TL;DR: 39% shows how far remote code execution rose in Synack’s 2026 data, which also records 17% brute force and 8% content injection increases. AI agent privileges, edge systems, and developer environments need tighter continuous discovery because fixed review cycles are now easier to outrun.
Editorial analysis by NHI Mgmt Group, based on content published by Synack: “The 2026 State of Vulnerabilities: What the Data Misses, According to Our Red Team”.
Key questions
Q: What breaks when security testing is limited to a fixed scope?
A: Scoped testing misses how separate weaknesses combine across systems, so organisations can certify a portal or service while leaving the real attack path untouched.
Q: How do teams know whether an exposure window is too long?
A: If an issue can be exploited before a normal review or patch cycle completes, the window is already too long.
Q: Why do AI agents complicate privilege governance?
A: AI agents complicate privilege governance because they can request access, use tools, and execute actions faster than human review cycles.
Practitioner guidance
- Expand validation beyond the scoped perimeter Include edge appliances, internal APIs, staging environments, and newly created developer assets in your discovery and verification process so the untested portion of the attack surface does not become the default target set.
- Classify AI agents as governed identities Assign each agent an owner, explicit permissions, approved data sources, and a revocation path so model behaviour does not substitute for identity controls.
- Tighten authentication boundaries against automated probing Monitor for brute force patterns, rate-limit exposed login surfaces, and review whether public-facing authentication flows can withstand machine-speed attacks.
Bottom line: The core risk is not only more vulnerabilities, but more exposure in places that formal testing does not fully cover.

Coverage gap is the real attack surface: the most dangerous exposure is often not the vulnerability class itself, but the untested portion of the environment where it can exist unnoticed. Synack’s data is useful precisely because it is scoped, yet that same scoping creates a false comfort if teams mistake tested findings for complete risk visibility. The practitioner conclusion is simple: governance must include the assets you do not routinely assess.
A question worth separating out:
Q: What should organisations do when AI access, edge devices, and developer systems all expand at once?
A: They should treat the combined environment as a single governed attack surface, not three separate programmes. That means shared ownership, continuous discovery, and prioritisation by reachability and privilege, because attackers will move across those boundaries much faster than internal teams usually do.
