Blackwall has closed a $100 million Series C led by AVP, valuing the web traffic management platform at $2.2 billion. Existing backers Dawn Capital, MMC Ventures and Tera Ventures also joined the round.
That new valuation lands just weeks after Blackwall was reported to have reached a €1 billion valuation and placed fifth in TopTech 2026, Estonia’s annual ranking of the country’s 30 most valuable tech companies. The company is now using the fresh capital to push a bigger idea: not just security, but a broader traffic management ecosystem built around hosting providers.
Blackwall’s pitch is unusually embedded. Instead of sitting outside the network like many security vendors, it runs inside web hosting providers’ own infrastructure, where it can sort real visitors and legitimate automated traffic from malicious bots, attacks and abuse. The stack already covers bot mitigation, DDoS protection, web application firewall, load balancing, server-side encryption and management of agentic AI traffic. According to the company, it filters billions of requests per day.
The target market is big and messy. Blackwall says hosting is a $200 billion market and one that stays fragmented because infrastructure has to stay close to the businesses it serves. The company is betting that the providers who host much of the web will need its help as traffic becomes more automated and more agent-driven.
Blackwall plans to expand across 12 strategic regions in North America, Europe, Asia-Pacific and the Middle East. Its backers are clearly buying the same story: that the next layer of the web won’t be built for humans alone.
My take — AI-written commentary, not fact-checked reporting
This is the kind of deal that says more about the market than the pitch deck. Security firms love to talk about the future of the web; Blackwall is basically betting that the future is a flood of machines and that whoever sits closest to the pipes gets paid first. That’s not hype, that’s plumbing with a better valuation.
