MongoDB has announced the general availability of MongoDB Queryable Encryption. This "first-of-its-kind" technology helps organisations protect sensitive data when it is queried and used on MongoDB. 
Data protection is the top priority among organisations across industries today as they face many regulations and compliance requirements to protect personally identifiable information (PII), personal health information (PHI), and other sensitive data. 

Organisations that work with highly sensitive data want to improve their security posture and meet compliance requirements by encrypting their data throughout its entire lifecycle, including while it is being queried. Until now, the only way to keep information encrypted during the entire lifecycle was to employ highly specialised teams with extensive expertise in cryptography.

Now with MongoDB Queryable Encryption, the risk of data exposure for organisations will be significantly reduced and will improve the productivity of the developers by providing built-in encryption capabilities for highly sensitive application workflows, such as searching employee records, processing financial transactions, or analysing medical records, with no cryptography expertise required.

The MongoDB Cryptography Research Group has developed this underlying encryption technology as a open source, hence many organisations can freely examine the cryptographic techniques and code behind the technology to help meet security and compliance requirements.

The general availability of MongoDB Queryable Encryption includes support for equality queries, with additional query types (e.g., range, prefix, suffix, and substring) generally available in upcoming releases.
