    Secure the web with Mimecast web filtering technology

    One in every 13 web requests leads to malware. That fact makes Internet security a business-critical priority for organizations of every size. The web – and DNS, specifically – are involved in 91% of malware attacks. Yet, inexplicably, many organizations don't rely on web filtering technology to monitor their DNS layers. Some organizations are stuck with antiquated legacy systems that can't meet the challenge of an evolving threat landscape, while other companies must deal with disconnected systems that are expensive, complex and resource intensive.

    The challenge of web filtering is compounded by the changing nature of the way employees interact with web resources. Increasingly, users are connecting to the corporate web from home, on the road and from other locations on a variety of devices that are unprotected by firewalls and other perimeter defenses.

    Mimecast Web Security solves this challenge with a cost-effective, cloud-based web filtering service that adds security and monitoring at the DNS layer. With Mimecast's Internet security system, businesses can secure web activity with easy-to-use tools that stop malware and other malicious web activity before it reaches their network or devices.

    How Mimecast web filtering works

    By adding security and monitoring at the DNS layer, Mimecast makes it easy to protect against malicious web activity initiated by user action or malware. When a user clicks a link or enters an address into a browser, a DNS request is sent to Mimecast Web Security to be inspected and resolved. Mimecast scans the target website for potentially malicious content and evaluates the site against any organizational policies for acceptable web use. If the site appears to be safe and acceptable, the user is granted immediate access to it. And if the site is determined to be unacceptable or suspicious, Mimecast blocks the user from accessing it and provides a notification in the browser about why the site was blocked.

    FAQs: What is web filtering?

    What is web filtering?

    Web filtering is a security technology that monitors web activity and prevents users from accessing websites with malicious content or sites that are deemed to be inappropriate for business use.

    How does web filtering work?

    When a user requests a web resource, the web filter technology scans the requested website before resolving the DNS request. If the website is considered safe, the web filter will allow access to the site. And if the scan reveals a malicious or suspicious site, the web filtering technology will block access.

    Why is web filtering important?

    The web is one of the most dominant vectors in cybercrime. Protecting against web-based attacks requires a multi-layered approach to security that involves firewalls, multifactor authentication, antivirus software and regular updates and patches to existing applications. Web filtering adds another highly robust layer of security to help stop malicious activity before it reaches an organization's network or user devices.
