A Fortune 500 energy firm closed its security blind spots, without betting on a single vendor
A leading independent oil and gas producer replaced a failing custom-built SIEM with a hybrid solution pairing Splunk and Exabeam, giving the security team full visibility across Azure and three on-premise data centers.
THE OUTCOME
A leading independent oil and gas producer replaced a failing custom-built SIEM with a hybrid solution pairing Splunk and Exabeam, giving the security team full visibility across Azure and three on-premise data centers, faster threat detection, and automated response workflows, without locking the firm into a single vendor.
HOW THEY GOT THERE
Presidio assessed the full IT environment and ran structured proof-of-concept tests on the two strongest SIEM candidates. Splunk proved superior for high-performance log management. Exabeam for behavioral threat detection and ease of management. Rather than choosing, Presidio recommended running both, they integrate cleanly and cover each other’s gaps.
WHY IT WORKED
The IT team was treating SIEM selection as a binary decision. Presidio’s vendor-agnostic approach reframed the question. Exabeam captures full incident context fast; Splunk pinpoints cause and scope through log correlation. Together they compress detection-to-containment time and both connect to the firm’s existing Phantom SOAR platform.
