Free IT Tools & Security Assessments
Use our free tools to scan your domain, benchmark website and email hygiene, estimate downtime cost, and sharpen phishing instincts. Most utilities run without an account, and the password checker does not submit password values to NHM.
The security dashboard and saved monitoring require a free NHM account so results stay tied to your organization. Upgraded plans add continuous checks, history, and alerts—see plans for detail.
How to get the most from these tools
- Start with Domain Checkup or IT Checkup to establish a baseline you can share with leadership or your IT partner.
- Run the Security Survey quarterly and track whether policies, backups, and access controls are improving.
- Use the Phishing Quiz in team meetings—short, memorable practice beats a once-a-year training video.
- When you are ready for ongoing monitoring and alerting, pair an account with the DomainGuard mobile app for notifications on the go.
