CompTIA Security+ Guide: Is It Worth It for a Career Change Into IT?
What the exam actually tests, what it costs to sit and to renew, and how it sits alongside the hands-on IT experience most security employers still want.

CompTIA Security+ is the certification most often suggested to people moving into IT from another field. It is a single 90-minute, 90-question exam scored from 100 to 900 with a pass mark of 750 (cybersecurityguide.org, undated), and it costs $425 when bought directly from CompTIA's store as of July 2025 (Destination Certification, July 2025), with a standard retail price listed at $439 for 2026 (Training Camp, 2026). It is a reasonable first credential — but it is a knowledge test, not a job offer, and the roles it points at usually also expect IT experience.
This guide covers what the exam measures, the skills worth building around it, a sequencing plan with checkpoints, and how self-study, bootcamps and degree routes compare on cost and time.
The Skills Landscape
Security work is a small occupation that is growing quickly. The U.S. Bureau of Labor Statistics counted 192,900 information security analyst jobs in 2025 and projects 21% growth from 2025 to 2035 — described as much faster than average — equal to about 40,600 additional jobs over the decade (BLS, 2025).
That matters for a career changer in two ways. First, 40,600 openings spread over ten years is real demand but not a flood; you are competing with people already inside IT. BLS notes that many information security analysts have prior experience in an IT department, often as a network and computer systems administrator (BLS, 2025). Second, the entry door is narrow at the top: BLS lists a bachelor's degree as the typical entry-level education, while also stating that some workers enter with a high school diploma plus relevant industry training and certifications, and that many employers prefer to hire candidates who hold an information security certification (BLS, 2025).
The wider tech market gives some sense of volume. CompTIA's analysis of BLS data recorded 271,483 new tech job postings in April, more than 575,000 active tech postings that month, and a tech occupation unemployment rate of 3.5% (CompTIA, undated). In the same analysis, active postings for cybersecurity engineers and analysts rose 23.2% since January, alongside systems engineers and architects (42.7%), software developers and engineers (32.3%) and tech support specialists (16.1%) (CompTIA, undated).
The experience filter is the part worth reading twice: 20% of those April postings sought workers with zero to three years of experience, 28% specified four to seven years, and 17% specified eight or more (CompTIA, undated). Roughly one posting in five is aimed at the group a career changer belongs to. Security+ is best treated as a way to qualify for that fifth, usually via a support, systems or network role first, rather than as a direct route into an analyst title.
Core Skills to Learn
The exam itself tells you what to study. Security+ covers five weighted domains: Attacks, Threats and Vulnerabilities (24%), Architecture and Design (21%), Implementation (25%), Operations and Incident Response (16%), and Governance, Risk and Compliance (14%) (cybersecurityguide.org, undated). Weight your study time to match.
- Networking fundamentals. Nearly every security concept assumes you understand addressing, routing, ports and traffic flow. CompTIA recommends a Network+ certification before Security+, though there are no formal prerequisites (cybersecurityguide.org, undated). Estimated time: 6-10 weeks part-time, whether or not you sit the Network+ exam.
- Operating system administration. BLS notes many analysts arrive from network and computer systems administrator roles (BLS, 2025) — employers hire people who can actually configure a machine. Learn it by building a home lab with free virtualisation software and running one Linux and one Windows server you maintain yourself. Estimated time: 8-12 weeks alongside other study.
- Threats, attacks and vulnerabilities. The single largest standalone exam domain at 24% (cybersecurityguide.org, undated). Learn it by mapping each attack type in the exam objectives to a demonstration you can run or watch in your own lab. Estimated time: 3-5 weeks.
- Secure implementation. At 25% the heaviest domain (cybersecurityguide.org, undated): identity and access management, cryptography in practice, secure protocols and endpoint hardening. Learn it by enforcing multi-factor authentication, certificates and least-privilege accounts in your lab rather than reading about them. Estimated time: 4-6 weeks.
