What is Nebula?

Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.

Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.

What is WorkOS?

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.

◆ Current state

Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.

◆ Where it's heading

The project has moved from single-IPv4-per-node assumptions toward a genuinely flexible addressing model, and the security fixes since v1.10.0 map directly onto that change — the new certificate features widened what the code has to validate. v1.11.0 shifts attention to the operational surface instead: structured logging, corrected firewall reject-versus-drop semantics, and Windows WFP filters installed by default.

◆ Prediction

The stated plan to assert low-s signature form when validating certificates is the concrete next step visible in these entries; expect it to land as a breaking validation change in a future release.

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

◆ Current state

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ Where it's heading

The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.

◆ Prediction

Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
