Cybonet

Cybonet is an Israeli email and network security vendor headquartered in Haifa, originally established as PineApp in 2000-2002 before rebranding to Cybonet. Its flagship products, Mail Secure and Outbound Spam Guard, provide gateway-level email security — anti-phishing, anti-spam, sandboxing, and outbound data-loss protection — aimed at small and mid-sized businesses that cannot run a full enterprise security stack.

Beyond email, Cybonet sells CyBoWall, a lighter-weight network security and monitoring appliance intended to give SMBs visibility into internal network threats without the complexity of enterprise SIEM/NDR platforms. The company has long positioned itself around channel distribution, selling primarily through resellers and managed service providers rather than direct enterprise sales.

Cybonet’s story is one of longevity in a narrow niche rather than rapid innovation: the company claims installations across roughly 3,000 systems and tens of thousands of protected domains in 60 countries, built up over two decades, but it has not disclosed recent funding, and independent, current usage data is difficult to verify. It competes against much larger, VC-backed email security players (Proofpoint, Mimecast, Abnormal Security) with far greater R&D investment in AI-driven detection.
