood of success.

  • Social media exploits: On platforms like Facebook, Instagram, and LinkedIn, fake profiles or posts lure users with job offers, urgent security warnings, or giveaway announcements, often prompting users to click malicious links or divulge private information.

Real-world impact

<![CDATA[Zero Trust: what it is, why it matters, and how dfndr security protects your phone with this concept]]> https://www.psafe.com/en/blog/zero-trust-what-it-is-why-it-matters-and-how-dfndr-security-protects-your-phone-with-this-concept/ Thu, 03 Jul 2025 18:17:58 +0000 https://www.psafe.com/en/blog/?p=21359 Have you heard of Zero Trust? The term is one of the most  important trends in cybersecurity today—and is increasingly present in mobile device protection. Explore the concept, understand its importance, and see how dfndr security puts Zero Trust into action to protect both you and your smartphone.

What is Zero Trust?

Zero Trust is a cybersecurity model based on the principle that no network, user, or device should be trusted by default, even if it is “inside” the protected environment. In other words, every access attempt must be verified and authenticated, regardless of its origin. The concept emerged to address the rise in digital threats, user mobility, and the popularity of remote work and cloud computing, which have eliminated traditional security boundaries.

In the Zero Trust model, the rule is clear: never trust, always verify. This means every connection, access, and action is continuously monitored and validated, drastically reducing the chances of attackers exploiting vulnerabilities or moving freely within a system.

Why is Zero Trust important?

With the growth of digital threats and the digitization of personal and professional life, relying solely on traditional security barriers (such as firewalls or standalone antivirus) is no longer enough. Zero Trust offers key benefits:

  • Holistic protection: Covers users, devices, applications, and data, reducing security gaps. 
  • Risk mitigation: Prevents threats from spreading laterally in case of a breach; each access is isolated and monitored. 
  • Fast detection and response: Greater visibility into activities, making it easier to identify and respond to suspicious behavior. 
  • Sensitive data protection: Ensures only authorized users and devices have access to confidential information. 
  • Adaptation to mobile and remote environments: Essential for scenarios where access occurs from any location and device. 

How dfndr security applies Zero Trust to protect your phone

dfndr security incorporates the main pillars of Zero Trust to protect your smartphone from digital threats, scams, and data leaks. Here’s how:

  • Continuous monitoring and constant verification: the app performs automatic and real-time scans, detecting and removing viruses, malware, spyware, and other threats as soon as they appear. No app, file, or link is considered safe without a rigorous analysis. 
  • Protection against scams and phishing attempts: dfndr security identifies and blocks malicious links, fake websites, and phishing scams—even if the threat comes from known contacts or trusted networks. Anti-phishing is a highlighted feature in the English blog, with the app using machine learning and AI to detect phishing in SMS, WhatsApp, and Facebook Messenger, among others (see https://www.psafe.com/en/blog/new-cyber-threats-targeting-android-phones/ ). 
  • Identity and credential monitoring: The 24/7 credential monitoring feature alerts you immediately if your email, password, or personal data leaks online, allowing quick action to prevent harm.  
  • App access control: Allows you to lock access to sensitive apps with a password, preventing curious people or attackers from accessing your personal information even if they have your device. 
  • Alerts against WhatsApp cloning and fraud: dfndr security monitors for cloning attempts and scams on WhatsApp, sending real-time alerts and reinforcing protection against fraud that exploits user trust. 
  • Safe app installation: Before installing any app, dfndr security checks if it’s safe, preventing malicious apps from accessing your device. 

Zero Trust in the palm of your hand

dfndr security translates the Zero Trust concept to the mobile universe, applying the logic of “never trust, always verify” to every action, access, and connection on your phone. Thus, even in a scenario of growing threats—including those driven by artificial intelligence—your device remains protected and you stay in control of your digital security.

<![CDATA[5 Reasons to Use Biometrics to Secure Mobile Devices]]> https://www.psafe.com/en/blog/5-reasons-to-use-biometrics-to-secure-mobile-devices/ Thu, 22 May 2025 18:53:36 +0000 https://www.psafe.com/en/blog/?p=21349 Mobile devices have become essential tools in both our personal and professional lives, but they are increasingly targeted by cybercriminals.

As threats like phishing and data breaches rise, organizations and individuals are seeking more robust ways to protect sensitive information.

Biometric authentication—using unique biological characteristics such as fingerprints, facial recognition, or voice patterns—has emerged as a leading solution. Here are five compelling reasons to use biometrics to secure your mobile devices:

  1. Eliminates the Threat of Passwords

Passwords remain one of the weakest links in mobile security. Over 80% of company data breaches are attributed to weak or stolen passwords. Many users still rely on simple, easily guessed passwords or reuse the same password across multiple accounts, making it easier for hackers to gain unauthorized access. Biometrics remove this vulnerability by replacing passwords with something unique to each user, significantly reducing the risk of data breaches.

Read more: How many different passwords should you have?

