Blackwall secures $100 million for expansion into 12 regions
The Estonian cybersecurity firm’s valuation reached $2.2 billion in the funding round led by AVP.

Estonian cybersecurity firm Blackwall announced a $100 million investment led by AVP, valuing the company at $2.2 billion. It will direct the money toward expansion into 12 regions in Europe, North America, Asia-Pacific and the Middle East.
The financing also drew participation from returning backers Tera Ventures, Dawn Capital and MMC Ventures. Speaking to TechCrunch, executive chairman Roi Carthy put the new valuation at four times the level reached in Blackwall’s 2025 funding round.
Blackwall reaches website customers indirectly: hosting businesses, cloud providers and managed service providers package its technology with their services. Its platform filters billions of daily requests and combines tools for managing bots, defending against DDoS attacks, web application firewalls, encryption and load balancing.
The business began under the name BotGuard after co-founder Denis Prochko encountered heavy automated traffic on a recipe website he had built. Bots were crowding out human visitors. Prochko and Nikita Rozenberg, the company’s chief executive, turned the remedy into a product.
