Blackwall's $100M Series C Fuels AI Traffic Security Expansion
Blackwall raised $100 million in Series C funding at a $2.2 billion valuation to scale its security platform for hosting providers grappling with complex AI-driven web traffic.
Blackwall, a Tallinn-based cybersecurity company, raised $100 million in a Series C funding round at a $2.2 billion valuation. The capital will fuel its expansion into 12 strategic regions and the development of new traffic security products for hosting and cloud providers.
Founded by Nikita Rozenberg and Denis Prochko after their recipe website was plagued by bot traffic, Blackwall now provides critical security tools to hosting providers, managed service firms and cloud companies. The company is scaling its platform to meet rising demand as AI agents reshape web traffic patterns.
Funding and Market Position
Blackwall secured $100 million in Series C funding led by AVP. The round values the company at $2.2 billion, a figure that positions it as Europe's most valuable cybersecurity scaleup. This title is contested, however, by other firms like Exein, which holds a $1.7 billion valuation.
The funding will support a major geographic push. Blackwall will expand into 12 strategic regions across North America, Europe, Asia-Pacific and the Middle East.
Platform Innovation for AI Traffic
The wider adoption of AI agents is adding significant complexity to traffic management and security. Blackwall's technology is designed to address this new landscape by distinguishing legitimate visitors from automated traffic and malicious bots.
The platform employs digital fingerprinting and proprietary AI models to parse traffic. It identifies legitimate users, authorized AI agents and malicious bots. CEO Nikita Rozenberg stated the company intends to develop additional tools to help providers manage AI agent interactions with websites.
"The web is becoming more automated, more distributed and more complex, but the infrastructure that powers it remains highly fragmented," Rozenberg said.
Provider-Centric Business Model
Blackwall operates on a channel approach, enabling hosting and cloud providers to integrate security without building the underlying technology themselves. Providers can customize and rebrand Blackwall's security suite instead of the company selling directly to end users.
The strategy allows hosting companies to retain client relationships while offering integrated security solutions. Blackwall aims to give infrastructure providers a single, comprehensive layer for traffic management.
The platform's core features include:
Blackwall uses a revenue-sharing model. It provides free traffic monitoring to partners while charging for active protection services. This model is designed to grow with the internet's expansion.
Warda Shaheen, an investor, highlighted this adaptability. "Blackwall has built something rare: a security company that grows with the internet itself," Shaheen said.
Closing on its product roadmap, Blackwall will develop new tools to help providers manage AI agent interactions with websites.
