TL;DR: Vulnerability exploitation now accounts for 20% of breaches, credential abuse remains the top entry point, and third-party involvement in breaches doubled in the last year, according to Zero Networks and Verizon DBIR. The real lesson is that network weaknesses, trusted integrations, and over-privileged identities now blur together, so containment must be identity-aware, not perimeter-only.
Editorial analysis by NHI Mgmt Group, based on content published by Zero Networks: “Top Cyber Risks in 2026: How to Avoid Hidden Network Vulnerabilities”.
By the numbers:
- Vulnerability exploitation now serves as the initial access vector for 20% of all breaches, rising 34% year-over-year.
- Over 90% of security leaders express concern about VPNs leading to a security breach.
- 56% of organizations experienced at least one VPN-related cyberattack in the last year.
Key questions
Q: What fails when organisations still treat network access as a trusted boundary?
A: The failure is that authentication becomes a one-time gate instead of a continuous control.
Q: Why do exposed VPNs and trusted integrations create such high breach risk?
A: They create high risk because they often grant broad internal reach after a single successful authentication event.
Q: What are the signs that identity governance is failing at the network layer?
A: Common signs include unclear communication flows, broad access that remains unused for long periods, and teams that cannot explain why a user, workload or agent can still reach a given service.
Practitioner guidance
- Implement identity segmentation for network access Map every VPN, firewall, RMM, and cloud integration to the identities it can reach, then restrict each path to the smallest viable set of assets.
- Re-scope third-party access on a lifecycle basis Review vendor and MSP connections for broad standing reach, then remove access that is not tied to a current operational need and an explicit owner.
- Treat tokens and service accounts as governable identities Inventory OAuth tokens, API credentials, and service accounts alongside human accounts so revocation, scoping, and monitoring follow the same governance process.
Bottom line: Hidden network weaknesses increasingly become identity failures once a tunnel, token, or trusted integration grants broad internal reach.

Hidden network risk is now an identity governance problem: the decisive failure is not only exposure, but the assumption that authenticated access is inherently legitimate. VPNs, RMM tools, and cloud integrations all expand trust once a session is established, which means network defense and identity control can no longer be run as separate programmes. Practitioners should treat every path that grants broad reach as an identity decision, not just a connectivity decision.
A few things that frame the scale:
- The 2026 Verizon DBIR found that exploitation of software vulnerabilities became the leading initial access vector in confirmed breaches, accounting for 31% of incidents.
A question worth separating out:
Q: How should security teams balance segmentation and incident response after a credential compromise?
A: Use segmentation to limit what the compromised credential can touch, then contain the session, revoke the credential, and inspect adjacent identities and third-party paths for shared access. The goal is to prevent one stolen trust relationship from becoming a network-wide incident, especially where management planes and machine identities are involved.
