BLT1 PRACTICAL INCIDENT RESPONSE EXAM
Students are able to start their practical 24-hour incident response exam immediately from the BTL1 course within 12 months of purchase. Students will have access to a cloud lab via an in-browser session for up to 24 hours and must complete answer 24 task-based questions. This forces candidates to use different tools, investigate different systems, and identify activity across multiple ATT&CK Framework tactics.
Once the student has answered all the questions they can, they are able to submit the exam to receive immediate grading and feedback. 70% is required to pass and earn the silver challenge coin, while 90% (on the first attempt) is required for the gold challenge coin.
If a student fails the exam they will be permitted one free resit voucher which must be used within 12 months of purchase. Additional resit vouchers can be purchased for £100. Students are not permitted to resit their exam within 10 days of failing.

PRACTICAL INTRUSION ANALYSIS EXAM
The BTL2 exam is designed to practically assess students on the four domains covered in the training course by utilising a range of tools and techniques to investigate a realistic intrusion scenario. Students have access to the exam lab for up to 72 hours, and must submit their written report, based on a provided template, within this timeframe. The report has pre-built sections for items such as an executive summary, indicator list, malware analysis conducted, and investigation steps per system within the network.
After submitting the report, it is hand-marked by our instructors within 30 working days (but typically much quicker). Students must earn a 70% score or higher to pass, and a 90% score or higher on their first attempt to earn the gold BTL2 challenge coin.
