Innovative Security Platform Delivers Industry-Leading
Performance and Accuracy
Cisco IronPort web security appliances help enterprises
secure and control web traffic by offering multiple layers of
malware defense on a single, integrated appliance. These
layers of defense include Cisco IronPort Web Reputation
Filters, multiple anti-malware scanning engines and the Layer
4 (L4) Traffic Monitor, which detects non-Port 80 malware
activity. The Cisco IronPort S-Series is also capable of
intelligent HTTPS decryption, so that all associated security
and access policies can be applied to encrypted traffic.
A fast web proxy is the foundation for security and acceptable
use policy (AUP) enforcement. It allows for deep content
analysis, which is critical to accurately detect devious and
rapidly mutating web-based malware. Powered by the
proprietary Cisco IronPort AsyncOS operating system, the
web proxy includes an enterprise-grade cache file system.
This system efficiently returns cached web content through
intelligent memory, disk and kernel management – easily
ensuring high performance and throughput for even the
largest of networks.
Industry-Leading Acceptable Use Policy Enforcement
Cisco IronPort Web Usage Controls, available on all Cisco IronPort S-Series web security appliances, provide industryleading
visibility and protection from web use violations
through a combination of list-based URL filtering and
real-time dynamic categorization. This unique solution is
powered by Cisco Security Intelligence Operations (SIO),
which uses global Internet traffic visibility and analysis to
target categorization efforts and provide timely updates,
maximizing URL list-based efficacy.
Cisco IronPort URL Filters offer the broadest reach and the
highest accuracy rate in controlling web content. Cisco’s
database contains over 20 million sites (corresponding
to over 3 billion pages), with global coverage across 70
languages and 200 countries.
Cisco IronPort URL Filters provide industry-leading coverage
and accuracy against web traffic requests. An administrator
can easily configure access policies based on 52 pre-defined
categories and an unlimited number of custom categories.
Time-based policies are also supported for truly flexible
acceptable use policy management.
AUP , application and protocol control are facilitated at
a granular level, regardless of the protocol or application
flowing through the network perimeter. The Layer 4 Traffic
Monitor looks for “phone-home” malware activity, while
intelligent HTTPS decryption inspects encrypted data for
security or AUP violations. The Cisco IronPort S-Series brings all of these
capabilities together to provide a single touch point for
administrators who want to control the data entering and
leaving their networks.
Multi-Layer, Multi-Vendor Malware Defense-in-Depth
An integrated Layer 4 (L4) Traffic Monitor scans all
ports at wire speed, detecting and blocking spyware
“phone-home” activity. By tracking all 65,535 network ports,
the L4 Traffic Monitor effectively stops malware that
attempts to bypass Port 80. In addition, the L4 Traffic
Monitor is able to dynamically add IP addresses of known
malware domains to its list of ports and IP addresses to
detect and block. Using this dynamic discovery capability,
the L4 Traffic Monitor can monitor the movement of malware
in real time – even as the malware host tries to avoid
detection by migrating from one IP address to another.

The Cisco IronPort S-Series combines revolutionary technologies to provide multi-layered web security on a single appliance.
Cisco Security Intelligence Operations (SIO) is an
advanced security infrastructure that provides threat
detection, correlation and mitigation to continuously provide
the highest level of security for Cisco customers. Using a
combination of threat telemetry, a team of global research
engineers and sophisticated security modeling, Cisco SIO
enables fast and accurate protection, allowing customers to
securely collaborate and embrace new technologies.
Cisco Security Intelligence Operations is a sophisticated
security ecosystem consisting of three components:
- Cisco SensorBase: The world’s largest threat monitoring
network that captures global threat telemetry data from a
massive footprint of Cisco devices.
- Threat Operations Center: A global team of security analysts
and automated systems extract actionable intelligence.
- Dynamic Updates: Real-time updates automatically
delivered to security devices, along with best practice
recommendations and other content, help customers track
threats, analyze intelligence and ultimately improve their
organization’s overall security posture.
