Cisco® Cloud Web Security is a different, more comprehensive, cloud-delivered web defense solution. It provides industry-leading, real-time protection and thorough enforcement of web-usage policies.
Hacking has become a recognized industry, supporting sophisticated and well-funded criminal enterprises. Attacks are also evolving continually, becoming more damaging and harder to detect. Traditional web security methods can block known threats but are not able to adapt to the changing threat landscape. And they can't handle advanced malware.
Perimeter defenses don’t address how your users access information and resources. Now it isn’t just people outside your organization who are of concern; your own users may consume excess bandwidth or access inappropriate content that can put your organization at risk. Their personal devices may introduce malware from inside the firewall.
Built on an industry-leading global threat-visibility network, Cloud Web Security offers highly effective protection against advanced and targeted threats. It continuously monitors both network and file behavior. It identifies threats operating in the environment with Cisco Advanced Malware Protection (AMP) and Cognitive Threat Analytics.
Cloud Web Security controls web usage and blocks sites based on signature, reputation, and content analysis. It also delivers best-in-class malware scanning through outbreak intelligence, a heuristics-based engine that analyzes each webpage component in real time to block threats.
Cisco AMP protects against advanced malware threats, using file retrospection to track a file’s disposition over time. Cognitive Threat Analytics continuously scans for symptoms of a breach, reducing the time to discover threats that bypass perimeter defenses.
As a cloud service, Cloud Web Security delivers superior flexibility. You can easily deploy and scale the service with multiple connection options while using the existing infrastructure. A single management interface provides global control, providing enforcement of detailed web-usage policies across an entire organization no matter where users are located or on what device. Through the Cisco AnyConnect®Secure Mobility Client, Cloud Web Security extends its strong protection to roaming laptop users and enforces the same on-premises policies.
Our advanced global threat visibility network continually updates Cloud Web Security against the latest threats, and the most actionable cloud-delivered intelligence reporting helps ensure superior visibility into web usage. Top-tier data center facilities in 23 locations around the globe deliver a service-level agreement (SLA) of 99.999 percent uptime, so that information is always available. Cloud Web Security also comes with Cisco’s award-winning 24-hour support.
Features and Benefits by License
Several licenses are available. Cloud Web Security Essentials is the base offering for new and renewing customers. Other bundles and individual options are also available. The major features of each license are described in Tables 1 through 5.
Table 1. Essentials License
Control web access to more than 50 million known websites by applying filters from a list of over 75 web categories.
Increase the catch rate with an intelligent multiscanning technology that divides web traffic into functional elements and efficiently analyzes it in real time.
Identify unknown and unusual behaviors and zero-hour outbreaks through a heuristics-based antimalware engine. Outbreak intelligence runs webpage components in a virtual emulation environment before permitting user access. Using proprietary “scanlet” engines for Java, PDF, executables, and more, outbreak intelligence opens up the individual components of a webpage to determine how each component behaves and blocks any malware.
Restrict website access based on site reputation. Analyze data such as the domain owner, the hosting server, the time created, the type of site requested, and more than 50 other distinct parameters to provide a reputation score for the site requested.1
Application visibility and control
Increase employee productivity by controlling access to webpages, individual web parts, or microapplications so that employees can access the sites needed for work without unnecessary distractions. Simultaneously prevent access to inappropriate content.
Dynamic content analysis
Defend against compliance, liability, and productivity risks by combining traditional URL filtering with real-time dynamic content analysis (DCA). The DCA engine automatically categorizes the content of an unknown URL by analyzing the content of the page itself, scoring relevancy to web categories (such as pornography, hate speech, gambling, and illegal downloads) and blocking the page if it conflicts with web security policies.
Centralized management and reporting
Receive actionable insight across threats, data, and applications. A powerful centralized tool controls both security operations (such as management) and network operations (such as analysis of bandwidth consumption). Administrators have access to a variety of predefined reports and can create customized dashboards and set notifications. All reports are generated and stored in the cloud, so they are delivered in seconds as opposed to hours. Reports can be also be saved and scheduled for automated delivery. These capabilities provide flexibility, offering detail down to the user level, and help enable administrators to spotlight potential issues quickly.
Roaming laptop user protection
Protect roaming users with the same in-house policies through Cisco AnyConnect. AnyConnect routes all roaming web traffic through an SSL tunnel directly to the closest Cisco cloud proxy and enforces the same security features that are on premises. By eliminating the need to backhaul web traffic through VPN, Cloud Web Security relieves web congestion at the headquarters, reducing bandwidth use while improving the end-user experience.
