Continuous Monitoring of Vendor Security Posture
How to watch vendor security on an ongoing basis
Relying only on periodic assessments leaves the organization blind to changes in a vendor's security posture that happen between one assessment and the next, which is why continuous monitoring complements formal audits with signals that update in real time, such as security ratings based on external scans, alerts about known vulnerabilities in the vendor's exposed infrastructure, or mentions of its leaked credentials on dark web forums. This approach doesn't replace in-depth assessment, but it makes it possible to detect early warning signs, such as a vendor that suddenly exposes a vulnerable service to the internet, without waiting for the annual reassessment cycle. Continuous third-party rating tools have made this monitoring more accessible, although their value depends on someone actually acting on the alerts generated, instead of piling them up on a dashboard nobody reviews regularly.
