What is Pacemaker?

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

What is WorkOS?

WorkOS is making agents first-class principals and taking custody of the tokens they act with.

WorkOS shipped a dense two-week window across three fronts. On identity, Agent Registration lets agents sign into AuthKit using the auth.md protocol, treating a non-human caller as a registrable principal rather than a service account borrowed from a human. On integrations, Pipes gained API key support alongside OAuth and then a Token Proxy that calls third-party APIs on a user's behalf without the application ever handling their access token. Separately the company launched Atlas, a Slack-based AI coworker, and shipped a local WorkOS API for CI/CD testing with seeded data, signed webhooks and fault injection.

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

◆ Current state

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

◆ Where it's heading

The cluster's internal transport is being rebuilt on the assumption that the network between nodes is not trusted. Authentication and encryption arrived first, and the fixes that followed, overflow guards and a maximum remote message size, are the hardening pass on the same code paths. Release discipline is heavy and visible: each version ships a release candidate with an identical commit set days earlier, and every 3.0 release documents the regressions it introduced and where they were fixed.

◆ Prediction

Remote CIB operations now support both X509 certificates and PSK, and the recent fixes all sit in message framing and size limits; further work is most likely to continue in that message-handling code rather than adding another authentication mechanism.

WorkOS is making agents first-class principals and taking custody of the tokens they act with.

◆ Current state

WorkOS shipped a dense two-week window across three fronts. On identity, Agent Registration lets agents sign into AuthKit using the auth.md protocol, treating a non-human caller as a registrable principal rather than a service account borrowed from a human. On integrations, Pipes gained API key support alongside OAuth and then a Token Proxy that calls third-party APIs on a user's behalf without the application ever handling their access token. Separately the company launched Atlas, a Slack-based AI coworker, and shipped a local WorkOS API for CI/CD testing with seeded data, signed webhooks and fault injection.

◆ Where it's heading

The through-line is that WorkOS is building the plumbing for software that acts on a user's behalf without inheriting the user's credentials. Agent Registration establishes who the agent is, the Pipes Token Proxy removes the need for the agent's application to hold the token it acts with, and the one-click Claude and ChatGPT plugins put those pieces in reach of the tools people are already using. Atlas points a second way: WorkOS is not only selling this infrastructure but building an end-user product on top of it. The CI/CD testing work is the unglamorous prerequisite for any of it being adopted in regulated environments.

◆ Prediction

Expect the agent principal from Agent Registration and the token custody in Pipes to converge, so that an agent's registered identity is what scopes which third-party calls the proxy will make for it. Whether WorkOS competes with its own customers via Atlas is the open question these entries do not answer.
