A cybersecurity company hardens Microsoft 365 with Griffin31, and keeps it secure over time

A cybersecurity company with 200 users connected its Microsoft 365 tenant to Griffin31 in September 2025. Griffin31 showed the team which security settings were open and what mattered most, and the team hardened the tenant in order of priority. In seven months its security score more than doubled, and the daily check keeps the tenant secure.

The challenge

What we did together

  1. 1A clear picture from the first scan

    Griffin31 checked the tenant against more than 350 recommendations and showed what was open in each area.

    The benefit: One clear view of the security posture, instead of checking every setting by hand.

  2. 2Critical gaps first

    The team started with the critical gaps, the ones that open the door to account takeover, phishing and email impersonation, and closed them within weeks.

    The benefit: The most common ways to attack the tenant were closed first, and the rest went into an ordered work plan.

  3. 3Hardening across identity, email and devices

    Fixes in Entra ID, Exchange and Intune, following Griffin31’s recommendations.

    The benefit: Each area moves forward on its own, and the team sees exactly how far each one has come.

  4. 4Monitoring: every setting that slips back is flagged

    Griffin31 scans the tenant every day and flags settings that went back, so the team can restore them.

    The benefit: The hardening doesn’t wear down over time. A change shows up after the next scan, not months later.
