Blackwall, an Estonian web traffic management and security company, announced a $100M Series C on October 20, 2026, at a $2.2B valuation. AVP led the round, and existing backers Dawn Capital, MMC Ventures and Tera Ventures participated. The company says the valuation makes it Europe's most valuable cybersecurity scaleup, a title contested by Exein, which has been valued at $1.7B.
The raise comes weeks after Blackwall crossed the unicorn line. It reached a valuation of roughly €1B in September 2026, which means the company moved from "unicorn" to a $2B-plus valuation in a matter of weeks.
What Does Blackwall Actually Sell?
Blackwall sells traffic filtering and management tools to web hosting companies, cloud providers and managed service providers, who resell them to their own customers. Its flagship product, GateKeeper, inspects incoming requests and blocks malicious bots, application-layer DDoS attacks and brute-force login attempts before they reach a customer's application.
The wider platform covers a web application firewall, load balancing, server-side encryption and management of traffic from AI agents. The company says it filters billions of requests daily across millions of websites. The company was previously called BotGuard and rebranded as Blackwall in March 2025, when it closed a €45M Series B.
The channel model matters. Blackwall does not chase individual site owners. It sells once to a host and reaches that host's entire customer base, which is how a company of its size can claim coverage of millions of sites.
How Did the Valuation Climb So Fast?
The valuation rose about fourfold since the 2025 round, according to Executive Chairman Roi Carthy. The company has not disclosed revenue, growth rates or the exact pre-money figure for the earlier round, so the multiple is hard to test from outside.
What the numbers do show is a premium for a specific thesis. Investors are paying for exposure to automated traffic, and Dawn Capital's Norman Fiore framed it as a "tsunami of agents" that will overwhelm infrastructure built for human visitors. A $2.2B price on a company that raised €45M roughly 19 months earlier implies that the next round had to price in much more than current earnings.
Follow-on participation from all three existing investors is a signal. Insiders rarely return at a fourfold step-up unless they believe the step is justified by internal metrics, though those metrics have not been published.
Why Is Bot Traffic Now a Hosting Problem?
Bot traffic has become a hosting problem because AI crawlers and autonomous agents generate requests that look increasingly like legitimate users, and hosts absorb the cost. Older bot defenses relied on separating humans from scripts. That distinction is blurring as agents browse, log in and transact on behalf of people.
CEO Nikita Rozenberg said the web is becoming "more automated, more distributed and more complex," while the infrastructure behind it "remains highly fragmented." Blackwall's pitch is a single layer that sits across that fragmentation and tells wanted automation from unwanted automation.
The hosting market itself is large. One estimate puts it at $150B in 2025, with a projection of $506B by 2033, though such forecasts vary widely by source and definition.
What Will the Money Fund?
The capital will fund expansion into 12 strategic regions across North America, Europe, Asia-Pacific and the Middle East, along with new traffic security products for hosting partners. AVP General Partner Warda Shaheen described Blackwall as "a security company that grows with the internet itself."
Regional build-out puts Blackwall into direct contact with larger incumbents in bot management, DDoS mitigation and web application firewalls, which already sell through enterprise contracts and content delivery networks. Its advantage is distribution through hosts. Its exposure is concentration: if a few large hosting partners renegotiate or build in-house, revenue could shift quickly.
Outlook
Blackwall now holds a $2.2B valuation, fresh capital and a stated plan to enter 12 regions. The open questions are commercial. Revenue has not been disclosed, the "most valuable European cybersecurity scaleup" claim is disputed, and the reseller model ties growth to the buying decisions of hosting companies. The next test is whether AI-agent traffic turns into a paid product line for hosts or remains a feature bundled into existing plans.
