"The session was really engaging and I learnt a lot around attack & defence techniques during the day. The labs for all environments were very easy to use, and the presenter Jonathan was very well spoken and supportive at all times."

"I came from a non-networking background, so I have very limited knowledge, however, I have learnt a lot in terms of networking and understanding new cyber security protocol. Expecting to score no points, I think being able to complete the main purpose of lab and score points shows how much I picked up."

"Jonathan's training was very well structured and highly accessible. The hands-on labs were challenging but satisfying, and the scoring system and dashboard were easy to use. The presentation aspect of the training was concise but thoughtfully planned, and Jonathan was open and responsive to questions from participants throughout. The training delivered though this session was a good mix of book knowledge and practical skills, and the labs provided a good consolidation. Jonathan engaged with all participants and ensured that no one was left behind, and gave time to everyone while keeping tabs on progress though the exercise. The course resources are well made, and well suited to the scenario and purpose."

"Jonathan was someone I have worked with before and knew his skill set. He was able to come into our offices in London, and support me in fixing a long running issue with our WiFi, and our conference room technologies. I'm sure there will be more work for him in the near future. Jonathan is professional in his work ethic and friendly. Thanks."

"Jonathan delivered a really engaging and practical session on honeypots. I appreciated how he explained the fundamentals clearly before diving into real-world research across multiple countries and comparing trends over time.
The data-driven insights, especially around common attack patterns and password trends, were genuinely interesting and gave useful context to how honeypots can support detection and threat intelligence strategies.
A well-structured talk with solid technical depth, but accessible for a broad security audience."
Bogdan, Security Researcher, attendee
(Talk on honeypots, January 2026.)
⭐⭐⭐⭐⭐
"Jonathan is an excellent teacher and speaker, and really knows the technology. He also clearly has the breadth of experience to add huge contextual value to that knowledge. Jonathan is also approachable, engages with the audience, and adjusts his approach according to their level, so everyone took away the maximum out of the session. He educated and entertained, adding a relevant, practical element that solidified the concepts he discussed. Jonathan's training ticked all the boxes for effective learning."
