Email Security
What Is the Value of Cisco Cloud Email Security?
Cisco® Cloud Email Security provides cloud-based email protection,
helping organizations reduce their onsite data center footprint and
reduce costs. The solution is built on the same comprehensive platform
that protects the email infrastructure for 40 percent of the Fortune 1000
and eight of the 10 largest ISPs. Microsoft Office 365 customers can
also get the same industry-leading protection with Cloud Email Security
for Office 365.
How Is the Cisco Cloud Offering Unique?
Cisco Cloud Email Security delivers several differentiating cloud features:
• Dedicated cloud infrastructure: Each cloud customer has a
dedicated email security instance, which is hosted in multiple Cisco
data centers.
• Cloud capacity assurance: Users are protected, and peak
performance is maintained, regardless of whether spam volumes
increase. Additional capacity is always included with a simple per-
user, per-year pricing model.
• Cloud availability guarantee: Cisco Cloud Email Security guarantees
99.999 percent uptime, so security is always available and working
for you through multiple data centers. Cisco has multiple cloud data
centers worldwide.
What Problems Does Cisco Cloud Email Security
Help Solve?
Cloud Email Security monitors and filters all inbound and outbound email
traffic using effective policy-based data loss prevention and encryption.
Its sophisticated filter strategy blocks targeted attacks using reputation,
malware, and outbreak filters.
Cisco Talos
Cloud Email Security uses the power of Cisco Security Talos, the
largest threat detection network in the world, to provide proven, zero-
day threat protection to all users wherever they are. It monitors and
detects threats from:
• More than 75 TB of web data per day
• More than 1.6 million deployed devices
• More than 150 million endpoints
• More than 13 billion web requests per day
• More than 35 percent of the world’s email traffic

Why Is Email Security So Challenging for Today’s
Enterprises?
Targeted attacks use social engineering that can trick even the most
discriminating user into opening an email and clicking a malicious link.
Email is a platform for known and emerging threats such as:
• Blended attacks that use web links to phishing sites
• Advanced malware that is difficult to detect
• Highly targeted attacks using social engineering
• Insider threats and outbound attacks that put intellectual property and
customer assets at risk
The Email User Evolution
Another challenge to email security is that today’s users are not
checking text-based messages from a workstation behind the company
firewall. Instead, they are accessing rich HTML email through multiple
devices—anytime, anywhere—and not always through company-
supported devices. According to Cisco’s Connected World Technology
Report, three in every four employees around the world have multiple
devices, and many of these workers use more than one device for work.
The adoption of cloud-based hosted email solutions increases the need
for advanced protections not provided by consumer-oriented, one-
size-fits-all security. These hosted mailboxes need the security features
provided by Cisco solutions.
What Are the Deployment Options for Cisco Cloud
Email Security?
Cisco Cloud Email Security: This is a cloud-based software-as-a
service (SaaS) offering that requires no onsite hardware because it
resides in highly secure Cisco data centers. For organizations that
require sensitive data to remain on premises and are especially
concerned about the risk of performance degradation, Cisco offers
additional solutions.
Cisco Hybrid Email Security: This service bundles features for the on-
premises and cloud deployments of email security. It divides control
between your organization’s site and Cisco’s cloud-based SaaS
offering. Like Cisco Cloud Email Security, the hybrid service provides
dedicated email security instances in Cisco data centers, but you retain
access to, and visibility into, both on-premises and cloud infrastructures.
On-premises appliances add the ability to deliver advanced outbound
control with encryption, data loss prevention, and onsite Lightweight
Directory Access Protocol (LDAP) integration. In addition, if you are
transitioning from on-premises to the cloud, you can do so in phases.
You can change the number of on-premises versus cloud users at any
time throughout the term of their contract, assuming the total number
of users does not change. This provides deployment flexibility as your
organization’s needs change.

Cisco Managed Email Security: This customized email service
stops spam and viruses to help secure the email infrastructure while
reducing the burden on IT. It uses a combination of high-performance
appliances and expert monitoring and management to comprehensively
protect complex email infrastructures. Designed to flexibly manage
a growing email infrastructure, Cisco Managed Email Security features
a structured implementation model with well-defined phases:
evaluation, system design, system implementation, service activation,
and product implementation.

The Cisco Cloud Email Security Advantage
Cloud Email Security includes threat-protection capabilities to help
eliminate a diverse range of known and emerging threats. It features
high-performance virus scanning, outbreak filters, advanced antispam
techniques, and innovative context-sensitive detection technology,
encryption, and data loss prevention. Advantages include a data loss
prevention architecture and end-to-end encryption.
Data Loss Prevention Architecture with RSA
Email is the leading vector for data loss. To help companies address
this risk more effectively, Cisco began integrating data loss prevention
technology into its email security solutions in 2009. Through this
integration, Cisco provides customers with comprehensive global
regulatory compliance coverage; best-in-class accuracy for identifying
sensitive, data-comprehensive remediation options; and ease of
deployment and management.
End-to-End Email Encryption
Cloud Email Security features the Cisco Registered Envelope Service,
a flexible and scalable cloud-based solution that helps organizations
support their security requirements—including meeting regulatory
compliance demands and protecting intellectual property— without
having to invest in additional hardware. It also eliminates the complexity
of encryption and key management, so users can send and receive
highly secure messages as easily as unencrypted emails.
