How to address hiring managers in your penetration tester cover letter greeting

Goodbye, "Dear Sir/Madam" or "To whom it may concern!"

The salutation of your penetration tester cover letter is how you kick off your professional communication with the hiring managers.

And you want it to start off a bit more personalized and tailored, to catch the recruiters' attention.

Take the time to find out who's recruiting for the role (via LinkedIn or the company page).

If you have previously chatted or emailed the hiring managers, address them on a first or last name basis.

The alternative is a "Dear HR team" or "Dear Hiring Manger", but remember that a "Dear Ms. Simmons" or "Dear Simon," could get you farther ahead than an impersonal greeting.

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Recruiting Team,
  • Dear [Department Name] Director,
  • Dear Mr./Ms. [Last Name],
  • Dear [First Name] [Last Name],
  • Dear Dr. [Last Name],

First introductions in your penetration tester cover letter
