-## Expect-CT
-
-[Certificate Transparency](https://en.wikipedia.org/wiki/Certificate_Transparency) (CT) is a security standard that helps track and identify valid certificates, allowing identification of maliciously issued certificates.
-
-To configure reports in Sentry, you’ll need to configure the Expect-CT header from your server:
-
-
-```
-Expect-CT: ..., report-uri="https://___ORG_INGEST_DOMAIN___/api/___PROJECT_ID___/security/?sentry_key=___PUBLIC_KEY___"
-```
-
-For more information, see the article on [MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Expect-CT).
-
-## HTTP Public Key Pinning
-
-[HTTP Public Key Pinning](https://en.wikipedia.org/wiki/HTTP_Public_Key_Pinning) (HPKP) is a security feature that tells a web client to associate a specific cryptographic public key with a certain web server to decrease the risk of MITM attacks with forged certificates. It’s enforced by browser vendors, and Sentry supports capturing violations using the standard reporting hooks.
-
-To configure HPKP reports in Sentry, you’ll need to send a header from your server describing your policy and specify the authenticated Sentry endpoint:
-
-
-```
-Public-Key-Pins: ...; report-uri="https://___ORG_INGEST_DOMAIN___/api/___PROJECT_ID___/security/?sentry_key=___PUBLIC_KEY___"
-```
-
-For more information, see the article on [MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Public_Key_Pinning).
