What happens if I fail the exam?

You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.

How long is a certificate valid?

The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.

About this course

A defensive course in the classic intruder and malware taxonomy and the firewall architectures built to answer them: threat actor categories, intrusion detection and prevention, honeypots, viruses through botnets, layered malware detection, and firewall generations from packet filters to zero trust segmentation. It closes with an honest map of where a software supply chain platform overlaps with this ground and where dedicated network security tooling remains necessary.

Common questions

How much does Safeguard Academy cost?

Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.

What are the prerequisites?

None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
