Zscaler this week delivered its latest cloud-based email security application designed to scan and secure messages sent from any device before it enters or leaves a customer's email system.

As an ancillary benefit, the new Software-as-a-Service (SaaS) suite also simplifies IT management and administration because it forces the CIO and his or her staff to adopt security procedures that deal with Web and messaging threats on an equal basis regardless of whether or not they're sent from a smartphone, laptop or desktop PC from within or outside the corporate firewall.

"Web and messaging security are no longer mutually exclusive," said IDC's Christian Christiansen. "Malicious URLs appear in emails, phishing attacks, and sophisticated blended threats that target multiple protocols."

Zscaler said the new offering incorporates real-time filtering to block spam and phishing attacks, as well as antivirus and antispam features that scrutinize all emails destined for the network email server.

It also includes data loss prevention (DLP) components for SMTP and Web-based email, and flexible policies that can be established by individual companies to define email flow and encryption policies.

"The new version of Zscaler gives new meaning to, and defines a new standard for, integrated Web and email security services," Zscaler CEO Jay Chaudhry said in a statement. "It also provides us unrivaled visibility into evolving threats across mail and Web globally."

The security application offers a single policy manager setting for email and Web security and inspects email and Web traffic from the cloud in real-time to detect potential malware campaigns, whether the email was sent from inside the firewall, from a remote worker using a Wi-Fi connection or from an anonymous smartphone halfway around the world.

It also features integrated reporting down to the transaction level so IT managers can get reports detailing exactly when, where and how email destined for the network was created.

Zscaler said the service costs between $1 and $5 per user each month depending on the size of the customer and number of services selected.
