Defence contracts with ABDO accreditation
Handling classified defence information without a structured security system is a liability you can't afford.
Tidal makes ABDO compliance straightforward. Implement all required security measures for defence contracts, manage classified materials with confidence, and pass Ministry of Defence audits with proven compliance evidence.
ABDO in depth
ABDO stands for Algemene Beveiligingseisen voor Defensieopdrachten, the security requirements the Dutch Ministry of Defence places on suppliers executing a contract that involves classified information. They cover organisation and management, the reliability of personnel, physical security, and cybersecurity.
In practice ABDO is often read as paperwork for the tender. That misses the point, because the requirements reach into who you hire, how your buildings are secured, and which systems may touch classified material, and the security investigation looks at all of it.
By treating ABDO as a security baseline rather than a bid document, clarity emerges. Every requirement has an owner, an implementation status, and evidence behind it, so an investigation finds a current picture instead of a reconstruction.

Frequently asked questions
ABDO (Algemene Beveiligingseisen voor Defensieopdrachten) defines security requirements for organisations working with the Dutch Ministry of Defence. If your organisation handles classified defence information or works on defence contracts, you likely need ABDO compliance. For new government contracts that carry risks to national security, the government has applied ABRO since 1 January 2026, which builds on the ABDO requirements and extends them across central government and the police.
