Solution

Security for every API you expose

ArxLayer protects public, partner, and internal APIs at the edge, before requests reach your services. Inspect payloads with OWASP CRS, enforce schema and tokens, identify machine callers, and shut down abuse, all from one control plane.

The problem

APIs are the surface attackers reach for first

Every endpoint you publish is a documented contract, and that makes it an easy target for scraping, credential abuse, and malformed input.

Malformed and malicious payloads

Injection and oversized or off-schema bodies slip past handlers that trust their callers.

Stolen and replayed tokens

Leaked keys and bearer tokens let attackers call your API as if they were a legitimate client.

Automated abuse at scale

Scrapers and brute-force clients hammer endpoints far faster than any human, draining quota and data.

What you get

Layered enforcement for the whole API surface

ArxLayer brings API Protection, Rate Limiting, Token Protection, and Bot Defense together at the edge, governed by one versioned, reversible policy.

OWASP CRS at the edge

Inspect every request body, header, and query with the OWASP Core Rule Set on the Coraza engine before it reaches your origin.

Schema-aware protection

Hold requests to the contract your API actually accepts, rejecting payloads that don't fit.

Token enforcement

Validate and scope API tokens at the edge so only authorized callers get through.

Machine-to-machine identity

Give service and agent callers verifiable identity, with no private keys in the enforcement layer.

Rate and quota limits

Throttle by client, route, and key to stop scraping and brute force without blocking real traffic.

Bot and abuse defense

Raise the cost for automated clients with self-hosted JavaScript proof-of-work challenges that bar clients which don't execute the page.

How it works

Protect your APIs in three steps

Route your API traffic through ArxLayer, tune safely on live calls, then enforce.

Route API traffic

Send your API endpoints through ArxLayer Edge. A balanced managed policy applies from the first request.

Tune in simulate mode

Watch what would block on real API calls, review the evidence, and apply scoped fixes before enforcing.

Enforce and adjust

Turn on blocking, rate limits, and token checks together, and roll back any change in seconds.

FAQ

Questions, answered

Does ArxLayer work for internal and partner APIs too?: Yes. Public, partner, and internal APIs all route through the same edge enforcement and the same control plane, with multi-tenant isolation.
Can it identify service and agent callers, not just users?: Yes. ArxLayer provides machine-to-machine identity and request-level enforcement for service and agent endpoints. It does not reason about model intent or detect prompt injection.
How does ArxLayer stop API abuse without blocking real clients?: Rate and quota limits, token validation, and proof-of-work challenges target automated abuse. You tune them in simulate mode first, so legitimate callers keep working.
