Blackwall, operating as BotGuard OÜ, is a security infrastructure company that protects web ecosystems from automated threats including malicious bots, crawlers, and scrapers. The company is legally registered in Estonia and headquartered in Tallinn.

The company's core offering focuses on mitigating automated threats for hosting service providers, cloud platforms, and enterprise networks. Their solutions are designed to defend against bot-based attacks while optimizing performance, operational costs, and revenue for hosting environments. The platform provides protection for millions of sites and applications globally.

Blackwall's approach is engineered for technical audiences, specifically hosting service providers and site owners who need to secure their infrastructure against automated attacks. The company positions itself as a security infrastructure provider rather than a traditional application security vendor, focusing on the unique challenges faced by hosting environments and cloud platforms.

The company recently raised a EUR 45 million Series B funding round led by Dawn Capital and rebranded from BotGuard to Blackwall. Their investor base includes Dawn Capital, MMC Ventures, Tera Ventures, 01 Expeditions Fund, and Red Dawn Ventures. The company operates with a distributed leadership team covering operations across multiple regions including APAC, with offices in Estonia serving as their headquarters.