The industry’s first and best web reputation filters provide
a powerful outer layer of malware defense. Leveraging Cisco
Security Intelligence Operations (SIO), Cisco IronPort Web
Reputation Filters analyze over 50 different web traffic- and
network-related parameters to accurately evaluate a URL or IP
addresses’ trustworthiness. Cisco IronPort Web Reputation
Filters examine every request made by the browser (from
the initial HTML request to all subsequent data requests) –
including live data, which may be fed from different domains.
This gives these filters a unique advantage over vendors that
reduce web reputation to a simple URL filtering category.
Cisco IronPort Web Reputation Filters are the industry’s
only reputation system to include botsite protection, URL
outbreak detection and exploit filtering – protecting users
from exploits delivered through cross-site scripting (XSS),
cross-site request forgery, SQL injections or invisible iFrames.
The power behind this revolutionary reputation technology
comes from the system’s pattern-base assessment
techniques and per-object scanning capabilities.
The Cisco IronPort Anti-Malware System gives the Cisco
IronPort S-Series the distinction of being the first solution on
the market to offer multiple anti-malware scanning engines on
a single, integrated appliance. Moreover, an administrator
can run these scanning engines simultaneously to enable
greater protection against malware threats, with little-to-no
performance degradation. This system leverages the Cisco
IronPort Dynamic Vectoring and Streaming (DVS) engine, and
verdict engines from Webroot and McAfee, to provide bestof-
breed protection against the widest variety of web-based
threats. These threats can range from adware, browser
hijackers, phishing and pharming attacks to more malicious
threats such as rootkits, Trojans, worms, system monitors
and keyloggers.
Scanning engines from Webroot and McAfee are fully
integrated into the Cisco IronPort web security appliances.
The Webroot scanning engine, backed by a threat research
team at Webroot, performs both request- and response-side
scans. Efficacy and coverage are strengthened by Phileas
(the first automated spyware detection system), which
identifies existing and new threats by intelligently scanning
millions of sites daily. The McAfee scanning engine is backed
by Avert Labs, the world’s top threat research center. The
McAfee database includes both virus and malware signatures
and can be configured to perform both signature-based and
heuristics-based scanning.


Native FTP protection enables complete visibility into FTP usage – enforcing acceptable use and data security policies, and preventing malware infections.
The Cisco IronPort DVS engine was built to provide
an integrated, single-appliance solution with multiple
anti- malware scanning engines from different vendors.
It employs sophisticated object parsing and streaming
techniques to enforce acceptable use policies and security
features for web traffic. It simultaneously leverages
hardware optimizations (such as multi-core scanning) to
distribute these parallel operations and fully utilize the
system’s resources. The result is a ten-fold improvement
in performance when compared to first-generation
scanning solutions.
HTTPS decryption enables the Cisco IronPort S-Series to
enforce acceptable use and security policies over HTTPSdecrypted
data. This is the first solution to use web reputation
and URL filtering to make HTTPS decryption decisions.
For example, a banking site can be bypassed for HTTPS
decryption – unless its web reputation score is low, in which
case the HTTPS connection is decrypted to scan content for
malware, or blocked outright. With this ability, administrators
no longer have to sacrifice security for privacy.
Powerful Data Security Enforcement
Data security and data loss prevention empower organizations
to take quick, easy steps to enforce common sense data
security policies. For example, preventing engineers from
sending design files by webmail, blocking uploads by finance
staff of Excel spreadsheets over 100KB, or preventing posts of
content to blogs or social networking sites. These simple data
security policies can be created for outbound traffic on HTTP,
HTTPS and FTP.
For enterprises that have already invested in special-purpose
data loss prevention (DLP) systems, the Cisco IronPort
S-Series offers an option to interoperate with DLP vendors via
ICAP. By directing all outbound HTTP, HTTPS and FTP traffic
to the third-party DLP appliance, organizations can allow or
block based on the third-party rules and policies. This also
enables deep content inspection for regulatory compliance
and intellectual property (IP) protection, incident severity
definition, case management and performance optimization.
