Free official resources

What to know

• CISSP Certification Exam Outline: Official free CISSP exam outline with eight domains and weights; canonical ISC2 credential slug.
• Official CISSP Flash Cards: Official self-study hub listing free CISSP flash cards; study guide, practice tests, and training are paid.

The free path, in order

1. Start from the exam objectives / outline — it is the exact list of what the exam tests, and it is free. Study against it, not against a course's table of contents.

2. The vendor's structured training is paid, so the honest free route is: study the objectives, use free/low-cost reputable material, and budget only for the exam itself — see what it costs to earn and keep.

Free resources reduce what you spend to study; they do not reduce the exam fee and do not guarantee a pass. A course is not the certification.
