FirmBrowser vs SURF Zero Trust Enterprise Browser

FirmBrowser has no write-up on Specifiction yet; its figures are above.

SURF Zero Trust Enterprise Browser is a browser and extension for organisations that enforce security controls on user devices. It can discover AI tools, mask sensitive prompts, and block risky uploads in real time. A sandboxed, human-verified runtime is described for autonomous browser agents, with an air gap between planning and live access. Scoped access to corporate applications is available for contractors, BYOD staff, and acquired teams without VPN or VDI. SURF says it logs AI interactions and policy decisions while keeping personal browsing private. Controls map to GDPR, ISO 27001, SOC 2, and DORA, with SOC 2-ready evidence generation. Deployment can use existing MDM or self-installation, and enforcement runs on the device without proxy or cloud redirection. The full browser supports Windows, macOS, and Linux; mobile support includes iOS, iPadOS, and Android. The extension works with Chrome, Edge, and other Chromium browsers. Integrations include Okta, Microsoft, Splunk, Datadog, Kandji, HashiCorp, VirusTotal, and Elastic.
