Common Cybersecurity Mistakes New Defense Contractors Make

Begin with obligations and data

Cybersecurity readiness should be based on the contract, information handled, and systems involved. A new contractor can waste money or create risk by implementing a generic solution without defining these first.

Common mistakes

• Assuming all business information is CUI, or ignoring CUI because it is unclassified
• Applying an old revision or checklist without checking the governing requirement
• Treating a cloud product purchase as complete compliance
• Claiming certification based only on a self-assessment or submitted score
• Excluding relevant people, services, or data flows from scope
• Ignoring subcontractor obligations and evidence

Use a better sequence

1. 01Read applicable clauses and official program guidance.
2. 02Identify information and map where it flows.
3. 03Define the relevant environment and accountable owners.
4. 04Implement, document, and verify required controls.
5. 05Determine the correct assessment, reporting, and maintenance actions.

Keep claims supported

Avoid claiming compliance, a passing score, or required certification without evidence. Specific obligations and assessment routes can change, so verify current requirements before bidding and after modifications. Readiness is an operating discipline, not a badge purchased once.
