Olfeo Vision is a web security solution that implements Zero Trust Internet Access (ZTIA) technology to protect organizations from web-based threats. The solution operates on the principle of blocking access to unknown or uncategorized domains by default, only allowing users to access verified trusted sites. The platform utilizes a comprehensive URL database containing over 100 million URLs and 22 million domains, covering more than 99.5% of web requests in France and Europe. The database is maintained through a dual analysis approach combining artificial intelligence and human verification to ensure accurate categorization across 100 categories and 9 themes. Olfeo offers multiple deployment options including SSE (Security Service Edge) with SWG (Secure Web Gateway), DNS filtering, CASB (Cloud Access Security Broker) for SaaS application security, and on-premise solutions. The platform provides granular content analysis down to the subdomain level for blogs, e-commerce sites, and other web properties. The solution addresses the challenge of ephemeral malicious domains and zero-day threats by blocking uncategorized sites rather than relying solely on threat recognition. It includes features for filtering malicious domains, blocking malware and web-based attack vectors, and integrating with SIEM or XDR solutions through Log Connector. Olfeo also offers an awareness training component for cybersecurity education and provides white-label URL and SaaS application databases for OEM partners.
