Distinguishing attributes of OSIsoft include its deep specialization in operational technology data management and its longstanding reputation for reliability in mission‑critical environments. The PI System is recognized for its ability to handle high‑volume time‑series data while providing low‑latency access for analytics and visualization.

In November 2018, the company experienced a significant cybersecurity breach in which attackers compromised domain accounts across 29 computers and 135 user accounts, exposing credentials and prompting a forced reset of passwords and accelerated multi‑factor authentication deployment. The incident highlighted the importance of securing credential stores and led OSIsoft to strengthen its internal security controls while working with external partners to investigate the scope. Although the breach did not alter the company's core product offerings, it underscored the challenges faced by industrial software providers in protecting both their own infrastructure and the sensitive data of their clients.
