What is runtime monitoring?

Observing the application in production to detect or block attacks and confirm which vulnerabilities are actually exposed.

By Cláudia FernandesUpdated 2026-10-02

Runtime context answers the question static analysis cannot: is this vulnerable code path actually reachable in the deployed system, behind authentication, or exposed to the internet? That reorders a backlog fast.

Some tools go further and block malicious requests in-process. That is a different operational commitment from scanning, since it sits in the request path, so latency and failure behavior become your concern.

What to look for

Whether it observes only or actively blocks
Deployment model (sidecar, agent or in-process library) and its overhead
Whether runtime signals feed back into finding prioritization
Failure behavior if the runtime component becomes unavailable

Best 6 code quality, security and code review tools with runtime monitoring

Every tool in the directory whose documentation covers this. Shown in a random order that changes on every visit, so no tool gets an advantage from its position.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.
