Cisco Cisco Web Security Appliance S190 Guida Introduttiva
At-a-Glance
Powerful, All-in-One Network Security
To combat advanced web security threats, you need strong protection
and consistent control across all endpoints and everywhere in between.
That includes mobile devices, web-enabled and mobile applications,
and web browsers. You need the Cisco® Web Security Appliance. With
it, you can address the challenges of securing and controlling web traffic
easily and quickly.
The Web Security Appliance combines Advanced Malware Protection
(AMP), Cognitive Threat Analytics (CTA), application visibility and control
(AVC), acceptable-use policies, insightful reporting, and highly secure
mobility (Figure 1). It’s all available on a single easy-to-manage platform.
As a physical appliance, the Web Security Appliance has few
maintenance requirements, for low operational costs along with reduced
latency. For highly distributed networks, the Cisco Web Security Virtual
Appliance lets you deploy the same stringent web security when and
where it’s needed in a virtual version.

Protect Roaming Users
The Web Security Appliance protects the data requested by roaming
laptops. Before granting access to the network, it initiates a VPN that
directs sensitive traffic to the primary web access point for real-time
analysis. And by integrating the appliance with the Cisco Identity Services
Engine (ISE), administrators can create policies on the appliance based
on user profile or membership information gathered by engine. You
gain a new level of user control and reporting. You also provide a much
better user experience in bring-your-own-device (BYOD) environments
through streamlined capabilities such as integrated single sign-on.
