TL;DR: Cybersecurity maturity in 2026 is increasingly measured by whether an organisation can contain a breach, not whether it can produce a reassuring aggregate score, according to Zero Networks. The article argues that network resilience depends on containment-first architecture, identity and access governance, visibility, and policy automation, because business disruption follows lateral movement, not initial access.
Editorial analysis by NHI Mgmt Group, based on content published by Zero Networks: “Assessing Cybersecurity Maturity: How to Benchmark Your Defenses in 2026”.
By the numbers:
- 86% of cyber incidents disrupt business operations, according to Zero Networks.
- Adversaries begin moving laterally in as little as 27 seconds, according to Zero Networks.
- A single compromised host can give attackers access to 100% of an organisation's environment within just two hops, according to Zero Networks.
Key questions
Q: What breaks when cybersecurity maturity is measured by a single aggregate score?
A: A single score can hide severe exposure in the parts of the environment that determine how far a breach spreads.
Q: Why does standing privileged access increase blast radius even in segmented networks?
A: Because segmentation only helps if privileged identities cannot still move freely inside the environment.
Q: How do security teams know whether containment is actually working?
A: They should test whether the identity can still execute privileged actions after revocation, not just whether the API call succeeded.
Practitioner guidance
- Benchmark by reachable blast radius Replace single-number maturity scoring with assessments that measure how far a compromised asset can move across the environment.
- Map privileged pathways to internal reachability Document which privileged accounts, service accounts, and administrative protocols can still traverse internal segments after a foothold is established.
- Test containment before incident response Use controlled simulations to confirm that segmentation, identity controls, and policy enforcement reduce lateral movement automatically, not after manual intervention.
Bottom line: Cybersecurity maturity cannot be judged accurately if an organisation still allows broad internal movement after initial access.

Blast radius is the real maturity metric: programmes that cannot contain internal spread are over-credited by aggregate scoring. A healthy governance score does not matter if one foothold can still reach critical assets. The practitioner conclusion is that resilience must be measured by reachable scope, not by comfortingly averaged maturity.
A question worth separating out:
Q: What is the difference between network segmentation and identity governance in breach containment?
A: Segmentation limits where traffic can go, while identity governance limits who can move there and under what conditions. Both are required because an attacker with valid credentials can still exploit broad internal access if identity policy remains standing open. Strong containment depends on both network boundaries and access boundaries.