The Cloud Web Security Premium license, shown in Table 2, includes all the features from the Cloud Web Security Essentials bundle and adds AMP and Cognitive Threat Analytics.
Table 2. Premium License
(also available separately)
Protect against the latest and most advanced forms of malware with AMP’s detection and blocking, continuous analysis, and retrospective alerting. AMP uses the vast cloud security intelligence networks of both Cisco and Sourcefire (now part of Cisco). AMP augments the antimalware detection and blocking capabilities already offered in Cloud Web Security with enhanced file reputation capabilities, detailed file sandboxing, and file retrospection.
The only solution with all of these capabilities, Cisco AMP tracks a file’s disposition over time inside the network perimeter. If a file is later found to be malicious, file retrospection identifies where the file entered and where it traveled to help in the remediation process. Learn more.
Cognitive Threat Analytics
(also available separately)
Reduce the time to discovery of threats operating inside the network. Cognitive Threat Analytics addresses gaps in perimeter-based defenses by identifying the symptoms of a malware infection or data breach using behavioral analysis and anomaly detection. Unlike traditional monitoring systems, it relies on advanced statistical modeling and machine learning to independently identify new threats, learn from what it sees, and adapt over time. Learn more.
Table 3. Advanced Threat Detection and A la carte Licenses
Log extraction API
Automatically pull web-usage data quickly for highly secure analysis with an S3-compatible HTTPS API. Log data is compiled in W3C text format that can be correlated with existing data using a variety of reporting and analysis tools such as security information and event management (SIEM). Log information consisting of more than 20 attributes is typically available within 15 minutes of the event. Log extraction can be added to any existing Cloud Web Security license. It is ideal for customers with 4000 seats or more.
See Table 2.
Cognitive Threat Analytics
See Table 2.
Data for blocked web requests (policy or malware blocks) is retained for one year, and allowed data is retained for 45 days. Customers can retain data for longer periods to match the terms of their subscription.
Advanced threat detection is an add-on license that includes Cisco AMP and Cognitive Threat Analytics (see descriptions in the tables above) and is available to customers with a current Cloud Web Security Essentials license.

Cloud Web Security Traffic Redirection Connection Methods
Cloud Web Security allows for flexible deployment options that include Cisco appliances... or not. There are many ways to redirect traffic to the Cloud Web Security web proxy. Redirection can be accomplished through the Cisco Adaptive Security Appliances (both physical and virtual), Cisco Integrated Services Routers (ISR) G2, Cisco 4000 Series Integrated Services Routers (through generic routing encapsulation over IPsec) and the Web Security Appliances (physical and virtual). These redirect traffic to Cloud Web Security for web security functions.
Next-Generation Firewall (Cisco Adaptive Security Appliances, physical and virtual): Capitalize on your Adaptive Security Appliance investments by offloading content scanning to Cisco’s cloud through Cloud Web Security. Apply acceptable-use policy to the company, groups, or individual users.
Web Security Appliance (physical and virtual): Integrate Cloud Web Security and the Web Security Appliance so that identity information can be sent to the cloud. And extend other on-premises enterprise features to Cloud Web Security customers.
Cisco ISR G2: Save bandwidth, money, and resources and improve Internet speed at the branch by intelligently redirecting Internet traffic from branch offices directly to the cloud to enforce security and control policies. Apply acceptable-use policy to all users regardless of location.
Cisco 4000 Series ISR: Get the same benefits of redirecting through the ISR G2. At the same time, you reduce maintenance costs by adopting industry-standard GRE over IPsec technology that is reliable, well understood, and mature. See Controlled Availability notification for more information
AnyConnect Secure Mobility Client: Authenticate and redirect web traffic off the corporate network whenever the end user is. Cloud Web Security uses cached user credentials and directory information when users are away from the office or connecting through a VPN, helping to ensure that the same web usage policies are applied.
Standalone deployment: Deploy a simple web security solution that does not require additional hardware. Connect to the Cloud Web Security service using existing browser settings and Proxy Auto-Configuration (PAC) or Web Proxy Auto-Discovery (WPAD) files.
Every Cloud Web Security deployment option includes directory authentication methods that enhance end-user identification, enabling administrators to apply precise filter controls at the user or group level and run detailed log reports.
All Cisco Cloud Web Security subscriptions are term-based subscriptions of 1, 3, or 5 years.
The Cisco Web Security portfolio uses tiered pricing based on the number of users, not devices. Sales and partner representatives can help to determine the correct tier for each customer deployment.
