    What is a Web Security Gateway?

    A web security gateway, also known as a secure web gateway, is a device, cloud service, or application that is deployed at the boundaries of a network to monitor and stop malicious traffic from entering the organization, and to block users from accessing malicious or suspicious web resources. Standard features of a web security gateway may include URL filtering, virus and malware code detection, data leak prevention, CASB, and other application level control.

    Secure web gateways are essential to thwart cybercriminals who have grown adept at web impersonation, websites that appear to be authentic, but in fact are fake. The purpose of these fake sites is to dupe unsuspecting users to click on a malicious link and/or disclose personal information. Examples include bogus shopping, business, and financial sites.

    How Does a Secure Web Gateway Work?

    A secure web gateway acts just as the name implies: web traffic to and from a network must first pass through a gate that checks for malicious code, suspects URLs, and other potential threats. The gateways also block unapproved uploads to cloud services as well as prohibited data.

    A secure web gateway can also provide additional controls such social media filtering, document scanning, and anti-malware integration for zero-day (never seen before) threat detection.

    Organizations Need a Superior Web Security Gateway Service

    When it comes to cybersecurity, the web continues to be a dangerous place. More than 90% of successful malware incidents today use the web and DNS specifically to breach defenses and launch attacks. With one of every 13 web requests leading to some form of malware, it's imperative that organizations deploy a web security gateway.

    Few organizations, however, implement adequate protections and many organizations aren't monitoring their DNS layers at all. For some, the DNS security solutions are too expensive and complex, while others are saddled with a collection of disjointed security solutions that are resource-intensive and hard to manage. And few legacy or on-premises systems can adapt quickly enough to respond to web security threats emerging from a rapidly evolving security landscape.

    Mimecast offers a solution: an easy-to-use, cloud-based web security gateway service that reduces the cost and complexity of securing the DNS layer while providing comprehensive protection to keep the web safe.

    Secure Web Gateway FAQs

    How Secure Web Gateways are Different from Firewalls?

    A firewall sets rules to govern data that enters or leaves a network so as to restrict or prevent unauthorized access. Generally speaking, It’s a basic form of protection that while it has developed a more extensive feature set, does not provide the same robust level of threat protection as a secure web gateway, nor does it have the same range of reporting features.

    A secure web gateway monitors, inspects, and prevents suspicious traffic from entering or leaving an organization’s network; this includes  URL filtering, data leakage prevention, malware code protection and control.

    What are the Best Practices for Web Security Gateways?

    Web security gateway best practices include the ability to:

    • Protect anytime and anywhere no matter where users are located.
    • Provide an Integrated, cloud-based solution that protects the top two cyberattack vectors, email and the web.
    • Deploy quickly, in less than 60 minutes.
    • Provide cost-effective protection.
    • Manage administration from a single, cloud-based console, to enable IT administrators to consistently apply security policies throughout the organization, and to simplify administration by automatically applying policy configurations, directory synchronization, user accounts, roles and permissions, branding and audit reporting to email and web security.
