The CompTIA Security+ is one of the most sought-after cybersecurity certifications in the world. One of its biggest advantages is that it has no mandatory prerequisites — anyone can register and take the exam regardless of education or experience level. However, CompTIA provides recommended experience guidelines, and understanding these recommendations helps you gauge your readiness and plan your preparation effectively.
This comprehensive guide covers every requirement you need to know: recommended experience, exam registration logistics, identification requirements, testing options, renewal obligations, and how to prepare if you are starting from scratch.
While CompTIA does not enforce prerequisites, they publish clear recommendations for candidates considering the Security+ exam:
These recommendations exist because Security+ assumes foundational networking knowledge. If you cannot explain how TCP/IP works, what a subnet mask does, or the difference between UDP and TCP, you should study networking fundamentals before diving into security-specific content.
This is the most common question prospective candidates ask. The honest answer depends on your existing knowledge:
Many successful candidates skip Network+ entirely, especially those with practical IT experience. However, if networking concepts feel foreign, investing 4-6 weeks in Network+ study material (even without taking the exam) will make Security+ significantly easier to learn.
To register for and take the CompTIA Security+ exam, you must meet these logistical requirements:
Candidates must be at least 13 years old. Those under 18 years of age must have verifiable parental or guardian consent before testing. CompTIA provides consent forms through their website.
You must present two forms of identification at the testing center or during online proctoring:
| Primary ID (Required) | Secondary ID (Required) |
|---|---|
| Government-issued photo ID (driver's license, passport, military ID, state ID card) | Credit/debit card with signature, school ID, second government ID, social security card |
Critical: The name on both IDs must match your exam registration name exactly. Even minor discrepancies (middle name present on one but not the other) can result in being turned away at the testing center.
The CompTIA Security+ exam voucher costs $404 USD at list price. Options for reducing cost include:
CompTIA offers two testing modalities through Pearson VUE:
Pearson VUE operates thousands of testing centers worldwide. In-person testing provides a controlled, distraction-free environment with standardized equipment. You must arrive 15 minutes early, store personal belongings in a locker, and follow all testing center rules.
Online proctored testing (OnVUE) allows you to take the exam from your home or office. Requirements include:
Online proctoring is convenient but comes with risks: technical issues (internet drops, software crashes) can disrupt your exam, and the process of room scanning and ID verification can add 15-20 minutes before the exam starts.
| Parameter | Detail |
|---|---|
| Number of Questions | Up to 90 (mix of multiple-choice and PBQs) |
| Time Limit | 90 minutes |
| Passing Score | 750 out of 900 |
| Question Types | Multiple-choice, multiple-select, performance-based (PBQs) |
| Validity Period | 3 years from passing date |
| Renewal Options | 50 CEUs in 3 years, or pass a higher-level CompTIA exam |
After passing Security+, your certification is valid for 3 years. To maintain it, you must earn 50 Continuing Education Units (CEUs) within the 3-year cycle and pay a $75 annual renewal fee ($225 total over 3 years). CEUs can be earned through:
CompTIA Security+ is one of the most important certifications for U.S. government and defense contractor positions. It satisfies DoD Directive 8570 (and the newer 8140 framework) requirements for:
This DoD approval makes Security+ effectively mandatory for many government cybersecurity positions and a requirement on thousands of defense contractor job postings.
If you are a complete beginner with no IT background, here is a realistic preparation roadmap:
Total investment for a beginner: approximately 4-6 months of consistent study (1-2 hours daily).
There are no mandatory prerequisites. CompTIA recommends holding the Network+ certification and having at least 2 years of IT administration experience with a security focus, but anyone can register and sit the exam.
No, Network+ is recommended but not required. However, strong networking fundamentals (TCP/IP, DNS, DHCP, ports, protocols) are essential for understanding Security+ content, so candidates without networking knowledge should study those topics first.
CompTIA requires candidates to be at least 13 years old. Candidates under 18 must have parental consent to take the exam.
No degree is required. CompTIA Security+ is an industry certification open to anyone willing to pay the exam fee and demonstrate the required knowledge by passing the test.
The exam voucher costs $404 USD at list price. Discounts are available through CompTIA bundles, academic pricing, and employer sponsorship programs.
Yes. CompTIA Security+ meets DoD 8570/8140 requirements for IAT Level II, IAM Level I, and IASAE Level I positions. It is one of the most commonly required certifications for government and defense contractor roles.
You need two forms of identification: one primary (government-issued photo ID such as a driver's license or passport) and one secondary (credit card, school ID, or second government ID). Both must display your name exactly as registered.
Yes. CompTIA offers online proctored testing through Pearson VUE in addition to in-person testing at Pearson VUE test centers worldwide.
