This FAQ is intended to answer common security questions about the full Hyperfish product.
How Does Hyperfish read and write to my Directory?
- In a Cloud implementation (Azure Active Directory online only), Hyperfish connects directly to Azure Active Directory (AAD).
- In On-premises and Hybrid Active Directory (AD) deployments, Hyperfish analyzes the on-premises AD instance and considers this to be the source of truth. The synchronization cycle is completed when DirSync or Azure AD Connect synchronizes the AAD instance from the on-premises AD instance. Hyperfish analyzes/writes to on-premises AD in Hybrid configurations because not all properties are synced to AAD, and AAD does not necessarily write back properties to AD.
Which Active Directory objects and properties can Hyperfish modify?
- When writing to an on-premises Active Directory instance, the Hyperfish service runs as a service account. Hyperfish recommends using a least-privilege approach, delegating granular rights for specific properties in target AD containers.
How does Hyperfish secure the data sent between the on-premises Agent and the Hyperfish cloud service?
- Hyperfish secures all communication over HTTPS, a TCP/IP protocol used by Web servers to transfer web content securely. The data transferred is encrypted so that it cannot be read by anyone other than the recipient.
- Hyperfish also uses message queuing with AMQPS – or AMQP with TLS, a protocol that provides privacy and data integrity between two communicating applications. TLS is a widely deployed security protocol, used for any application that requires data to be securely interchanged over a network.
What kind of information is stored by Hyperfish, and for how long?
- In Cloud-only implementations, the User Principal Name and AAD Identifier for user objects are stored indefinitely.
- In Hybrid and On-premises implementations, the Object GUID and email address for user objects are stored indefinitely.
- User properties and analysis information are stored transactionally as Hyperfish does not require attribute details in order to calculate the overall completion statistics of a given directory.
- When a user submits profile information to be updated, the previous and new value are stored until the change is approved or rejected.
Where is Hyperfish data stored?
- All Hyperfish data is hosted in Azure. For more information about Azure security, please refer to the Microsoft Azure Security documentation: https://www.microsoft.com/en-us/trustcenter/Security/AzureSecurity
Who can access the Hyperfish Profile Update Page?
- The Hyperfish Profile Update Page is a self-service page which users can use to update their profile information. It can be accessed by navigating to https://app.hyperfish.com and logging in with O365 credentials.
- If profile information is missing or incomplete, users will be contacted through secure contact channels with a link to their Profile Update Page. This link is uniquely generated for the user, and expires after 30 days.
If there are service disruptions with Hyperfish, is any of my directory data lost?
- No - Hyperfish does not host any directory information. All information will repopulate as soon as service is restored. Additionally, all Hyperfish systems and data are made fully redundant. Daily backups are performed and point-in-time recovery is available.
