Netacea is Bot and Agent Trust Management for commerce and content. We help enterprises tell the difference between good bots, bad bots, and AI agents, and turn that into protected revenue instead of a security headache. Under the hood, it's a server-side, AI-driven platform that reassesses every request in real time. Our unique agentless approach means no manual rule-writing, no code deploys, and one of the lowest false-positive rates in the category. That translates to fewer blocked customers, less firefighting, and a single view across your whole estate instead of stitched-together point tools. Working with us isn’t just about our patented technology. Behind the platform sit two dedicated human teams that understand the threats you face better than anyone else. Threat researchers who infiltrate the forums where attacks are actually planned, and consultants who tune the system and interpret results with you. So you get industrial-strength detection, with the human judgement to act on what matters. We're not guessing at this: we created the BLADE framework, now adopted by OWASP as the industry standard for business logic abuse — so when you work with us, you're working with the team that shapes how the sector defends against the threats you face.
