Blackwall Raises $100 Million, Valued At $2.2 Billion, As Web Hosts Race To Tame Bot Traffic

Estonia-based Blackwall announced Tuesday that it secured $100 million in a Series C round that values the company at $2.2 billion — roughly four times its worth at the last financing in 2025. The capital comes from lead investor AVP and returning backers Dawn Capital, MMC Ventures and Tera Ventures. Company leaders say the fresh money will be used to broaden operations across North America, Europe, the Asia-Pacific region and the Middle East, and to build more security offerings aimed squarely at hosting, cloud and managed-service companies.

The raise arrives as a growing share of web activity is driven by automated programs and increasingly sophisticated AI-driven agents, forcing hosting platforms and websites to defend themselves against denial-of-service strikes, indiscriminate scraping, bot farms and other unwanted requests. Big infrastructure providers have been dealing with those problems for years, and now face new complexities as autonomous software begins interacting with online services at scale. That dynamic has created both a headache and a business opportunity for firms that can police which machines are allowed through a site’s front door.

Blackwall’s pitch is to sell through partners rather than directly to end-user sites. Instead of marketing its stack to individual websites, the company supplies a suite of security modules to web hosts, managed-service outfits and cloud vendors, who then integrate the tools into their offerings and keep the client relationship. Company executives describe this as a partner-led model that lets hosting firms configure protections, bill clients under their own labels and retain control over pricing and support.

Under that model, Blackwall provides initial visibility at no charge so providers can see the volume and types of automated traffic hitting their infrastructure, then bills for defensive features. Its product set includes threat intelligence feeds, TLS certificate orchestration, mitigation for volumetric attacks and traffic steering. The firm also analyzes incoming requests to separate legitimate human visitors and authorized software from suspicious automated actors, using what it calls software-signature analysis and on-premise machine learning that runs near or inside customer networks to assess intent and behavior.

Executives argue the real prize will be managing the next phase of automation: software agents that act and pay on behalf of users. As those programs begin to complete transactions and make decisions for people, platforms will need mechanisms to control access, set permissions and authorize payments for third-party agents. A security consultant familiar with the hosting market said firms that let providers maintain the direct relationship with website operators, rather than interposing a separate security vendor, will hold an advantage — particularly where billing and custom policy controls matter.

Blackwall faces competition from larger players that have introduced their own controls for AI-driven crawlers and bots. But its leaders are betting the partner route will appeal to smaller hosts and MSPs that want to keep ownership of their customer base. The company’s management told TechCrunch the new funding will accelerate hiring, product development and geographic expansion as demand for automated-traffic management intensifies.
