What Drives On-Premise eDiscovery Review Costs
The production deadline is set. Then another round of custodian data is added to the case, more people need to review it, and the case stays open longer than expected. You still need to find what matters and get the production out. You also need to explain what the additional work will cost.
Choosing between cloud and on-premise review starts there. The useful question is not which option has the lowest advertised price. It is what each option will cost for your matters, your team, and the time your data needs to remain available.
What drives the cost of cloud review?
SaaS eDiscovery review costs can change as a matter grows. Depending on the agreement, you may pay hosting fees in several ways: by data volume per month, processing, user access, or added capabilities.
The Winter 2026 eDiscovery Pricing Survey analysis, published by ComplexDiscovery in partnership with EDRM, offers useful benchmarks. For basic hosting without analytics, 54.7% of respondents reported prices below $10 per GB per month. For hosting with analytics, 32.1% reported prices between $15 and $25 per GB per month. These are survey responses, not a quote for your matter.
A monthly rate may be easy to budget for at the start. The total changes when more data arrives, several matters run at once, or a case remains hosted after active review slows down. Ask what happens to the bill in each of those situations before you choose a platform.
What drives the cost of on-premise review?
With on-premise review, your organization runs the platform in its own environment and controls how case data is hosted. Law firms and legal service providers can charge clients for hosting and build a potential source of revenue. Your software and infrastructure costs remain in your hands, giving you more control over how you price review services and manage your margins. To understand the full financial picture, budget for the infrastructure and ongoing support your expected caseload will require.
That gives you a different way to plan costs, especially if your team handles a steady volume of matters, keeps data for a long time or has low economic cases with high data volumes. It also means checking whether your infrastructure has room for a large new collection or several reviews at once where budgets are tight on those cases.
Get the full on-premise estimate in writing. Ask what the license covers annually, how access is priced, who maintains the environment, and what it will cost to add capacity. Those answers matter more than a comparison of hosting fees alone.
Where can an eDiscovery case budget change unexpectedly?
Processing. In the Winter 2026 survey, 73.6% of respondents reported ingestion-stage processing prices below $75 per GB. Prices measured at completion, after data has been prepared for review, covered a wider range. Ask vendors which volume they use to calculate a processing charge and when they measure it.
Reviewer access. The survey found that 41.5% of respondents reported fees between $50 and $100 per user per month for access to hosted data; 34.0% reported alternative pricing models. Those results show why access terms deserve attention, but they do not describe CloudNine Review On-Premise licensing. For each platform you consider, ask how the price changes if more attorneys or paralegals need to join a matter.
What hosting includes. Basic hosting and hosting with analytics had different price ranges in the survey. Check which search, review, and support capabilities are included in each proposal. A lower per-GB figure does not tell you the full cost of getting a dataset ready for production.
When could on-premise review cost less?
Compare the options over the same period and for the same expected work. Estimate your cloud hosting charges across active and retained matters. Then add up the full on-premise cost: software, infrastructure, maintenance, staffing, and expected services.
If projected cloud hosting charges alone exceed that full on-premise total, on-premise costs less under those assumptions, even before you count other cloud charges. If they do not, you need to compare the remaining costs on both sides before drawing a conclusion.
Run the numbers for a normal workload and for a demanding one. Add the custodian who arrives late, the larger dataset, and the case that stays open. That is how you find out whether the budget will still make sense when the matter changes.
What if your organization needs to keep data in its own environment?
Cost may be only one part of the decision. Your client, agency, or internal policy may require greater control over where case data resides and who can access it. On-premise deployment gives your organization an option to manage the review environment within its own infrastructure.
For public sector buyers, there are on-premise eDiscovery platform options available through Carahsoft and its reseller partners. CloudNine also identifies NASPO ValuePoint and OMNIA Partners contract routes; your procurement team can confirm which route applies to your agency.
How do you choose a review model your team can work with?
Start with the case, not the deployment label. Your paralegals and attorneys need to bring data together, search it, review it, and produce it by the deadline. They may need help when the work becomes complicated, and they definitely need a cost they can explain to the client.
For any of these considerations, CloudNine has created educational content that can help on your journey and our teams can consult with you on what can work best for your situation even if it is continuously changing. If you would like to see the technology behind the discussion, request a demo and bring your matter count, data volumes, current hosting spend, access requirements, and expected retention periods. We can compare the options against the work you actually have to do. If you don’t have any of that information, that is fine too!
