Welcome back to the show! In this episode of the Razorwire podcast, I have the pleasure of discussing defence in depth with Razorthorn’s own illustrious consultants, Jamie Hayward and Tom Mills. During our conversation, we talked about the increasing number of tools and solutions available, the perils of ‘reactive’ budget allocation, as well as the changes we’re seeing in the industry and within our clients’ requirements. 

We also highlighted the need for a holistic approach to defence in depth, the importance of cyber threat intelligence, and the growing requirement for continuous security assurance.
