Not All Zero Trust Is Created Equal: Why Enterprises Host Their Own

What if you assumed your network was already breached?

That’s the starting point for Zero Trust. It’s a model built on verifying every user, securing every request, and removing trust based on network location.

But many access tools today don’t follow through. They route traffic through their own infrastructure, injecting third-party dependencies into your most sensitive systems. That might be fine for a demo or public site. But for internal dashboards, backend systems, or autonomous AI agents, it’s a liability.

You lose control over performance, privacy, and auditability while unnecessarily introducing latency and new attack surfaces.

The result? A growing gap between Zero Trust promises and what your setup can actually guarantee.

What Self-Hosted Really Means — and Why It Matters

Self-hosted Zero Trust isn’t about bringing everything in-house for tradition’s sake. It’s about keeping access control where it belongs — inside your environment, where your policies and data reside, and you control the enforcement path.

With Pomerium, you run the access gateway at your network’s edge. Every request is authenticated, authorized, and routed in real time, without ever leaving your infrastructure.

That means:

• You keep your data, policies, and logs fully in your control

• You reduce latency and remove unnecessary proxy hops

• You meet compliance without sacrificing performance or visibility

• You avoid hidden egress fees and third-party relays

For risk-sensitive environments, that level of control is foundational.

Control Isn't a Comfort. It’s a Security Requirement.

As credential-based attacks rise and threat actors scale their efforts with automation and AI, surface area becomes everything. The 2025 IBM X-Force report found that over 30% of breaches involved valid credentials — and cloud-hosted access tools often made it harder to detect and respond.

Keeping access enforcement local gives you the upper hand:

• Shrink your attack surface

• Maintain visibility into every identity-based action

• Prevent unauthorized access without relying on external services or third-party uptime

And for AI agents or high-throughput services? A self-hosted gateway is the only way to maintain Zero Trust at scale without bottlenecks.

How Leading Teams Put It to Work

Security-forward teams are already using self-hosted access to secure critical workflows:

• Finance and healthcare orgs enforce identity-based access to internal tools without sending requests to third-party clouds.

• AI infrastructure teams apply per-request policies to thousands of agent prompts per second with verified user context baked in.

• Platform teams swap out VPNs and static credentials for seamless, policy-driven access to staging, production, and CI/CD systems.

• Critical infrastructure providers prevent data from ever leaving their trusted boundary — even during policy checks.

When risk meets complexity, self-hosted Zero Trust becomes the clear path forward.

Built to Run With Your Stack

Pomerium isn’t a SaaS gateway pretending to be Zero Trust. It’s a real-time access layer designed to run with your infrastructure — not around it.

• Deploy anywhere — Kubernetes, VMs, cloud, on-prem

• Use your own identity provider — Works with any OIDC-compatible IdP

• Authorize every request — Enforce policy at the application layer in real time

• Stay in control of your data — Traffic never leaves your environment

• Scale with confidence — Designed for high-RPS, low-latency workloads

• No hidden overhead — Avoid egress charges, sidecar agents, and third-party relays

And with simple YAML-based policy config, security and platform teams can move fast without giving up control.

Built-In Compliance and Operational Trust

Self-hosted Zero Trust with Pomerium doesn’t just secure access, it makes compliance measurable and enforceable.

• Align with frameworks like SOC 2, HIPAA, ISO 27001, and NIST 800-53

• Enforce least privilege by design across humans, services, and AI agents

• Log every request with verifiable identity and context

• Eliminate blind spots caused by third-party routing

Security teams stay in control. Auditors stay happy. Data remains secure.
