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 Cyber Security Engineer
I am applying for the Cyber Security Engineer role at [Company Name]. My background sits across security operations and cloud security engineering, and the blend of monitoring, incident response and control design in this position matches the work I do day to day.
In my current role I rebuilt our alert triage process after a run of low-severity indicators slipped past review. I mapped our detection rules against MITRE ATT&CK, retired the ones that fired constantly without adding value, and wrote new Splunk searches for the blind spots. Average triage time per alert came down from roughly 20 minutes to under 5, and the team caught two genuine intrusions in the following quarter that the old rules would have missed. I also led containment for a credential-stuffing attempt against our customer portal, locking the affected accounts and adding conditional access rules overnight, then wrote the post-incident review that led to a permanent change in how authentication is handled.
[add one genuine, specific reason: a project, value, or market position you can point to]
Thank you for considering my application. My resume is attached and covers my technical background and certifications in more detail, and I would welcome the chance to talk through how I would approach the security challenges your team is facing.
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.