- Architecture and design. 21% of the exam (cybersecurityguide.org, undated), and the part interviewers probe when they ask why a control exists. Practise by drawing the network diagram of your own lab and marking where each control sits. Estimated time: 3-4 weeks.
- Operations and incident response. 16% of the exam (cybersecurityguide.org, undated). Learn it by writing a short incident report for a simulated event in your lab — what happened, what you checked, what you'd change. Estimated time: 2-4 weeks.
- Governance, risk and compliance. 14% of the exam (cybersecurityguide.org, undated) and the vocabulary that lets you talk to non-technical managers. Estimated time: 2-3 weeks.
- Exam technique. You get a maximum of 90 questions in 90 minutes and need 750 out of a 100-900 scale to pass (cybersecurityguide.org, undated), which is one minute per question including performance-based items. Estimated time: 2-3 weeks of timed practice at the end.

Building a Learning Plan
This sequence assumes 6-10 hours a week. Compress it if you already work in IT; stretch it if you are studying around a full-time job in another field.
- Baseline and lab build — 2-3 weeks, 5-8 hours per week. Install virtualisation software, stand up one Windows and one Linux virtual machine, and connect them on a private network. Milestone: you can rebuild both machines from scratch in under an hour without instructions.
- Networking to Network+ level — 6-10 weeks, 6-8 hours per week. Work through the Network+ objectives even if you do not sit that exam; CompTIA recommends it as background for Security+ (cybersecurityguide.org, undated). Milestone: you can capture traffic between your two lab machines and explain what each packet exchange is doing.
- Security+ domains in weight order — 10-14 weeks, 6-10 hours per week. Start with Implementation (25%) and Attacks, Threats and Vulnerabilities (24%), then Architecture and Design (21%), Operations and Incident Response (16%) and Governance, Risk and Compliance (14%) (cybersecurityguide.org, undated). Milestone: one lab artefact per domain — a hardened server, an attack demo, a network diagram, an incident write-up, a risk register.
- Timed practice — 3-4 weeks, 6-8 hours per week. Milestone: two consecutive full-length practice attempts at or above the 750 pass mark on the 100-900 scale (cybersecurityguide.org, undated), both finished inside 90 minutes.
- Book the exam and apply in parallel — 4-8 weeks. Buy the voucher ($425 from CompTIA's store as of July 2025, per Destination Certification; $439 standard retail listed for 2026, per Training Camp) and start applying to support, helpdesk and junior systems roles while you wait. Only about 20% of April tech postings targeted zero to three years of experience (CompTIA, undated), so widen the search beyond security titles. Milestone: ten applications sent before exam day.
- Plan the renewal before you need it — ongoing, 2-4 hours per month. Security+ 'ce' expires three years from the certification date and must be retaken if it lapses (DoD COOL, citing CompTIA policy, undated). Milestone: a written three-year plan covering 50 CEUs and the $50 annual maintenance fee (Infosec Institute, undated).
Realistic end-to-end range: 3-6 months to pass if you already work in IT, 6-18 months from a standing start to a first paid technical role.
