Compliance and Assurance

Sigma adheres to global privacy laws and security standards with measures in place to help our customer compliance requirements. The following is the current list of reports available to all customers and prospects under NDA. Kindly reach out to your account team for copies of reports as applicable to your organization.

General Data Protection Regulation (GDPR)

At Sigma, we firmly support GDPR in both practice and philosophy.  We work with our customers in the European Economic Area to assure compliance with personal data handling requirements and cross-border transfer requirements under GDPR.

As a processor, we process data on behalf of our customers.  We expect that some of our customers will require us to enter into a data processing addendum (“DPA”), per Article 28 of GDPR.

Sigma uses several subprocessors, but the majority of our obligations hinge on our primary subprocessor: Google Cloud Platform. Read more about Google Cloud Platform’s commitment to GDPR here. And for a full list of our subprocessors, click here.

California Consumer Privacy Act ( CCPA )

Sigma will support any removal request from any state/country as long as it is valid and made by a qualified party.

For information on how to exercise your rights or if you are an authorized agent wishing to exercise rights on behalf of a California resident, please use this link.

Health Insurance Portability and Accountability Act (HIPAA)

Sigma has completed a Health Insurance Portability and Accountability Act (HIPAA) third-party attestation. This assures that Sigma has a HIPAA compliance program with proper controls in place for safeguarding protected health information (PHI). Sigma will sign a Business Associate Agreement (BAA) with our healthcare customers.

SOC 1 Type II

Sigma has completed a SOC 1 Type II report to validate our process and controls around financial reporting. This ensures that our customers can have confidence in Sigma and our platform for many years to come.

SOC2 Type II

Sigma leverages best practices for security controls as part of our data security program. We work with AICPA-certified, third-party auditors to evaluate our information security system controls.


Sigma maintains a SOC 3 report which is the public report of security controls. It is a summarized version of the SOC 2 report and provides validation that Sigma has completed an independent third-party audit against the AICPA’s Security Trust Principles.
