How it works

Protection that runs around the clock.

Greymatter.io guards API traffic in, through, and out.

1
Drops in beside your apps

Greymatter.io runs next to the apps you already have, in the cloud, on premises, or on fully offline networks.

2
Write your rules once

Decide which apps can talk and where data can go. New apps pick up those rules the moment they join.

3
Runs and reports on its own

Greymatter.io enforces your rules around the clock and records each decision in one console.

API security FAQs

Greymatter.io secures API traffic at three points: the public edge, the calls between your internal apps, and data on its way out. The Greymatter.io platform verifies the identity of each caller, blocks known break-in methods, caps traffic floods, and shows where data goes. All of that runs from one console.

Greymatter.io places a checkpoint beside each app, so internal API calls get the same scrutiny as outside traffic. Each app proves its identity over an encrypted connection before another app will answer. Once enforcement is on, calls your rules do not allow get refused, so a compromised app is cut off from the rest of your systems.

Greymatter.io includes an App, API & AI Gateway, then adds identity checks, a web application firewall, traffic limits, and outbound controls inside your network. Teams get edge-to-exit API security without stitching separate tools together.

Yes. Greymatter.io shows every outbound call by name and flags sensitive data in requests and replies.

Greymatter.io runs in public clouds, private data centers, and disconnected networks with no internet access. One set of rules secures all of them.
