AppRiver

What AppRiver does

AppRiver is a US-based cloud cybersecurity provider founded in 2002 in Gulf Breeze, Florida, originally focused on SaaS-based anti-spam, hosted Microsoft Exchange, email encryption, and web protection. Its platform delivers email security (encryption, threat protection, continuity, message privacy), endpoint protection (EDR, MDR, DNS protection), data backup and recovery (server and endpoint), continuity and compliance (archiving, availability, recovery, migration), and SaaS backup for Microsoft 365, Google Workspace, Salesforce, Box, and Dropbox.

The company built its distribution around an MSP Partner Program and a direct customer portal, with deep integration into the Microsoft Azure and Microsoft 365 ecosystems. AppRiver operates on a subscription-based recurring revenue model with annual billing, with all software updates and upgrades included in the subscription. Its primary customer segments are small and medium businesses and managed service providers, with a secondary enterprise segment.

In 2019, AppRiver was acquired by Zix Corporation, which brought proprietary email encryption technology (ZixGateway, ZixMail) and compliance archiving (Mailstore) into the portfolio. Zix was subsequently acquired by OpenText Corporation in 2021, and AppRiver now operates as a legacy brand within the publicly traded OpenText Cybersecurity division (NASDAQ: OTEX), no longer functioning as an independent entity.
