Build tenant resilience, master complex tenant management

The 5 pillars of Microsoft 365 tenant resilience

01Harden

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.

02Segment

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.

03Detect

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.

04Recover

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.

05Build

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.

Microsoft 365 security is a black box. This report is the flashlight.

You can't see inside your own tenant, and you don't know where it ends: how many settings, how many Entra apps, how many ways in. The 2026 State of Microsoft 365 Security Report lights it up. See where 279 IT and security leaders are actually exposed across identity, configuration, backup, and AI risk.
