Critical Severity Findings

These are the red flags. Think remote code execution, active exploit kits, or unpatched zero-days. If left unresolved, they could be used to fully compromise systems, exfiltrate data, or pivot deeper into your environment.

Often tied to weak encryption, public admin interfaces, or outdated services. These vulnerabilities are highly attractive to attackers because they require minimal effort and offer maximum impact if chained or misused.

Medium Level Weaknesses

These may not open the front door, but they sure rattle the locks. Think missing security headers, outdated software versions, or minor misconfigurations that—if combined—could open a path for escalation.

Pass or Fail

ASV scans don't leave room for interpretation. You either meet the PCI bar or fall short. One critical vulnerability, one mis-scoped IP, one unsigned attestation—and your scan fails. It's binary. And for compliance, that binary matters.

All Services Properly Identified and Scanned
Attestation Form Accurately Completed and Submitted

Common Findings

These repeat offenders show up in almost every ASV scan—often overlooked, always risky.

Expired Certificates

SSL certificates not renewed in time weaken encrypted session trust instantly.

Weak Ciphers

Deprecated encryption algorithms still accepted—easily broken with modern tools.

Outdated Services

Legacy software versions expose known vulnerabilities and are rarely patched properly.

Open Ports

Unnecessary ports left exposed create easy entry points for attackers.

Self-Signed Certs

These break chain-of-trust validation, triggering browser warnings and scan failures.

Insecure Protocols

Protocols like SSLv2/3 or TLS 1.0 no longer meet compliance standards.
