What Are the Uses for a Vulnerability Scanner?
Cyberattacks have become so common that you can expect to see news about a breach every week. Just recently, Twitter experienced a breach that affected high-profile US Twitter accounts. This attack highlights the need for proactive security measures, such as vulnerability scans.
Today’s hyper-connected world calls for extreme vigilance and knowledge of the ever-present threat of cyberattacks. These cyberattacks typically exploit vulnerabilities to breach your networks. What better way to prevent these attacks than to conduct regular vulnerability scans?
What Is a Vulnerability Scanner?
Your network is constantly exposed to threats, and loopholes that could result in catastrophic incidents for your business were threat actors to identify them. Vulnerability scanners simply help identify these threats early enough before threat actors can find them. You can rely on them to scan your system or network for vulnerabilities while comparing the results to pre-established vulnerability databases. Some common vulnerability scanners include ImmuniWeb, Tripwire IP360, Paessler PRTG, and Acunetix.
How to Effectively Use Vulnerability Scanners
For you to effectively use vulnerability scanners, you need to scan your system and network often. The databases that contain recently discovered vulnerabilities tend to be updated often. Ideally, having a team in charge of these scans is ideal.
Once you are done with a scan, the team will assess the ad hoc reports. If they identify an issue with your system, they will suggest a remedy for mitigating the risks involved. Most databases tend to suggest solutions for the vulnerabilities they expose.
Types of Vulnerability Scans
Cyberattackers target flaws or vulnerabilities in networks, systems, and web applications with the sole purpose of exploiting them. For example, when dealing with application vulnerability management, the developers will seek to identify vulnerabilities, such as SQL injection, cross-site scripting, security misconfiguration, failure to restrict URL access, and LDAP injection.
To identify such vulnerabilities, organizations employ different vulnerability scans based on their testing objectives. The most common vulnerability scans include:
- External Vulnerability Scans
External scans aim to identify threats that can arise from outside our network, especially on the externally facing services. They are targeted at external IP addresses and ports.
For instance, they can help you assess new services and servers launched since the last time you conducted a scan and any threats associated with them. Some common threats you can find include having servers configured with deprecated services and unsecured transfer protocols. Ideally, you should perform these scans once each month to avoid over/underdoing them. A good example of these scanners is ImmuniWeb.
- Internal Vulnerability Scans
Cybersecurity threats can originate from anywhere, even from within your network. Don’t focus all of your resources on external threats and forget that disgruntled employees can target your network. You could also have missed a threat that seeped through your defences. This kind of threat could open up your network to attacks.
You need to perform an internal vulnerability scan to identify these threats. It also seeks to identify vulnerabilities such as encryption weaknesses, missing patches, and configuration weaknesses.
Keep in mind that internal scans are more complicated compared to external scans as they seek to assess your internal assets. These assets include everything in your network, such as vulnerable software. An internal scan will focus on your network’s internal components, searching for possible vulnerabilities and any other points of exploitation. A good example of such scanners is the Paessler PRTG.
- Environmental Vulnerability Scans
These scans are specific to certain IT environments, including mobile device-based environments, cloud-based environments, IoT devices, etc. Most of these environments are semi-isolated from the entire organization’s network, but they could wreak havoc to the rest of the network if a breach were to occur. Tripwire IP360 is a good example of such scanners.
For instance, IoT systems tend to be less secure than normal devices since most are designed with security as an afterthought. In turn, most manufacturers work overtime to identify security loopholes before sending out updates to patch these issues. A vulnerability scan will identify unpatched weaknesses in your IoT environment, which can be insightful in protecting your organization.
How Effective Is Vulnerability Scanning?
Vulnerability scanning is effective in identifying vulnerabilities in a network. In fact, 60 per cent of security breaches occur despite there being an existing patch for the ad hoc vulnerability. A scan generates a report of its findings, which you can use to patch the vulnerabilities. However, it’s more effective when combined with other cybersecurity measures, such as penetration testing and vulnerability assessment.
Vulnerability Scan vs. Penetration Test vs. Vulnerability Assessment
These three terms are often used interchangeably, but they don’t have similar meanings. For example, you might ask for a penetration test, but what you really need is a vulnerability assessment. To avoid this confusion, learn to differentiate the three.
What Is a Vulnerability Scan?
A vulnerability scan is run by automated software that tries to identify vulnerabilities in your network or system. It’s a simple process, as explained earlier. It merely identifies the vulnerabilities based on a database of vulnerabilities.
While these scans are important, you shouldn’t rely solely on them. This is because if you run a vulnerability scan and report indicates that your system has no vulnerabilities, it doesn’t necessarily mean that your system is fine. Vulnerability scans play an important role in improving an organization’s security, but they aren’t enough. You need a comprehensive cybersecurity strategy that includes vulnerability assessment and penetration testing.
What Is a Vulnerability Assessment?
A vulnerability scan will identify the weaknesses and flaws in your network, but it doesn’t explain the magnitude of these vulnerabilities. You’ll know your network has vulnerabilities, but you have no idea the extent of the damage that these vulnerabilities can inflict on your business.
To understand the damage that these vulnerabilities can cause, you need to conduct a vulnerability assessment, as it takes into account all the assets in your IT infrastructure.
The first stage of the vulnerability assessment is to match all the assets in your environment with their vulnerabilities. This will include your networks, hardware, software, web applications, etc.
