What Is an ASV Scan | Approved Scanning Vendor

What Is an ASV Scan?

External scan by PCI-certified vendor to detect vulnerabilities on internet-facing systems.

Only authorized scanning vendors can perform these standardized, high-assurance vulnerability scans effectively.

Focuses exclusively on systems exposed to the internet—web servers, mail gateways, and firewalls.

Follows strict methodologies to minimize false positives and maintain consistent results across environments.

Detects exploitable flaws like outdated software, weak configurations, and exposed services before they're weaponized.

Routine scheduling ensures vulnerabilities don't quietly accumulate between infrequent security reviews.

Delivers an easy-to-interpret verdict that helps prioritize urgent fixes without technical confusion.

External vulnerability scans required by PCI DSS, performed by trusted, approved scanning vendors for internet-facing systems.

Each ASV scan produces a clear pass/fail outcome—no guesswork, just a decisive compliance verdict.

Failed scans include detailed vulnerability data, helping teams quickly prioritize and fix compliance-blocking flaws.

Pass results are used as official documentation during PCI audits and client due diligence reviews.

Any failed scan demands remediation followed by a new scan to achieve compliance status. No shortcuts.
