The short version

  • Only Ory Kratos has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ory Kratos headless means you build every screen, which is significant work compared with a hosted login page; Varonis Data Security Platform deployment is a project rather than an installation: collectors, service accounts, the initial crawl of a large file estate and behavioural baselining typically run for weeks to months before the first genuinely useful report, so value arrives well after the invoice does.
  • They diverge on capability: Ory Kratos covers Headless API, Varonis Data Security Platform covers Effective permissions modelling.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ory Kratos

  • Headless means you build every screen, which is significant work compared with a hosted login page
  • More moving parts than a monolithic IAM: Kratos handles identity, and OAuth2 needs Ory Hydra alongside
  • Documentation assumes real familiarity with identity concepts and is not a gentle introduction
  • Self-hosting identity carries the security and availability burden that hosted providers absorb

Varonis Data Security Platform

  • Deployment is a project rather than an installation: collectors, service accounts, the initial crawl of a large file estate and behavioural baselining typically run for weeks to months before the first genuinely useful report, so value arrives well after the invoice does.
  • The collection model requires granting the platform broad read access across the data you are trying to protect, which needs its own approval and creates a high-value target, and some change boards spend longer approving that access than approving the purchase.
  • Findings are produced far faster than remediation capacity: an initial scan routinely surfaces hundreds of thousands of overexposed objects, and fixing them means altering permissions owned by business units, so without an executive mandate it becomes a dashboard nobody acts on.
  • Licensing is driven by identity counts and connected data sources, so a directory full of stale accounts and service principals inflates the bill and every additional platform you connect adds cost, which quietly pushes organisations to leave their least-governed systems uncovered.
  • Coverage is deepest in the Microsoft estate and thinner elsewhere: connectors exist for other SaaS and database platforms but they do not all support the same classification, alerting and automated remediation, so a heterogeneous estate receives uneven protection at a uniform price.

Answered from the vendors’ own pages

Ory Kratos: Is Ory Kratos free?

Yes, open source and free to self-host. Ory Network is a paid managed service.

Varonis Data Security Platform: Is this data loss prevention?

No, and it is a common confusion. DLP watches data in motion and tries to stop it leaving. Varonis works on data at rest: where it is, who can reach it, and who touched it. They address different halves of the same problem and organisations frequently run both.

Ory Kratos: What does headless mean here?

Kratos provides identity flows as APIs and no user interface. You build the login, registration and recovery screens yourself.

Varonis Data Security Platform: On-premises or SaaS?

It is now sold principally as SaaS, with edge collectors deployed on your network to reach on-premises file shares and directories. Older on-premises deployments with Windows collectors and SQL Server still exist in the field and are being migrated.

Ory Kratos: Does Kratos do OAuth2?

No. Kratos handles user identity; OAuth2 and OpenID Connect provider functionality is Ory Hydra, a separate component.

Varonis Data Security Platform: Does it need agents on every server?

Generally no. It collects through APIs and network protocols with service accounts, with collectors deployed near the data rather than agents on every host. That is one reason deployment is less invasive than the scale of the data suggests.

Varonis Data Security Platform: How long until it is useful?

Expect weeks to a few months depending on the size of the file estate and how quickly the service accounts and access are approved. The classification and behavioural baselining both need time before the alerts mean anything.

Varonis Data Security Platform: Can it fix the problems it finds automatically?

Yes, it can remove global access groups, repair broken inheritance and quarantine exposed files under policy. Most organisations run this in simulation first, because automatically changing permissions on live business data goes wrong loudly.
