CCST Cybersecurity is the cheapest way into a recognised security certification from a major vendor, and almost nobody writes about it properly. Search for it and you get Cisco's own product pages, a Reddit thread asking whether it is worth it, and a wall of practice-test listings. Nothing that tells you what the exam actually contains or whether it beats spending three times the money on Security+.
This post answers both. The exam code is 100-160, it costs $125, and it runs for 50 minutes. Whether it is the right first certification depends almost entirely on one thing: whether the jobs you are applying for filter on Security+ by name.
What CCST Cybersecurity Actually Is
CCST stands for Cisco Certified Support Technician. It is Cisco's entry tier, sitting a level below CCNA, and it comes in several tracks. The security one is CCST Cybersecurity, exam 100-160.
The certification is aimed at people with no professional security experience: students, help-desk staff moving sideways, and career changers who need something on a CV that a recruiter recognises. There are no prerequisites. You do not need a CCNA, a degree, or documented work history to sit it.
Exams are booked through Certiport, Pearson VUE's certification arm, so the registration flow and the list of approved testing centres differ from the ones CCNA candidates use.
Exam Tip: CCST Cybersecurity is 40 to 50 questions in 50 minutes. That is roughly a minute per question with nothing spare. The exam rewards recognition rather than reasoning, so drilling questions until the answers are automatic beats deep study of any single topic.
The Five CCST Cybersecurity Exam Domains
Cisco publishes the 100-160 exam topics as five sections. Unlike CompTIA, which prints a percentage next to every domain, Cisco does not publish a public weighting for each CCST section, so treat all five as equally examinable.
| Domain | What it covers |
|---|---|
| Essential Security Principles | The CIA triad, vulnerabilities and threats, access management, basic encryption concepts |
| Basic Network Security Concepts | TCP/IP weaknesses, addressing, firewalls, VPNs, wireless security, secure access |
| Endpoint Security Concepts | Operating system hardening, antivirus and EDR, mobile device security, log interpretation, malware removal |
| Vulnerability Assessment and Risk Management | Vulnerability management process, threat intelligence sources, risk evaluation, disaster recovery |
| Incident Handling | Security monitoring, digital forensics basics, compliance frameworks, the incident response lifecycle |
Two things stand out if you have looked at Security+ before. First, the coverage map is almost identical, just shallower. Second, the networking content is heavier than you would expect from a security exam, which is unsurprising given Cisco wrote it. If you have never configured an interface or read a subnet mask, the Basic Network Security Concepts section is where you will lose marks.
Cisco does not publish the passing score for CCST exams, so ignore any site that quotes you a specific number. Score reports come back as pass or fail with section-level feedback.
CCST Cybersecurity vs Security+ vs ISC2 CC
These three are the realistic shortlist for a first security certification in 2026. The differences that matter are cost, recognition and what happens to the certification afterwards.
| CCST Cybersecurity | CompTIA Security+ (SY0-701) | ISC2 CC | |
|---|---|---|---|
| Exam price | $125 | $439 (as of 1 June 2026) | $199 |
| Questions | 40 to 50 | Up to 90 | 100 to 125, adaptive |
| Time | 50 minutes | 90 minutes | 2 hours |
| Performance-based tasks | No | Yes | No |
| Passing score | Not published | 750 of 900 | 700 of 1,000 |
| Annual fee | None | None | $50 maintenance fee |
| Validity | 5 years if earned on or after 15 July 2025 | 3 years | 3 years |
| DoD 8140 approved | No | Yes | No |
The price gap is the headline. CompTIA raised prices across its lineup in June 2026 and Security+ now sits at $439, which makes CCST Cybersecurity a little over a quarter of the cost. For someone paying out of their own pocket with no employer funding, that is the entire argument.
The recognition gap runs the other way, and it is just as decisive. Security+ is a DoD 8140 baseline certification, which means US federal and defence roles list it by name and will not accept a substitute. If that is the sector you are targeting, CCST Cybersecurity does not qualify you for anything, no matter how well you understand the material. Our DoD 8140 breakdown covers which certifications map to which work roles.
