A practical course for the volunteer maintainer of a public open source project: keeping your own dependencies and release pipeline clean, publishing a Software Bill of Materials (SBOM) and provenance for every release, showing your posture with badges and scorecards, running a real vulnerability disclosure process, and exactly what Safeguard's free tier for maintainers covers, read precisely rather than assumed.
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.
