Some feedback from our clients.

People are at the centre of digital product security. Our approach means we work directly with the people making decisions, building and infuencing product development.

We love to work with these teams and we love to hear from them as to how they've found working with us. Here are some examples of the feedback we get from teams across our clients' organisations.


I like how you tied back Security to the four metrics metrics in Accelerate as well as SRE principles, that was very clear. I was actually already planning to recommend you to some people in my network :)

SRE Energy Sector
Engineering Foundations Course

[Practioner] clearly has a wealth of expertise in application security, and uses this very effectively to provide a highly informative course that includes insights and recommendations specific to our business domain. I am confident that other business domains would be equally served due to [Practitioner]'s range of experience.

Engineering Medical Equipment & Devices Sector
Decision Makers Foundations Course

The hands on sessions of seeing an issue and then fixing it in the code really brought it to life. Letting us do the fixing rather than watching keeps you involved, I thought the site was excellent

Secure Coding Workshop

[Practitioner]'s knowledge and experience is exceptional. I really liked the Case Studies. I could always use more.
