Runtime Is the Real Defense, Not Just Posture
Sysdig, Friday, September 4th, 2026
Sysdig argues posture scanning is a still image of a moving target and that runtime security should be the starting point.
Sysdig opens with the analogy of defending a moving target by studying a still image, which it says describes most cloud security strategies today.
Tools that scan for misconfigurations or check policy alignment are useful but cannot see what is unfolding in real time, and in the cloud real time is everything.
Cloud-native architecture compounds the problem: containers spin up in seconds, Kubernetes orchestrates millions of changes a day, and serverless compute can vanish after milliseconds, creating blind spots legacy endpoint tooling cannot cover.
The recommendation is to flip the usual order and build the defense outward from runtime security rather than treating it as an add-on to posture management.
