+### Cypress Cloud Test Replay

+You may need to whitelist `capture.cypress.io` if you work with a strict VPN. See our FAQ section about [VPN subdomain whitelisting](/faq/questions/cloud-faq#Im-working-with-a-restrictive-VPN-Which-subdomains-do-I-have-to-allow-on-my-VPN-for-Cypress-Cloud-to-work-properly).
+
+You can [opt out](https://docs.cypress.io/guides/overview/why-cypress) of this feature in Cloud project-level settings.
