An automated vulnerability scan provides an initial overview of the security posture of publicly accessible systems — such as web servers, web applications, or server infrastructure. Tools like Nmap, Burp, Tenable Nessus, and OpenVAS are used for this purpose.
A vulnerability scan at ZERBEROS is typically an integral part of a comprehensive external or internal penetration test. However, we can also conduct the scan as a standalone, recurring service — for example, as a monthly security check or as preparation for a larger audit.
More than an automated scan
The crucial difference lies not in the scan or the software itself, but in the expert analysis of the results. Automated tools often produce hundreds of entries — but not every finding is critical or even relevant.
Drawing on years of experience in penetration testing and real-world attack simulations, we contextualize, evaluate, and prioritize the results. Instead of a flood of raw data, you receive concrete, actionable recommendations — focused on actual risks.
Use cases
A vulnerability scan can…
- serve as the foundation for a subsequent penetration test,
- be repeated on a regular basis after a full security assessment,
- contribute to the early detection of system changes or emerging risks,
- analyze specific systems or network segments in a targeted manner,
- be deployed as a preventive measure in security-critical industries.
Why scan regularly?
Systems change. New software, configuration changes, or unpatched vulnerabilities can introduce new risks — often without anyone noticing. Regular scans allow you to respond to security-relevant changes early, before they turn into real threats.
Consequences of undetected vulnerabilities
Vulnerabilities that remain undetected and unresolved can lead to…
- system outages,
- revenue loss,
- data loss,
- reputational damage,
- and costs for emergency response and forensic investigation.
Particularly critical: the loss of customer data — for example through a compromised web shop — can permanently erode trust and drive customers to competitors.
Every system is a potential target
Automated attack tools systematically scan the internet for vulnerable systems — regardless of who owns them. Even seemingly insignificant systems can serve as an entry point or stepping stone for further attacks.
The assumption “our data is not interesting” offers no protection.
Security starts with visibility
Partner and extranet security
Organizations connected to partners, resellers, or service providers via extranets must secure not only their own environment but also the interfaces to external networks. A vulnerability scan helps make these transition points transparent and identify risks before they can be exploited.
Focused assessments available
Upon request, we can also perform targeted assessments of specific areas — such as a particular application, a server segment, or an extranet connection.
