The legacy approach to Microsoft security isn’t fit for purpose

Microsoft 365 is not an app, it’s 55+ interconnected apps & services under relentless attack. Legacy security tools can't keep up. With no visibility of configurations, tenant wide privileges by default, and no tenant configuration backup, it’s time for a new approach.

That’s why organizations choose CoreView

Harden your tenant, remove the toys attackers use to reach their end goal, and restore your tenant configurations after an incident.  

As recommended by microsoft:
“By deploying CoreView, enterprises gain robust tenant resilience and compliance solutions that strengthen their security posture.”

Master Microsoft 365 Tenant Resilience with CoreView

Harden the tenant to defend against attacks 

Harden your m365 tenant, just as you would any server

Tenants that don’t comply with standard security baselines and best practices are an easy target for attackers.

CoreView detects & remediates where tenant configurations aren’t aligned with the CIS M365 configuration baselines. Identify dangerous exposures such as guest users in sensitive areas, external sharing, apps with external access, and admins with mailboxes and continually enforce rigorous identity security, including weak passwords, no MFA, and no conditional access policy.

Segment tenants, remove privilege

Don’t just manage privilege. Remove it.

Microsoft 365 privileged accounts have tenant-wide powers, meaning you’re always only one privileged account compromise away from total tenant takeover.

CoreView partitions your tenant into virtual segments, each serving as an administrative boundary, so you can give admins “just enough” access to complete their work within a virtual tenant segment and deprovision the dangerous M365 privileged accounts that attacker target.

Detect M365 configuration tampering attacks 

Attackers know you can’t detect configuration tampering

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

CoreView alerts you instantly an unauthorized configuration change occurs so you can roll back to your desired configuration state in minutes. Get a detailed forensic audit trail showing when a configuration has been added, removed or changed.

Recover your tenant and audit

Rapidly recover your tenant configuration and audit​ precisely what happened

When disaster strikes, restoring user data isn't enough - you need your environment working. CoreView enables you to automatically rewind back to your “golden image” of the Microsoft 365 tenant configuration, saving weeks of manual reconfiguration. Analyze the attack, pinpointing exactly who, when, and what changed, so you can trace the attack’s root cause and propagation.

Build operational resilience

Automate operations, drive down costs and increase efficiency

The Microsoft 365 attack surface is complex and ever-expanding. Use CoreView to manage the complexity by building and deploying  automated workflows using 50+ “out of the box” automation actions (no code required).  

Reduce ticket escalations by delegating "just enough" access to IT admins – so they can self-serve administration in M365 rather than raising tickets.
