Case Study: Allegro MicroSystems strengthens IT and OT visibility with Armis

Global Semiconductor Company Uncovers Thousands of Networked Devices

Allegro MicroSystems, a global semiconductor leader, needed better protection for high-value intellectual property across its cloud environment and far greater visibility into devices connecting to its IT and OT networks. The company was especially concerned about ransomware, data breaches, and unmanaged personal devices in overseas manufacturing facilities. To address these risks, Allegro MicroSystems chose Armis as an additional layer of defense for its corporate estate.

Armis provided agentless, unified asset visibility and security across IT and OT, giving Allegro MicroSystems a single pane of glass for discovering managed, unmanaged, and personal devices, identifying vulnerabilities, and improving policy enforcement. With Armis, the team uncovered rogue devices, vulnerable PLCs, and even overlooked expired software certificates, while also gaining easier incident response and board-level security reporting. The result was stronger protection, better operational oversight, and immediate time-to-value from the deployment of Armis.
