A SIEM can start collecting logs quickly. Proving value is harder.
According to the 2025 SANS SOC Survey, 42% of SOCs dump all incoming data into a SIEM, often without a retrieval or management plan. That is how many SIEM programs turn into expensive data repositories instead of engines for faster detection and response.
This guide shows what buyers should realistically expect after deployment, from early visibility wins to tuned detections, cleaner investigations, and measurable SOC outcomes. It also highlights where platforms like NetWitness SIEM can help teams move beyond log collection and turn security data into actionable intelligence.
What You'll Learn:
- Why should the SIEM value not be measured by log volume alone?
- What should security teams expect in the first 30 days of deployment?
- How SIEM programs should mature to meaningful detection by day 60.
- Which metrics prove SIEM value by day 90?
- The red flags that suggest your SIEM is creating more noise than outcomes.
- How NetWitness SIEM supports faster detection, stronger context, and smarter investigations.
