The short version

  • Only ESLint has a free tier, so it costs nothing to try first.
  • Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; 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.
  • 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.

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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

ESLint: Does ESLint automatically fix code issues?

Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.

Source
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.

ESLint: How much does ESLint cost?

ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.

Source
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.

ESLint: Can I write custom ESLint rules?

Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.

Source
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.
