Quick answers about how Domain8 works, what's free, pricing, and the Pass Guarantee.
Yes. All of Domain 8 — Software Development Security — is 100% free: every lesson (watch and read), the adaptive practice quizzes, the flashcards, and a diagnostic that finds your weak spots. No credit card, and you don't even need an account to start.
Not to study Domain 8. You only need to create an account (email or Google sign-in) if you want to buy a pass for Domains 1–7, or to sync your progress across devices.
It's not a subscription — you pay once. Domain 8 is free; full access to all eight domains is a one-time access pass: 1 month for $99, the Exam Sprint (4 months) for $199, or Full Prep (8 months) for $299. Your access ends when the pass period is up; nothing auto-renews. If you buy another pass, the remaining time stacks.
If you complete the Domain8 program and don't pass the official CISSP exam, we extend your access free for one additional 60-day period so you can retake. It's a one-time, 60-day extension of access — not a cash refund. To qualify you need to have worked all eight domains in the app, completed at least two full-length mock exams, and submitted your official ISC2 result, in your own name, within 30 days of your exam.
No. Domain 8 is about reasoning over secure software development — the SDLC, common flaws, defenses, and testing — and applying managerial judgment. You won't write or debug production code.
Video and read-along lessons for every domain, adaptive best-answer practice questions, full CAT-style mock exams, spaced-repetition flashcards, a diagnostic that scores you by difficulty and question style, and a study plan that works backward from your exam date.
No. Each account is for a single named individual and can't be shared or resold. You can sign in on up to two devices (for example your laptop and phone), and your progress syncs between them.
Yes. Domain8 runs in any modern browser, and you can install it to your home screen like an app. On iPhone: Share → Add to Home Screen; on Android or desktop Chrome: the install icon. Signed-in progress follows you across devices.
No. Domain8 is an independent study aid and is not affiliated with, endorsed by, or sponsored by ISC2. “CISSP” is a registered trademark of ISC2. Our content is derived from publicly available sources for educational purposes.
If you request a refund within 7 days and haven't opened any Domain 1–7 lesson or started a mock exam, we'll refund you in full. Duplicate or accidental charges are always refunded. Beyond that, the Pass Guarantee covers you rather than a cash refund.
Securely by Stripe. We never see or store your card details. Payments are processed under our legal name, Clarent Advisory LLC.
Yes. Your progress is saved in your browser and, when you're signed in, synced to your account so you can pick up on another device. If you study signed out, progress is stored only on that device.
