Stop bots before they touch your backend.
Fortt protects your app from abuse and network threats at the edge — with just 3 lines of code, detect bots, classify risky traffic, and block suspicious requests before they reach your API.
Stop risky requests without blocking legitimate users.
When Fortt detects suspicious behavior, it doesn't block blindly — it engages the user or client with an adaptive verification challenge that confirms intent before granting access.
Smart detection
Challenges only trigger when Fortt's behavioral signals detect unusual patterns — velocity spikes, new IP ranges, or compromised sessions.
Adaptive challenges
Fortt can present logic puzzles, CAPTCHA-free interactions, or lightweight proof-of-work tasks that are hard for bots but frictionless for users.
Instant verification
Legitimate requests pass seamlessly within milliseconds, ensuring no UX disruption.
Developer control
Configure thresholds, customize challenge types, and monitor Fortt’s actions with full transparency.
Adaptive learning
Challenge difficulty adjusts dynamically based on prior responses and risk level.
Live visibility
All detection and challenge events are logged in your dashboard.

Seeing a spike on `/auth/login` from AS9829. Legit?
Good catch — Fortt already flagged it. Our risk model detected automation patterns and is serving adaptive challenges only to suspicious sessions.
So legit users aren’t affected?
Exactly. Real users pass seamlessly, while high-risk ones face verification. We’ll keep monitoring and post an update if behavior shifts.
Simple, transparent pricing.
