MongoDB Atlas is enhancing its encryption capabilities to meet evolving security challenges and compliance requirements, with significant upgrades including improved customer-managed key (CMK) functionality and support for TLS 1.3. These enhancements allow enterprises to have full control over their encryption keys, ensuring data protection at rest, in transit, and in use. CMK management over private networking is introduced, eliminating the need for public IP exposure and simplifying network management. As TLS 1.3 becomes the standard, older versions are being deprecated to meet modern security standards, and custom cipher suite selection offers greater control over cryptographic configurations. Additionally, Queryable Encryption allows secure queries on encrypted data without exposing plaintext, aligning with MongoDB's commitment to providing robust, enterprise-grade security solutions that adapt to changing threat and regulatory landscapes.
