Blackwall raises $100m at a $2.2bn valuation for hosts' traffic security

20 October 2026: Blackwall, an Estonian company that filters web traffic from inside hosting providers' networks, has raised $100 million in a Series C round at a $2.2 billion valuation. AVP led the round, with existing investors Dawn Capital, MMC Ventures and Tera Ventures taking part.

AVP's lead and a fast rise in value

Blackwall says the money will take it into 12 regions across North America, Europe, Asia-Pacific and the Middle East, and pay for new technology to handle automated and agentic AI traffic. Tech.eu notes that the company was reported a month earlier to have reached a €1 billion valuation and ranked fifth in TopTech 2026, the annual list of Estonia's 30 most valuable tech companies.

"Blackwall has built something rare: a security company that grows with the internet itself," Warda Shaheen, a general partner at AVP, told Tech.eu. Norman Fiore of Dawn Capital said: "A tsunami of agents will overwhelm infrastructure optimised for human traffic."

How the model works

Blackwall's pitch is about where its product sits. Instead of routing customer sites through a content-delivery network that competes with the hosting company for the same customers, it runs inside the provider's own infrastructure and stops unwanted traffic before it reaches the servers. That, the company says, cuts the provider's infrastructure costs and makes customers' sites faster. Its features cover bot mitigation, DDoS protection, a web application firewall, load balancing and server-side encryption, and are modular, so a provider can package and tier them as its own products and earn revenue from security without building it.

The company says bots now make up more than half of all web traffic and that 66% of that bot activity is malicious, and that small and medium-sized businesses depend on their hosting provider as the only practical route to securing a site at scale. It frames its next stage as a traffic management ecosystem around its network of hosting providers, connecting providers, infrastructure and technology.

What it means for hosting buyers

For a business choosing a host, the round is a reminder that the security layer in front of a site may be a third party's product sold under the host's brand. Asking which provider runs bot and DDoS filtering, and where traffic is inspected, is a fair question in any hosting tender. Our web hosting company category lists 200 companies.
