Sophos, in a strategic partnership with Rubrik, has unveiled a Microsoft 365 backup and recovery solution designed to render ransomware attacks futile by combining immutable, air-gapped backups with deep integration into Managed Detection and Response (MDR) workflows. Dubbed Sophos M365 Backup and Recovery Powered by Rubrik, it is the first data protection product purpose-built for MDR environments and natively embedded within the Sophos Central security operations platform. Available in the coming months, this SaaS-based offering marks a significant leap in closing critical resilience gaps for organizations besieged by escalating attacks on Microsoft 365 tenants.

The Escalating Threat Against Microsoft 365

Microsoft 365 has become the digital backbone for millions of businesses, but its ubiquity has transformed it into a prime target for cybercriminals. Research cited by Sophos paints a grim picture: 60% of Microsoft 365 tenants have experienced account takeover attempts, while 81% report incidents of email compromise within the past year. Attackers who seize global admin credentials can wreak irreversible havoc—deleting backups, manipulating retention policies, or purging sensitive data before victims realize the breach.

Despite native security features, data loss from ransomware, insider threats, or accidental deletion remains a persistent risk. Sophos' own State of Ransomware report underscores the vulnerability: nearly half of ransomware victims ultimately pay the ransom, and only 54% manage to restore data solely from backups. Traditional backup solutions often lack the isolation and integration required to withstand sophisticated adversaries who now actively target backup infrastructure.

A Union of Prevention and Recovery

Sophos, a frontrunner in MDR and endpoint security, and Rubrik, a pioneer in immutable cloud data protection, have joined forces to address this crisis. “We are reshaping what it means to stay operational in a world shaped by constant digital disruption,” said Joe Levy, CEO of Sophos. “This is the future of cyber resilience: an intelligent, adaptive partnership that ensures organizations remain secure, responsive, and uninterrupted.”

Rubrik CEO Bipul Sinha added, “Today’s cyber threat landscape demands more than just robust prevention—it requires fast, reliable recovery when prevention fails. We’re proud to support Sophos in delivering critical cyber resilience capabilities directly within a platform security teams know and trust.” The result is a unified, SaaS-delivered solution that fuses threat prevention, detection, and guaranteed recovery into a single interface.

Core Capabilities: Immutable, Automated, and Rapid

Secure, Immutable Backups

At the heart of the solution lies an air-gapped architecture from Rubrik. Backups are stored in an isolated environment completely separate from the production Microsoft 365 tenant, rendering them inaccessible to ransomware. The defense is fortified by:

  • WORM (Write Once, Read Many) locks – Data cannot be overwritten or modified for a preset time, blocking even malicious insiders or attackers with admin privileges.
  • Customer-held encryption keys – Only end-user organizations retain the keys, ensuring data privacy and preventing unauthorized restores or deletions.

Even if an attacker compromises Microsoft 365 admin credentials, the backup remains tamper-proof.

Fast, Flexible Recovery

Speed is paramount during a crisis. The solution enables rapid, granular restoration across all major Microsoft 365 services:

  • Entire mailboxes, individual emails, OneDrive accounts, SharePoint sites, and Teams channels can be restored to original or alternate accounts.
  • Support for recovery to inactive or deleted accounts proves critical when responding to account takeovers or insider sabotage.
  • Granular, surgical recovery minimizes downtime and prevents the cascading impact of data loss.

Automated Protection

Manual configuration is minimized through intelligent automation:

  • Auto-discovery of new mailboxes, users, sites, and Teams ensures complete coverage without constant manual effort.
  • Entra ID-based policy enforcement dynamically applies security and retention policies as users onboard, offboard, or change roles.
  • Delegated admin roles provide granular control, vital for organizations with distributed IT teams or regulatory requirements.

Unified Experience in Sophos Central

By embedding backup management directly into Sophos Central, the solution eliminates tool sprawl and operational friction. Security teams gain a single pane of glass for managing protection and recovery across endpoints, networks, identity, cloud applications, and now Microsoft 365 data. The platform ingests telemetry from over 350 sources—including endpoint, network, cloud, and email—feeding advanced AI models that correlate threats across the entire attack surface. When a threat is detected, workflows can automatically trigger backup verification or initiate recovery actions, closing the cyber resilience loop.

Real-World Impact: Closing the Resilience Gap

The partnership directly addresses the most dangerous vulnerability in modern cyber defenses: the assumption that native Microsoft retention equals bulletproof backup. Attackers who compromise admin accounts often delete or modify backup policies, leaving organizations with no path to recovery. Sophos M365 Backup and Recovery ensures that even in worst-case scenarios, data remains restorable.

For the 75,000-plus Sophos MDR and XDR customers worldwide, the integration promises a seismic reduction in operational complexity. Instead of juggling disparate tools, teams can act faster with unified visibility and automated response. The solution also positions MSPs and MSSPs to deliver enterprise-grade cyber resilience to their customers without heavy infrastructure investment.

Advanced Technology Under the Hood

AI-Driven Threat Analytics

Sophos Central leverages custom large language models (LLMs) and frontier AI models to parse massive data streams across devices, users, and cloud applications. These models detect novel attack techniques and malicious behavior far faster than manual review. When a suspicious activity—such as a user suddenly downloading thousands of emails—is flagged, the system can immediately verify backup integrity and, if needed, initiate restoration.

350+ Telemetry Sources

Signals from endpoints, network appliances, cloud workloads, email accounts, and business apps fuel cross-domain threat correlation. This holistic visibility enables context-aware response: an endpoint compromise can automatically isolate the affected account and trigger a backup restore, all from the same console.

SaaS-Native Simplicity

Being entirely SaaS-delivered removes the burden of on-premises hardware or software installation. The solution remains perpetually updated with the latest security controls, AI models, and backup innovations. Deployment is rapid and scales effortlessly from small businesses to global enterprises.
