Zero Trust runtime security

From connecting services to securing them while they run.

Greymatter.io has matured into a Zero Trust runtime security platform.

Since 2015
Connecting and protecting services
Our roots are in securing how services talk to one another, for programs whose systems could not fail.
Today
Securing apps, APIs, and AI workloads while they run
Security happens the moment a request is made, before damage is done.
One product
Verifies, encrypts, inspects, and records each request
Teams no longer need a separate tool for each of those jobs.
AI moved in. Enforcement moved out.

Control. Secure. See.

Most architectures predate AI agents. Three pillars close the gaps a stitched-together stack leaves open.

Seven capabilities, built in.

Each capability shares the same identity, policy, and record. Nothing to integrate, nothing extra to buy.

WAF
Attacks stopped before they reach your apps.

Each request is checked against the OWASP Core Rule Set, from outside and inside your network.

Why it matters
  • Move faster. Live the second you deploy.
  • Stop more. Catches SQL injection, XSS, and more.
  • Prove it. Each match is logged for your audits.

Zero Trust runtime security FAQs

Greymatter.io is a Zero Trust runtime security platform. One product secures apps, APIs, and AI agents with a gateway, mesh, identity, WAF, AI guardrails, and forensic auditing. Greymatter.io runs on Kubernetes, OpenShift, RKE2, and Amazon cloud servers, in the cloud, on premises, and on fully offline networks.

Zero Trust runtime security protects apps, APIs, and AI agents while they run. Greymatter.io checks who is calling, encrypts the connection, and inspects each request before it reaches the app. Greymatter.io also records who did what, and when.

Keep them. SASE and ZTNA secure the edge of a network. Greymatter.io secures what happens inside, between apps, APIs, and AI agents.

Greymatter.io gives an AI agent its own identity and its own rules. A new AI agent gets its own identity, and Guardrails inspects its calls to tools and MCP servers. AI Guardrails screen prompts and responses, and the record names the user the AI agent acted for.

Defense, national security, financial services, and telecommunications teams use Greymatter.io. Greymatter.io is FIPS 140-3 validated (CMVP #5191), and one customer saw 62% faster audits.
