Most organisations are using multiple cloud services, not just one, and using a mix of public, private, and hybrid clouds. These cloud services are handling increasing quantities of sensitive data generated by fast-moving technologies such as Internet of Things (IoT), digital transformation, and digital payments. This brings heightened risk due to the sensitive nature of the data, enormous volumes, ceding of partial control to cloud vendors, and tighter regulations for privacy and security. Encryption, with strong encryption key management, is the best protection for sensitive data. Hardware Security Modules (HSMs) are crucial, providing certified, hardened, tamper-resistant environments to ensure the trust, integrity and control critical to securing business applications. With BYOK you can bring your own keys to your cloud application, giving you full control over your data. High-assurance HSMs let you benefit from the flexibility and economy of cloud services while strengthening your key management practices.
