VDR-TFR-PVR Mitigation and Remediation Expectations

Class A

Providers with Class A Certifications SHOULD partially mitigate vulnerabilities, fully mitigate vulnerabilities, or remediate vulnerabilities to a lower potential agency impact within the timeframes from evaluation shown below, factoring for the current Potential Agency Impact N-rating as defined in VER-EVA-EPA (Estimate Potential Agency Impact), internet reachability, and likely exploitability.

Timeframes by impact level

Level	Internet-Reachable Vulnerability + Likely Exploitable Vulnerability	Not Internet-Reachable Vulnerability + Likely Exploitable Vulnerability	Not Likely Exploitable Vulnerability
1
2	96 days	160 days	192 days
3	32 days	64 days	192 days
4	8 days	32 days	64 days
5	4 days	8 days	32 days

Class B

Providers with Class B Certifications SHOULD partially mitigate vulnerabilities, fully mitigate vulnerabilities, or remediate vulnerabilities to a lower potential agency impact within the timeframes from evaluation shown below, factoring for the current Potential Agency Impact N-rating as defined in VER-EVA-EPA (Estimate Potential Agency Impact), internet reachability, and likely exploitability:

Timeframes by impact level

Level	Internet-Reachable Vulnerability + Likely Exploitable Vulnerability	Not Internet-Reachable Vulnerability + Likely Exploitable Vulnerability	Not Likely Exploitable Vulnerability

3	16 days	32 days	128 days
4	4 days	8 days	64 days
5	2 days	4 days	16 days

Class D

Providers with Class D Certifications SHOULD partially mitigate vulnerabilities, fully mitigate vulnerabilities, or remediate vulnerabilities to a lower Potential Agency Impact N-rating within the maximum timeframes from evaluation shown below, factoring for the current Potential Agency Impact N-rating as defined in VER-EVA-EPA (Estimate Potential Agency Impact), internet reachability, and likely exploitability:
