Overview: Anchoring Cyber Resilience in a Cloud-First World​

The landscape of digital operations has shifted dramatically in recent years, with organisations heavily reliant on cloud services such as Microsoft 365 for day-to-day business. This reliance has introduced new dimensions of risk—ransomware campaigns, account takeovers, and targeted data destruction now strike at the heart of productivity and business continuity.
Sophos and Rubrik are directly addressing these vulnerabilities by delivering a fusion of prevention, detection, and recovery capabilities within one unified platform. The new offering empowers enterprises to not only block sophisticated attacks, but also to recover quickly when cyber defenses are inevitably breached.

The Partnership: Blending Prevention and Unmatched Recovery​

Why This Collaboration Matters​

Modern cyberattacks frequently circumvent existing defenses, leaving businesses exposed to devastating data loss and lengthy downtimes. While Sophos brings its renowned prevention-first philosophy—leveraging AI, deep learning, and Security Operations Center (SOC)-level Managed Detection and Response—Rubrik delivers the industry's leading SaaS-based protection with rapid, reliable recovery functionality.
Key aspects of the offering include:

• Unified Security Management: The solution is delivered natively within Sophos Central, enabling streamlined management of security and backup operations.
• MDR-Optimised: It is the first backup platform to integrate with an MDR workflow, ensuring anomalous events trigger both threat response and automated backup checks.
• Global Reach: With over 75,000 Sophos MDR and XDR customers worldwide, the impact and reach of this integration are immediate and substantial.

Addressing an Evolving Threat Landscape​

The Ransomware and Account Compromise Crisis​

Numerous industry reports, including Sophos’ annual State of Ransomware survey, demonstrate that while ransomware remains rampant, a troubling portion of organisations still pay hefty ransoms, only to discover backups are either missing, inoperable, or tampered with. Furthermore, account takeovers now plague 60% of Microsoft 365 tenants, while incidents of email compromise have reached a staggering 81%. Attackers are also adept at manipulating data retention settings and permanently deleting essential business information if global admin credentials are breached.
The gap between prevention and recovery represents a core weakness in many cyber resilience strategies. Sophos and Rubrik’s joint solution bridges this chasm by bundling airtight backup controls with vigilant security monitoring, ensuring both proactive defense and reactive confidence.

Core Features: What Sets This Solution Apart​

Secure, Immutable Backups​

At the heart of resilience is the immutability and integrity of data backups. Rubrik brings industry-leading controls:

• Air-Gapped Storage: Backups are physically isolated from production data, making them unreachable from compromised environments.
• WORM Locks: “Write Once, Read Many” technology ensures backup data cannot be altered or deleted before designated retention periods expire.
• Customer-Held Encryption Keys: Customers retain full control over encryption, adding an essential layer of privacy and ownership.
• Data Lock and Multifactor Authentication: Even in the scenario of admin credential compromise, backup tampering is prevented through strict authentication requirements.

Fast, Flexible Recovery Across Microsoft 365 Workloads​

The solution extends rapid point-in-time or granular recovery options for:

• Exchange email accounts
• OneDrive files and entire drives
• SharePoint sites
• Teams channels and conversations

Restores can target both active and inactive user accounts, enabling precise data reconstruction after accidental deletion or targeted sabotage.

Automated Protection and Discovery​

• Entra ID-Based Policies: Rubrik automatically enforces policies based on user and group identities synced from Microsoft Entra ID (formerly Azure Active Directory).
• Delegated Administration: Distributed IT environments benefit from flexible, role-based controls.
• Continuous Auto-Discovery: All Microsoft 365 users, sites, and mailboxes are identified and protected with minimal manual intervention, reducing touchpoints and risk for human error.

Unified Platform Experience​

Unlike bolt-on or siloed solutions, this partnership delivers all protection, monitoring, and response workflows through Sophos Central. This platform already synthesizes insights from over 350 telemetry sources—across endpoint, cloud, identity, email, network, and business applications—making integration seamless and intuitive.

AI-Powered Threat Detection and Response Synergy​

Sophos Central’s integration of deep learning and Large Language Models (LLMs) within its detection fabric enables rapid identification of suspicious activity anywhere on the Microsoft 365 attack surface. With Rubrik’s backup telemetry now fully in the loop, security teams benefit from:

• Correlated Alerts: MDR analysts can cross-reference behavioral anomalies with recent backup snapshots, helping determine impact and best recovery points.
• Automated Incident Containment: When advanced threats are detected, workflows can quarantine affected assets and trigger restoration protocols autonomously.
• Continuous Coverage: The MDR-optimised backup architecture ensures that business-critical data remains protected, regardless of how threat tactics evolve.

Bringing Efficiency and Confidence to Security Operations​

Streamlined Workflows for Security and IT Teams​

In today’s overburdened IT landscapes, the ability to unify tools and reduce operational drag is game-changing. By anchoring both risk prevention and data recovery in a single dashboard, organisations benefit from:

• Less Complexity: Fewer disparate tools to learn, monitor, and maintain.
• Faster Recovery: Consolidated incident response reduces the time from breach discovery to business resumption.
• Holistic Visibility: Integrated dashboards span both security events and backup health, empowering better risk-informed decision-making.

Simplified Compliance and Audit Readiness​

The new solution includes robust auditing with immutable logs and chain of custody records for backups, easing compliance with regulatory standards such as GDPR, HIPAA, and SOX. Role-based access keeps sensitive backup operations segmented, and granular reporting supports rapid response to audit requests or legal holds.

Risks, Limitations, and Critical Considerations​

Potential Weaknesses and Points of Caution​

While the combined power of Sophos and Rubrik significantly elevates Microsoft 365 resilience, organisations should be mindful of several considerations:

• Cloud Dependency: As with any SaaS-based solution, connectivity to the platform is a prerequisite for both protection and recovery operations. Critical infrastructure outages could introduce bottlenecks.
• Scope of Protection: While coverage for Microsoft 365 workloads is deep, backup and recovery for on-premises or broader multi-cloud environments may need supplemental solutions.
• User Training: New integrations—especially those that touch multiple business units—require effective rollout strategies and staff education to avoid operational missteps or configuration drift.
• Resilience is Not Absolute: No solution is foolproof, especially in the face of insider threats that may have broad administrative access. Proactive testing of backup recoverability should be scheduled regularly.
