TL;DR: Financial services firms are using Zero Trust Network Access to replace VPN-centric access with identity-driven, least-privilege controls, continuous auditability, and direct-routed connections, according to Appgate’s analysis of banking and capital markets deployments. The governance shift is clear: access models now have to satisfy both operational resilience and regulatory proof, not just connectivity.
Editorial analysis by NHI Mgmt Group, based on content published by Appgate: “Insights from the Field: How Financial Institutions Are Replacing VPNs with Zero Trust Access”.
Key questions
Q: What breaks when financial institutions keep broad VPN-style access in place?
A: Broad VPN-style access breaks least privilege because a successful login often exposes more of the internal environment than the business task requires.
Q: Why does Zero Trust access matter for regulatory accountability in finance?
A: Because regulators care about provable enforcement, not policy statements.
Q: What are the signs that access governance is failing in financial applications?
A: Warning signs include one person holding excessive control, irregular transactions not being questioned, and user access reviews that do not reflect actual job responsibilities.
Practitioner guidance
- Map and remove broad VPN trust zones Identify remote-access paths that still grant broad internal reach, then replace them with resource-scoped access rules for the systems users actually need.
- Enforce policy by identity, device, and context Require access decisions to consider user role, device posture, and contextual risk so privileged and third-party users do not inherit generic network access.
- Preserve audit evidence in the access path Log policy decisions, resource grants, and access denials in a way that supports compliance review, troubleshooting, and post-incident analysis.
Bottom line: VPN-centric access models are a poor fit for regulated finance because they expand internal reach beyond the business need.

ZTNA is becoming an access governance control, not just a remote-access replacement. In financial services, the question is no longer whether users can connect, but whether every connection is narrowly scoped, observable, and defensible under audit. That makes access architecture part of compliance evidence, not just IT plumbing. Practitioners should treat ZTNA as a governance layer for regulated access decisions.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should teams balance Zero Trust controls with performance in financial operations?
A: They should validate controls against production workflows, especially trading, custody, and customer-facing systems. Access governance that creates latency or brittle dependency chains will invite bypasses, so the access design has to preserve direct connectivity while keeping authorization narrow and observable.