Native FTP protection allows Cisco IronPort web security
appliances to provide complete visibility into FTP usage,
enforcing acceptable use and data security policies, and
preventing malware infections. Acting as an FTP proxy, the
Cisco IronPort S-Series enables organizations to exercise
granular control, including: allow/block FTP connections,
restrict users/groups, control uploads/downloads, and
restrict sent/received files to certain types or sizes.
Additionally, Cisco IronPort web security appliances can
score FTP servers with Web Reputation Filters (Cisco’s
industry-leading reputation service) and scan downloaded
content for malware and spyware payloads with the IronPort
Dynamic Vectoring and Streaming (DVS) engine. Cisco’s FTP
protection enforces simple, common sense data security
policies based on file metadata, user, URL category and
reputation. Alternately, FTP traffic can be passed to an
external DLP solution for additional, more granular, scanning.
The Cisco IronPort S-Series now has comprehensive
coverage for the three most common protocols carrying
business information across the boundary and over the
Internet – HTTP, HTTPS and FTP.
Comprehensive Management and
Reporting Capabilities
Cisco IronPort Web Security Manager provides a single,
easy-to-understand view of all access and security policies
configured on the appliance. Administrators manage all
web access policies (including URL filtering, time-based
policies, reputation filtering and malware filtering) from
a single location. Additionally, administrators can mix
and match client-based criteria (e.g. client IP address,
authenticated username, etc.) and destination-based criteria
(e.g. URL, URL category, proxy port, etc.) to flexibly determine
when each set of policies is applied.
Cisco IronPort Web Security Monitor offers valuable
insight into overall web activity, as well as threat identification
and prevention, within corporate networks. These on-box
and off-box reports are designed to provide actionable
information as well as historical trends. Enhanced
reporting provides enterprises visibility into policy and
security violations.
Multiple deployment modes enable flexibility within a
corporate network. Modes include deployment as an explicit
forward proxy for the network or transparent deployment
off an L4 switch or a WCCP router within the network. Each
Cisco IronPort web security appliance can be configured as
a standalone proxy or to co-exist with other proxies (such as
in a proxy hierarchy for conditional routing, failover and load
balancing).
Enterprise-grade SNMP facilitates hands-off monitoring
and alerting for key system metrics including hardware,
performance and availability. Support for SNMPv1, 2, and 3,
along with a comprehensive enterprise-class alert engine,
ensure oversight for all system parameters – including
hardware, security, performance and availability.
Integrated authentication via standard directories (such
as LDAP or ActiveDirectory) and the ability to implement
multiple authentication schemes (such as NTLM or Basic)
lets enterprises deploy the Cisco IronPort S-Series
seamlessly, while taking advantage of pre-existing
authentication and access control policies within their
networks. Features such as multi-realm authentication
(which enables authentication against multiple authentication
domains) provide flexible failover scenarios and multiorganization
deployments.
Cisco IronPort web security appliances also enable warn/
continue pages to allow the organization to educate users on
corporate acceptable use and security policies, restricted
guest access for visitors, and re-authentication for on-the-fly
privilege override. Given the diversity of ways in which group
information is stored in user directories, the Cisco IronPort
S-Series supports obtaining group information from a group
object, as well as from an attribute in the user’s profile.
These features offer increased flexibility and richness
in policy and authentication to meet the requirements of
sophisticated enterprises.

The Cisco IronPort S-Series’
sophisticated reporting tools yield
a complete real-time and historical
view of web traffic, as well as threat
activity and prevention – providing
unprecedented security insight
Extensive logging allows enterprises to keep track of all
web traffic, benign and malware-related. Standard log formats
include Apache, Squid-detailed – along with the ability to
specify custom log formats, consistent with enterprise
logging policies. Administrators can enable, disable and set
log subscriptions, or set log rollover and size limits, based on
log types.
