Blackwall Raises $100M at $2.2B Valuation
Estonian cybersecurity startup Blackwall, formerly BotGuard, has raised $100 million in a Series C funding round, quadrupling its valuation to $2.2 billion. The round was led by AVP, with participation from existing investors Dawn Capital, MMC Ventures, and Tera Ventures. Blackwall builds web traffic security tools for hosting, cloud, and managed service providers, focusing on bot mitigation, DDoS protection, web application firewall, load balancing, server-side encryption, and management of agentic AI traffic. The company uses a channel approach, offering white-label security bundles under providers' own branding, and employs digital fingerprinting and AI models to differentiate legitimate AI agents from malicious bots. The funding will accelerate expansion into a global traffic management ecosystem across 12 strategic regions in North America, Europe, Asia-Pacific, and the Middle East, competing with Cloudflare's AI Crawl Control, Akamai, and Imperva, but differentiating by not selling directly to website operators.
