Hybrid work environments have introduced new vulnerable access points to organizations’ data and credentials, requiring improvements in credential security to help prevent the risk of cyber-attacks. In addition, the associated costs of security incidents that involve remote work are over $1 million more expensive on average than incidents that don’t involve remote work.1 Sixty-one percent of data breaches involve credentials, making them the most compromised data type in breaches.2 Cyber attackers often leverage compromised credentials to access personal data like medical history and banking information, which they can later sell on the “dark web.”
At Microsoft, our goal is to provide a built-in, intelligent, unified, and extensible solution to protect sensitive data across your digital estate – in Microsoft 365 cloud services, on-premises, third-party SaaS applications, and more. With Microsoft Purview Information Protection, we are building a unified set of capabilities for data classification, labeling, and protection not only in Office Apps, but also in other popular productivity services where information resides (e.g., SharePoint Online, Exchange Online, and Microsoft Teams), as well as endpoint devices.
There are currently over 250 pre-built Sensitive Information Types available (e.g., PII identifiers, social security, credit card, bank account numbers, etc.). We are pleased to announce that we are now starting public preview* of 42 new Sensitive Information Types (SITs) enabling organizations to identify, classify, and protect credentials found in documents across OneDrive, SharePoint, Teams, Office Web Apps, Outlook, Exchange Online, Defender for Cloud Apps, and Windows devices. These credential SITs can be included in information protection auto-labeling and data loss prevention policies to help organizations discover a wide range of digital authentication credential types (aka “secrets”), such as user credentials (username and passwords), default passwords, and Azure cloud resources (e.g., Storage Account Keys, SQL Server Connection Strings, and SAS). Also included are new SITs for Amazon S3 Client Secret Access Key, X.509 Certificate Private Key, GitHub Personal Access Token, ASP.NET Machine Key, Slack Access Token, Google API, Ansible Vault, and more. Note that many of these SITs are credentials that provide access to cloud development and other resources, which have been the target of sophisticated attacks on DevOps pipelines within organizations.
List of all 42 new SITs:

Azure Service Bus Shared Access Signature | Azure Redis Cache Connection String Password | Azure IoT Shared Access Key |

New credential SITs key capabilities
- Within the Microsoft Purview compliance portal, these new credential SITs can be added to auto-labeling and DLP policies to quickly and accurately detect and classify complex digital authentication credentials
- System administrators can test the accuracy of individual SITs against sample data
- These new credential SITs will be visible in Content Explorer and Activity Explorer, enabling users to:
- Locate documents that contain sensitive credentials within their environment
- Identify activity involving the use of credential data within their environment
Public preview also includes:
