BitNinja is a server security platform designed for web hosting providers, VPS providers, and small businesses. The company offers a multi-layered, AI-powered security solution that protects web servers and hosted websites from a broad range of cyber threats through a centralized management console. The platform operates on a collective defense model called the "Defense Network," in which attack data gathered from all participating servers is shared across the community. This allows the system to continuously learn from new threats and apply those learnings to protect all connected servers proactively, before attacks reach individual infrastructure. BitNinja's core product modules include: an Anti-Malware scanner, a Web Application Firewall (WAF), Real-Time IP Reputation management, Outbound Spam Detection, and SiteProtection. These components work together to address threats such as malware infections, exploit attempts, malicious bots, phishing files, and spam originating from compromised accounts. The platform targets shared web hosting environments, VPS providers, and small businesses, offering tiered pricing and a reseller partner program. It integrates with common hosting stacks and is managed through a single console, reducing the need for per-server individual configuration. Prior to BitNinja, hosting providers in its case studies relied on tools such as ModSecurity, ClamAV, and Patchman. BitNinja is SOC 2 certified and compliant with GDPR and CCPA regulations. The company is headquartered in Hungary and operates as BitNinja Technologies Zrt.
