Estonia-based Blackwall raises $100 million at $2.2 billion valuation
Estonia-based Blackwall raised $100 million in a funding round that values the company at $2.2 billion.
Blackwall makes tools that help web hosting, cloud and managed service providers identify and manage web traffic for the sites they support.
Its tools protect against threats such as DDoS attacks and malicious bots, while allowing providers to offer the services under their own brands.
The company also aims to distinguish legitimate AI agents from harmful automated traffic as more software interacts with websites.
This matters because websites and their infrastructure providers face rising volumes of automated requests, and Blackwall says its platform can help manage them.
AVP led the Series C, with existing investors Dawn Capital, MMC Ventures and Tera Ventures also taking part.
Blackwall plans to expand across North America, Europe, Asia-Pacific and the Middle East, and develop more security tools for providers.

What people are saying
Our ambition is to build the traffic management ecosystem that brings those worlds together. This funding allows us to expand globally, deepen our platform and give hosting and infrastructure providers the technology they need to participate in the next generation of the web.
It is already the layer in front of millions of websites, and as more of the web's traffic comes from agents, the company in that position becomes indispensable. That's why we're leading this round.
this funding round increased the company’s valuation by 4 times since its previous fundraise in 2025.
