Vulnerability scanners rely on databases of known weaknesses, like antivirus software, but with the increasing number of vulnerabilities (nearly 30,000 a year), no single scanning engine can stay updated. Even top scanners like Tenable's Nessus and OpenVAS have coverage gaps and biases towards certain software types. This raises questions about whether one scanner is sufficient
Integrating multiple scanners, like what Intruder offers with Nuclei, enhances coverage and understanding of an organization's attack surface. Nuclei, an open-source scanning engine, provides quick and extensive checks for weaknesses, complementing existing scanners. Intruder's multi-scanner approach helps detect more vulnerabilities, such as exposed login panels, improving attack surface security by revealing risks missed by a single scanner. By continuously monitoring changes with an automated tool like Intruder, organizations can reduce their exposure to opportunistic attackers and prioritize addressing the most critical vulnerabilities effectively. ```https://thehackernews.com/2024/05/when-is-one-vulnerability-scanner-not.html
