A modern, elastic design for Burp Collaborator server

Summary: PortSwigger re-architected its public Burp Collaborator server from a monolith that stored data in RAM to a cloud-native, elastic design with multiple service instances behind load balancers and a Redis database. The change was driven by growth from roughly 8,000 Burp Suite Professional users in mid-2015 to over 60,000 in early 2022, plus 800 organizations using Burp Suite Enterprise Edition and a surge in traffic from Log4Shell scanning.

Key Takeaway: Collaborator interaction data is now encrypted at rest and requires both a user secret and a master secret to decrypt, with data deleted immediately after polling and purged as stale after 14 days - so the out-of-band findings your team relies on now sit behind a two-key decryption model rather than in server memory.