Comparing Learning Paths
| Path | Approximate cost | Typical duration | What the sources document |
|---|---|---|---|
| Self-study plus exam voucher | $425 for the SY0-701 exam from CompTIA's store as of July 2025 (Destination Certification, 2025); $439 standard retail for 2026 (Training Camp, 2026), plus books or video courses you choose | 3-6 months part-time at 6-10 hours per week | No published pass or hiring rate in these sources. BLS (2025) states many employers prefer candidates with an information security certification |
| Exam-prep bootcamp | $1,895 to $2,799 depending on provider (cybersecurityguide.org, undated), plus the exam fee unless bundled | Commonly a one- to two-week intensive, after self-paced prework | No completion or placement figures published in these sources — ask any provider for its own pass rate and how it is measured before paying |
| Degree route | Not stated in these sources; varies widely by state, institution and residency status — check published tuition directly | Typically four years full-time for a bachelor's | BLS (2025) lists a bachelor's degree as the typical entry-level education for information security analysts, while noting some workers enter with a high school diploma plus industry training and certifications |
| Stacking a higher CompTIA certification | Exam fees for CySA+, PenTest+ or SecurityX, which CompTIA prices separately | After Security+, usually a further 3-9 months of study each | Earning CySA+, PenTest+ or SecurityX automatically renews Security+ (Infosec Institute, undated), replacing the CEU route |
| Maintaining what you hold | $50 annual maintenance fee, $150 over three years, plus 50 CEUs (Infosec Institute, undated) | Spread across the three-year certification period | Certifications earned on or before 31 December 2010 are 'certified for life' and need no renewal (DoD COOL, citing CompTIA policy, undated) |
The honest comparison: the cheapest route to the same credential is self-study plus the voucher. A bootcamp at $1,895 to $2,799 (cybersecurityguide.org, undated) buys structure and pace, not a different certificate. A degree answers a different question — BLS (2025) names it as the typical entry-level education — but costs years rather than months.
Frequently asked questions
What does Security+ cost from start to finish?
The exam itself is $425 from CompTIA's official store as of July 2025 (Destination Certification, July 2025), with a standard retail price of $439 listed for 2026 (Training Camp, 2026). Self-study materials are extra and vary. An exam-prep bootcamp ranges from $1,895 to $2,799 depending on the provider (cybersecurityguide.org, undated). Then add renewal: 50 CEUs plus a $50 annual maintenance fee, $150 across the three-year cycle (Infosec Institute, undated). Prices change, so check CompTIA's store before budgeting.
How long does it take to pass with no IT background?
Expect 6-12 months part-time if you are starting from zero, and 3-6 months if you already work in IT. CompTIA recommends two years of IT security experience and a Network+ certification beforehand, though neither is a formal prerequisite (cybersecurityguide.org, undated). The exam is a maximum of 90 questions in 90 minutes, scored 100-900, with 750 to pass (cybersecurityguide.org, undated).
Does Security+ actually improve hiring odds?
No source here publishes a hiring rate for certificate holders, and no certification guarantees an interview. What is documented: BLS (2025) states many employers prefer to hire candidates who have information security certification, and that some workers enter the occupation with a high school diploma plus relevant industry training and certifications rather than a degree. CompTIA's analysis found 20% of April tech job postings sought zero to three years of experience (CompTIA, undated) — so the certificate competes for roughly one posting in five, and usually alongside demonstrable hands-on work.
Should I do Network+ first?
There are no formal prerequisites for Security+, but CompTIA recommends Network+ and two years of IT security experience (cybersecurityguide.org, undated). If you have never configured a network, study the Network+ material for 6-10 weeks first even if you skip that exam — several Security+ domains, including Architecture and Design at 21% and Implementation at 25% (cybersecurityguide.org, undated), assume you already understand it.
What happens after three years?
A CompTIA CE certification such as Security+ 'ce' expires three years from the date you certify; if you do not renew within that window you are no longer certified and must retake the exam (DoD COOL, citing CompTIA policy, undated). Renewal means 50 CEUs plus $50 per year, $150 total (Infosec Institute, undated). CEU activities include up to 50 CEUs for a qualifying course, 10 for a conference and 10 for a live webinar, with at least 50% of content tied to exam objectives (Master of Project Academy, 2026). Passing CySA+, PenTest+ or SecurityX renews it automatically (Infosec Institute, undated). Certifications earned on or before 31 December 2010 never expire (DoD COOL, undated).
Where can I check which certifications employers near me ask for?
BLS directs readers to CareerOneStop for certification information (BLS, 2025). Requirements vary by employer and by state — federal and defense-linked roles in particular tend to specify credentials explicitly — so read a sample of live postings in your own area before committing to an exam fee.
