What it does
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.
Enforce corporate email domain policies across your entire browser fleet. Deploy in minutes via Intune or Group Policy.
DomainGuard enforces corporate email domain policies across your entire browser fleet. Deploy in minutes via Intune or Group Policy — no user action required. No complex configuration. No end-user training. Just deploy and go. Create your organisation, define which email domains are allowed on which sites. Takes less than 5 minutes. Push the extension silently to all managed machines using your existing MDM. Users don't need to do anything. The extension detects login forms, enforces domain rules, blocks social logins, and logs every event. When an employee visits a login page, DomainGuard instantly checks the URL against your policies and guides them to use the correct corporate domain.…from domainguard.co

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
