Many companies still rely on IBM i for its performance and stability - but traditional security models like VPNs and perimeter firewalls no longer hold up. The new standard is Zero-Trust: never trust, always verify. And Sitemule delivers it natively on IBM i.

Read the full whitepaper to see how Zero-Trust turns IBM i into a future-ready platform.

This whitepaper from System & Method introduces a Zero-Trust architecture built around:

• NGINX as a hardened gateway with SSL offloading and DDoS protection

• OIDC identity providers (like Keycloak) for secure, federated login with multi-factor authentication

• IceBreak, a native IBM i web engine that verifies JWT tokens locally for high-speed, secure access

It also includes Let’s Encrypt integration for fully automated SSL certificate management and token-based partner access without VPNs.

Rather than replacing your IBM i environment, this approach modernizes it - securely, efficiently, and without rewriting code. The result: faster development, better compliance, and lower operational costs.

The architecture is already helping organizations reduce attack surfaces, accelerate delivery, and extend IBM i to the cloud and external ecosystems - with zero disruption.
