Spirex Secure Enterprise Browser is a Chromium fork for enterprise use on web and Windows. It combines policy controls, data-loss prevention, DNS threat filtering, and zero-trust network access. Identity-aware, per-application access can be enforced without endpoint agents, VPNs, or proxies. Page sensors inspect redirects, suspicious overlays and iframes, hidden fields, risky active content, and browser-side injection patterns. The browser also detects brand-domain mismatches, deceptive sign-in prompts, and credential capture on other domains. Controls include screenshot protection, download blocking, and risk-triggered watermarks for sensitive uploads. Policies consider identity, application, source and destination context, and live page risk. A connector brokers approved private-application access from a datacenter or cloud VPC without inbound ports. Okta, Entra ID, and Google Workspace are listed integrations. Trials require application review for teams of 50 or more.
