Case Study: TransAlta achieves security investigations in minutes and $1M cost savings with Splunk

TransAlta Teams With Splunk for Security and Operational Intelligence

TransAlta, a power generation and wholesale energy marketing company operating in Canada, the U.S. and Australia, faced a slow, hard‑to‑use legacy SIEM that limited staffing, delayed security investigations, and couldn’t perform advanced event correlations—issues made more urgent by the need to scale and ensure reliable performance for a new high‑volume energy trading risk management platform.

After a two‑month proof of concept, TransAlta deployed Splunk Enterprise and Splunk Enterprise Security, quickly ingesting many more data sources and enabling advanced correlations with no formal training. The platform reduced investigation time from days to minutes, helped ensure on‑time delivery of the trading platform, produced up to $1M in cost savings, and improved visibility and operational intelligence across security, IT operations and DevOps.
