TL;DR: Cyber insurance carriers are tightening requirements around MFA, segmentation, identity-based access, and incident response as ransomware, AI-enabled attacks, and regulatory pressure drive premium increases of roughly 30%, according to Zero Networks and market research. The practical message is that underwriting now rewards control evidence, not just policy language, and identity governance is part of the premium conversation.
NHIMG editorial — based on content published by Zero Networks: Cyber Insurance Compliance: 5 Ways to Cut Premiums
By the numbers:
- 70% of organizations say their cyber insurance provider, rovider requires network segmentation.
- The article says attackers are targeting machine identities like service accounts, which now make up over 70% of networked identities.
Questions worth separating out
Q: How should security teams reduce cyber insurance premiums through identity controls?
A: Security teams should focus on controls that reduce breach blast radius and prove it with evidence.
Q: Why do service accounts matter in cyber insurance underwriting?
A: Service accounts matter because they often hold persistent, broad, and poorly reviewed access that can turn a stolen credential into wide internal reach.
Q: What do organisations get wrong about segmentation and insurance risk?
A: Many organisations treat segmentation as a networking exercise rather than a loss-limitation control.
Practitioner guidance
- Prove lateral-movement containment Document where microsegmentation blocks east-west movement for crown-jewel workloads, and retain test evidence that an initial compromise cannot reach adjacent systems without policy change.
- Inventory privileged and machine identities together Create a single control view for admin accounts, service accounts, API credentials, and automation identities so over-scoped access is visible before underwriting or renewal review.
- Apply just-in-time protection to privileged protocols Prioritise RDP, SSH, and WinRM for just-in-time MFA so elevated access exists only at the point of use and leaves an auditable trail for insurers.
What's in the full article
Zero Networks' full article covers the operational detail this post intentionally leaves for the source:
- How the segmentation and identity-segmentation model is positioned for underwriting evidence rather than general security architecture
- The specific control bundle the vendor recommends for demonstrating lower cyber insurance risk at renewal time
- The article's discussion of just-in-time MFA across RDP, SSH, and WinRM as an insurer-facing control story
- The vendor's framing of resilience, incident response, and compliance as parts of one premium-reduction argument

Insurance underwriting is now becoming a proxy assessment of identity governance. The article reflects a broader market change in which carriers want evidence that access is constrained, identities are segmented, and privileged paths are controlled before they price risk. That means IAM teams, PAM teams, and NHI owners are being judged on operational proof, not policy intent. Practitioners should treat insurance evidence requests as a governance test, not a paperwork exercise.
A question worth separating out:
Q: Who is accountable for proving cyber insurance control maturity?
A: Accountability should sit jointly with security, identity, infrastructure, and risk leadership because insurers evaluate the control stack as one operational posture. IAM owners should own identity evidence, PAM teams should own privilege controls, and security leadership should consolidate the story into renewal-ready assurance.
