NetDocuments is the better fit for firms that want a legal-grade document system delivered entirely as a cloud service, while iManage Work suits midsize and large firms that want deep matter workspaces, granular security policies, and a choice between running the software themselves or in the iManage cloud. Both are matter-centric systems built for law firms, both file email from Outlook, and both quote prices on request. The decision usually turns on deployment, firm size, and how much administration you can support.

NetDocuments ranks first and iManage Work second in our ranking of the best legal document management software. Below, we compare them head to head on the issues that decide most DMS projects.

Deployment and administration

NetDocuments has always been cloud-only. There are no servers to buy, patch, or back up, and upgrades arrive from the vendor. For firms without a large IT team, that removes a major source of cost and risk.

iManage Work grew up as on-premises software and now runs either on a firm’s own servers or in iManage Cloud. Cloud users reach iManage Work through a single endpoint and are routed to the nearest data center. The flexibility appeals to large firms with existing infrastructure or clients that set strict hosting rules, and it lets them move to the cloud on their own timeline.

Winner: NetDocuments for most firms, because the cloud-only model means less to manage. iManage wins for firms that need on-premises as an option.

Document and email management

On core document work, the two products are close. NetDocuments files documents and email by matter and works inside Microsoft Office and Outlook. iManage Work organizes everything in client and matter workspaces, files email from Outlook, and keeps version control on every document.

iManage’s workspace model is especially deep, which is why many large firms run on it. Practice groups can set up templates for each matter type, with standard folders and profile fields. NetDocuments covers the same ground with a structure that smaller firms tend to find easier to adopt.

Whichever you trial, ask an attorney to file an email thread and its attachments to a matter, then find a specific clause across a practice group. Filing speed decides whether the matter file stays complete.

Winner: iManage Work for depth of workspace organization at scale. NetDocuments is easier to adopt for smaller teams.

Security and compliance

Both products are built for client confidentiality, and both offer ethical walls, audit trails, and detailed access controls. The differences are in emphasis.

NetDocuments says it applies three layers of encryption automatically and lets customers replace one with customer-managed keys for two-party encryption. Administrators can define where documents are stored by country or region and set geo-aware rules that grant or block access based on a user’s location. The company says its platform meets standards including FedRAMP, GDPR, and HIPAA.

iManage offers detailed security policies within Work, and sells dedicated security products, Security Policy Manager and Threat Manager, for firms that want centralized need-to-know access rules and monitoring for unusual behavior. That layered approach fits large firms with security teams and demanding corporate clients.

Winner: Tie. NetDocuments stands out on encryption key control and data residency in the cloud, while iManage stands out on centralized policy management and threat monitoring for large firms.

AI features

Both vendors now build AI into their platforms. NetDocuments offers an AI assistant and prebuilt legal apps for search and review. iManage offers AI tools including Ask iManage, which it describes as built into iManage Cloud, so firms that stay on-premises should confirm which AI features they can use.

Before turning on any AI feature, ask where prompts and outputs are stored, whether client documents train any models, and which plan or add-on includes the tools. ABA Formal Opinion 512 explains the duties lawyers have when they use generative AI.

Winner: NetDocuments, narrowly, because every customer is on the cloud platform where its AI tools run.

Ease of use and rollout

Neither product is a weekend install. Both need planning for folder templates, security groups, and email filing habits, and both need training for attorneys and staff. iManage rollouts usually involve internal IT or a certified partner, and the system offers more depth than a small firm will use. NetDocuments still takes planning and training, but the cloud-only model removes infrastructure work from the project.

A sensible rollout for either product starts with one practice group, runs for a few weeks, and adjusts templates before the rest of the firm moves over. Assign a partner to champion the change, because the system only works if attorneys stop saving to desktops and personal inboxes.

Winner: NetDocuments for firms without a dedicated IT team.

Pricing and total cost

Neither vendor publishes prices. Both quote based on users, modules, and deployment, so you will need demos and written quotes to compare. When you request quotes, ask each vendor to include:

• License cost per user, with any minimum user count.
• Implementation, configuration, and data migration fees.
• Security and AI add-ons you are likely to want.
• Training and ongoing support levels.
• Contract length, renewal increases, and whether user counts can decrease.

For iManage on-premises, add your own server, storage, backup, and administration costs. For either cloud option, compare a three-year total rather than year one. Ask too whether pricing changes if you add offices, practice groups, or outside users later.

Winner: Unclear without quotes. NetDocuments avoids infrastructure costs by design, which usually helps smaller firms. Large firms with existing iManage investments may find staying put cheaper than switching.

How to run a fair evaluation

Because neither vendor offers a self-serve trial, the comparison happens in demos and pilots. Keep the process tight so both products face the same test. Send each vendor the same scenario list in advance and ask them to show it live with your sample data, not a scripted demo.

1. File a long email thread with attachments to a matter from Outlook, on desktop and phone.
2. Open a contract in Word from the DMS, edit it, and save a new version with comments.
3. Set up an ethical wall for one matter and show the audit log when a blocked user tries to open it.
4. Search for a clause across a practice group and check that walled matters stay hidden.
5. Export a full matter, including email, in a format you could load elsewhere.

Ask both vendors for references at firms of similar size and practice mix, and call them. Ask the references how long migration took, how attorneys adapted to email filing, and what they would do differently.

Which should you choose?

Choose NetDocuments if you want a cloud-only legal DMS with strong encryption and data residency controls, and you would rather not manage infrastructure. It fits small, midsize, and large firms that are cloud-first. Choose iManage Work if you are a midsize or large firm that wants deep matter workspaces, centralized security policies, and the option to run on your own servers, and you have IT staff or a partner to manage the rollout.

If your firm is still running on shared drives and email folders, either system will be a big step up. Spend as much effort on cleaning up your matter structure and filing habits as on picking the vendor, because both products depend on attorneys filing consistently.
