Estonian web security company Blackwall said Tuesday it raised $100 million in a Series C led by AVP at a $2.2 billion valuation. Executive chairman Roi Carthy said the valuation increased by 4 times since its 2025 fundraise.

Blackwall sells through hosting, cloud and managed service providers, which customize its security tools, set customer prices and share revenue with the company. Its tools distinguish legitimate visitors and AI agents from malicious traffic using software fingerprinting and models that analyze requests.

The company plans to expand across North America, Europe, Asia-Pacific and the Middle East. Its free tier shows traffic and threats; protection requires payment.
