Overview
iManage is the dominant document management system in large law firms and corporate legal departments worldwide. It organizes documents, emails, and related matter files into a unified, matter-centric workspace with deep integration into Microsoft 365 — the standard legal technology stack for most enterprise firms. The platform flagship product, iManage Work 10, delivers a modern browser-based interface that replaces the older DeskSite and FileSite clients without requiring Citrix for most deployments. Work 10 pairs with iManage Mail for one-click Outlook email filing, iManage Share for secure client-facing deal rooms and collaboration portals, and Security Policy Manager for enterprise ethical walls and need-to-know access controls. iManage is available in cloud, on-premise, and hybrid configurations. On-premise remains the choice for AmLaw 200 firms with strict data residency requirements or air-gapped security policies; cloud deployments are growing for new and mid-size firm implementations. The AI Search module uses legal language models and matter relationship graphs to surface relevant precedents and clauses faster than keyword queries alone. Pricing is enterprise and quote-based, scaling with firm size, deployment model, and which iManage modules are included. Most implementations require an iManage-certified reseller or partner for deployment and training. The platform is not cost-effective for firms under approximately 20 attorneys.
Key features
iManage Work 10
iManage Work 10 is the flagship DMS with matter-centric organization, full-text search, version control, and check-in/check-out across the firm document repository. The modern Work 10 interface runs in a browser and native desktop application — no Citrix required for most deployments. It replaces the older DeskSite and FileSite clients while maintaining compatibility with existing matter databases and folder structures. Work 10 supports bulk profiling, saved searches, and keyboard shortcuts designed for high-volume document environments.
iManage Mail
iManage Mail is the Outlook integration that files emails to the correct matter with one click, supports email threading, and handles attachments automatically. It eliminates manual drag-and-drop filing and the risk of emails sitting in personal inboxes instead of the firm DMS. Filing rules auto-suggest the correct client-matter profile based on email senders, recipients, and subject lines. iManage Mail handles high-volume email environments typical of BigLaw litigation and transactional practices without performance degradation.
iManage Share
iManage Share is a secure client-facing collaboration portal for sharing deal rooms, due diligence binders, and sensitive client deliverables. It replaces insecure email attachments for high-stakes document exchange — external parties access shared documents through a controlled, permissioned workspace. Activity tracking shows exactly which documents external parties opened and when, creating an audit trail for negotiations and closings. Share integrates with the iManage workspace so attorneys do not manage two separate document repositories.
AI-Powered Search
iManage AI Search understands legal language, matter context, and relationship graphs to surface the right precedent, clause, or email faster than keyword search alone. The model learns from usage patterns within the firm to improve recall for frequently retrieved document types — previous motion templates, deal memos, and similar matter structures. AI Search also powers similar document and related matter suggestions that appear when attorneys open a new file. This reduces time spent reconstructing research that already exists somewhere in the DMS.
Security Policy Manager
Security Policy Manager provides enterprise-grade ethical walls, need-to-know access controls, and compliance tracking — required for firms with conflicts screening and regulated client work. Ethical walls restrict document access at the matter level, preventing attorneys on opposing sides of a conflict from seeing each other files even within the same firm workspace. Policy violations trigger alerts rather than silently failing, giving conflicts counsel visibility into access events. This level of access control is a requirement for most AmLaw 200 conflicts policies and many corporate legal department security audits.
Deployment Flexibility
iManage supports cloud, on-premise, and hybrid deployment — an important differentiator from cloud-only document management systems. On-premise remains the choice for firms with data residency requirements, air-gapped security policies, or government contract obligations that prohibit cloud storage. The hybrid model allows firms to run some practice groups on cloud while maintaining on-premise for sensitive client categories. Cloud deployments on iManage Cloud receive automatic updates and managed infrastructure, reducing the IT overhead of the traditional on-premise model.

Frequently asked questions
iManage pricing starts around $50/user/month for smaller deployments, but enterprise pricing is quote-based. Contact iManage or an authorized reseller for a firm-specific quote that accounts for user count, deployment model, and which modules are required.
iManage Work 10 is the current version of iManage document management platform, featuring a modern browser-based interface, AI search, and full integration with Microsoft 365 — replacing the older DeskSite/FileSite clients.
iManage is preferred by large firms (AmLaw 200) for its on-premise deployment option, enterprise security depth, and email management capabilities. NetDocuments is cloud-native and better integrated with small-to-midsize legal tools. Both are enterprise-grade DMS; the right choice depends on firm size, deployment requirements, and ecosystem.
iManage offers cloud (iManage Cloud), on-premise, and hybrid deployment. Most new deployments are cloud or hybrid; on-premise remains available for firms with strict data residency requirements.
Yes. iManage has deep integrations with Outlook (iManage Mail), Word, Teams, and SharePoint — making it the standard DMS for Microsoft-centric law firm environments.
iManage does not offer a self-serve free trial. Enterprise DMS implementations are scoped and deployed through iManage-certified resellers or authorized implementation partners. Prospective clients can request a demo through the iManage website or their regional reseller to evaluate the platform before committing.
