London-based web traffic security company Blackwall has raised $100 million in a Series C round at a $2.2 billion valuation, as Vestbee was informed. AVP led the round and joins existing investors Dawn Capital, MMC Ventures and Tera Ventures. The company says the valuation makes it Europe’s most valuable cybersecurity scaleup to date.
- Founded in 2019 by Nikita Rozenberg and Denis Prochko, Blackwall runs inside the infrastructure of web hosting, cloud and managed service providers rather than selling directly to website owners.
- Its platform covers bot mitigation, DDoS protection, a web application firewall, load balancing and server-side encryption. It also manages traffic from AI agents, which the company describes as a fast-growing share of internet activity.
- The system separates real visitors and legitimate automated traffic from malicious bots and attacks, filtering billions of requests per day.
- The platform helps hosting providers save money and make money. It blocks unwanted traffic before it reaches their servers, cutting infrastructure costs. Providers can also sell Blackwall’s security features to their own customers under their own brand, which gives them a new revenue stream without building the technology themselves.
Details of the deal
- Blackwall will use the funding to establish and expand operations in 12 regions across North America, Europe, Asia-Pacific and the Middle East.
- It also plans to add new traffic security capabilities so that providers can cover more of their customers’ needs through a single infrastructure layer.
“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," explains Nikita Rozenberg, co-founder and CEO of Blackwall.
