Estonian Startup Blackwall Hits $2.2B Valuation With $100M Raise to Tackle AI Bot Traffic
Blackwall has raised 100 million dollars in a Series C round that values the company at 2.2 billion dollars.
The round quadruples the valuation from its previous funding in 2025.
Why Hosting Providers Gain an Edge
The company sells its traffic filtering tools directly to web hosts rather than individual websites.
This channel model lets smaller providers offer advanced security without building it themselves.
Hosts can then bundle the features and set their own pricing for end customers.
Over the next 12 months many hosts may use this edge to compete better against larger cloud players.
AI Traffic Reshapes Web Security
Blackwall focuses on separating real visitors from growing volumes of AI agent bots and malicious traffic.
The funding will support expansion across North America, Europe, Asia-Pacific and the Middle East.
Founders expect agentic AI to drive most future web requests within a few years.
This shift creates new revenue streams for infrastructure firms that manage traffic well.
European startups like Blackwall show how regional ecosystems can produce global cybersecurity leaders.
