A web security solution provides comprehensive visibility and granular control over traffic heading for the Internet.
FREMONT, CA: Web security is enforced by the employment a security appliance that serves as a web proxy, acting as the intermediary between users and the Internet. This appliance can be on-premises or in the cloud, or it can be software that runs within the user's web browser. Nevertheless, it is sufficient that an employee's computer is configured to route all Internet-bound traffic through the web security system.
Due to its presence between a web user and the Internet, the web security solution has high visibility and control over web traffic. At the application layer, all traffic passing through it can be examined for harmful content or behaviors that violate business policy. Approved traffic may proceed to its intended destination, while all other traffic may be discarded.

An online security solution should protect consumers from a broad range of web-related cyber risks. Several critical features of a web security system include the following:
URL Filtering: Cybercriminals employ a range of known-bad URLs in their phishing attempts and malware distribution. URL filtering enables administrators to prevent users from viewing these and other known harmful and unsuitable websites and impose bandwidth restrictions on certain types of websites.
Application Control: Web security solutions inspect traffic at the application layer, which means they have visibility into the application that generates the traffic and its data. This granular visibility enables web administrators to set application-specific rules that ensure appropriate control of access to applications and sensitive data both within and outside the business.
Data Loss Prevention: Sensitive and proprietary data can be exfiltrated in various methods, incurring considerable expenses for a firm. Data loss prevention (DLP) solutions continuously monitor data flows to detect and prevent sensitive and essential data leaks.
Antivirus: Malicious websites are a significant route for malware distribution, including ransomware, trojans, and information stealers. A web security solution's antivirus will analyze all traffic passing through it to determine whether it contains known malware samples characterized by unique signatures.
SSL Introspection: A growing percentage of web traffic is encrypted using HTTPS, protecting the traffic from eavesdropping. SSL introspection enables security solutions within an enterprise to analyze encrypted web traffic, allowing them to detect and prevent harmful content and data exfiltration.
The web may be dangerous, posing severe hazards to an organization's reputation and employees. To provide adequate protection against various attacks, a web security solution must have diverse capabilities.
