What to know
- CISSP Certification Exam Outline.: RoleMath records this against exam CISSP and has not verified whether that is still the current exam — check the vendor's page before relying on it. Official free CISSP exam outline with eight domains and weights. (noted when we read this source, 2026-06-30)
- CISSP Exam Cram - all 8 domains: RoleMath records this against exam CISSP (2024 outline) and has not verified whether that is still the current exam — check the vendor's page before relying on it. 7h56m across all eight domains - the most complete free CISSP course found. Uploaded 2022-03-18, which pre-dates the April 2024 outline refresh, so it has to be paired with the same author's 2024 addendum. (noted when we read this source, 2026-08-05)
- Official CISSP Flash Cards: RoleMath records this against exam CISSP and has not verified whether that is still the current exam — check the vendor's page before relying on it. Official self-study hub listing free CISSP flash cards; study guide, practice tests, and training are paid. (noted when we read this source, 2026-06-30)
- CISSP 2024 refresh addendum: RoleMath records this against exam CISSP (2024 outline) and has not verified whether that is still the current exam — check the vendor's page before relying on it. 2h38m uploaded 2024-03-20 covering what the April 2024 outline refresh changed. Required alongside the 2022 cram, which pre-dates it. (noted when we read this source, 2026-08-05)
- Destination Certification CISSP MindMaps (free video series): The page states no exam outline version or publication date for the material — check it against the official outline before relying on coverage. Downloads require an email address. Made by a provider that also sells a paid CISSP course. (noted when we read this source, 2026-07-30)
- CISSP MindMap series: RoleMath records this against exam CISSP (2024 outline) and has not verified whether that is still the current exam — check the vendor's page before relying on it. Mind-map walkthroughs by domain, strongest on Domain 3. A revision aid rather than first-pass instruction. The playlist holds 23 videos against a vendor index claiming 30, and the printable PDF and audio versions require submitting your details - the videos do not. (noted when we read this source, 2026-08-05)
- CISSP-Study-Resources (open-source study guides by domain): Maintained by one person who passed the exam in April 2025; it is not reviewed by ISC2 and its currency depends on that maintainer. Treat the official exam outline as authoritative on scope. (noted when we read this source, 2026-07-30)
- ISC2 CISSP Knowledge Check Quiz (official): Short — it samples the style of questioning rather than measuring readiness, and a good score is not evidence you are ready to sit. (noted when we read this source, 2026-07-30)
- Official CISSP flash cards: RoleMath records this against exam CISSP (2024 outline) and has not verified whether that is still the current exam — check the vendor's page before relying on it. Terminology drills across all eight domains. Access is a lead-generation form asking for name, email, phone, company and country - not a light signup. Recall only; it will not prepare anyone for CISSP's judgement-based scenario items. (noted when we read this source, 2026-08-05)
The free path, in order
1. Start from the exam objectives / outline — it is the scope the certifying body itself publishes, and where a vendor also publishes domain weightings they are in it. It may not be a comprehensive list of every exam topic. Study against it, not against a course's table of contents. Where the entry below records an exam version RoleMath has not verified as current, confirm on the vendor's page that you are reading the outline for your exam before you study against it.
2. Work the free structured course(s) above to build the skills — first check each one against What to know above, and where a course was written for a different exam version than the one you will sit, treat it as background rather than as your main preparation. Treat official material as scope authority and community material as instruction; use official sample questions where they exist.
3. Free study lowers what you spend preparing, not what the exam itself costs — see what it costs to earn and keep.
Free resources reduce what you spend to study. No resource guarantees a pass, and a course is not the certification.
