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.
NHIMG editorial — based on content published by Zero Networks: Assessing Cybersecurity Maturity, how to benchmark your defenses in 2026
By the numbers:
- When 86% of cyber incidents disrupt business operations, leaders need a maturity model that measures containment, not just policy coverage.
- A single compromised host gives attackers access to 100% of an organization’s environment within just two hops, showing why internal reachability is the real control boundary.
Questions worth separating out
Q: How should security teams benchmark maturity if they care about breach containment?
A: Use a risk-weighted model that scores how well the environment limits blast radius after initial access.
Q: Why do service accounts and privileged pathways matter so much in resilience assessments?
A: Because identity controls determine what an attacker can do after they get inside.
Q: What breaks when network visibility is only updated at audit time?
A: Blind spots grow between reviews.
Practitioner guidance
- Benchmark containment, not just maturity scores Rebuild assessment criteria around internal reachability, segmentation granularity, and the number of assets a single foothold can access.
- Map standing access across human and non-human identities Inventory privileged accounts, service accounts, and administrative protocols that remain permanently open, then rank them by blast-radius potential.
- Tie discovery to enforcement Require asset discovery, identity visibility, and communication-path updates to trigger policy changes automatically instead of waiting for periodic reviews.
What's in the full article
Zero Networks' full article covers the operational detail this post intentionally leaves for the source:
- A scored maturity questionnaire that breaks network resilience into containment, identity governance, visibility, and automation.
- A framework-by-framework comparison of NIST CSF, CIS Controls, ZTMM, ISO 27001, ITIL, and CMMC for benchmarking posture.
- Guidance on how the Segmentation Maturity Quiz translates responses into a tailored resilience benchmark.
- A practical explanation of how Zero Networks positions microsegmentation and just-in-time MFA within its own architecture.

Blast radius, not aggregate maturity, is the relevant security metric. Mature programmes can still fail if they measure governance consistency while ignoring how far an attacker can travel after the first foothold. The article is right to frame resilience around containment because real-world incidents become costly when lateral movement outruns response. Practitioners should assess control effectiveness by internal reachability, not by a blended posture score.
A few things that frame the scale:
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, according to The State of Non-Human Identity Security.
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, with 38% reporting no or low visibility and 47% reporting only partial visibility.
A question worth separating out:
Q: Who is accountable when breach containment fails despite good-looking maturity scores?
A: Security leaders remain accountable for the control outcomes that matter, not the score itself. If a programme allows broad internal reach, standing privilege, or delayed policy enforcement, the organisation has accepted residual blast-radius risk. Frameworks such as the NIST Cybersecurity Framework and Zero Trust maturity models are meant to expose that gap, not excuse it.
