Mimecast

What It Does

Mimecast is a cloud email security and management company. It is not primarily a legal-tech vendor, but its archiving platform includes legal hold and e-discovery features relevant to in-house legal and compliance teams: preserving email and collaboration data for litigation, proving chain of custody, and searching the archive for retrieval and export. These sit alongside its main business of email threat protection, anti-phishing, and continuity.

What We Found

Mimecast was founded in 2003 and is headquartered in London. It serves a broad enterprise market across regulated industries; the legal hold and e-discovery use case is one application of its archiving product rather than a standalone legal product. The company was taken private by Permira in 2022.

What We Haven’t Verified

• The depth of the e-discovery feature set relative to dedicated e-discovery platforms — not tested.
