📌 The Short Answer
❓ The question readers are asking: "What's the difference between SIEM and log management, and which do I need?"
✅ The direct answer: Log management collects, stores, and searches log data to answer "what happened?" SIEM does all that plus real time correlation and alerting to answer "is this an attack?" EventGuard is the log management solution you need when SIEM is overkill with bloatware and a large price tag. The advantage to EventGuard is there are no costs after the low flat rate license.
📋 What is Log Management?
Log management is the practice of collecting, centralizing, storing, and searching log data from all your systems. Think of it as your IT infrastructure's memory. It helps you understand what happened on your servers, track failed logins across your environment, identify which machines are generating the most errors, and export logs for compliance audits.
EventGuard is log management. It is a complete Windows log management solution that gives you a centralized dashboard, a true single pane of glass for all your Windows event logs. EventGuard replaces the need for manual, server by server log checking with automated collection, instant search across all your machines, and long term retention for compliance.

🔒 What is SIEM?
SIEM (Security Information and Event Management) takes log management and adds real time correlation, advanced alerting, and threat detection. It watches what's happening right now and alerts you to suspicious patterns, such as potential brute force attacks, impossible travel logins, or security log tampering.
The problem with SIEM? SIEM solutions like Splunk, QRadar, and Sentinel come with enterprise price tags, often $50,000 to $500,000 or more annually, plus per gigabyte ingestion fees that spiral out of control. They also require dedicated security analysts to configure, tune, and maintain complex alerting rules. For most Windows environments, SIEM is overkill, too much bloatware and too high a price tag.

What is the difference between log management and SIEM?
Log management collects, stores, and searches log data to answer "what happened?" SIEM adds real time correlation and alerting to answer "is this an attack?" Most Windows environments need log management. Only organizations with dedicated security staff need SIEM.
Do I need a SIEM?
Probably not. Most Windows environments do not need SIEM's complex correlation and alerting. EventGuard gives you centralized Windows event log collection, live tailing for real time monitoring, compliance reporting for NIST 800 92, and Active Directory integration, all at a low flat rate with no ongoing costs.

How much does EventGuard cost compared to Splunk?
EventGuard uses low flat rate pricing with no per gigabyte ingestion fees and no per agent fees. Most customers save 70 to 90 percent compared to Splunk. A 100 server environment paying $100,000 or more annually for Splunk can switch to EventGuard for a fraction of that cost. See flat rate pricing →
