What our shortlists say about the one we picked.
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.
