# Incapsula

- [Getting started](https://docs.hypersolutions.co/incapsula/getting-started.md): Incapsula (now Imperva) guards enterprise sites with the reese84 sensor and the \_\_\_utmvc cookie. This page explains how the pieces fit together.
- [Reese84](https://docs.hypersolutions.co/incapsula/reese84.md): Reese84 is Imperva / Incapsula's core bot check: a hidden JavaScript sensor that expects a signed payload before it issues a valid reese84 token.
- [Reese84 Dynamic](https://docs.hypersolutions.co/incapsula/reese84-dynamic.md): Reese84 Dynamic is used by sites that show a "Pardon Our Interruption" challenge page. Clients must solve the challenge and submit a valid payload to access the protected content.
- [Incapsula Captcha Block](https://docs.hypersolutions.co/incapsula/incapsula-captcha-block.md)
- [UTMVC](https://docs.hypersolutions.co/incapsula/utmvc.md): UTMVC is an Incapsula / Imperva protection that runs a script and sets a \_\_\_utmvc cookie (three underscores) before granting access to the site.