In addition to the Apache and Squid log file formats, the Cisco IronPort S-Series supports the W3C-standard Extended
Log File Format (ELFF). This allows administrators to use
many third-party log analyzer tools, and also enables the
generation of customized logs for various audiences. For
example, separate logs for IT, HR, and top management –
each with a customized set of logging fields.
Benefits:
Single Appliance Security and Control The Cisco IronPort
S-Series offers a single appliance solution to secure and
control the three greatest web traffic risks facing enterprise
networks: security risks, resource risks and compliance risks.
Mitigate Malware Risks and Costs With malware infecting
approximately 75 percent of corporate desktops, there is
considerable overhead around managing infected desktops,
ensuring minimal downtime to the end-user and minimizing
the risk of information leakage.
By stopping these threats at the network perimeter with
Cisco IronPort web security appliances, enterprises can
significantly reduce the administrative costs, prevent attacker
“phone-home” activity on networks, reduce support calls,
enhance worker productivity and also eliminate the business
exposure that accompanies these threats.
Complete, Accurate Protection Cisco IronPort S-Series
appliances are designed from the ground up to address the
broadest range of web-based malware threats, including
those from the use of FTP and dynamic Web 2.0 sites.
A multi-layered defense that includes Cisco Security
Intelligence Operations, Cisco IronPort Web Usage Controls,
Cisco IronPort Web Reputation Filters and Cisco IronPort DVS
technology (with multiple anti-malware scanning engines
running simultaneously), ensures industry-leading accuracy.
This multi-layered protection is based on a deep content
application-layer inspection, as well as network-layer pattern
detection, checking both inbound and outbound activities.
These innovations make the Cisco IronPort S-Series the
industry’s most secure web gateway.
Enforce Acceptable Use Policies (AUP ) By implementing
acceptable use web policies, enterprises can not only
conserve resources for work-related web usage, but also
inform end-users to help shape web access behavior over
time. Enterprises can increase the amount of time that
employees spend on business-oriented activities, reducing
misuse of enterprise networks and bandwidth.
Web Application Control

Simplified Data Security The data loss problem extends well
beyond malware. Employees can easily use webmail to send
a message including proprietary information, post confidential
data on social networks and blogs, or transfer financial
documents over FTP to a server outside the corporate network.
Making sure that sensitive data does not leave the corporate
boundary – while allowing users to leverage the full power of
the Internet – is an important and challenging issue to solve.
Cisco IronPort web security appliances enable organizations
to take quick, easy steps to enforce common sense data
security policies for outbound traffic on HTTP, HTTPS and FTP.
Reporting Visibility The Cisco IronPort S-Series appliances
deliver real-time and historical security information, allowing
administrators to quickly understand web traffic activity.
Real-time reports let administrators identify and track issues
such as policy violations and security violations as they occur.
Historical reports allow administrators to identify trends and
report on efficacy and ROI.
Enterprise-Scale Performance Cisco IronPort web security
appliances scale to meet the unique scanning needs of web
traffic, thereby ensuring that the end-user experience is
maintained. Cisco offers industry-leading performance
through its proprietary IronPort AsyncOS platform, an
enterprise-grade web proxy and cache file system as well as
an intelligent, multi-core engine for rapid content scanning.
Consequently, the Cisco IronPort S-Series is a platform that
can address the capacity requirements of even the largest of
enterprises.
Low Total Cost of Ownership Legacy solutions typically
require multiple appliances or servers to protect against
security, resource and compliance risks. Unlike other
solutions, the Cisco IronPort S-Series provides a single
platform that contains a complete, in-depth defense – along
with all the necessary management tools – significantly
reducing initial and ongoing TCO.
Reduced Administrative Overhead Designed to minimize
administrative overhead, Cisco IronPort web security
appliances offer easy setup and management with an
intuitive graphical user interface, support for automated
updates, and comprehensive monitoring and alerting. The
solution is also easy to deploy and configure to match
corporate-specific policies.
