Key Differences Between CS0-002 and CS0-003 – What’s New in the CySA+ Exam

In the fast-paced world of cybersecurity, it’s essential for both professionals and certifications to evolve. The CompTIA Cybersecurity Analyst (CySA+) certification has long served as a foundational credential for those working in threat detection, response, and vulnerability management. With the recent release of the CS0-003 version of the exam, it’s crucial for learners and professionals to understand what’s new and how it compares with the now-retired CS0-002 version.

If you’re pursuing or renewing a CySA+ certification, you’ve likely come across both versions. The CS0-002 exam officially retired on December 5, 2023, and its successor, CS0-003, launched earlier that year on June 6. Whether you’ve already been studying for CS0-002 or are just beginning your CySA+ journey, understanding the differences between these two versions can help you create an efficient and up-to-date study plan.

This article will walk through what has changed from CS0-002 to CS0-003, explain why those changes matter, and help you align your preparation to succeed on the newest exam version.

A Quick Refresher on the CySA+ Exam

The CySA+ certification sits in the middle of CompTIA’s security pathway. It bridges the gap between foundational certifications like Security+ and more advanced credentials like CASP+ or PenTest+. It validates a candidate’s ability to use behavioral analytics to identify and combat cybersecurity threats through continuous security monitoring.

The certification is ideal for professionals working in security operations centers (SOCs), conducting threat hunting, and managing incident response procedures. It’s also suitable for aspiring security engineers and analysts looking to move into more advanced roles.

Why CompTIA Released the CS0-003 Version

Cybersecurity evolves constantly, with new attack vectors, toolsets, and defense mechanisms appearing at an unprecedented pace. To remain relevant, certification vendors like CompTIA update their exams every three years. These updates ensure that certification holders are tested on current tools, methods, and best practices aligned with today’s threat landscape.

The CS0-003 exam reflects this evolution. It builds upon the foundation laid by CS0-002 but updates the scope to include new automation tools, cloud and mobile security best practices, and more advanced concepts in threat intelligence and response.

Exam Format: What Hasn’t Changed

Although CompTIA has significantly updated the domain structure and content in the transition from CS0-002 to CS0-003, the exam format itself has remained largely consistent. This is good news for candidates who have taken other CompTIA exams or who have studied CS0-002 content before switching to the new version. The CySA+ exam retains its familiar format, allowing test takers to focus their efforts on updated concepts and tools rather than worrying about changes in the test structure.

Below are the details that have not changed in the CS0-003 exam format.

1. Maximum Number of Questions: 85

The CySA+ CS0-003 exam includes a maximum of 85 questions, just like its predecessor. While the number may vary slightly, the upper limit remains consistent. Candidates can expect a mix of multiple-choice questions and performance-based tasks.

The exact number of questions you encounter may depend on the adaptive nature of the exam system. However, 85 is the cap, and most candidates will face somewhere between 75 and 85 questions.

This total includes:

Single- and multiple-answer multiple-choice questions
Scenario-based questions
Performance-based questions (PBQs) that simulate real-life cybersecurity tasks

2. Exam Duration: 165 Minutes

Test takers have 165 minutes (2 hours and 45 minutes) to complete the exam. This time allotment is the same as with CS0-002 and is generally sufficient for candidates who are familiar with the material and prepared to handle performance-based challenges.

Time management is crucial. You should aim to complete:

1 question every 2 minutes or less to stay on pace
Allocate more time for PBQs, which typically take longer than multiple-choice questions

Plan to flag and return to tougher questions or PBQs later if they slow you down. There’s no penalty for skipping and returning, so pacing yourself is a smart strategy.

3. Question Types: Multiple-Choice and Performance-Based

CySA+ is not just a knowledge exam. It evaluates your ability to analyze real-world scenarios, make decisions based on security data, and perform security operations tasks using simulated environments.

There are two primary types of questions:

a. Multiple-Choice Questions

These questions test your knowledge and decision-making skills. They include:

Single-response questions: Choose one correct answer
Multiple-response questions: Choose two or more correct answers

You might be presented with a situation that requires you to select the best security control, identify a vulnerability, or recommend a response strategy based on logs or tool output.

b. Performance-Based Questions (PBQs)

PBQs simulate practical tasks that analysts face in the workplace. These are not hypothetical—they often involve:

Reviewing SIEM dashboards and identifying malicious activity
Interpreting packet captures from Wireshark
Analyzing vulnerability scan output from Nessus or OpenVAS
Selecting appropriate incident response steps
Prioritizing remediation actions based on real-time data

PBQs test critical thinking and applied knowledge. You won’t be asked to type long commands but will be expected to understand output and select the correct response based on realistic scenarios.

Tips for PBQs:

Don’t get stuck – flag them and come back if they take too long
Practice interpreting security tool output before exam day
Exam-Labs simulations can help you build confidence for PBQs

4. Passing Score: 750 (On a Scale of 100–900)

To pass the CS0-003 exam, you must score 750 or higher on a 100–900 scale. This standardized scoring system helps normalize exam difficulty across different versions and candidate groups.

What does a score of 750 mean in terms of actual questions? CompTIA doesn’t reveal exact scoring methods, but it’s estimated that scoring 750 typically requires correctly answering around 80–85% of the questions. However, performance-based questions may carry more weight than traditional multiple-choice ones.

Important notes:

There is no partial credit for multiple-response questions. If the question asks for 3 answers and you get 2 correct, you get no credit.
PBQs are scored with greater nuance, but details are not publicly disclosed.

5. Delivery Options: In-Person and Online Proctored

The CySA+ CS0-003 exam can be taken at a Pearson VUE test center or via online proctoring. Both methods offer the full testing experience, but each has its own requirements and logistics.

Exam-Day Checklist

When you’re ready to take the CS0-003 exam, use this checklist to ensure you’re fully prepared:

You’ve consistently scored 80% or higher on Exam-Labs practice tests
You can identify alerts, logs, and vulnerabilities quickly
You’ve practiced at least 2 full-length exams in a timed environment
You can explain incident response steps in logical order
You know how to read outputs from Snort, Wireshark, and OpenVAS
You’ve reviewed communication strategies and how to write brief reports

Test-day logistics:

Ensure your Pearson VUE account is set up and verified
If testing online, check camera, internet, and system requirements
Get plenty of rest the night before and eat well before the test
Arrive early and have your ID ready

What to Do If You Don’t Pass

Even with preparation, some candidates don’t pass on their first attempt. The good news is that the CySA+ exam can be retaken without a long delay.

Steps if you need to retake:

Review your score report to identify weak domains
Spend 1–2 more weeks using Exam-Labs to reinforce those areas
Re-take practice exams to measure improvement
Consider joining a study group or online community for motivation

Remember, failing once is not uncommon in technical exams like CySA+. What matters is persistence and adjusting your study plan for the second round.
