Confidential computing is a security approach focusing on protecting data while it is being processed. Unlike traditional security measures that secure data at rest and in transit, confidential computing closes the gap by safeguarding data during computation. This is critical for maintaining privacy and security across various industries, especially where sensitive data is involved. As data breaches and cyber threats become more sophisticated, ensuring data remains encrypted throughout its lifecycle, including during processing, is vital. Confidential computing democratises secure computing by making high-level security accessible, leading to cost and energy savings, while enabling more secure data sharing. It's a pivotal advancement in data security, catering to the growing need for comprehensive privacy protection in our increasingly digital world.