  1. More Convenient for Users

Remembering and resetting passwords can be frustrating and time-consuming. Biometric authentication streamlines the process—users can unlock their devices or access sensitive apps with a simple fingerprint scan or facial recognition. This not only saves time but also enhances the user experience, as you can’t forget your fingerprint or face.

  1. Greater Accountability

Biometrics provide a clear audit trail of who accessed a device or network and when. Unlike passwords, which can be shared or stolen, biometric data is unique to each individual. This accountability is crucial for organizations that need to track access and investigate potential security incidents.

  1. Widespread Adoption and Trust

Biometric technology is rapidly becoming the standard for mobile security. Over 60% of employers already use biometrics in the workplace, and nearly half use it specifically to secure mobile devices. As more consumers and businesses adopt this technology, its effectiveness and reliability continue to improve.

  1. High Return on Investment (ROI)

Implementing biometric security can lead to significant cost savings. By reducing the risk of costly data breaches and minimizing the need for password resets and IT support, organizations can achieve a high ROI. For example, one bank reported a 191% ROI after adopting biometric authentication.

Therefore, we use biometrics in the dfndr security applock.

<![CDATA[Vulnerabilities in Cyber Security: what they are and how to fix them?]]> https://www.psafe.com/en/blog/vulnerabilities-in-cyber-security-what-they-are-and-how-to-fix-them/ Wed, 18 Jan 2023 15:08:39 +0000 https://www.psafe.com/en/blog/?p=21305 According to the 2022 Verizon Data Breach Investigations Report, vulnerability exploitation is one of the most common tactics used by hackers to cause a data breach. That means even simple vulnerabilities can have serious consequences, from loss of customer trust to millions of dollars in damages. Recently, big companies such as Twitter and Deezer suffered data breaches. 

In this post, you will learn everything about vulnerabilities in cybersecurity. Including what the most common are, how you can close this unwanted open door without spending too much money, and more. 

Let’s get to it. 

What is a vulnerability in cybersecurity? 

A vulnerability in cybersecurity is like a weakness or a hole in a wall that protects your computer or online information. Cybercriminals can use these exploits to access personal information, steal sensitive company data, take control of a device, or launch massive attacks, such as ransomware. 

An example of a vulnerability is a misconfiguration on a system that someone with malicious intent can exploit for personal gain.

For example, imagine you have a lock on your front door to keep your house safe. But, if someone made a mistake installing the lock or the key is easy to copy, it becomes a vulnerability that a thief can exploit to break into your house. Now imagine you are not aware of these problems. That means that someone that knows can come and go into your home as they please, and you would never have a clue.

In the same way, if a website or software has a vulnerability, a hacker can use it to gain access to sensitive information or take control of the system. Likewise, you would have no clue what is happening, until it’s too late.

Almost all technology has some vulnerability, from smartphones your employees use, to the software that runs your network. Cybercriminals are always finding new vulnerabilities, so it is crucial to stay vigilant and act quickly to protect your information, staying one step ahead of hackers before they can break into your home.

Why are companies’ websites vulnerable? 

Company websites can be vulnerable to cyber attacks for a variety of reasons. Some examples are: 

  1. Outdated software: Websites that are not regularly updated may be using outdated software that has known vulnerabilities that can be exploited by hackers.
  2. Compromised passwords: Some websites may have weak or easily guessable passwords, making it easy for hackers to gain access. In other cases, the passwords are not stored correctly, being exposed by hackers to find them. And to top it off, data breaches might contain passwords that can still be used to log into a service. 
  3. Lack of security measures: Some companies may not have adequate security measures in place to protect their websites from cyber attacks.
  4. Third-party vulnerabilities: This is a big one, that even big companies are vulnerable to. Websites that use third-party plug-ins or other software may be vulnerable if those third-party providers have security vulnerabilities.

It all comes down to this: hackers are betting that most companies will not have the time, or the money, to keep up-to-date on their cybersecurity. After all, expert professionals can be quite expensive.

How do hackers exchange information about vulnerabilities?

To make matters worse, not only these vulnerabilities exist, but hackers exchange information about them and even sell this information to other hacker groups. This level of organization and information sharing is unprecedented, highlighting the danger even more. Here are a few methods that hackers use to share intel: 

  1. Online forums: Hackers may use online forums and message boards to share information about vulnerabilities and exploit code.
  2. Dark web and Deep web: Hackers may use the dark web and deep web to share information about vulnerabilities, exploit code, and other hacking tools.
  3. Social media: Hackers may use social media platforms to share information about vulnerabilities and exploit code.
  4. Private channels: Hackers may also use private channels, such as encrypted messaging apps, to share information about vulnerabilities with other hackers, making it almost impossible to track.
  5. Vulnerability markets: Some hackers may sell information about vulnerabilities to other hackers or to organizations that will pay for the information.

That means that when one vulnerability is discovered, almost instantly, every hacker in the world can have access to that information, conducting attacks on their own. That makes it sound almost impossible to stay on top of these vulnerabilities, right? Not really. 

