Check if your systems are vulnerable to the most critical, actively-exploited CVEs. Each scanner cross-references NIST NVD data. Free, minutes, no signup.
Run a full vulnerability scan — we check for all 200+ CVEs simultaneously and show you which ones apply to your stack.
Run Full Vulnerability Scan — Free →CVE (Common Vulnerabilities and Exposures) is a list of publicly disclosed security vulnerabilities maintained by MITRE Corporation and funded by the U.S. Department of Homeland Security. Each CVE entry contains a unique identifier, description, and references to patches or advisories.
NIST's National Vulnerability Database (NVD) enriches each CVE with CVSS scores, weakness classifications (CWE), and configuration data (CPE). A CVSS score of 9.0+ indicates a Critical vulnerability that typically allows unauthenticated remote code execution.
VulnScan's CVE scanners are built specifically for external attack surface scanning — checking for CVE exposure from an attacker's perspective, without requiring internal network access or agent installation.
We perform passive, external fingerprinting of your server's technology stack, version numbers, and behavior — then cross-reference against the NIST NVD database. If your exposed software matches a vulnerable version, we flag it with the corresponding CVE.
Yes. VulnScan performs non-intrusive passive scanning only. We never attempt to exploit vulnerabilities or modify your systems. Our scanning is equivalent to what benign crawlers like Shodan and security researchers do every day.
NIST publishes dozens of new CVEs daily. VulnScan focuses specifically on CVEs with public exploit code or confirmed in-the-wild exploitation — the ones attackers are actually using right now.