ISC2 CC sits between the two on price and has no performance-based questions, but the free enrolment route closed on 20 May 2026. If you were holding out for a free voucher, that window has shut, and existing vouchers only run to 31 December 2026. Our ISC2 CC vs Security+ comparison goes deeper on that pair.
The Renewal Rule That Changed in July 2025
CCST used to be a lifetime certification. That changed.
Certifications earned before 15 July 2025 do not expire. Certifications earned on or after 15 July 2025 are valid for five years, renewed by passing any CCST exam or any higher-level Cisco exam.
In practice that renewal path is generous. Passing CCNA within five years renews your CCST automatically, and CCNA is where most CCST holders are heading anyway. Compare that with Security+, which needs 50 continuing education units every three years or a retake, and CCST comes out ahead on long-term admin.
Is CCST Cybersecurity Higher Than CCNA?
No, and this is the most common misconception about the credential. CCST is Cisco's entry tier and CCNA is the associate tier above it. CCST Cybersecurity is not a security version of CCNA.
The exam that plays that role is CCNA Cybersecurity, exam 200-201, which replaced CyberOps Associate. That is a considerably harder exam pitched at working SOC analysts. We covered what changed when CyberOps became CCNA Cybersecurity if you are weighing that step.
A sensible Cisco progression looks like this:
- CCST Cybersecurity for the fundamentals and something on the CV within a month
- CCNA (200-301) for the networking depth that every security role assumes you have
- CCNA Cybersecurity (200-201) for SOC and blue team work
Skipping straight to CCNA is entirely reasonable if you already work in IT. CCST exists for people who need a win before they have the confidence or the background for a 120-minute associate exam.
How Long CCST Cybersecurity Takes to Prepare
Most candidates with some IT exposure need three to four weeks of evening study. Complete beginners should plan for six.
The exam is broad and shallow, which changes how you should revise. Reading a 600-page cert guide cover to cover is the wrong strategy for a 50-minute recognition test. A better approach:
- Week 1: Essential Security Principles and Basic Network Security Concepts, the two sections with the most unfamiliar vocabulary
- Week 2: Endpoint Security Concepts and Vulnerability Assessment, both of which reward memorising tool categories rather than tool specifics
- Week 3: Incident Handling, then timed practice questions across all five sections
- Week 4: Practice questions only, until you are answering in under 45 seconds each
The timing discipline matters more here than on any other entry-level security exam. Candidates who fail CCST Cybersecurity usually knew the material and ran out of clock.
Who Should Sit It, and Who Should Not
Sit CCST Cybersecurity if you are self-funding, have no security certification at all, want something recognisable within a month, or are already on a Cisco path towards CCNA. The five-year validity and the renew-by-CCNA rule make it low maintenance.
Skip it if you are targeting US federal or defence work, already hold Network+ or A+ and have real IT experience, or have employer funding that would cover Security+. In those cases CCST becomes a $125 detour on the way to the certification the job advert actually names. Our cybersecurity certification roadmap lays out the full sequence from entry level upwards.
Frequently Asked Questions
Is CCST certification worth it?
For self-funded beginners with no other security certification, yes. At $125 it is the cheapest recognised entry point from a major vendor, and it renews for free when you later pass CCNA. It is not worth it if you already hold Network+ or if you need a DoD 8140 baseline certification, because CCST is not on that list.
Is CCST higher than CCNA?
No. CCST is Cisco's entry-level tier and CCNA is the associate tier above it. Passing any CCNA exam renews a CCST, which tells you which way the hierarchy runs.
Is CCST better than CompTIA?
It is cheaper and faster, not better. Security+ carries far more recruiter recognition in the United States, includes performance-based questions, and qualifies for DoD 8140 roles. CCST Cybersecurity wins on price and on the five-year renewal cycle, so it suits candidates paying for themselves rather than candidates chasing a specific job listing.
How much does a CCST certification cost?
The CCST Cybersecurity exam (100-160) costs $125 USD. There is no annual maintenance fee, and certifications earned on or after 15 July 2025 stay valid for five years.
Can I take CCST Cybersecurity online?
Yes. CCST exams are delivered through Certiport, which offers both testing centre and online proctored options. An authorised proctor supervises the session in real time after an online identity check, so the requirements match any other remote exam: a quiet room, a clear desk and a working webcam.
