Modern Cybersecurity: Post Pandemic Review Of Defence in Depth

Welcome to the Razorwire podcast, where we explore the latest trends and insights in the world of cybersecurity.

In this episode, we delve into the topic of defence in the post pandemic world with our esteemed guests, Jonathan Care and Christopher Fielder. We talked about why it’s more important than ever for organisations to adequately adapt their cybersecurity capabilities to meet the requirements of remote working and why it’s essential to have multiple layers of security to detect and respond to threats before they reach critical endpoints. 

During our conversation, we discussed the importance of due diligence when considering a cloud-first approach or involving a detailed supply chain. We also highlighted the challenges faced by security teams and departments during the pandemic, as well as the rise of ransomware groups and the use of AI in cybersecurity. 

"The pandemic has really shown that we need to be more agile and more adaptable."
