New! Dark Site Support for Immutable Backup Protection in Air-Gapped Environments

Organizations with the stringent security requirements can now use Arcserve cyber resilience solutions to create and protect immutable backups in completely isolated environments – no internet connection required.  Today’s release of dark site support for Arcserve Cyber Resilient Storage provides immutable data backups for environments that require offline backup and recovery practices.  

Organizations in highly secure industries like finance, healthcare, defense, and critical infrastructure face a challenging balancing act: implementing robust data resilience measures while maintaining strict isolation from external networks. These air-gapped "dark site" environments represent high levels of security – but have traditionally limited immutable backup and recovery options.

The latest release of Arcserve Cyber Resilient Storage now supports dark site deployments that have zero internet connectivity requirements.  

What Makes Dark Sites Essential for Security-Sensitive Organizations

Dark sites provide critical advantages for organizations handling sensitive data:

• Isolated Backup Environment: A clean, safe environment for data backup that remains untouched by ransomware or cyberattacks

• Accelerated Business Recovery: Pre-configured systems and data enable faster recovery with minimal downtime

• Protection Against Backup Tampering: Physical isolation keeps recovery data completely out of attackers' reach

• Operational Continuity: Ability to keep business functions continuing even during worst-case scenarios

• Compliance and Insurance Alignment: Adherence to increasingly stringent regulatory requirements and cyber insurance expectations 

Key Dark Site Capabilities in Arcserve Cyber Resilient Storage

The latest Cyber Resilient Storage release for on-premises immutable backup storage introduces three essential capabilities for air-gapped environments. 

Offline Software Updates

Administrators can now manually install Cyber Resilient Storage product updates from a USB drive, eliminating requirements for internet connectivity. The local validation system (Cyber Resilient Storage installation process) verifies update package integrity and authenticity of the update package on the removable media, ensuring only authorized users can perform updates.

USB Export for Diagnostics

System diagnostics and support bundles can be exported from the Cyber Resilient Storage interface directly to USB storage for secure sharing with support teams. These exports include comprehensive logs, configurations, and system metadata—all protected with checksums to maintain data integrity.

Local Network Time Security (NTS) Server Support

Organizations can now configure Cyber Resilient Storage to use a customer-managed local NTS server for time synchronization during installation and ongoing operations, instead of relying on publicly available internet-based time servers. 

Business Benefits of Dark Site Support

Enhanced Security and Compliance

The newly added flexibility that allows to deploy Cyber Resilient Storage in environments with no internet connectivity reduces the attack surface and simplifies compliance audits—critical factors for organizations subject to stringent regulatory oversight.

Operational Continuity Without Compromise

Organizations can now maintain their Cyber Resilient Storage servers and receive full support—even in completely disconnected, air-gapped environments—so business operations continue without interruption.

Increased Trust

Dark site support meets the highest security expectations, builds trust for mission-critical deployments, and aligns with best practices in ransomware defense. 

Immutable Backup Protection—Now Available in Dark Site Environments

Arcserve Cyber Resilient Storage delivers robust protection against cyber threats through:

• True Storage Layer Immutability: Establishes backup copies that cannot be altered or deleted during defined retention periods

• Advanced Data Deduplication: Delivers up to 3:1 data reduction while maintaining performance and saving storage costs

• Granular Data Store Protection: Provides flexible immutability settings at the data store level

• Regulatory Compliance Alignment: Supports NIST, GDPR, HIPAA, and other frameworks with policy-driven security

With this latest release of Cyber Resilient Storage, immutable backups can be implemented in environments that are not connected to the internet, with offline support. Security requirements previously made deployment in such environments impossible.
