Trend Micro Hosted Email Security
Stop spam. Save time. Sleep easy.
Networks
Hosted Email Security is the new name for InterScan Messaging Hosted Security.
Overview:
Email is mission critical, but spam and email-based malware volume is growing exponentially; it’s difficult to keep up. At the same time, other critical projects are pending— like Voice over IP, adding infrastructure capacity and securing your mobile workforce—but that doesn’t mean you can afford to neglect email security maintenance. Doing so will lead to a decline in your email security and spam-blocking effectiveness, which will inevitably lead to email delivery latency, mail server downtime, and even a major network outage.
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.
With core technologies rated #1 for antispam and #1 for anti-malware, according to independent benchmarking, Trend Micro Hosted Email Security protects more than 30,000 companies in more than 110 countries worldwide, and includes an industry-leading money-back Service Level Agreement.

In independent benchmark tests, Trend Micro Hosted Email Security achieved the highest spam catch rate, beating eight popular antispam solutions.2 And we commit to block 99%+ of all spam, or you may be eligible for money back.
