Network security tools in 2026: are identity controls keeping up?

TL;DR: Network security tools are positioned as visibility, detection, and prevention layers for modern infrastructure, but the blog’s real message is that security stacks still need tighter identity governance to match network control ambitions, according to Zluri. The issue is not more tools alone, but whether access, secrets, and lifecycle processes keep pace with how those tools are deployed.

Questions worth separating out

Q: How should security teams govern identities that operate network security tools?

A: Security teams should treat those identities as non-human identities with the same ownership, lifecycle, and privilege expectations as any other critical account.

Q: Why do network security tools still leave organisations exposed to access risk?

A: Because traffic inspection does not eliminate excessive privilege, shared credentials, or weak offboarding.

Q: What breaks when service accounts are not included in security reviews?

A: The review process misses the identities most likely to persist, accumulate privilege, and move between tools without business ownership.

Practitioner guidance

• Inventory the identities behind every security tool Document which service accounts, API keys, certificates, and admin roles operate firewalls, cloud filters, DNS controls, and related platforms.
• Tie tool coverage to identity lifecycle controls Review whether provisioning, rotation, and offboarding are enforced for the identities that administer network security tooling.
• Test for over-permissioned access paths Validate whether privileged identities can reach multiple security layers with the same credentials or tokens.

What's in the full article

Zluri's full blog post covers the product-oriented detail this analysis intentionally leaves for the source:

• The full list of 10 tools and their named feature sets, useful if you are comparing product coverage side by side.
• The vendor's own framing of firewalls, cloud security, DNS protection, and switching platforms across the 2026 shortlist.
• The original conclusion and positioning language used to support the roundup.
• The article's context for buyers who want a market list rather than an identity governance analysis.
