Blackwall raises $100M Series C at $2.2B valuation for channel-based bot and AI-agent traffic security
Estonia-based Blackwall, which sells web traffic security tools to hosting, managed service and cloud providers, announced a $100 million Series C at a $2.2 billion valuation, four times its 2025 valuation. The round was led by AVP, with Dawn Capital, MMC Ventures and Tera Ventures participating. Blackwall uses a channel model: providers white-label and customize its tools, set their own prices and share revenue with Blackwall. The company filters bot traffic and AI agents using digital fingerprinting and its own AI models that assess request intent and behavior. It competes with Cloudflare, Akamai and Imperva. This is business and funding news with no direct threat or incident.
Technical Details
- Products cover threat intelligence, certificate management, DDoS protection and traffic routing.
- Digital fingerprinting identifies the software sending a request (the article cites Microsoft Office and Codex) to separate legitimate clients and AI agents from malicious bots.
- AI models deployed at customer endpoints analyze request intent and behavior to tell user-directed agents from malicious bots.
- The company foresees demand for systems that manage which AI agents get access, on what terms, and how they are authorized to make payments.
The funding will go toward expansion in North America, Europe, Asia-Pacific and the Middle East, and toward more security tooling for hosting, cloud and managed service providers.
