A deep, practitioner-level course on what a digital signature actually proves, how certificate chains and certificate authorities establish trust, and how revocation, transparency and key custody hold that trust together over time. You will finish able to evaluate a signing system end to end, from key generation through code signing, timestamping and software supply chain attestation, and to spot the custody and validation mistakes that undermine an otherwise correct cryptographic design.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
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.
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.
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.
