Where each one falls short

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

Mimecast

  • No pricing is published for any product or plan, and every route ends at a quote or demo request
  • The platform is split into separately sold products for email security, awareness training, data protection and governance
  • Collaboration threat protection, DMARC analysis, incident response and email archiving are all further add ons on top of those

NetDocuments

  • Quote-only pricing per user with no published rates
  • Migrating an existing document store is a substantial project, and legacy metadata rarely survives cleanly
  • Aimed at mid-size and large firms; solo practices find it heavier than needed
  • Adoption depends on fee earners filing correctly, and habits are the hard part
