Blackwall is a cybersecurity company that builds AI-enabled web traffic management solutions, primarily its flagship product GateKeeper, a reverse proxy designed to mitigate malicious bots, L7 DDoS attacks, brute-force attempts, and automated threats.[1][2][4] It serves hosting service providers, managed service providers, and eCommerce platforms hosting SMB websites, solving the problem of underserved small and mid-sized businesses facing bot-driven threats that comprise up to half of web traffic by filtering malicious requests before they reach applications.[2][4] Blackwall demonstrates strong growth momentum, including a €45 million Series B raise in March 2025 and a rebrand from BotGuard to expand beyond bot mitigation into broader infrastructure protection.[2][3]
Founded in 2019, Blackwall partners with providers to scale security globally, optimizing infrastructure costs by 10-25% while enabling new revenue streams through high-value services.[2][4]
Blackwall was founded in 2019 by CEO Nikita (Nik) Rozenberg and CTO Denis (Dennis) Prochko, entrepreneurs with over 50 years of combined experience in cybersecurity, banking software, and other sectors.[2][3][5] Originally launched as BotGuard, the company emerged from the founders' expertise in addressing bot threats and web security at the hosting provider level, starting with a proprietary load balancing solution that integrated ad fraud protection and bot mitigation following a €12 million Series A round.[5]
A pivotal moment came with the 2025 rebrand to Blackwall, signaling an evolution to provide top-tier protection for SMBs via partnerships, expanding from bot-specific tools to comprehensive AI-driven traffic management amid rising cyber threats.[2] Early traction built on this model, positioning it for rapid scaling as seen in its recent €45 million Series B.[3]
Blackwall stands out in web security through engineering-focused features tailored for hosting ecosystems:
Blackwall rides the exploding bot threat trend, where bots constitute half or more of web traffic, amplified by AI-driven attacks, cybercrime, and reconnaissance in sectors like eCommerce, hosting, and SMB digital operations.[1][2][4] Timing is ideal amid 2025's cross-border intelligence surge and rising L7 attacks, with market forces like SMB digitization and hosting consolidation favoring its provider-partner model over direct-to-consumer sales.[2][3]
It influences the ecosystem by democratizing infrastructure protection—trusted by providers, it shields millions of sites, optimizes server density, and counters competitors like CHEQ, HUMAN, and Kasada by focusing on hosting-layer integration rather than end-user apps.[4][5] This strengthens the web's resilience, particularly for on-prem/cloud hybrids vulnerable to automated threats.
Blackwall's trajectory points to accelerated global expansion post-€45M Series B, deepening AI enhancements in GateKeeper for emerging threats like advanced scrapers and zero-day exploits while forging more provider partnerships.[2][3][4] Trends like AI-bot arms races, QUIC/HTTP3 adoption, and SMB cloud migrations will propel it, potentially evolving into a full-stack web infra leader influencing hosting standards.
As cyber dangers intensify, Blackwall's elite-yet-accessible shield positions it to safeguard the open web's foundation, turning bot chaos into secure growth for millions of sites.
BlackWall has raised $62.6M across 3 funding rounds. Most recently, it raised $49.0M Series B in March 2025.
