The GCIA exam is the official GIAC exam behind the GIAC Certified Intrusion Analyst (GCIA) certification, validating the skills measured by the GIAC Certified Intrusion Analyst credential. It sits at the Practitioner level of the GIAC certification program. It also connects to SANS SEC503: Intrusion Detection In-Depth, GIAC Experienced Intrusion Analyst (GX-IA), so the knowledge you build here carries over to those tracks as well.

The GCIA exam contains 106 questions to be completed within 240 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the ValidVCE test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

The passing score for the GCIA exam is 67%, and the official registration fee is USD 999. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 508 practice questions on ValidVCE, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

No mandatory prerequisites. Experience with networking, security concepts, and intrusion detection is recommended. Requirements can change when GIAC revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
