ONLYOFFICE respects the right of users to hold and control their personal data, and in the process of building products, ONLYOFFICE also places great emphasis on compliance with European laws.


HIPAA Compliance

The Healthcare Electronic Interchange Act (HIPAA) requires any organization conducting treatment, payment, and operational work in the healthcare sector, as well as business partners and subcontractors with access to any of their data assets, to protect sensitive patient data in accordance with a recognized set of standards. ONLYOFFICE will protect structured and unstructured data in static and transmission, provide access rights for data audit, provide Data integrity control, etc., to achieve the mandatory attributes defined by HIPAA and ensure that customer organizations fully comply with the Act. 


Access Control


Two factor authentication

In the era of electronic fraud and social engineering, everyone is vulnerable. Improve the security of portal login by moving SMS dynamic passwords. If a user improperly keeps their private password, the confidential data stored in the cloud or server by the user is likely to be easily accessed by third parties.


ONLYOFFICE integrates Clickatell, SMSC, and Twilio services, allowing users to find the SMS package that suits them regardless of team size and budget level. In addition, users can also enable dual factor authentication through code generation applications such as Google Authenticator, Authy, etc.


Single Sign-On (SSO)

By choosing single sign on based on traditional authentication, ONLYOFFICE will not store any login data for the user, and the user can store the data at a trusted global authentication service provider. ONLYOFFICE is a service provider (SP), while third-party applications are identity providers (IdP). Identity providers will verify user identities and carefully store login information to minimize the risk of unauthorized access to login data.


ONLYOFFICE integrates three IdPs to perform single sign on: Shibboleth, OneLogin, and AD FS。


Access Rights Management

With the expansion of business scale and changes in data classification, the threat of malicious internal behavior is also constantly expanding, so it is necessary to distinguish rights。


Users can easily divide user groups and levels in private portals. Portal modules and data access permissions can be set for each user or group to protect specific data from unnecessary attention and internal manipulation.。


Authentication filtering and monitoring

Customize login standards to allow specific frameworks for managing authentication based on your knowledge and concerns. In addition, all activities can be manually monitored and reported to detect potential fraud or harm.


Trusted mail domain. This option allows manual selection of the email server for registering emails. It also supports custom email domains.。

Remote Backup

Remote backup can reduce maintenance costs and save a lot of time, thereby achieving automated security processes. Users can manually or automatically backup data to the ONLYOFFICE document module, or store it in a location of their choice (DropBox, Box, Google cloud hard drive, OneDrive, etc.) or third-party services (AWS S3, Google Cloud Storage, Rackspace Cloud Storage, or Selectel Cloud Storage). If necessary, you can also use your own local driver for temporary manual backups。
