IPsec Add-on for PCF
Page last updated:
This guide describes the IPsec Add-on for PCF, which secures data transmissions inside Pivotal Cloud Foundry (PCF). Topics covered in this guide include IPsec Add-on for PCF installation and configuration, troubleshooting, and certificate rotation.
Your organization may require IPsec if you transmit sensitive data.
The IPsec Add-on for PCF provides security to the network layer of the OSI model with a strongSwan implementation of IPsec. The IPsec Add-on provides a strongSwan job to each BOSH-deployed virtual machine (VM).
IPsec encrypts IP data flow between hosts, between security gateways, and between security gateways and hosts. The IPsec Add-on for PCF secures network traffic within a Cloud Foundry deployment and provides internal system protection if a malicious actor breaches your firewall.

IPsec Add-on for PCF has the following limitations:
Due to a known issue in Windows Server OS, apps hosted on PAS for Windows cannot route traffic when deployed with the IPsec add-on for PCF.
Pivotal recommends configuring IPsec to use a self-signed certificate to sign instance certs. Using a certificate signed by a public or third-party CA is not recommended.
