01Introduction
If you can fix only a tenth of your vulnerabilities this quarter, which tenth? Traditional vulnerability management answers with CVSS severity. RBVM answers with actual risk to your business.
02What is RBVM?
Risk-based vulnerability management (RBVM) is an approach to prioritization that ranks each vulnerability by the likelihood it will be exploited in your environment and the impact if it is, rather than by technical severity alone.
Inputs typically include exploit availability, evidence of active exploitation from threat intelligence and CISA's KEV catalog, exploit prediction scores such as EPSS, asset exposure and criticality, and whether the vulnerable code is reachable.
03How RBVM works
RBVM adds context to every finding before it is ranked.
- 1.
Collect findings
Aggregate results from scanners, pentests, code review and cloud posture tools.
- 2.
Add threat context
Tag which vulnerabilities have public exploits or are being exploited in the wild.
- 3.
Add asset context
Weight by internet exposure, data sensitivity and business criticality.
- 4.
Rank and route
Produce one ordered list, with the top items routed to owners on tight deadlines.
04Threats and risks
RBVM is only as good as its context.
Garbage-in scoring
Missing asset ownership or wrong criticality puts the wrong items at the top.
Theoretical exploitability
'An exploit exists somewhere' is weaker evidence than 'this exploit works against this endpoint'.
Ignoring chained risk
Two medium findings that combine into a critical attack path each look low-risk on their own. Exposure management looks at the chain.
Long-tail neglect
Deprioritized items still accumulate and can be picked up by a new exploit.
05How Parameter helps
Parameter supplies the strongest risk signal there is: proof.
Exploited, not predicted
The pentesting agents confirm exploitability against your running application.
Reachable, not just present
Supply Chain checks whether your code actually calls the vulnerable function.
Attack paths across the cloud
Cloud Security ranks misconfigurations by real attacker reach to your data.
