ExploreAbout this exam
Blue Team Level 1 (BTL1) is a practical, entry-level defensive cybersecurity certification from Centri (Security Team Training Ltd). It is built for security enthusiasts and professionals who want hands-on defensive skills, and the vendor positions it for students, IT personnel, security analysts, incident responders, threat intelligence analysts, and forensics analysts, with a recommended experience level of 0-2 years. The exam is a 24-hour practical incident response exam with immediate grading and feedback, and the syllabus spans Phishing Analysis, Threat Intelligence, Digital Forensics, Security Information and Event Monitoring, and Incident Response, taught alongside tools such as Splunk, Wireshark, Autopsy, Volatility, VirusTotal, MISP, TheHive5, and Sigma. Preparation is lab-driven: the purchase includes 4 months of on-demand access to 330+ lessons, videos, activities, and quizzes plus 23 browser labs with 100 hours of access, and the vendor strongly recommends completing every lab because they are designed to prepare you for the practical exam. The vendor states there is nothing in the exam that has not been covered in the course. The vendor reports that 70% of students pass on their first attempt and over 99% of students who use their free retake pass. Passing yields lifetime certification, digital and printed certificates, a Credly badge, and a challenge coin (gold for 90%+ on the first attempt).

What you'll study
About BTL1 preparation
What is the exam format?
It is a practical incident response exam delivered over a 24-hour window, with immediate grading and feedback. Rather than multiple-choice recall, it asks you to work through hands-on defensive tasks using a subset of the tools taught in the course, similar to a real incident response engagement. Detailed feedback is provided to help you improve.
How long does preparation take?
The vendor gives two figures: approximately 30 hours estimated time to complete on the course page, and typically between 40 and 50 hours in the FAQ. Actual time varies with prior knowledge, working speed, and available study hours. Plan for the higher end if you are new to blue team tooling.
Is there a free retake?
Yes. The price includes one free exam resit voucher, and additional resits can be purchased. The vendor reports that over 99% of students who use their free retake pass, so a first-attempt failure is not the end of the road. Detailed feedback from the first attempt helps target your revision.
What is included in the price?
The price includes 4 months of on-demand access to 330+ lessons, videos, activities, and quizzes, plus 23 browser labs providing 100 hours of access. It also includes the 24-hour practical exam with immediate grading and feedback, one free resit voucher, and on passing: lifetime certification, digital and printed certificates, a Credly badge, and a challenge coin.
What study order should I follow?
Work through the course in the order presented, since later modules build on earlier ones. Complete every lab rather than reading passively, because the labs are explicitly designed to prepare you for the practical exam. Give extra time to the five core domains: phishing analysis, threat intelligence, digital forensics, SIEM, and incident response.
What are common failure modes?
Skipping labs and relying on video watching is the biggest risk, since the exam is practical and the vendor warns there is nothing tested that the course does not cover. Other pitfalls include weak time management during the 24-hour window, unfamiliarity with the specific tools, and poor note-taking that slows investigation.
Are there entry requirements?
No. The vendor states there are no entry requirements for the exam and you can take it whenever you feel ready, though completing all the labs first is strongly recommended. The course is aimed primarily at entry-level and junior roles, with a recommended experience level of 0-2 years.
How much does it cost and are discounts available?
Training and exam price is listed at £399.00 GBP, with VAT invoices only available through the corporate sales team. A 10% discount is available to verified students actively studying at an established educational institute, and discounts also exist for military personnel, first responders, and veterans. Corporate discounts depend on license volume.
What rewards come with passing?
Certification is for life. You receive a digital PDF certificate, a printed certificate, a Credly digital badge, and a challenge coin. The coin is silver by default and gold if you score 90% or higher on your first attempt, which gives strong candidates an extra incentive to prepare thoroughly before sitting the exam.
