Blackwall’s software runs inside the infrastructure of web-hosting, managed-service and cloud providers, screening requests before they reach the businesses those providers host. The company announced a $100 million Series C at a $2.2 billion valuation, Tech.eu reported on October 20.
Every request has to be sorted: a person or useful automated service should get through, while a malicious bot, denial-of-service attack or other abusive traffic should not. The platform pairs that filtering with a web application firewall, load balancing and server-side encryption.
This isn’t the usual model of moving a site’s traffic layer onto a hyperscale cloud or content-delivery network. Blackwall keeps the software in the provider’s own stack, which it says helps the provider protect customers without surrendering the relationship to a competing platform.
AI agents complicate the same sorting problem because automated traffic is no longer synonymous with unwanted traffic. Blackwall now includes AI-agent traffic management alongside its other controls and says the platform filters billions of requests a day.
AVP led the round, with existing investors Dawn Capital, MMC Ventures and Tera Ventures participating. Blackwall said the capital will support further platform development and a broader traffic-management ecosystem around its provider network.
The company plans to establish or expand operations across 12 regions spanning North America, Europe, Asia-Pacific and the Middle East. AVP said Blackwall’s position inside provider infrastructure already puts the software in front of millions of websites, giving the company reach through those provider relationships.
