TL;DR: Runtime security vendors diverge less on detection than on whether findings become enforceable policy, whether detection logic is auditable, and whether cloud, Kubernetes, and workload signals correlate into one attack story, according to ARMO. That architectural split matters because teams leaving Upwind usually need prevention, transparency, and cross-layer context rather than another alert queue.

By the numbers:
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems, and organisations failing to scope AI access properly are 4.5x more likely to experience a security incident.
Questions worth separating out
Q: How should teams evaluate a runtime security platform beyond detection coverage?
A: Teams should test whether the platform converts observed behaviour into enforceable policy, whether the detection logic is auditable, and whether cloud, Kubernetes, and workload signals resolve into one attack story.
Q: Why does open detection logic matter in cloud runtime security?
A: Open logic lets security, audit, and platform teams inspect why a detection fired or missed, which improves trust and tuning.
Q: What do teams get wrong about runtime security in Kubernetes?
A: They often assume seeing risky behaviour is the same as preventing it.
Practitioner guidance
- Score platforms on enforcement conversion Evaluate whether a runtime finding can become a durable control such as a NetworkPolicy or seccomp profile without manual reconstruction.
- Demand explainable detection logic Ask vendors how detection rules are audited, reviewed, and validated when a signal fires or misses.
- Test cross-layer correlation with one attack story Run a scenario that touches cloud, Kubernetes, application, and workload signals, then verify that the platform presents one coherent attack story instead of separate findings.

ARMO's full comparison covers the operational detail this post intentionally leaves for the source:
- Vendor-by-vendor capability notes for detection, enforcement, and runtime reachability across Upwind, Sweet Security, Sysdig, Wiz, and Prisma Cloud
- Product-specific claims about open-source foundations, Kubernetes-native enforcement, and AI workload coverage
- The comparison table with the platform-by-platform feature breakdown that implementation teams use to shortlist tools
- The author’s reasoning on why ARMO, rather than the others, fits teams that want observable behaviour turned into policy

Upwind alternatives: what runtime security teams should evaluate now?

Runtime detection is no longer the differentiator. The category has largely converged on seeing suspicious behaviour. The real separation now is whether the platform can change the control state after it sees something, because detection without enforcement still leaves the buyer to close the loop. That means the evaluation lens should move from alert quality to governance impact, especially in Kubernetes and workload-heavy estates.
A question worth separating out:
Q: Should organisations prioritise correlation or reachability in runtime security?
A: If reachability is already comparable across vendors, correlation usually matters more because it determines whether analysts see one incident or four disconnected alerts. Reachability tells you what the platform can observe. Correlation tells you whether your team can act on the story quickly enough to limit impact.
