Case Study: Leading IT Security Provider achieves dramatic cybersecurity visibility and rapid threat detection with OpenText

IT firm uses Micro Focus ArcSight to dramatically improve cybersecurity visibility for telecommunications company

An anonymous IT security provider that builds cybersecurity solutions for banks, manufacturers and other large organizations was engaged by a major telecommunications customer struggling to monitor a sprawling, rapidly growing IT estate. The telco faced thousands of devices and custom applications, bureaucratic barriers to log access, slow manual log ingestion and analysis, and even a failed PCI-DSS audit — leaving it exposed to breaches and unable to respond quickly to incidents.

After a yearlong proof of concept the telco implemented Micro Focus ArcSight ESM to centralize log collection and automate analysis, connecting more than 2,000 systems (including in‑house apps) and enabling customizable use‑case rules for more accurate alerts. ArcSight simplified and sped up detection — uncovering a previously unseen vulnerability during testing — reduced time to detect and respond to threats, eased compliance efforts, and saved staff hours of manual work.
