Discover how we keep your data secure

Private Cloud

Unlike most other cloud companies, ClassLink is your private cloud. We integrate with existing local networks and pass off authentication to your servers behind your firewall. We only keep enough data to identify your users in our system and only the groups specified by your administrators.

Everything is Encrypted

From your connection to our website, communication to our API servers and communication down to your local network, we use HTTPS/SSL for all communication. All our API calls require a temporary unique token that is assigned to your session and automatically deleted after you log off.

Secure Single Sign-Ons


ClassLink can create secure connections to existing ADFS and SAML authentication sources eliminating the need to exchange passwords.

AES 256 bit Encryption

Every single user has their own unique key for their data. Sensitive data is encrypted for all users with AES 256 bit encryption.

Deliver Windows Apps with Web Socket Secure

Easily and securely run Windows apps from any device with just one click. Our connections use either SSH or WSS (Web Socket Secure).


With OneRoster, your data is private and secure! Other data harvesting solutions collect IEP status, gender, race, social security numbers, birth dates and much more. We do not. We believe in full transparency related to the data we use to correlate your users to our My Classes module. No sensitive data is required and we don’t want it! Keep your private data where it belongs, in your SIS.

User Privacy

We do not harvest, resell or collect data beyond what is necessary to properly authenticate/identify users in our system. ClassLink is a premium enterprise service and does not rely on a “freemium” or ad supported model like many other cloud based solutions out there offering free services. This is your data, not ours. It will not be resold to anyone, ever.

Security Audits

We conduct regular security audits using third-party security firms to test and refine our protocols to ensure security and privacy. Our security audits evaluate both our core product platforms and our Application Programming Interface (API).

ClassLink has undergone the following security audits:

  • SOC 2 Type II – Report on Controls at a Service Organization Relevant to Security, Availability, Processing Integrity, Confidentiality or Privacy
  • CSA STAR – Rigorous third-party independent assessment of the security of a cloud service provider
