Enhance your inbox with a smart filter designed for you.

SecureTide® already blocks 99 percent of spam and viruses, keeping your inbox clean and your network safe. With Quarantine Alerts, SecureTide now analyzes your email history and will automatically notify you if a message from or to a previous contact is quarantined for any reason – which gives you total peace of mind that your spam filter isn’t keeping secrets from your inbox. It’s time to raise expectations on what a spam filter should be able to do with SecureTide from AppRiver.


With SecureTide®, there is no onsite hardware or software required and set-up is easy: A simple change to your MX records is all it takes to get started. You’ll receive a daily Held Spam Report to see the spam you’re (not) missing. You can also find and restore any legitimate messages we might mistake for spam. To make SecureTide even more effective, the service also allows you to adjust your settings to add or block other senders automatically.

Here’s the best part: You can try SecureTide free for 30 days. Once you see how effectively SecureTide works, simply pay a low monthly, per-user fee to keep it. And there’s no long-term obligation or cancellation fee, so you can stop the service any time you’d like.

Information Security

Whether it’s financial data, user account information or confidential email, many states are requiring companies to keep electronic communications private.

Transport Layer Security

TLS, or transport layer security, provides a basic level of information security by encrypting the link between one mail server and another. Once a secure channel between two companies has been established, communications between them is protected with no further effort required.

TLS is an optional feature with AppRiver’s SecureTide® Spam & Virus Filtering that is available by purchasing AppRiver’s SmartHost service.

Going Beyond TLS

AppRiver provides TLS for clients who require encrypted server-to-server connections. For those who need user-to-user encryption, the company recommends CipherPost Pro® Email Encryption service.

CipherPost Pro is user-based and user friendly. Delivered through AppRiver’s trusted Software as a Service (SaaS) delivery platform, the CipherPost Pro encryption system enables end-to-end, content level encryption of email and mobile messages.
