Blackwall quadruples valuation to $2.2B as websites wrangle an increasingly crowded internet

Web hosting and security providers can now offer AI agent traffic management tools to their clients under their own brand.

Estonia-based Blackwall, a provider of web traffic security tools for hosting providers, announced it has raised $100 million in a Series C funding round, bringing its valuation to $2.2 billion. This valuation represents a fourfold increase since its last fundraising in 2025. The company specializes in helping websites manage the surge in bot traffic, including AI agents. Led by AVP with participation from existing investors Dawn Capital, MMC Ventures, and Tera Ventures, the funding will be used to expand Blackwall's global operations and develop further security tools for hosting, cloud, and managed service providers. Blackwall employs a channel strategy, partnering with providers to offer its customizable security solutions under their branding, allowing these partners to manage client relationships and retain revenue control.

Blackwall's success and quadrupled valuation underscore the growing market demand for sophisticated bot and AI agent traffic management solutions, particularly within the web infrastructure sector. The company's channel-first approach differentiates it from larger players, enabling hosting and cloud providers to integrate and rebrand advanced security tools. This strategy empowers smaller providers to compete by offering specialized traffic control and security services, fostering a more dynamic ecosystem for website protection.

The company's focus on enabling hosting providers to control customer relationships and revenue streams, rather than competing directly, signals a potential shift in how web security is delivered. As AI agents become more prevalent, the ability for providers to offer granular control over bot access and traffic will become a key differentiator. Blackwall's investment in expanding its tooling suggests a future where managing AI interactions with websites is a core service offering.
