Cisco Web Security Appliance S390
Simple Installation, Easy Management, and Powerful Protection for Your Web Infrastructure.

Features and Benefits:

Talos Security Intelligence

Receive fast and comprehensive web protection backed by the largest threat detection network in the world, with the broadest visibility and largest footprint, including:

• 100 TB of security intelligence daily
• 1.6 million deployed security devices, including firewall, IPS, web, and email appliances
• 150 million endpoints
• 13 billion web requests per day
• 35% of the world's enterprise email traffic

Providing a 24x7 view into global traffic activity to analyze anomalies, uncover new threats, and monitor traffic trends. Talos prevents zero-hour attacks by continually generating new rules that feed updates to the WSA every three to five minutes, enabling industry-leading threat defense hours and even days ahead of competitors.

Secure Web Appliance Usage Controls

Combine traditional URL filtering with dynamic content analysis to mitigate compliance, liability, and productivity risks. Cisco's continuously updated URL filtering database of over 50 million blocked sites provides exceptional coverage for known websites, and the Dynamic Content Analysis (DCA) engine accurately identifies 90 percent of unknown URLs in real time; it scans text, scores the text for relevancy, calculates model document proximity, and returns the closest category match. Administrators can also select specific categories for intelligent HTTPS inspection.

Advanced Malware Protection

Advanced Malware Protection (AMP) is an additionally licensed feature available to all Cisco WSA customers. AMP is a comprehensive malware-defeating solution that enables malware detection and blocking, continuous analysis, and retrospective alerting. It takes advantage of the vast cloud security intelligence networks of both Cisco and Sourcefire® technology. AMP augments the malware detection and blocking capabilities already offered in the Cisco WSA with enhanced file reputation capabilities, detailed file-behavior reporting, continuous file analysis, and retrospective verdict alerting. The Cisco AMP Threat Grid delivers malware protection through an on-premises appliance for organizations that have compliance or policy restrictions on submitting malware samples to the cloud. The Layer 4 Traffic Monitor continuously scans activity, detecting and blocking spyware ”phone-home” communications. By tracking all network applications, the Layer 4 Traffic Monitor effectively stops malware that attempts to bypass classic web security solutions. It dynamically adds IP addresses of known malware domains to its list of malicious entities to block.

Cognitive Threat Analytics

Cisco Cognitive Threat Analytics is a cloud-based solution that reduces time to discovery of threats operating inside the network. It addresses gaps in perimeter-based defenses by identifying the symptoms of a malware infection or data breach using behavioral analysis and anomaly detection. Take advantage of Cisco Cognitive Threat Analytics with a simple add-on license to your Web Security solution. Reduce complexity while gaining superior protection that evolves with your changing threat landscape.

Application Visibility and Control (AVC)

Easily control the use of hundreds of Web 2.0 applications and 150,000+ micro-applications. Granular policy control allows administrators to permit the use of applications such as Dropbox or Facebook while blocking users from activities such as uploading documents or clicking the ”Like” button. The WSA supports visibility of activity across an entire network. New: Customers can deploy customized bandwidth and time quotas per user, per group, and per policy.

Data Loss Prevention (DLP)

Prevent confidential data from leaving the network by creating context-based rules for basic DLP. The Cisco WSA also uses Internet Content Adaptation Protocol (ICAP) to integrate with third-party DLP solutions for deep content inspection and enforcement of DLP policies. The Cisco WSA also supports Secure ICAP to encrypt the traffic exchanged between WSA and third-party DLP solutions.

Remote Browser Isolation (RBI)

By isolating web traffic from the user device and the threat, the Secure Web Appliance RBI delivers an extra layer of protection to the Secure Web Appliance so that users can safely access risky websites without the risk of malware infections. With RBI, the Secure Web Appliance isolates web content in a remote surrogate browser in the cloud, separate from the endpoint and the corporate network, and renders it safely to the end user providing a seamless end user experience.

Roaming-User Protection

The Secure Web Appliance protects roaming users by integrating with the Cisco AnyConnect Secure Mobility Client, which provides Secure Web Appliance to remote clients by initiating a VPN tunnel that redirects traffic back to the on-premises solution. Cisco AnyConnect technology analyzes traffic in real time prior to permitting access.

The Secure Web Appliance is also integrated with Cisco Identity Services Engine (ISE). With this exciting enhancement, customers can now take advantage of the power of Cisco ISE for Secure Web Appliance upon request. Cisco ISE integration allows admins to create policy on the Secure Web Appliance based on profile or membership information gathered by Cisco ISE through its single sign-on process.

Centralized Management and Reporting

Receive actionable insights across threats, data, and applications. The Secure Web Appliance provides an easy-to-use, centralized management tool to control operations, manage policies, and view reports.

The Cisco M-Series Content Security Management Appliance provides central management and reporting across multiple appliances and multiple locations, including virtual instances.

Cisco Advanced Secure Web Appliance Reporting is a reporting solution that rapidly indexes and analyzes logs produced by Secure Web Appliance and Cisco Umbrella. This tool provides scalable reporting for customers with high traffic and storage needs. It allows reporting administrators to gather detailed insight into web usage and malware threats.

Deployment:

The Cisco WSA is a forward proxy that can be deployed in either Explicit mode (proxy automatic configuration [PAC] files, Web Proxy Auto-Discovery [WPAD], browser settings) or Transparent mode (Web Cache Communication Protocol [WCCP], Policy-Based Routing [PBR], load balancers). WCCP-compatible devices, such as Cisco Catalyst® 6000 Series Switches, Cisco ASR 1000 Series Aggregation Services Routers, Cisco Integrated Services Routers, and Cisco ASA 5500-X Series Next-Generation Firewalls, reroute web traffic to the Cisco WSA.

The Cisco WSA can proxy HTTP, HTTPS, SOCKS, native FTP, and FTP over HTTP traffic to deliver additional capabilities such as data-loss prevention, mobile user security, and advanced visibility and control.

Licenses:

A Cisco WSAV license is included in all Cisco Web Security software bundles (Cisco Web Security Essentials, Cisco Web Security Antimalware, and Cisco Web Security Premium). This license has the same term as the other software services in the bundle and can be used for as many virtual machines as needed.

Term-Based Subscription Licenses

Licenses are term-based subscriptions of one, three, or five years.

Quantity-Based Subscription Licenses

The Cisco Web Security portfolio uses tiered pricing based on a range of users, not devices. Sales and partner representatives can help to determine the correct sizing for each customer deployment.
