# Salem Automation > Salem Automation modernizes mission-critical legacy systems for industrial and enterprise operations. We bring dual fluency in legacy platform emulation (OpenVMS, VAX, Alpha) and industrial automation (PLC, SCADA, and control systems), helping organizations keep proven systems running reliably while charting a clear path to modern infrastructure. Salem Automation has more than 30 years of system-integration experience serving manufacturing, aerospace, defense, energy, government, and other regulated operators. Our work covers the full modernization path: supporting and emulating legacy hardware, modernizing legacy applications and databases, and migrating workloads to modern platforms. In industrial environments we operate at ISA-95 Levels 2-4, modernizing and replacing supervisory control, SCADA, and HMI systems. Our emulation products include vtVAX, vtAlpha, and vtServer. Salem is a member of the IT Service Alliance (ITSA). ## Services - [Services Overview](https://www.salemautomation.com/services/): The full range of Salem's legacy modernization, emulation, database, support, and industrial automation services. -
