A practitioner's course on protecting availability against distributed denial of service attacks. You will learn the conceptual attack categories, capacity planning and graceful degradation as design philosophies, rate limiting and traffic control mechanics and their limits, incident response and communication specific to an availability event, and the testing practice that validates defenses before an attacker does it involuntarily.
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.
