Our take
What our shortlists say about the one we picked.
- IBM QRadar SIEM
Best for: Enterprises needing hybrid deployment with open detection rules
The trade-off is that QRadar's architecture feels heavier than cloud-native alternatives. Scaling it requires more infrastructure planning. IBM's acquisition history and product roadmap have also created uncertainty in the market, so if vendor stability is a factor in your evaluation, that's worth researching before signing a multi-year contract.
