Will this slow my engineers down?

Not if you tier it. Gate only high/critical issues in CI and admission. Everything else is a visible warning with a fix link. Guardrails catch the foot-guns; runtime detections handle the edge cases. We’ve rolled this out in orgs shipping daily without increasing lead time.

We already have a SIEM—why add Falco/Kyverno/cosign?

SIEMs aggregate and search. You still need sensors (Falco/Tetragon/GuardDuty), prevention (OPA/Kyverno), and provenance/signatures (cosign/SBOM) to make the SIEM useful. Think sensors + policy + proofs feeding the SIEM, not replacing it.

How do we handle multi-cloud and hybrid?

Standardize the patterns: policy-as-code (Rego/Kyverno), eBPF runtime where you run Kubernetes, cloud-native findings into a common bus (Security Hub or Datadog), and evidence to a single immutable store. Use OpenTelemetry to normalize app security events across environments.

What about cost and alert fatigue?

Set a noise budget and SLOs up front. Start with a minimal ruleset targeting crown jewels, tune weekly, and only page for high-confidence detections. Shipping fewer, better alerts costs less than drowning your team and ignoring everything.
