About API Armor
Protecting signup forms from spam, abuse, and malicious attacks — so developers can ship with confidence.
Security that gets out of the way
Every developer should be able to build secure applications without constantly worrying about spam, bots, and malicious attacks.
We've seen too many promising applications fail due to security vulnerabilities that could have been prevented. That's why we built API Armor — to give developers the tools they need to protect their signup forms and focus on building amazing applications.
Comprehensive threat detection
API Armor protects your signup forms through advanced threat detection, real-time analysis, and intelligent blocking mechanisms.
Argus — Multi-Layer Fingerprinting
Our flagship service fingerprints every visitor across seven layers — from the TLS handshake to the canvas pixel — so you can catch automation, anti-detect browsers, and rotating proxies that slip past everything else. Even when cookies are cleared and IPs rotate, fuzzy matching keeps recognising the same client.
