DomainGuard
Stop employees logging into SaaS with personal emails
Browser extension for IT admins that enforces corporate email domain policies on SaaS login pages. No SSL inspection, no traffic proxying — policy enforced directly in the browser. Deploys via Group Policy in minutes.
Hey Product Hunt! 👋
I built DomainGuard after seeing a problem that keeps coming up for IT teams: employees logging into Slack, Salesforce, Microsoft 365 and other SaaS tools with their personal Gmail or Hotmail accounts — creating shadow IT, compliance gaps, and data leakage risks.
The standard fix is tenant restrictions via a proxy, but that means SSL-inspecting all your company traffic. It's heavy, expensive, breaks things, and kills performance.
DomainGuard takes a different approach — the policy is enforced directly inside the browser. No traffic inspection, no proxy, no compatibility headaches. IT admins deploy it via Group Policy or the Chrome Web Store in minutes, set the allowed domains, and that's it.
Would love feedback from any sysadmins, IT managers, or security folks in the community especially if you've wrestled with this problem before. Happy to answer any questions!
