TREND MICRO ENDPOINT SECURITY HIGH PERFORMANCE FOR EVERYDAY USAGE SCENARIOS

NSS Labs, an independent third party testing lab, conducted a series of comparative tests to assess the
performance and the resource impact of leading endpoint security suites. These tests simulated everyday
user activities to assess the impact of security on user productivity. Trend Micro's results in these tests
speak for themselves. Our continuous efforts to lower endpoint resource consumption have been extremely
successful and the NSS test results showed that in the categories that truly impact everyday endpoint usage
and user productivity, Trend Micro OfficeScanTM 8.0 outperforms competitor’s solutions. To learn more

EVERYDAY USE CASE 1: SCANNING THE SYSTEM FOR MALWARE.
While all of today’s anti-malware solutions provide real-time on-access scanning, running full scans on
endpoints is still a best practice for many enterprises. Typically, these full scans need to be scheduled at
times where most of the endpoints are up and running, generally during business hours. Thus the resource
consumption and duration of this operation has a significant impact on a user’s ability to perform regular
duties. Trend Micro OfficeScan has a slightly higher impact on CPU utilization during full scans, but it
finishes scans in just a fraction of the time needed by competitor’s products.

During the full scan, Trend Micro OfficeScan requires significantly less memory than the other products in
the test. This means that users are able to continue to work and be productive while a scan is running. For
endpoints using McAfee, Symantec, or Sophos endpoint security, a full scan is virtually impossible, as the
software alone consumes about 1GB of memory during that scan operation.

EVERYDAY USE CASE 2: STARTING APPLICATIONS
In today’s enterprises, users are required to work with various applications, sequentially or simultaneously.
Users open and close applications, or have one application invoke key components from another application
(for instance, MicrosoftTM Outlook uses MicrosoftTM Word as the default editor for emails). If endpoint
security causes a delay in opening a program, it has a significant impact on the user’s capability to easily
switch from one working context to another, thus impacting overall productivity. Of all tested endpoint
security products, Trend Micro OfficeScan adds the least delay during application warm-start, contributing to
increased overall productivity and user experience.


EVERYDAY USE CASE 3: DOWNLOADING FILES
It is often necessary for users to access and quickly review data found on the Internet. The ability to do so
without the security solution adding significant delay is important. New Web 2.0 technologies and internal
portal applications can also delay web downloads, impacting a user’s ability to access and work with shared
files. In the average of several tests conducted with various file formats and file sizes, Trend Micro
OfficeScan adds the least overhead, thus contributing to easy access and uninterrupted flow of work.

SUMMARY
Out of four leading endpoint security solutions Trend Micro OfficeScan performs best in common everyday
operations. These operations were chosen from a variety of tests performed by NSS-labs to best illustrate
the real-life scenarios most likely to impact a user’s productivity. With the least impact on the most common
everyday business actions, Trend Micro OfficeScan enables enterprises to support productivity, increase
user efficiency, and save on the cost of administration.
