Penetration Tester cover letter template
A structured letter with example content specific to this role. Replace the bracketed placeholders and adjust the details to the job you're actually applying for.
How to structure it
Opening
Name the role and, in one line, the strongest reason you're a fit. Skip the throat-clearing.
Middle
One or two paragraphs of real, specific evidence: what you did, and the result. This is where most letters go generic. Yours shouldn't.
Why this employer
One genuine, specific reason you want this job at this company, not any company. Vague enthusiasm reads as a template that wasn't customised.
Close
Thank them, note your resume is attached, and make it easy to reach you.
Re: Application for Penetration Tester
I'm writing to apply for the Penetration Tester role. I've spent my career finding the weaknesses attackers would use before they get the chance, and I'd bring that same discipline to your security testing program.
In a recent engagement I was tasked with assessing an externally facing web application. Using Burp Suite and manual testing I identified a broken access control flaw that allowed a standard user to view other customers' account data by manipulating a session parameter. I rated the finding, wrote up a clear reproduction path and remediation steps, and worked with the development team through two rounds of retesting until the fix was confirmed closed.
[add one genuine, specific reason: a project, value, or market position you can point to] is what draws me to [Company Name] specifically. I want to apply my testing skills somewhere the findings change how systems get built and defended.
Thank you for considering my application. I've attached my resume and would welcome the chance to discuss how my testing experience and reporting approach could support your security team.
Getting it right
- Keep it to one page. A hiring manager spends seconds on this before deciding whether to read your resume.
- Address a named person where you can find one, rather than "To Whom It May Concern".
- Don't repeat your resume line for line. Use the letter to add context a bullet point can't: why this role, why now, why here.
- Match the tone of the job ad. A formal listing calls for a formal letter; a casual one gives you room to write more like yourself.
This is a starting point, not a guarantee of interviews. Make it specific to the actual employer before you send it.
