NetDocuments is a cloud-based document and email management service that provides enterprise-level security, mobility, disaster recovery, and collaboration solutions for organizations with high data security requirements, such as law firms, financial institutions, and insurance industries. Data security and strict digital asset protection are key differentiators of the service that allow organizations to confidently store and collaborate on their documents and email. Additionally, the powerful integrations with Microsoft Office allow for smart editing, drafting, searching, and version control. Extranets, secure links, and client portals provide collaboration and security to outside parties who require real-time access to relevant documents.
NetDocuments was one of the world's first true software as a service (SaaS) enterprise applications (launched in 1999) and all of its functionality can be accessed through a web browser on any device including the iPad, iPhone and Android-based devices.
