A SIM swapping attack moves a victim's phone number onto a subscriber identity module (SIM) card the attacker controls, through social engineering against a mobile carrier or a weak self-service recovery process, defeating any control that trusts a text message or phone call for verification. You will learn why this attack requires no action from the victim at all, why cryptocurrency holders and executives are consistently targeted, why the core vulnerability sits partly outside any individual's or organisation's direct control, and the personal and organisational defenses, warning signs, and incident response sequence that genuinely reduce risk despite that honest limitation. Every scenario in this course is explicitly hypothetical.
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.
