Lower costs

By stopping spam and viruses before they reach your network, you can extend the life of your existing infrastructure. This means lowering the costs associated with your network, your mail server, and your current email security product.

Reduce maintenance burden

Hosted Email Security is continuously updated 24x7 by Trend Micro's worldwide team of security experts. It's a "no maintenance required" solution that—according to customer surveys—can cut the number of hours you spend on email security maintenance by as much as 50%.

Accelerate productivity

Reducing infrastructure costs and maintenance requirements leaves you more time to implement critical projects like voice over IP, adding mail server capacity, or securing your increasingly mobile workforce. And Hosted Email Security also includes an industry-leading service level agreement that commits us to 100% uptime.

Automatically encrypt email

Don't rely on end users to secure vital data. With policy-based encryption from Trend Micro, you can automatically enforce compliance requirements and protect confidential information. Trend Micro Hosted Email Encryption is an optional add-on that identifies particular types of content and encrypts emails when rules are triggered. To apply it, simply check the appropriate box.

Email is mission critical. Email security should be mission critical too.

Trend Micro Hosted Email Security is a no-maintenance-required solution that delivers continuously updated protection to stop spam and viruses before they reach your network. Here's how:

  • We add value to your current environment
  • We provide always-up-to-the-minute security
  • We have the infrastructure you need

Cloud-based security is only as good as the infrastructure behind it

We stand by the availability of our robust, fully redundant, geographically distributed data centers. If one data center becomes unavailable, emails are automatically and transparently re-routed to a different data center, with no impact on delivery. That's why—unlike other vendors—we measure downtime in minutes, not hours.
