Blackwall, the Estonia‑based security platform, secured a $100 million Series C round, lifting its valuation to $2.2 billion as it expands tools that protect hosting providers from rising bot and AI‑driven traffic.

Estonian security startup Blackwall announced a $100 million Series C financing round that pushes its valuation to $2.2 billion, positioning the firm as a leading defender against increasingly sophisticated bots and AI agents targeting hosting providers.

Funding round details

The round was led by a consortium of venture capital firms, with participation from existing backers. Blackwall’s CEO highlighted that the capital will accelerate product development and expand the company’s global sales force.

Why bots and AI agents matter now

Websites and hosting platforms are facing a surge in automated traffic that mimics human behavior, making traditional detection methods less effective. AI‑generated bots can bypass captchas, scrape content, and launch credential‑stuffing attacks at scale.

  • Credential stuffing and account takeover attempts
  • Content scraping and SEO manipulation
  • Distributed denial‑of‑service attacks using AI‑orchestrated botnets
  • Fraudulent ad clicks that drain advertising budgets

Blackwall’s expanded toolset

The new funding will fund enhancements to Blackwall’s AI‑driven threat intelligence engine, real‑time traffic analysis, and automated mitigation controls that can be deployed directly within hosting environments.

Customers will also gain access to a dashboard that visualizes bot traffic patterns, offers actionable alerts, and integrates with existing security information and event management (SIEM) solutions.
