The NIS2 Directive (EU Directive 2022/2555) strengthens cybersecurity requirements for essential and important entities across the EU. Among its key provisions, it introduces stricter obligations for incident reporting, audit readiness, and secure handling of sensitive data. Organizations must ensure that audit records, security logs, and incident reports are collected, stored, and accessed in a way that preserves their confidentiality, integrity, and availability.

When it comes to audit data management, NIS2 explicitly emphasizes:

• Data retention and protection – Audit records must be securely stored for the prescribed period and protected from unauthorized alteration or deletion.

• Access control – Only authorized personnel should have role-based access to audit information, with detailed logging of every access attempt.

• Segregation of sensitive information – Audit data should be logically or physically separated to prevent cross-contamination between systems or customers.

• Tamper-proof storage – Audit logs must be immutable, ensuring their validity in case of regulatory inspections or forensic investigations.

Our solution is a standalone server appliance with military-grade encryption that directly supports these requirements. By physically isolating the audit data environment, it eliminates exposure to shared or cloud-hosted risks. Quantum-proof encryption ensures that even if the physical media is compromised, the data remains unreadable without proper keys. Hardware-based encryption modules and secure key storage prevent unauthorized decryption, while built-in role-based access control enforces strict compliance with NIS2’s principles.

Beyond secure storage, the appliance is also a comprehensive platform for cybersecurity professionals to manage security controls across their organization’s networks and information systems, operate an information security management system, and support various audits. A core focus is integrating each EU Member State’s local NIS2 implementation into a unified operational framework, enabling multinational compliance without fragmented processes. Additionally, its AI-powered audit evidence evaluation and classification significantly reduces the human resource burden of audits, shortens audit timelines, and ensures a consistent, high-accuracy review process.

This combined approach guarantees compliance with NIS2’s secure storage, access control, and operational requirements while providing regulators and stakeholders with confidence that the audit trail is both authentic and protected against insider and outsider threats.
