Security Clearance in the Navy: Naval Commandos, Vessels and Systems

Security Clearance in the Navy is a matter in which the details depend on the role, the information involved and the circumstances of each case. In the Navy, many roles are exposed to sensitive information: naval commando units, vessels, combat systems, naval intelligence and infrastructure. A person found security-unsuitable may lose an assignment or a track. This page explains the process and how to act when the clearance is disqualified.

Who Is Checked in the Navy

Those usually checked are candidates for special units and vessels, soldiers and officers in systems and intelligence roles, and career personnel moving up to a more sensitive role. In some roles, medical and psychological fitness that are separate from the clearance are also required.

What Is Checked and What May Cause Difficulty

The check usually examines the personal and family background, ties and affiliations abroad, criminal record and open cases, drug use, financial situation and debts, and online conduct. The level required is determined by the role, and in more sensitive roles the check is more comprehensive.

• Family or business ties abroad, especially in hostile countries
• A criminal record, an open case or a police record, even if closed
• Past or present drug use
• Debts, gambling or financial difficulties
• Inaccuracy or omission in the questionnaire, which is sometimes a more serious problem than the matter itself

What Happens When the Clearance Is Disqualified or Restricted

When the clearance is disqualified, the notice usually arrives in writing. It is worth clarifying immediately whether the decision covers only the specific role or all classified roles, and acting within the objection deadlines.

1. Request the reasons for the decision as far as they can be given.
2. Check the deadline for an objection and act within it, because the deadlines are short.
3. Prepare a written objection to the objection committee, with documents and explanations for every point that came up.
4. Check alternative assignments in parallel, so that you do not lose time in service.

The general details of the levels and the procedure appear in the guide security clearance in the IDF: levels and objection and in the guide the full guide to security clearance.

How I Represent in the Process

I handle security clearance and objections, and I previously worked as a lawyer in the Criminal-Administrative Department at the Shin Bet. I represent in preparation for the check and the interview, in the objection to the objection committee, and in approaching the courts when necessary. The office is in Tel Aviv, in Alon Tower 2, and meetings can also be arranged at unusual hours.

Security Clearance in the Navy: Preparing for the Check

Anyone who may face security clearance in the navy should read the questionnaire carefully, answer accurately and keep supporting documents at hand. Inconsistencies between the questionnaire and what is said later are a common source of difficulty, so it is worth reviewing the details in advance. If a problem arises, or if a decision has already been made, do not wait: the deadlines for an objection are short. A first conversation with a lawyer about security clearance in the navy can help clarify the options and the next steps in your case.

Frequently Asked Questions

Can I Object to a Decision to Disqualify a Clearance?

As a rule, yes. The objection is filed with the objection committee, and it is worth checking its deadlines immediately upon receiving the decision.

Is a Polygraph Mandatory?

Not in every role. It is usually accepted at the higher levels, according to the guidelines of the checking body. It is worth consulting before the test.

Does a Disqualification Mean the End of Service in the Navy?

Not necessarily. Sometimes it is possible to assign to a different role, and sometimes it is possible to object to the decision. The path depends on the circumstances.
