CloudMask is a data security company that offers Dynamic Data Masking (DDM) technology, which masks sensitive data — both structured and unstructured — in real-time at the endpoint level. The core premise of the company is that data breaches are inevitable, but data exposure is not; rather than focusing solely on perimeter defense to keep attackers out, CloudMask's approach centers on rendering intercepted data useless to unauthorized parties. The company's patented technology runs on end devices, where it transparently intercepts and transforms production data before it reaches unauthorized requesters, without making physical changes to the original data at rest. This allows organizations to use SaaS and legacy applications — including Google Workspace, Salesforce, and Microsoft 365 — without exposing sensitive information to cloud providers, administrators, or malicious actors who may gain access. CloudMask's platform incorporates encryption with integrated key management, data access policies including privileged user controls, security intelligence for monitoring protected data access, policy management automation, and multi-tenancy features. The solution is designed for businesses, enterprises, and SaaS developers, with vertical focus on legal, financial, healthcare, and education sectors. The company also operates a Cloud Partner Program open to IaaS/PaaS providers, SaaS providers, MSPs, MSSPs, and enterprises. CloudMask has received endorsement from 26 government cybersecurity agencies globally and counts partners such as IBM, Salesforce, Amazon, and Entrust among its ecosystem. The company is headquartered in Canada.
