Continuous access control for financial institutions

Secure access for every user, device, vendor, machine, and AI agent across your branches, applications, and infrastructure.

Financial institutions can’t rely on one-time access decisions. A trusted device can fall out of compliance, a vendor’s access can become risky, or an AI agent can reach systems it shouldn’t. Portnox helps enforce access policies in real time, so access can be limited or removed when trust changes.

  • Proactive security across every access plane and identity
  • Limit or remove access when risk changes
  • Modernize NAC, RADIUS, and policy enforcement from the cloud

The Challenge

Access risk does not stop after login

A compliant device can fall out of compliance. A contractor may no longer need access. A certificate expires. An AI agent reaches systems it shouldn’t. Static controls weren’t built for any of this. Access needs to be continuously reviewed and enforced, not approved once and forgotten. 

THE LEGACY TOOL GAP

STATIC CONTROLS

Access is approved once and not revisited, leaving risk undetected until after the damage is done.

EXPANDED IDENTITY TYPES

Contractors, vendors, machines, service accounts, and AI agents all need the right access. Most tools weren't built for this reality.

LEGACY NAC LIMITATIONS

Built for network admission only. Modern environments require enforcement across apps, infrastructure, and remote access.

HOW PORTNOX CLOSES IT

CONTINUOUS EVALUATION

Access is evaluated continuously based on identity, posture, and risk — not just at the point of entry.

UNIFIED IDENTITY EXPERIENCE

One platform governs access for every identity type — human, machine, and AI — from a single policy engine.

NAC + ZTNA + TACACS+

Portnox unifies network, application, and infrastructure access in one cloud-native platform — no hardware required.

Access Control for the New Reality

AI agents are identities

The question is no longer just who has access, it is what has access, what can it do, and when should it stop. AI agents are now part of the access control conversation. They retrieve data, trigger workflows, and act on behalf of users or business processes. In financial environments, AI agents need the same governed access as any other identity. Portnox helps financial institutions unify user, device, vendor, maching, and AI agent access enforcement.

WHAT PORTNOX DOES

Continuous, context-aware enforcement

Portnox helps financial institutions move beyond one-time access approvals. Access is continually evaluated based on identity, device posture, policy, and risk, so teams can respond when something changes.

Secure

Secure users, vendors, devices, machines, and AI agents

restrict Access

Restrict, quarantine, or remove access automatically when requirements aren’t met

Cloud native Control

Replace legacy NAC and RADIUS complexity with cloud-native control

Visibility

Gain visibility into access decisions, device status, and policy enforcement

ZTNA glyph-teal-icn

Replace broad VPN access with zero trust application access

Built for Financial Services

Complex environments. Simplified enforcement.

Banks, credit unions, and payment processors have complex access environments, supporting a variety of locations, identities, device types, and sensitive systems without making access management harder for IT and security teams.

Portnox works with your existing infrastructure, deploying in days, not months. In addition to scalability and agility, Portnos helps financial institutions:

  • Apply consistent access policies across branches and locations
  • Control vendor and third-party access based on identity, role, device posture, and policy
  • See and manage devices before they become a risk
  • Reduce unauthorized access to sensitive systems and payment-connected environments
  • Modernize NAC, RADIUS, and access control from the cloud
  • Prepare for a future where machines and AI agents also need governed access

FAQs

Continuous access control means access is not treated as a one-time decision. Access can be checked and enforced as identity, device posture, policy, or risk changes.
Financial institutions manage access across branches, vendors, devices, applications, and sensitive systems. If risk changes after access is granted, they need a way to respond quickly.
Portnox enforces identity and access policies by using risk, posture, and compliance signals from integrated security and device management platforms. When a user, device, machine, or AI-related identity no longer meets policy, Portnox acts as the enforcement point restricting, quarantining, or removing access in real time.

Portnox helps enforce access policies across users, devices, machines, service accounts, AI agents, applications, and infrastructure access points, helping reduce risk from both people and systems.

Yes. Portnox can restrict, quarantine, or remove access when an identity, device, or connection no longer meets security or compliance requirements.
Portnox helps organizations modernize network access control with cloud-native NAC, RADIUS, device visibility, and policy enforcement.
