Cloud-Native Security in 2025: Why Runtime Visibility Must Take Center Stage

The Hacker News reports on 12 September 2025 that cloud-native security is evolving rapidly, with containers, Kubernetes and serverless technologies now the default for many organisations, expanding the attack surface beyond traditional security models. It argues that runtime visibility must take centre stage in CNAPPs, because while preventive controls catch theoretical risks, they cannot show whether those risks are active or exploitable in production.

By monitoring what workloads are actually running and how they behave, security teams gain a higher fidelity signal to prioritise real threats, answering questions such as whether a vulnerability is reachable in a live workload or if a misconfiguration creates a live attack path.

The piece notes that AI can aid prioritisation and response, citing Sysdig Sage™ as an example of an AI security analyst that helps analyse complex attack patterns and reduce mean time to resolution, while emphasising that AI augments rather than replaces human teams. It also highlights accountability challenges and the need to map findings back to code, ownership, and deployment context, with Sysdig describing a partnership with Semgrep to connect runtime vulnerabilities to their source code.

Finally, it forecasts consolidation over fragmentation, stating CNAPPs unify vulnerability management, posture assessment, threat detection and incident response, and that by the end of the decade containers are expected to power half of all enterprise applications, underscoring the push towards runtime-powered visibility, AI-driven assistance, and unified platforms.
