Digital security is the foundation of legal integrity

Is your law firm really protected against cyberattacks?

Legal data in the crosshairs of cybercriminals

Ransomware attacks on law firms and tax consulting firms are rapidly on the rise

Law firms, notary offices, and tax consulting firms handle highly sensitive and business-critical data on a daily basis, which is increasingly becoming the target of ransomware attacks—which is why active protection of digital infrastructure, tamper-proof backups, and early attack detection are crucial to preventing data loss and system failures.

Data Encryption, Operational Downtime, Loss of Trust

Law firms, notary offices, and tax consulting firms are increasingly becoming targets of cyberattacks, as they handle highly sensitive client files, contracts, and documents digitally on a daily basis. A successful attack can encrypt data, disrupt operations entirely, and cause lasting damage to client trust. The consequences range from delayed proceedings to significant reputational damage and financial risks. That is why it is crucial not only to store sensitive data but also to protect it with tamper-proof systems, prevent unauthorized access, and ensure reliable recovery in the event of an emergency.

Did you know?

  • Since 2018, at least 138 law firms worldwide have fallen victim to public ransomware attacks
  • Over 2.9 million records from legal institutions were affected
  • Attacks often lead to business interruptions and financial losses
  • Small and medium-sized law firms are also increasingly being targeted by cybercriminals
  • Tamper-proof backups are crucial for rapid recovery and protection

Between Data Protection Obligations and Cyber Threats

The Biggest Challenges

The increasing pace of digitalization makes the protection of sensitive client and document data a key challenge for law firms, notary offices, and tax consulting firms—especially in light of growing cyber threats, strict legal requirements, and limited IT resources.

Confidential Data in the Crosshairs of Cyberattacks

Legal firms handle information that requires special protection—from client files and legal documents to confidential contracts. This data is extremely attractive to cybercriminals. Protecting these digital assets requires a comprehensive security strategy that also includes backups and archives.

Inadequately Protected Data Backups

Many law firms and notary offices create regular backup copies, but these are often not tamper-proof. Modern ransomware targets backup systems to make recovery impossible. Only backups with access controls and WORM technology offer protection against data loss and extortion.

Strict Data Protection Requirements

The GDPR, the BRAO, and the BNotO require law firms, notary offices, and tax consulting firms to protect personal and legally binding data against tampering, loss, and unauthorized access. Violations result in fines and professional disciplinary consequences.

Complex IT environments and limited resources

Small and medium-sized law firms, in particular, often have limited IT resources. Security solutions must therefore be easy to integrate, low-maintenance, and automated—to protect workflows without disrupting firm operations or notarization processes.

Prevention rather than reaction

Blocky for Veeam® protects backup data against tampering

Blocky protects your backup environment from ransomware

Effective protection against ransomware starts with data backup. Especially in law firms and tax consulting practices, where confidential client documents, deeds, and contracts are processed daily, the security of backup systems is crucial. Blocky for Veeam® monitors every write and delete operation and allows the backup software itself to make changes. This ensures that your backups remain unchanged, tamper-proof, and recoverable at any time.

Reliable Tamper Protection

  • With WORM (Write Once – Read Many) technology, your backup files are stored in a way that prevents them from being altered after they are written.
  • The fingerprinting process ensures that only authorized applications—such as Veeam—can access the data.
  • Any unauthorized attempt to write to or delete the data is consistently blocked and prevented in real time.

FAQ: 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 restores access after a ransom is 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?
