Estonia-based Blackwall has secured a $100 million Series C funding round led by AVP, pushing its valuation to $2.2 billion.
The company builds white-label web traffic security, DDoS protection, and bot management tools designed for cloud and hosting providers.
The Estonia-based company now reaches a valuation of $2,2 billion, an amount that is four times higher than its previous funding in 2025. The round was led by AVP, with participation from investors Dawn Capital, MMC Ventures and Tera Ventures.
How Blackwall works
Blackwall does not directly target website owners, but partners with companies that host websites and provide online services. These companies can customize Blackwall's tools, offer them to their customers under their own brand, and share the revenue.
The company initially offers free tools that show a website's traffic and threats, while charging for protection services. Among other things, its products help detect dangerous activity, manage security certificates, protect against attacks that bring down websites, and manage traffic.
