Our take
What our shortlists say about each one.
- 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.

- Varonis DSPM
Best for: Teams needing to see who can reach sensitive data
It earns its place on the access side of data security, since the graph answers who can reach a file, not only where the file sits. It runs in a hybrid model from SMB to enterprise, which suits estates with large on-premises file stores. Proofpoint has agreed to buy Varonis, so ask how licensing and the roadmap will change once the deal closes.
