Securing AI agents without AI.

Same input, same result, every time. That is what separates a security control from an opinion.

TRUSTED BY

AI security in production.

The default

Most AI security is another AI.

Cloud guardrails and marketplace add-ons ask a second model whether the first one behaved. That is an opinion, not a control.

Not with us

Zero Trust for AI.

One layer in front of every model you use. Same rules for all of them. Nothing is trusted because a model said so.

See how it works

A second LLM guesses.No LLM in the decision path.

It runs in a US cloud.Runs in your infrastructure.

It reads the chat, not the action.Every agent action checked.

In practice

Built for
depth.

Runtime security that follows an agent the whole way down, wherever you run it.

One MATVIS layer in front of every major model provider

Authority before action

Every action, before it happens

Which action, on whose authority, and where the instruction came from. Four enforcement points, from the prompt to the tool result.

Our firewall monitors your live traffic, proposes the rules it would enforce and holds them for your approval.

The threats

What it
stops.

Four ways an AI deployment goes wrong in production. Each one has a control that closes it, configured in the same place and reported in the same table.

See the product

Exfiltration01 / 04

Data walks out
through a door nobody opened.

Read the database. Send the email. Two permissions, one exfiltration path. MATVIS decides at the call: which tool, which arguments, whose authority.

How scoping works

Guardrails02 / 04

It says the wrong thing
to the wrong person.

Compliance violations on the way in. Brand damage and regulated content on the way out. Twenty-seven built-in topics plus your own, each tuned on your examples.

How topics are tuned

Retention03 / 04

You never get it back
once it has left.

Training sets. Provider logs. Prompt history you cannot reach or delete. The vault pseudonymises before the request leaves and restores it on the way back.

How the vault works

Evidence04 / 04

Nobody can prove
what happened.

Every verdict carries the check that fired, what it scored and the config it ran under. Out to Splunk and OpenTelemetry. Back in through the API when your SOC overrules it.

What the log contains

An agent with tool access reaching systems it was never scoped for

Inbound and outbound traffic screened against the same content policy

Where a prompt ends up once it leaves your network

A blocked prompt injection with every check that ran on it

Why now

AI is the #2
global business risk.

Last year it was #10. Three things moved it, and all three land in your stack in 2026.

Architecture

A third of enterprise apps will act on their own by 2028. Nothing in your stack was built to authorise them.

Gartner, Oct 2025

02

Attacks

Prompt injection reports rose 540% year over year. A security layer that is itself an LLM reads attacks the same way.

HackerOne, 2025

Regulation

AI Act high-risk duties apply. Under NIS2 and DORA, an external model endpoint is a third party you answer for.

Our clients trust us with their most sensitive compliance data. With MATVIS, we guarantee that this data is protected at every step.

With MATVIS as our technology partner, our customers benefit from enterprise AI while enforcing GDPR compliance at the same time.

Open Systems

MATVIS runs entirely on our own infrastructure, responds orders of magnitude faster than anything else we measured, and protects more reliably. We did not expect to get all three at once.
