Common Cybersecurity Resume Mistakes

Not listing certifications prominently — These are often required for the role

Being too vague — "Responsible for security" tells nothing; specifics matter

Missing compliance frameworks — List every framework you have worked with

Ignoring business impact — Connect security work to business outcomes (cost savings, risk reduction)

Outdated tools — Keep your tools list current

Security Clearances

If you hold a security clearance, list the level (Secret, Top Secret, TS/SCI) and status (active, inactive) near the top of your resume. Do not include specific details about classified work.
