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.

What is SecureTide?

SecureTide is a fully managed email protection service that prevents up to 99% of spam, phishing attempts, viruses, and other internet pollution from ever reaching your network. Since SecureTide is delivered as a service there is nothing to install, configure or manage. Setup is easy and usually takes less than an hour, regardless of the size of the organization.


How does SecureTide determine which email to block?

AppRiver's service relies on a collaboration of automated systems and people to block spam and viruses. The system is designed as a continuous, large-scale learning process where human and machine elements work together to evaluate messages. The machines do things that the people can't, such as comparing and cataloging features on millions of messages very quickly. Likewise, people do things that the machine can't, like recognizing a new spam or obfuscation technique with a single spam sample. (For example, humans can quickly recognize sexual innuendo.)


How effective is SecureTide?

In its evaluation of AppRiver's technology for its 2006 "Pattern Recognition: Technical Insights" report, research firm Frost & Sullivan observed, "AppRiver's real skill set comes from speed-spam and virus capture rates second to none in the security industry." More importantly, SecureTide has maintained a 97% customer retention rate since 2002.


Does SecureTide work quickly?

In a fraction of a second, every piece of your company's email is subjected to a blend of proven filtering techniques. SecureTide filtering systems are constantly updated so illicit email is quickly identified and blocked. SecureTide has approximately 200-250k active signature tests at any given time. Currently, SecureTide processes over 2.5 billion messages per month for about 53,000 companies on six continents.


How often are SecureTide's rules updated?

The service is maintained and updated an average of 4,000 to 8,000 times a day, every day.


Does SecureTide screen outgoing mail as well?

Yes. Our outbound email filtering program cleans all internal emails before they are sent from the network's system. This spam filtering service reduces the risk of improper routing and misuse of the company's resources, as well as unapproved messaging.


What scanning engines do you use?

AppRiver employs a variety of spam-blocking techniques, but the heart of our system is MessageSniffer, our proprietary technology that uses advanced pattern recognition and a regularly updated "rules" database to accurately identify spam. MessageSniffer searches for combinations of spam features including message sources, common obfuscation techniques, email and URL targets and fragments, and even coding styles.


Who owns the technology behind SecureTide?

AppRiver owns all core email filtering technology used in its SecureTide service, which allows the company to be highly adaptable in the fast-changing anti-spam environment. It also ensures the system's quality and cost variables remain under AppRiver's control.


How long does it take to set up?

AppRiver's internal standard is less than 24 hours, but account creation and MX record change notices usually are sent out in under two hours.


Why do I have to change my MX Record?

SecureTide resides between the Internet and your mail server. If your email is hosted by a third party, SecureTide sits between the Internet and your mail hosting company. By replacing your MX records with MX records provided by SecureTide, your inbound mail will travel from the internet, through our screening process, where it will be scanned for spam and viruses, and then be passed to your network.


What happens to the captured mail and spam junk?

Each user is sent a daily Held Spam Report. If SecureTide identifies a legitimate message as spam, users can instantly release the wanted message directly from the report. Web access to the quarantined email is also available to administrators and end-users.

What happens to bulk emails?

By configuring a simple content rule in the Customer Portal, you can use the power of SecureTide to allow these items to be categorized and then easily sorted around your inbox to a folder of your choosing.


Is my mail protected during a disaster?

Yes. If a client server is not accepting email for any reason, SecureTide's delivery manager will encrypt and queue email until the client server is back online. So even if your internal servers are damaged or destroyed, you will still have access to several days of email that has been preserved on AppRiver's servers.


What is the difference between Open and Closed domain modes?

Open mode is the default domain mode setting. It means that AppRiver will process all messages regardless of who they are addressed to. This setting is desirable for new accounts that have not yet entered all their email addresses. Setting your domain to Closed mode will only process mail for the addresses entered in the web interface. This will not bounce the messages and let spammers detect valid addresses. It will simply hold incoming messages for users not on your users list after they are received.


How do I start using SecureTide?

First, activate the Free 30 day trial form. This will prompt us to email you new MX records within a few hours, typically within the hour during the normal business day. The next step will be to change your MX records, which we can help you coordinate. Once the MX records have been changed, you are finished. No more spam.
