“This is one of the best training I’ve done regardless of price or location. This was a fantastic training especially in terms of the quality of the labs. I’ve done a lot of different InfoSec trainings and the labs are usually a little haphazard. The labs in this training were structured in a way, we could take this data and the labs themselves and keep working on the concepts discussed.”

“The class really exceeded my expectations. I was expecting the course to be too basic but after getting some hands-on practice with the material I think it was really worth it in fact I felt the class enhanced the skills I already had. I’m taking away a lot of new techniques, new material which I can embed into my company. The trainer has been really great.”

“There was a lot of new information that we probably wouldn’t have come across in our organisations. It will be very useful to see how we can implement all the information We learnt how to improve our processes and DevSecOps pipeline. And it was really good to see it done in a light-weight and fast manner to keep up with the demands of the agile development.” 

“They enabled us to develop a thorough threat modeling process that can be applied to internal and external networks. we45’s training was a 10x multiplier for us, allowing our team to easily build models the SOC can use to better understand relevant threats and equip network and application owners with the information they need to prioritize and mitigate risks.”

“This training showed me the different ways in which different elements like threat modelling and automation testing go together. The class opened my eyes in terms of what is coming to security automation in the next 2-3 years. I think application of automation is very important with everything moving so fast. I’m going to learn and implement what I learnt from this class.”
