- Estonian company Blackwall makes security tools that help hosting providers and websites tell apart bot traffic, especially visits from AI agents.
- The company said it raised $100 million in a Series C round and that its valuation is $2.2 billion. Roy Karti, Blackwall's executive chairman, said the valuation has grown 4 times since its investment before 2025.
- Blackwall does not sell directly to websites. It offers a bundle of tools to hosting, managed service, and cloud providers. These providers sell to their own customers under their own brands and share revenue with Blackwall.
- Customers can use a free tier that shows traffic and threat status. Real protection features and tools require payment. The company said it uses digital fingerprinting and its own AI models to separate requests sent by people from malicious bots. This is the company's own explanation, and the source does not include independent verification results.
O: This may be useful for a small website operator who pays a monthly fee to a hosting provider and wants to ask the provider whether it offers bot management or AI agent access control options when bot traffic increases.
X: Before relying on the company value of $2.2 billion and its protection performance, note that these are claims made by the company and its executives, and the source does not include independently verified data.
