The cloud is transforming modern IT infrastructure, driving innovation in cloud native applications and enabling hybrid workforces with flexible and secure access. Yet as cloud adoption grows, so does the attack surface. To meet these challenges, many organizations are embracing SASE (Secure Access Service Edge), a unified service model that seamlessly combines networking and security into a single framework.

However, one crucial aspect is often overlooked in the SASE conversation: strong key management. Encrypted traffic is only as secure as the keys that protect it. This is where Hardware Security Modules (HSMs) play a vital role. Whether deployed on premises or delivered as a cloud service, HSMs safeguard encryption and signing keys within certified, tamper resistant environments.

This white paper explores how HSMs strengthen SASE architectures, ensuring that the security perimeter extends all the way to the keys, because without protected keys, there is no true encryption.
