The Cisco Difference

Exclusive preventive and reactive technologies - including spam protection, data loss prevention (DLP), virus defense, email authentication, and tracking and reporting tools - work together to support a powerful security service.

Cisco Cloud Email Security offers customers the ability to outsource their spam problem to a vendor that provides better efficacy and higher accuracy while allowing more control and visibility into their cloud solution.


Today’s email security threats consist of viruses, spam, false positives, distributed denial of service (DDoS) attacks, spyware, and phishing (fraud). Cisco email security technology blocks all types of threats so that companies receive only legitimate messages. Cisco uses multiple methods to provide the utmost in comprehensive email security, incorporating preventive and reactive measures to strengthen your defense.

Proven Spam Protection

Cisco email security technology blocks undesirable email messages using a multilayered scanning architecture. Cisco Cloud Email Security delivers the industry’s highest spam catch rate, greater than 99 percent, with a less than one in one million false-positive rate.

Cisco reputation filters provide an outer layer of defense using data from the Cisco SenderBase® network to perform a real-time email traffic threat assessment and identify suspicious email senders.

Cisco Anti-Spam uses the industry’s most innovative approach to threat detection, based on the Cisco Context Adaptive Scanning Engine (CASE). This engine examines the complete context of a message, including what content the message contains, how the message is constructed, who is sending the message, and where the call to action of the message takes you. By combining these elements, Cisco Anti-Spam stops the broadest range of threats with industry-leading accuracy.

Powerful Virus Defense

By offering a high-performance virus scanning solution integrated at the gateway, Cisco Cloud Email Security provides a multilayered, multivendor approach to virus filtering.

Cisco Virus Outbreak Filters are a critical first layer of preventive defense against new outbreaks, detecting and stopping viruses hours before traditional virus signatures are available.

Advanced Controls

Cisco email security technology innovation delivers the highest levels of security and control. A range of email authentication solutions are supported by the Cisco security gateway, including Cisco Bounce Verification technology and a sophisticated feature set for signing outbound email with the Sender Policy Framework. These solutions help the intelligent mail system make more accurate decisions.

Sender Policy Framework (SPF) verification and signing means that messages are digitally processed to establish and protect identities with email senders and receivers on the Internet.

Cisco Bounce Verification tags messages with a digital watermark to filter bounce attacks at the network edge.

Directory Harvest Attack Prevention (DHAP) tracks spammers who send to invalid recipients and blocks attempts to steal email directory information.

Advanced Malware Protection features file reputation scoring and blocking, file sandboxing, and file retrospection for the continuous analysis of threats, even after they have traversed the email gateway.

Sophisticated Outbound Filtering Protects Sensitive Information

Outbound filtering is just as important as inbound security. By applying additional message safeguards and policies, outbound filtering helps protect and secure sensitive information.

Content filtering can be used to add headers or footers to email, or to keep email with confidential or inappropriate information from entering or leaving your network.

Transport Layer Security (TLS) uses digital certificates to authenticate the user as well as the network.

Comprehensive Administration and Easy Access for Co-Management

A comprehensive support portal helps ensure that customers always have access to an extensive knowledge base of subject matter expertise to assist with their needs. Using the Cisco Security Portal, customers can create a customized homepage to quickly access their unique security interests. They can view all current and historical events and tickets, geographical data, security graphics, trends, and network status and performance.

Consolidated and robust reporting options analyze traffic data from geographically diverse infrastructure deployments to provide fully integrated reports. Cisco’s third-generation reporting technology enables unprecedented insight into even the highest-volume networks in the world. Detailed and accurate information is coalesced into clear and informative reports, suitable for all levels of an organization.

Message tracking gives customers real-time visibility into messages. This feature can help resolve help-desk calls quickly by determining the exact location of a message. Instead of having to search through log files, the administrator can use the flexible tracking interface to locate messages.
