IT Security teams no longer focus solely on the perimeter of their networks when it comes to ensuring data security for their organisations. Most businesses have embraced the cloud, started to experiment with artificial intelligence, and deployed various security measures to comply with a range of regulations. These measures, which typically deploy cryptography to protect data, collectively introduce further challenges. We will discuss how to anticipate these challenges and take full control of the proliferation of cryptographic keys and certificates across a typical company's infrastructure. Taking control in this way is also the foundation for post-quantum readiness – we will explain why this is so important and how organisations can prepare.
