How to structure it

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 Chief Information Security Officer
I am writing to apply for the Chief Information Security Officer role at [Company Name]. With a career spanning security operations, governance and executive leadership, I bring the strategic oversight and technical credibility needed to protect complex, regulated environments.
In my most recent position, I led the organisation through a comprehensive review of its incident response capability. By restructuring the response plan, running live simulations with executive participation and embedding lessons learned into policy, we reduced the time from detection to containment and improved board confidence in our cyber resilience. I also directed an ISO 27001 certification program that unified risk treatment across previously siloed business units.
I am particularly drawn to [Company Name] because [add one genuine, specific reason: a project, value, or market position you can point to]. I want to contribute my experience in aligning security strategy with business goals to an organisation that takes its obligations to customers and regulators seriously.
Thank you for considering my application. My resume is attached, and I would welcome the opportunity to discuss how I can help [Company Name] manage cyber risk and strengthen its security posture.
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.
