For many organizations, corporate email is their number one threat vector, as they continue to deal with a seemingly never-ending stream of targeted malicious attachments and URLs. Email is so well suited to attacks that personal webmail, and personal browsing more generally, is now joining corporate email as a major source of compromised accounts and endpoints.
While organizations are protecting access to corporate email systems, employees that fall for a phishing attack through their personal webmail on their corporate laptop, which all too often is accessed off the corporate network and its security controls. Organizations may think that their decision comes down to a classic security vs. usability tradeoff:
Block — Certain website categories may be appropriate for blocking in the workplace (e.g., adult, gambling) however many companies do not have the culture to block ‘webmail’ and ’social media’ categories from their employees.
Allow — Some organizations allow continued access to risk-prone web categories (e.g., webmail, social media), but this exposes them to unnecessary risk for the users and the organization.
But there is a way to allow end users to access what they want while keeping corporate endpoints and credentials safe: web isolation. Using web or browser isolation, organizations can allow their end users to view web content and personal webmail without the associated risk to the business. Browser isolation, while enabling end users access to the services they desire, can ensure that any malicious content that may be present on those websites is unable to infect or impact the corporate device that is being used. In addition, isolation ensures that users can be protected from known phishing sites that they may click on in their personal email.
The opposing forces that operate in many organizations – security concerns and employee experience – are well balanced with this approach. Gartner says, "By 2022, 25% of enterprises will adopt browser isolation techniques for some high-risk users and use cases, up from less than 1% in 2017". (Gartner Innovation Insight for Remote Browser Isolation (gated), Neil MacDonald, March 8, 2018).
