The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; 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.

Where each one falls short

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

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

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

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

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.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

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.

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.
