Vulnerability Scanning

Vulnerability scanning is the automated process of probing systems, networks, and applications to detect known security weaknesses. Scanners compare system configurations, software versions, and application behaviors against databases of known vulnerabilities (CVEs) and security misconfigurations. Scanning is typically the first step in a vulnerability management program.

Vulnerability scanners come in several categories: network scanners (Nessus, Qualys) that check hosts and services, web application scanners (DAST tools) that test running web apps, and authenticated scanners that log into systems for deeper inspection. While scanners provide broad coverage and consistency, they are limited to detecting known vulnerability patterns and frequently produce false positives. They cannot discover business logic flaws or chain vulnerabilities together.

How APVISO tests for this: APVISO goes far beyond traditional vulnerability scanning. While scanners check for known signatures, APVISO's AI agents reason about application behavior, test for logic flaws, and chain findings together — combining automated coverage with the depth of manual penetration testing.
