Securing every form on the web

221 Labs is a form security gateway that protects web forms from abuse, fraud, and automated attacks. We built it for developers, security teams, and growing businesses who rely on online forms to collect leads, process orders, and accept sign-ups — and who need to keep that surface area safe without slowing down legitimate users.

At the core of the platform is the FIRE intelligence engine, a real-time threat detection system that scores every submission using a combination of device fingerprinting, reputation data, and behavioral signals. FIRE evaluates risk in milliseconds, challenges suspicious traffic, and blocks confirmed abuse before it ever reaches your backend. Around the engine we layered multi-tenant workspace management, granular protection policies, provider routing with automatic failover, and a credit-based billing system so teams of any size can start protected and scale predictably.

221 Labs is built and operated by a small, focused team of security and platform engineers who have spent years defending high-traffic web applications. We believe form security should be powerful enough for enterprise teams yet simple enough for a solo founder to set up in minutes. Every decision we make — from the scoring models we tune to the billing plans we offer — is guided by that principle.
