Solution

Protect every login from credential stuffing

Attackers replay stolen passwords against your login, signup, and password-reset endpoints at machine speed. ArxLayer raises the cost of automated abuse at the edge with rate limits, self-hosted challenges, and IP reputation, before a single bad request reaches your auth service.

The problem

Your auth endpoints are the easiest target you own

Login, signup, and reset flows accept untrusted input by design, which makes them the first place automated attacks land.

Credential stuffing at scale

Botnets replay leaked username and password pairs across thousands of IPs, looking for reuse.

Brute force and reset abuse

Password guessing, MFA fatigue, and forgot-password floods probe accounts and exhaust auth resources.

Fake signups and takeover

Automated account creation seeds fraud, and a single takeover exposes data, payments, and trust.

What you get

Layered defense built for auth flows

ArxLayer combines protected-area enforcement, bot challenges, rate limiting, and reputation so abuse is stopped early without blocking real users.

Protected-area enforcement

Wrap login, signup, and reset paths in a protection zone that applies challenges and limits before your origin.

Per-endpoint rate limits

Cap attempts per client on auth routes to throttle guessing and reset floods without throttling normal use.

Self-hosted challenges

Proof-of-work challenges raise the cost for automated clients and bar clients that don't execute the page.

IP reputation scoring

Clients seen abusing other surfaces are met with greylisting or denial; IPs are HMAC-hashed, raw IPs never leave the edge.

Verified crawler handling

Legitimate crawlers confirmed by reverse-DNS and forward-confirm are recognized, never by user-agent string alone.

Simulate before you enforce

Run controls in detect mode on live auth traffic, review what would block, then turn on enforcement.

How it works

Shield your auth flows in three steps

Route auth traffic through the edge, define what counts as abuse, and enforce with confidence.

Route auth through the edge

Point your domain at ArxLayer Edge so login, signup, and reset requests are inspected before the origin.

Define limits and challenges

Set per-endpoint rate limits and challenge thresholds, with reputation controls applied automatically.

Enforce and roll back safely

Switch on blocking from versioned policy, watch the impact in events, and reverse any change instantly.

FAQ

Questions, answered

How does ArxLayer stop credential stuffing?: It rate-limits attempts per client, serves self-hosted proof-of-work challenges to automated clients, and applies IP reputation so known-abusive sources are greylisted or denied before reaching your auth service.
Are the challenges a CAPTCHA?: No. They are self-hosted JavaScript proof-of-work challenges that raise the cost of automation and bar clients that don't execute the page. They are not human CAPTCHAs and not browser fingerprinting.
Will this block legitimate users trying to log in?: Not if you tune first. Run controls in detect mode on real traffic, review what would block, then enforce, with every policy change versioned and reversible.
Does ArxLayer see my users' passwords?: No. Enforcement happens at the request edge on signals like rate, reputation, and challenge results. The edge request path is local and in-memory, and credential validation stays at your origin.
