‍They log in and reconfigure your Microsoft 365 tenant.

CoreView hardens your configurations, catches any drift, and rewinds to a known good state - for your identities, your endpoints, and the AI agents running inside your tenant - in minutes.

The 5 pillars of Microsoft 365 tenant resilience

Harden your tenant against attacks

You wouldn’t deploy a server without hardening it. Why is Microsoft 365 any different?

Align Tenant Configurations with CIS standard

Detect & remediate where tenant configurations aren’t aligned with the CIS M365 configuration baseline.

Detect dangerous exposure points

Detect & remediate guest users in sensitive areas, external sharing, apps with external access, and admins with mailboxes.

Continually enforce rigorous identity security

Constant detection & remediation of users with weak passwords, no MFA, and no conditional access policy.

Segment tenants, remove privilege

Don’t just manage privilege. Remove it

Create virtual tenant segments

Partition your tenant into virtual segments, each serving as an administrative boundary, to reduce your attack surface.

Grant “just enough” access

Give admins “just enough” access to complete their work within a given virtual tenant segment.

Deprovision dangerous M365 privileged accounts

Eliminate unnecessary privileges from admin accounts that are the prime targets for attackers.

Detect configuration tampering attacks

Attackers know you can’t detect configuration tampering in Microsoft 365. That’s why it’s their chosen attack technique.

Get alerted instantly and roll back rapidly

Get alerted instantly an unauthorized change occurs and roll back to your desired configuration state in minutes.

Audit every change

Get a detailed forensic audit trail showing when a configuration setting has been added, removed or changed.

Stop advanced Entra App attacks

Automatically detect when a privileged Entra app is created, consented, or granted risky permissions.

Explore the platform

Backup and restore tenant configurations

Rapidly recover your tenant configuration and audit precisely what happened

Rewind to your “golden image”

Automatically rewind back to your “golden image” Microsoft 365 tenant configuration and save weeks of manual reconfiguration.

Trace the attack's root cause

Pinpoint exactly who, when, and what changed, so you can trace the attack’s root cause and propagation.

Assess your security posture post-breach

Use CoreView's security score to assess the tenant against best practices, known threats, and compliance benchmarks.

Continually build operational resilience

Automate security operations, drive down operational costs and increase efficiency

Automate processes and drive efficiencies

Rapidly build and deploy automated workflows using 150+ “out of the box” automation actions (no code required).

Reduce ticket escalations

Delegate "just enough" access to IT admins – so they can self-serve administration in M365 rather than raising tickets.

Optimize license usage

Eliminate old, excessive, or inappropriate Microsoft licenses to reduce the attack surface and control costs.
