It is critical that everyone in the PostHog team follows these guidelines. We take people not following these rules very seriously - it can put the entire company and all of our users at risk if you do not.
Overview
We maintain a robust security program that follows best practice in order to meet the needs of our PostHog Cloud customers, making PostHog the ideal solution for customers who have GDPR, SOC 2, or CCPA obligations themselves. PostHog Cloud customers own the data they send to us for processing. We collect and analyze data about the use of PostHog Cloud by our customers, but that data does not include the user data that customers send to us to process on their behalf.
This page covers SOC 2, GDPR, and CCPA compliance.
Multi-factor authentication
We enforce the use of hardware security keys wherever we can. Every team members gets two of these, most commonly:
- One YubiKey 5C Nano for use with the work computer (can be left plugged in most of the time)
- One YubiKey 5C NFC for use with mobile devices, and as backup
Please enable security keys for Google Workspace, MacOS, AWS, 1Password (or whatever password manager you use) & GitHub at the very least. You can also use the Yubikeys to protect personal accounts. If you are new, please do this within your first month so you don't get locked out.
SOC 2
PostHog is certified as SOC 2 Type 1 compliant, following an external audit.
Our latest security report is publicly available (last updated April 2023).
Policies
We have a number of policies in place to support SOC 2 compliance. All team members have been invited to Drata to review these and to complete security training and background checks as part of onboarding.

GDPR
For the purposes of GDPR, customers use PostHog in one of two ways:
- PostHog Cloud
- Self-hosting a hobbyist PostHog instance
If a customer is using PostHog Cloud, then PostHog is acting as Data Processor and the customer is the Data Controller. We have some GDPR obligations to the customer's end users here.
If a customer is self-hosting PostHog then they are both the Data Processor and the Data Controller because they are responsible for their PostHog instance. We do not have access to any of their user data, so we do not have specific GDPR obligations to the customer's end users here.
PostHog's obligations as a Data Processor
We have reviewed our architecture, data flows and agreements to ensure that our platform is GDPR compliant. PostHog Cloud does not directly interact with our customers’ end users, nor does the platform automatically collect personal data. However, our customers might collect and send personal data to PostHog for processing.
PostHog does not require personally identifiable information or personal data to perform product analytics, and we provide extensive controls for customers wishing to minimize personal data collection from their end users. We provide separate guidance for our customers on how to use PostHog in a GDPR-compliant way in our Docs.
Technical and Organizational Measures ('TOMs')
- We maintain an extensive security policies to ensure we are managing data responsibly - see above.
- We enter into Data Processing Agreements ('DPAs') with PostHog Cloud customers when requested - our standard agreement is here. We maintain a register of all DPAs we have entered into.
- Customers can shoose whether to host data on our AWS server in the EU (Germany) or US. If data transfer is required from the United Kingdom, EU or EEA to our US-West based AWS environment, we rely on EU Standard Contractual Clauses (SCCs).
- We are registered with the Information Commissioner's Office in the United Kingdom as Hiberly Ltd., which is the legal name for our UK entity.
- A list of sub-Processors is maintained as part of our DPA - we keep this to a strict minimum.
- Our Data Processing Register is available for viewing by any interested party upon request.
Charles Cook (VP Operations) is our assigned Data Protection Officer and is responsible for overseeing compliance. Customers can email privacy@posthog.com for any questions relating to GDPR or privacy more generally.
CCPA
Under the California Consumer Privacy Act (CCPA), PostHog as a Service Provider to PostHog Cloud customers only. This is similar to the Processor definition under GDPR. We include a CCPA Addendum in our Privacy Policy.
We give all PostHog customers the tools to easily comply with their end users' requests under CCPA, including deletion of their data. We provide separate guidance for our customers on how to use PostHog in a CCPA-compliant way in our Docs.
We receive data collected by our customers from end-users and allow them to understand usage metrics of their products. We don't access customer end-user data unless instructed by a customer, and customer data is never sold to third parties. We do not have access to data collected by our customers who are using a self-hosted version of PostHog from end-users at all, unless they give us access to their instance.
