91% of mail received by companies in September was spam

Over 91% of email received by companies in September was spam, according to data collected by the TrustLayer Mail managed security service from Panda Security.

This percentage is slightly up on the figure for last month (87.49%), confirming the trend that has prevailed throughout the year with spam percentages around the 90% mark.

The most frequently detected malicious codes in corporate email were the Netsky.P worm and the Downloader.PSJ trojan.

This Panda Security service guarantees 100% virus-free mail backed by a Service Level Agreement, so email-borne threats are blocked before they even reach company mailboxes.

TrustLayer Mail includes technology that combines signature-based protection with a system for consulting a global network of continuously updated security servers. Thanks to this system, it is able to detect 98.5% of all spam. It also returns a false positive ratio of just 1 in every 27,905 messages processed. This data has been compiled from the networks protected by TrustLayer Mail during the solution’s trial phase.

The TrustLayer system architecture offers load-balancing and redundancy and is designed to offer maximum availability (99.99%) to ensure an uninterrupted message delivery service: 24 hours a day, 7 days a week. This high availability is supported by a team of experts, day and night, monitoring the 24×7 mail service and resolving any incidents.

The service is provided from one of the Managed Data Centers of Spain’s largest Telco (Telefonica), in the heart of the Internet, guaranteeing service availability at all times.

“It is essential to protect corporate networks against worms, spam and other threats. If a user runs a file containing malicious code, either through social engineering or simply by mistake, the entire network could be affected. That’s why it’s advisable to ensure that infected mail and spam are intercepted before they even reach the network using a managed service such as TrustLayer”, explains Luis Corrons, Director of PandaLabs.