Once you’ve matched assets with their vulnerabilities, you will start evaluating the effects the vulnerabilities can have on your business. This will typically require you to assess the impact a weakness can have and the probability of it occurring.
A vulnerability assessment is considered essential as it gives you an idea of what your system can handle, the threats it’s facing, and the magnitude of the threats.
What Is Penetration Testing?
The primary aim of vulnerability assessments and vulnerability scans is to identify vulnerabilities; in contrast, penetration testing seeks to exploit these vulnerabilities. Penetration tests are typically conducted by third parties several times a year as opposed to vulnerability scans, which are conducted more frequently.
Penetration testing begins by identifying weaknesses such as insecure business processes, vulnerable databases, etc. In the next phase, the penetration tester tries to exploit these vulnerabilities.
All three are important and should be part of your cybersecurity strategy. However, you should prioritize vulnerability assessments to keep up with ever-lurking cyberattackers. In contrast, penetration tests can be performed once or twice a year.
Wrapping It Up
Cyberattackers will always try to breach your security, and their primary target will be vulnerabilities that they can exploit. As long as you’re in a connected world, there is always a risk that your network will be hacked. Hackers will breach even the best defences as long as there is a weak link.
However, you can prevent these attacks by constantly scanning your IT infrastructure for vulnerabilities. Don’t stop there. Conduct a vulnerability assessment to help you identify these vulnerabilities, and rank them according to the degree of damage they can cause. Include penetration testing bi-annually or annually to test how your IT infrastructure would fare against an external attack.
Cyberattackers are constantly poking around your network looking for weaknesses, and if you don’t implement measures to strengthen your cybersecurity, they will eventually find these flaws and exploit them. You don’t need complex security measures; a simple vulnerability scan will act as a good starting point.

The parent company of Facebook, WhatsApp, and Instagram, Meta, has strengthened its teen safety online with an expansion of its AI-powered age assurance measures.
This is part of efforts to create safer, age-appropriate experiences for young people across its platforms. Through a combination of AI, product design, and parental support tools, Meta continues to strengthen how it identifies teens, protects them by default, and supports families in navigating digital environments.
Strengthening underage enforcement with advanced AI
Meta requires users to be at least 13 years old to use its platforms and continues to invest in advanced technologies to uphold this policy at scale. As part of these efforts, the company is further enhancing its AI-driven systems to more effectively identify and take action on accounts that may belong to underage users.
These advancements include:
Contextual AI analysis across profiles: Meta’s systems analyse a wide range of signals—including posts, comments, bios and captions—to identify contextual indicators such as references to school environments or age-related milestones. This capability is being expanded across additional surfaces within Meta’s apps, strengthening enforcement more consistently and proactively.
Advanced visual analysis technology: Meta is introducing AI that can interpret general age-related cues within photos and videos. This technology estimates age ranges based on broad characteristics and does not use facial recognition or identify individuals. When combined with behavioural and textual signals, it significantly enhances detection accuracy.
Expanded enforcement and verification processes: Accounts identified as potentially underage are subject to age verification requirements. Where age cannot be confirmed, accounts may be removed to maintain platform integrity.
Improved reporting and flagging tools: Meta is making it easier for people to report suspected underage accounts through simplified reporting flows available both in-app and via the Help Centre, helping surface potential violations more efficiently.
AI-supported review systems: To improve consistency and speed, Meta is supplementing human review teams with AI models that apply standardised evaluation criteria to reports, enabling faster and more reliable enforcement outcomes.
Stronger circumvention safeguards: Meta is also enhancing its ability to detect and prevent repeat attempts by users who may try to bypass age restrictions by creating new accounts.
While many of these AI-driven systems are already in use globally, certain advanced capabilities continue to be rolled out progressively across additional markets.
Expanding Teen Account protections
Meta continues to expand its Teen Account framework, which is designed to provide built-in protections that limit unwanted contact and reduce exposure to inappropriate content. Since its introduction, hundreds of millions of teens have been enrolled in these protections across Instagram, Facebook, and Messenger.
These protections include automatically placing teens under 18 into age-appropriate experiences, including a default 13+ content setting designed to limit exposure to sensitive content.
Building on this progress, Meta is further scaling its proactive detection technology that identifies users who may be teens—even if they have entered an adult birthdate—and automatically places them into age-appropriate settings. This technology, already rolled out in several markets, is being expanded to additional regions to make these protections available more broadly over time.
Supporting parents with tools and guidance
Meta continues to support parents as key partners in helping teens navigate online experiences safely. The company is introducing new notifications and guidance designed to help parents better understand how to verify their teen’s age and encourage open conversations about the importance of providing accurate information online.
These efforts build on existing resources available through Meta’s Family Centre, which provides tools and educational materials to help families manage their digital experiences more effectively.
Meta also maintains age verification requirements for users who attempt to change their age in ways that may bypass protections, using a combination of ID verification and facial age estimation tools.
Advocating for industry-wide solutions
Meta continues to emphasise that age assurance is a complex, industry-wide challenge that requires broader collaboration. The company supports approaches where age verification is conducted at the operating system or app store level, enabling developers to deliver consistent, age-appropriate experiences across apps.
In addition to AI-based detection, Meta uses age estimation based on user activity and signals, as well as user reports, to help determine whether someone may be misrepresenting their age.
