OSIsoft LLC

Profile narrative

OSIsoft LLC, also known as OSIsoft, was a United States-based software company best known for the PI System, a platform for collecting, storing, contextualizing, and delivering time-series operational data from industrial processes. Its technology connected data from sensors, control systems, and other operational sources to applications and users that needed near-real-time visibility into plant and infrastructure performance. The company’s work sat in industrial software and operational technology data management rather than general-purpose business software. Its customers were typically in asset-intensive sectors such as power and utilities, oil and gas, chemicals, mining, pharmaceuticals, manufacturing, water and wastewater, and other environments where continuous process data had operational value.

The PI System’s distinguishing attribute was its focus on high-volume, time-series data generated by physical operations. Instead of serving primarily as an enterprise application vendor, OSIsoft specialized in infrastructure for operational data historians, event data, and integration between plant-floor systems and higher-level analytics or monitoring tools. This positioned the company within the industrial automation and industrial IT ecosystem, where reliable capture and long-term retention of process data are used for operations, engineering, maintenance, and performance analysis. The company had an international footprint, with its software used across large industrial organizations and critical infrastructure environments.

OSIsoft was headquartered in the United States. The company became part of AVEVA after AVEVA acquired OSIsoft, and OSIsoft’s products and brand were incorporated into AVEVA’s industrial software portfolio. This ownership change placed OSIsoft’s technology within a broader industrial software group focused on engineering, operations, and performance software for asset-intensive industries.

A notable public security incident occurred in 2018, when OSIsoft reported a breach affecting its domain environment. The company stated that attackers stole credentials from 29 computers and 135 accounts and that it treated all domain accounts as potentially compromised. The exposed credentials included those associated with employees, consultants, interns, and contractors, along with email addresses and passwords. The incident led OSIsoft to accelerate multi-factor authentication deployment and to warn about password reuse because stolen credentials could create risks beyond the company’s own systems.
