Cloud Web Security


    Essential cloud web security to keep you protected

Protect your employees from malicious websites and applications with a fully cloud-based solution.

    The Challenge

    The challenges and risks of working online 

    Today’s hybrid work surface has solidified web and email as cybercriminals’ preferred vectors for launching attacks. And the target couldn’t be any larger. For countless employees, work consists almost entirely of these two tools.

    The web in particular presents a massive risk to security leaders if left unchecked. Malicious content is everywhere, scattered across popular social media sites, web-based email, and file sharing platforms.

    On the internet, the line between work and personal life is decidedly blurred. People have thousands of cloud applications at their fingertips, many of them a mystery to security teams. Employees, contractors, and Wi-Fi guests alike represent real risk that needs to be addressed.

    Web Security FAQs

    What are the features of the best web security solutions?

    The best web security solutions provide robust protection for your employees while minimizing the operational impact on your security team.

    Best-in-class solutions should include granular policy and reporting capabilities as well as monitoring and control for cloud applications. On and off-network protection and easy administration are also key.

    DNS-based solutions protect against malware, viruses, and spyware, and can also provide a cloud-based proxy for sophisticated threats. For many organizations, DNS-based solutions provide the best alternative to secure web gateway (SWG) solutions which tend to be expensive and complex.

    Why do you need a security solution?

    Web security offers proactive protection against a variety of threats to safeguard employees and productivity. It offers an effective solution and layered defense against common attacks – like account compromise or malware injection – before they touch any critical systems.

    How do I choose the best website security service for my business?

    Web security should work in partnership with your broader security strategy. Identify areas of risk within your organization and consider what requirements will drive your risk mitigation tactics – including acceptable web use and cloud application monitoring and control.

    Additionally, with web and email representing the two most prominent attack vectors, and often being used in concert during attacks, web security should work in cooperation with email security through integration. This combined effort will also help to offset operational costs and complexity.
