What is Postmark?

Postmark adds its own SOC 2 Type 2 report to a run of security work.

Postmark's MCP server has 24 tools and delivery diagnostics, and the team has spent the autumn on account security: webhook verification and monitoring, IP Allowlisting for API sending, and 2FA on the free Developer plan. On November 5 it published its first standalone SOC 2 Type 2 report.

What is Wire?

Wire's web app is quietly moving conversations from Proteus to MLS encryption.

Wire's web client ships production tags every one to three weeks. The September release adds meeting reminders, better search for apps and people, and locale-aware dates, but its most consequential lines are about migrating conversations from the Proteus protocol to MLS: unread messages are preserved, read receipts are handled correctly afterwards, and MLS key-package recovery is more reliable. The October tag that followed is bare, with no notes.

Postmark vs Wire: editorial side-by-side

Postmark logo2.5

Postmark adds its own SOC 2 Type 2 report to a run of security work.

◆ Current state

Postmark's MCP server has 24 tools and delivery diagnostics, and the team has spent the autumn on account security: webhook verification and monitoring, IP Allowlisting for API sending, and 2FA on the free Developer plan. On November 5 it published its first standalone SOC 2 Type 2 report.

◆ Where it's heading

Postmark is pairing agent-facing tooling (Skills, the MCP server) with the compliance and security controls larger buyers ask for. The SOC 2 report removes a procurement blocker rather than adding a feature.

◆ Prediction

Expect more admin and compliance controls, such as audit logs or SSO, alongside further MCP server tools.

2.5

Wire's web app is quietly moving conversations from Proteus to MLS encryption.

◆ Current state

Wire's web client ships production tags every one to three weeks. The September release adds meeting reminders, better search for apps and people, and locale-aware dates, but its most consequential lines are about migrating conversations from the Proteus protocol to MLS: unread messages are preserved, read receipts are handled correctly afterwards, and MLS key-package recovery is more reliable. The October tag that followed is bare, with no notes.

◆ Where it's heading

The earlier window was about calling, with background effects and audio processing hardened over the summer. September's notes put the encryption protocol move front and centre, and the specific fixes suggest live conversations are already being migrated. Bare production tags still appear between documented releases, so roughly half the cadence is undocumented.

◆ Prediction

Expect more MLS migration fixes in the next documented release, since this one reads like the first wave of reported edge cases. Whether calling work resumes alongside is unclear from these entries.
