Graylog vs IBM QRadar

Graylog and IBM QRadar are both open source siem solutions. Graylog open-source log management and SIEM platform with intuitive analytics, while IBM QRadar aI-powered enterprise SIEM with automated threat detection and investigation. The best choice depends on your organization's size, technical requirements, and budget.

Choose Graylog if open-source core with generous free tier is your priority and teams needing cost-effective log management with SIEM capabilities and an intuitive user experience. Choose IBM QRadar if strong out-of-the-box threat detection matters most and large enterprises needing an AI-augmented SIEM with strong compliance reporting and network flow analysis.

IBM QRadar starts at From $800/month (100 EPS) / Enterprise custom (events per second (eps) or flows per minute). Graylog starts at Free (Open) / From $1,250/month (Operations) / Security custom (per-node licensing (operations and security tiers)). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply Graylog is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether IBM QRadar supports importing your existing configs or policies. That's usually the biggest time sink.
