Blackwall has raised $100 million at a $2.2 billion valuation to expand its web-traffic management platform for hosting providers. The Estonia-based company confirmed the figures on its website; TechCrunch reported on October 20 that the Series C was led by AVP, with existing investors Dawn Capital, MMC Ventures and Tera Ventures participating.

Security sold through hosting providers

Blackwall’s distribution model centers on hosting companies, cloud providers and managed service providers rather than selling directly to individual websites. Partners can package its technology under their own brands and control pricing and customer relationships.

The company lists traffic analytics, bot mitigation, application-layer DDoS protection, a web application firewall, custom traffic rules and content caching among its modular components. It also offers API-based provisioning and management, allowing providers to integrate security packages into existing operations.

AI traffic adds another filtering problem

TechCrunch reports that Blackwall examines traffic to distinguish human visitors and legitimate AI agents from malicious bots and disruptive requests. That distinction matters for websites that want useful automated access without accepting indiscriminate scraping or attacks.

CEO Nikita Rozenberg described agent access permissions and payment authorization as a future opportunity. Those comments outline a potential market, not an announced agent-payment product.

The new capital will support geographic expansion and additional security tooling, according to TechCrunch. For infrastructure operators, the concrete development is fresh funding for a provider-controlled security platform; the financing itself does not establish how accurately its systems distinguish legitimate agents from hostile automation.
