- ConnectWise Automate: All versions prior to 2026.4

## Description

ConnectWise has released a security update for ConnectWise Automate™ that addresses a behavior in the ConnectWise Automate Solution Center where certain client-to-server communications could occur without transport-layer encryption. This could allow network‑based interception of Solution Center traffic in Automate deployments. The issue has been resolved in Automate 2026.4 by enforcing secure communication for affected Solution Center connections.
