AppRiver has one clear value proposition: to offer businesses of all sizes secure messaging solutions. As the company that introduced secure Hosted Exchange to the market in 2006, they needed a very fast, lightweight antivirus engine that would complement their SecureTide service. After a thorough evaluation process, they found ESET NOD32 Antivirus to be the most reliable and stable platform. It now protects more than 50,000 mailboxes for AppRiver.
