CoreView adds new tools for secure Microsoft 365 tenants

CoreView has launched two products focused on security and operational risk at the Microsoft 365 tenant level, adding Tenant Resilience and a separate Tenant Management offering to its platform.

The company said it is responding to a rise in tenant-level attacks and configuration risks in Microsoft 365 environments. It cited a figure that 63% of Microsoft 365 tenants fail to enforce least-privilege access. It also referenced Microsoft reporting an increase in configuration tampering across identity and device management services.

CoreView positioned the two products for different teams. It said Tenant Resilience targets security teams responsible for tenant protection and recovery. It said Tenant Management targets operational teams responsible for governance and administration.

The products sit within the CoreView platform. CoreView said the offerings address configuration risk, excessive administrative privilege, and operational strain during security incidents and recovery work.

Microsoft 365 tenants hold configuration settings and access controls that shape how services behave. Large organisations also run multiple tenants, delegated administration models, and extensive identity policies. This expands the number of settings that administrators need to manage and audit.

"Many organisations believe their Microsoft 365 environment is protected until a single configuration change or over-privileged account breaks that assumption," said Andrea Sivieri, Chief Product Officer, CoreView. "Microsoft 365 has become critical infrastructure, yet configuration drift and unchecked access rights still undermine tenant security far more often than people realise. Taking deliberate control of configuration and privilege allows organisations to protect the tenant itself and operate Microsoft 365 safely at scale, even as complexity grows."

Tenant Resilience

CoreView said Tenant Resilience focuses on preparation, incident response, and recovery from tenant-level incidents. It said traditional SaaS security tools do not address these issues.

The company said the product reduces the impact of compromised privileged accounts. It does this by limiting excessive administrative access.

CoreView said the product detects unauthorised configuration changes and flags changes it considers high-risk. It said these changes can weaken security controls.

The company also said Tenant Resilience restores trusted tenant configurations after incidents. It described this as part of a recovery process.

CoreView said the product maintains operational continuity during attacks, audits, and large-scale changes. It linked that to periods where teams work under pressure and need to validate tenant settings quickly.

Tenant Management

CoreView launched Tenant Management as a separate product alongside Tenant Resilience. It described the product as the operational foundation for teams that govern Microsoft 365 environments at scale.

CoreView said Tenant Management automates routine governance and administrative controls. It said this reduces operational strain and human error as Microsoft 365 environments become more complex.

The company said organisations with large, complex, or multi-tenant Microsoft environments can use the product for visibility and control across users, licences, and delegated administration.

CoreView also said the product reduces operational complexity that slows response during incidents. It said complexity can increase risk.

CoreView said Tenant Management enforces consistent governance across distributed environments and rapidly changing environments. It said the product supports secure day-to-day operations. It also said it does not require organisations to expand administrative exposure.

CoreView said the launch reflects a broader reassessment of how organisations protect Microsoft 365 tenants themselves, rather than focusing only on individual workloads and user accounts. It framed tenant configuration and privilege management as key factors in preventing incidents and in making recovery more reliable.

The products are available through the CoreView One platform and the wider CoreView platform, according to the company.
