SOC 2Dedication to ensuring our user’s security and confidentiality while utilizing COS services is a top priority. One way we do this is by publishing our practices in our Account and Security Page

Additionally, in 2023 we sought out SOC2 (Service Organization Control Type 2) accreditation. By obtaining a favorable SOC2 report from the Moore Group, CPA we aim to provide confidence for our users and partners through continued third party auditor attestation.

The SOC2 accreditation program is maintained by the AICPA (American Institute of Certified Public Accountants). Please do reach out to support@cos.io for any questions.

COS has been very fortunate to receive increasing sponsorship each subsequent year, and has used these new investments to grow programs and operations in pursuit of our mission. Our community has responded enthusiastically to new tools and services and we are now pursuing strategies to sustain these services as public goods.