Fortunately, there are ways to fight them, with minimal effort, and without breaking the bank. 

Let’s get to them. 

What is the CVE? 

The Common Vulnerabilities and Exposures (CVE) is a system for identifying and cataloging known security vulnerabilities in software and other systems. The goal of the CVE is to provide a standard way to describe and identify these vulnerabilities so that they can be easily tracked and managed.

A CVE entry will typically include a description of the vulnerability, the affected software or system, and any known exploit code or attack methods. The entry may also include information on the impact of the vulnerability, such as the potential for data loss or unauthorized access, and the severity of the vulnerability, such as whether it can be used to take control of a system.

The CVE system is maintained by the MITRE Corporation, a non-profit organization, and is sponsored by the US government. The CVE is a widely used system and it is important for software vendors, security researchers, and other stakeholders to use the system to ensure that vulnerabilities are accurately and consistently identified.

When a software vendor or researcher identifies a new vulnerability, they will typically submit a request to MITRE to create a new CVE entry for that vulnerability. This allows other organizations to easily track and manage the vulnerability, and to take appropriate action to protect their systems and data.

To summarize, the CVE acts to counterbalance the hacker information trade machine. While they trade and gather information for attacks, the CVE (and other methods) provide information for defensive purposes. 

10 common vulnerabilities on websites

The CVE has cataloged over 200.000 known vulnerabilities. That is an astounding number, but with the help of an automated tool and a little prioritization, a company can manage without spening much and without a deticated team of cybersecurity experts. 

To get a little more practical, we have a few examples of common vulnerabilities, and what they mean: 

Injection attacks

Injection attacks occur when an attacker can insert malicious code into a web application, allowing them to access or modify sensitive data. This can include SQL injection, where an attacker inserts malicious SQL code into a web application, and command injection, where an attacker inserts malicious commands into a web application.

Cross-site scripting (XSS)

XSS attacks occur when an attacker can inject malicious code into a web page viewed by other users. This allows the attacker to steal user data, such as cookies and session tokens, and perform other malicious actions.

Broken authentication and session management

This occurs when an attacker can gain unauthorized access to a user’s account by exploiting weaknesses in the authentication and session management systems of a web application.

Insecure direct object references

This occurs when a web application references an internal object, such as a file or database record, using user-supplied input without proper validation. This can allow an attacker to access or modify sensitive data.

Vulnerabilities in security misconfiguration

This occurs when a web application or the underlying server is not configured securely, leaving it vulnerable to attack. This can include issues such as leaving default accounts and passwords in place, and not properly securing configuration files.

Vulnerabilities in Sensitive data exposure

This occurs when a web application does not properly protect sensitive data, such as credit card numbers and personal information. This can include issues such as storing data in plain text or using weak encryption.

Cross-site request forgery (CSRF)

This occurs when an attacker can trick a user into using a web application without their knowledge or consent. This can include actions such as changing a password or making a purchase.

Using components with known vulnerabilities

This occurs when a web application uses components, such as libraries and frameworks, that have known vulnerabilities. This can include issues such as using an outdated version of a library with known security issues.

Unvalidated inputs

This occurs when a web application does not properly validate user-supplied input, allowing an attacker to inject malicious code or perform other malicious actions.

Failure to restrict URL access

This occurs when a web application does not properly restrict access to sensitive URLs or pages, allowing an attacker to gain unauthorized access to sensitive data or perform other malicious actions.

How can a business find and manage vulnerabilities? 

Even with every tool at their disposal, businesses still have a hard time maintaining their online perimeter secure. That is perfectly understandable, considering how many digital tools a company uses, especially since each one of them might contain multiple exploits. The great news is that it’s possible to know all vulnerabilities without spending much and without a big dedicated cybersecurity team. 

For instance, a small business can find and manage vulnerabilities on its website by using a vulnerability scanner, which is a software tool that automatically checks for known vulnerabilities in web applications and their underlying systems. These scanners can check for a wide range of issues, including SQL injection, cross-site scripting, and insecure file permissions.

Once you have identified all vulnerabilities, the next step is to prioritize them based on their potential impact and ease of exploitation. The business can then develop and implement a plan to address the vulnerabilities, which may include patching or upgrading software, modifying configurations, or implementing additional security controls. 

Overall, regular monitoring and maintenance are key to managing vulnerabilities on a website.

Conclusion

In conclusion, identifying and managing vulnerabilities on a website is an essential part of maintaining the online security of your business. By using vulnerability scanners, prioritizing vulnerabilities based on potential impact, and implementing a plan to address them, you can help protect your website and your business from potential attacks, without spending too much money or overworking your IT team. You also don’t need a big team of cybersecurity experts to keep your company safe. 

It is also important to remember that website security is an ongoing process. Regular monitoring and maintenance are crucial to ensure the business has total visibility on any new vulnerability and that you have dealt with all previously known exploits. With the right tools and approach, you can help keep your website and business safe with less effort than you can imagine.
