In today’s escalating cyber threat landscape, traditional backup strategies are insufficient to protect the most critical assets. Modern threat actors have evolved beyond simply encrypting operational systems to systematically targeting backup infrastructures, leaving organizations with no safety net for recovery. According to Rubrik Zero Lab’s “” report, 74% of organizations discovered their backup or recovery systems were at least partially compromised during attacks, with over a third (35%) suffering complete compromise. This trend underscores the critical need for cyber resilience strategies that specifically protect backup environments from sophisticated threats while enabling rapid recovery capabilities.

As organizations continue their digital transformation journeys, backup systems have become prime targets for attackers due to their value as the last line of defense. Most security frameworks fail to adequately safeguard these systems against ransomware and other sophisticated techniques. Threat actors exploit this oversight, using advanced methods to corrupt backup catalogs, encrypt backup data stores, and manipulate recovery environments, making restoration of operations nearly impossible after an attack. The consequences can be devastating: extended downtime, significant revenue losses, and reputational damage that can persist for years. For instance, IBM’s found that 70% of organizations experienced a significant or very significant disruption to business resulting from a breach, and only 12% reported that they had fully recovered. For those who were able to recover completely, more than three-quarters said it took them more than 100 days.

Adding to the complexity, Rubrik telemetry reveals that 27% of high-risk sensitive files contain critical digital data such as API keys, usernames, and account numbers—exactly the information threat actors seek to hijack identities and infiltrate systems. This protection gap demands a fundamental shift from traditional backup methodologies to zero-trust data security architectures that isolate backup environments, implement immutable storage, and provide continuous validation of recovery readiness.

Leading the way in backup security transformation

Forward-thinking organizations across industries are recognizing this critical vulnerability and taking decisive action to modernize their backup security posture. These companies are implementing comprehensive data protection strategies that go beyond traditional backup approaches, integrating advanced cyber resilience capabilities that can withstand sophisticated attacks while ensuring rapid recovery.

Arm: Protecting the foundation of modern computing

As the architect behind the world’s most pervasive compute platform, Arm understands that securing intellectual property is paramount to innovation. The company implemented robust data protection and governance measures through strategic partnerships, ensuring the technology that powers everything from edge devices to cloud infrastructure is safeguarded.

Avolta: Securing global travel retail and F&B operations

The world’s leading global travel retail and F&B player embarked on an ambitious digital transformation to modernize legacy systems and strengthen cyber resilience. Avolta implemented comprehensive SaaS data protection featuring logical airgap, immutability, and rapid data restoration capabilities. This transformation ensures business continuity for their 20,000+ collaborating corporate users while providing the visibility and automation that reduces recovery times and provides the flexibility needed to quickly deploy new business initiatives across their global operations.

PACCAR: Building resilience for commercial vehicle innovation

This global technology leader that designs and manufactures trucks, and provides financial services and information technology, selected advanced data protection as their worldwide standard to support growth across four continents. PACCAR’s implementation focuses on identifying clean recovery points and establishing effective cyber attack response mechanisms. This resilient foundation allows the company to concentrate on core strategic initiatives, including modernizing security operations and advancing next-generation vehicle technologies.

Zurich North America: Regulatory compliance meets cyber resilience

With 150 years of risk management experience, Zurich North America moved proactively to improve capabilities and address the New York State Department of Financial Services Cybersecurity Regulation guidance by replacing complex legacy systems with cutting-edge data security technology. Their transformation includes automated ransomware investigation, immutable backups, logical airgap protection, and rapid recovery across hybrid cloud environments. This modernization strengthened cyber resilience while reducing legacy infrastructure complexity and accelerating innovation in the cloud-first economy.

Domino’s Pizza: Protecting every slice of digital operations

Recognizing technology’s critical role throughout their business operations, Domino’s proactively implemented robust immutable data protection and accelerated recovery capabilities. Their strategic approach ensures rapid threat response, minimal downtime, and secure global operations that protect thousands of franchisees and team members who depend on uninterrupted systems for daily operations.

The path forward for CIOs

These organizations demonstrate that proactive backup security transformation is not just possible but essential for maintaining competitive advantage in today’s threat landscape. For CIOs and security leaders, the message is clear: backup systems can no longer be treated as passive repositories but must be architected as active components of a comprehensive cyber defense strategy. The cost of inaction—measured in downtime, recovery expenses, and reputational damage—far exceeds the investment required to implement modern, resilient backup security frameworks.

The evolution from traditional backup to cyber-resilient data protection represents a fundamental shift in how organizations approach business continuity. Those who act decisively today will be positioned to weather tomorrow’s increasingly sophisticated cyber threats while maintaining the operational agility needed for continued growth and innovation.
