Critical Data Protection

Who We Are

At Obventum Cyber Security, we know that data is the lifeblood of modern organizations — from intellectual property and sensitive financial information to medical records and government communications. A single breach can result in devastating consequences: regulatory fines, reputational damage, operational downtime, and loss of client trust.

Our Critical Data Protection services have helped organizations across Croatia, the Netherlands, and Slovenia defend their most sensitive information assets. We work closely with government agencies, healthcare institutions, financial services, legal firms, and technology providers to ensure that data is not only stored securely but also protected against exfiltration, manipulation, or ransomware-driven extortion attempts.

Why Critical Data Protection Matters

Today’s cyber threats are increasingly data-focused. Attackers know that stealing, encrypting, or leaking data provides the greatest leverage for ransom and disruption.

Key challenges include:

• Ransomware targeting sensitive repositories in hospitals and government systems.
• Cloud misconfigurations leaving sensitive data buckets exposed to the public.
• Weak insider access controls enabling privilege abuse.
• Lack of visibility into who is accessing, moving, or copying critical files.

Without a focused data protection strategy, organizations risk losing their most valuable assets in an instant.

Our Methodology

• Data Mapping & Classification
  We identify where your critical data lives — on-premise, in the cloud, or across hybrid environments — and classify it by business impact.
• Simulated Data Exfiltration Attacks
  Using red team techniques, we replicate how attackers attempt to extract sensitive information undetected. This validates whether Data Loss Prevention (DLP) and monitoring systems can actually stop real-world threats.
• Cloud Data Security Assessments
  We test popular cloud providers (Azure, AWS, Google Cloud) for misconfigurations, over-permissive roles, and shadow IT services that can leak confidential information.
• Insider Threat Simulation
  By testing access misuse scenarios, we expose what happens if an employee or contractor with legitimate credentials decides to abuse their access.
• Encryption & Storage Validation
  We validate whether sensitive files, backups, and communications are encrypted both at rest and in transit, following frameworks like ISO 27001, NIST CSF, and CIS Controls.

Client Impact Example

A major healthcare provider in the Netherlands approached Obventum after concerns that ransomware groups were increasingly targeting hospitals across Europe.

Our data protection assessment revealed:

• Patient records stored unencrypted on a shared server.
• Over 200 employees with unnecessary administrative access.
• Backup systems connected directly to the production environment — making them vulnerable to encryption during an attack.

By simulating a ransomware attack, we showed how attackers could steal and lock access to thousands of sensitive patient records within hours.

Following our recommendations, the client implemented segregated backups, least-privilege access, and enhanced encryption policies. Within 90 days, their resilience against ransomware-driven data theft had drastically improved.

Strengthening Data Security in Croatia, the Netherlands, and Slovenia

Obventum has partnered with government ministries in Croatia, financial institutions in Slovenia, and multinational corporations in the Netherlands to safeguard sensitive datasets. From intellectual property in tech firms to citizen data in government registers, our role is to shield what matters most.

We combine offensive security expertise with data governance best practices to ensure that critical information is resilient against evolving threats.

What Our Clients Say

“Obventum showed us exactly where we were exposed and helped us close the gaps before attackers could exploit them. Their offensive-first approach to data protection gave us the confidence to store and share sensitive information securely.”
