GIAC Security Essentials (GSEC)

Validates knowledge of access control, networking, cryptography, Linux and Windows security, cloud security and incident handling.

Summary

GSEC is GIAC's broad practitioner security certification. It tests networking, Linux, Windows, cryptography, cloud and incident handling in an open book exam that includes CyberLive tasks in live virtual machines.

Good fit if

  • You want a broad security credential with a hands-on, open-book exam
  • You have IT or sysadmin experience and want a security role
  • You want a respected credential without buying the SANS course

Look elsewhere if

What holders say

Worth more when an employer is paying, or when you already have the fundamentals

A self-identified SANS instructor told a candidate who barely passed to check for gaps in IT or CS fundamentals before buying more courses. Commenters say GIAC pays off mainly when employers pay.

FAQ

Is GSEC hard?

It is broad rather than deep. Most of the work is learning a wide range of topics, building a fast index and practising the CyberLive labs.

No. You can buy the $999 attempt on its own. SEC401 is the affiliated course and costs $8,780.

Is the GSEC exam open book?

Yes, for printed books and notes. Laptops, phones, electronic files and printed practice questions are not allowed.

What happens if I fail GSEC?

You can buy a retake for $899 within 30 days of your attempt deadline and must wait 30 days before testing again. After three failed attempts you wait a year.

How long is GSEC valid for?

4 years. Renew with 36 CPEs and a $499 fee, or by passing the exam again.
