Protecting Sensitive Data in the Healthcare Sector

Is your patient data safe from ransomware?

Why Hospitals need to take action

67% of healthcare facilities worldwide have been affected by ransomware attacks

Hospitals and healthcare facilities have also been targets of cybercriminals for years. Ransomware attacks, in particular, threaten the availability and integrity of sensitive patient data—with dramatic consequences for patient care.

 

Healthcare Data in the Crosshairs of Cybercriminals

Digital patient data is at the heart of modern hospitals, clinics, and laboratories. Without it, effective patient care would be virtually impossible: from emergency rooms and imaging procedures to medication and billing, nearly all processes are now digital. It is precisely this dependence that makes the healthcare sector a prime target for cybercriminals.

Did you know?

  • Ransomware attacks disrupt operations and thus jeopardize patient care
  • 67% of healthcare facilities were affected by ransomware attacks in 2023. This makes the healthcare sector one of the most vulnerable industries.
  • In 93% of ransomware attacks, backup repositories are specifically targeted to put pressure on hospitals.
Identifying and solving challenges

What to keep in mind

Modern backup infrastructures face significant challenges today, as they are increasingly becoming direct targets of complex cyberattacks.

Ransomware as the Greatest Threat

Attacks not only encrypt production systems but also specifically target backups. This makes recovery impossible.

Attacks on Windows-based backup servers

Since over 85% of ransomware attacks target Windows systems, Windows-based Veeam servers on NTFS or ReFS volumes are at risk.

Unauthorized Access and Compromised Security

Malware and unauthorized processes can manipulate or delete backup data—even security software can be targeted by attacks.

Complexity and Slow Recovery

Traditional offsite or cloud solutions are expensive, difficult to implement, and result in long recovery times in the event of an emergency.

The last line of defense

Blocky for Veeam® protects you when it counts

Protect Your Backup Environment

Blocky for Veeam® picks up right where other security measures leave off: with the backup data. While patient data and clinical applications—such as EHRs, PACS, or lab systems—may already be encrypted in the event of an emergency, Blocky prevents even the last line of defense—the backup—from being destroyed or tampered with.

For hospitals, this means that even if patient data or medical systems are encrypted, the Veeam backups remain intact.

When Backups Become Tamper-Proof

  • With WORM (Write Once, Read Many) technology, backup files are stored on NTFS or ReFS volumes in a way that prevents them from being modified after they are written.
  • Fingerprinting ensures that only authorized applications—such as Veeam—have access to the data.
  • Any unauthorized attempt to write to or delete the data is consistently blocked.
The benefits of FileLock

Healthcare Solutions

Our solution combines the highest level of security, regulatory compliance, and technological flexibility in a future-proof and cost-effective archiving platform.

Comprehensive protection for your data

Less Risk for Clinics

Blocky for Veeam®

By leveraging modern WORM technology, your backups are stored in a tamper-proof manner—directly on the Windows Veeam server. Integrated zero-trust write control ensures that only authorized processes are granted write access, while unauthorized access is consistently blocked. No additional hardware or separate Linux server is required. The solution can be installed in less than 30 minutes and seamlessly integrated into your existing environment.

Archive in a manner that complies with audit requirements

The Benefits of FileLock

FileLock

FileLock uses state-of-the-art WORM technology to ensure tamper-proof archiving of sensitive data, while complying with international standards and all legal requirements. It is designed to be hardware-independent and integrates seamlessly into existing systems. Additional compliance replication provides even greater security and protection against failure. At the same time, the solution remains cost-effective and offers a future-proof foundation for long-term data archiving.

Future-proof long-term archiving

Secure and Cost-Effective Archiving of Medical Data

XtreemStore

XtreemStore is based on open standards such as LTFS and TAR, ensuring long-term accessibility and future-proofing of your data. Thanks to modern interfaces such as S3/Glacier, HSM front-end, and REST API, the solution can be flexibly integrated into existing IT infrastructures. It is cost-effective, virtually unlimited in scalability, and particularly user-friendly thanks to an intuitive interface.

Air-gap protection, multi-tape copies, and replication ensure maximum data security, while 24/7 support from Germany and the optional MetadataHub extension provide additional value.

Everything You Need to Know

Here you’ll find answers to the most frequently asked questions about our solutions, products, and applications—from security and archiving to data management.

What is ransomware?

Ransomware is malware that encrypts or deletes data and only releases it after a ransom has been paid. As attacks become increasingly sophisticated and frequent, they pose a growing threat to businesses of all sizes and across all industries.

What are the consequences of a ransomware attack?

A ransomware attack can paralyze entire networks, prevent access to critical data, and result in high recovery and downtime costs. Even after paying the ransom, it is often impossible to fully recover the data.

How does ransomware get into my company?

Ransomware typically enters a company through phishing emails, infected attachments, or compromised websites. A single wrong click is enough to install malware unnoticed and exploit security vulnerabilities.

Why do I need Blocky?

Blocky is the ideal complement to Veeam® for effectively protecting your backup data against malware and ransomware attacks. This ensures that your backups remain intact and accessible even in the event of an emergency.

Which Windows operating systems are supported?

Blocky supports Windows Server 2012, 2016, 2019, 2022, and 2025.
