• certifications (OSCP, CISSP, Security+, CEH) and frameworks (MITRE ATT&CK, NIST, ISO 27001) near the top
• incident scale and your role in it: alerts triaged, systems protected, findings reported
• tools named in the posting (SIEM, EDR, scanners) plus scripting ability

Before and after: how a Penetration Tester-style bullet improves

How to tailor your Penetration Tester resume in three steps

1. Mark the must-haves. Read the posting and highlight the tools, skills, and responsibilities it repeats or labels “required”.
2. Match them to your real experience. For each must-have, find the place in your history where you actually did it, and move that evidence to the top — using the posting’s wording where it is honest.
3. Cut what doesn’t help. Shorten or remove bullets that don’t support this particular job. Two strong, relevant lines beat six generic ones.

That’s exactly what renewed.cv automates: it extracts the requirements, rewrites your real experience around them, fact-checks the result against your original, and shows you a before/after match score.

Common Penetration Tester resume mistakes

• Burying certifications on page two
• Describing tools instead of outcomes such as incidents resolved or risk reduced
• Revealing confidential details instead of generalised, safe results

Recommended structure: Summary → Certifications → Skills and tools → Experience → Projects, CTFs and write-ups → Education.
