If you want to significantly reduce the attack surface and data breach risks for your organization, zero trust architecture may be the answer. This approach is becoming a priority for global organizations and tech giants like Microsoft<\/a> that seek to reduce cybersecurity risks in their IT environments. It\u2019s no wonder then that 10% of large organizations will have a comprehensive and mature zero trust program in place by 2026, according to Gartner’s predictions<\/a>.<\/p>\n\n\n\n


In this article, we reveal the main components of zero trust network architecture and its practical use cases. You\u2019ll discover the key pros and cons of this cybersecurity approach and learn the most effective ways to implement it.<\/p>\n\n\n\n

Zero trust in a nutshell<\/h2>\n\n\n\n

No one can be trusted by default.<\/em><\/p>\n\n\n\n

First introduced by the Forrester alum John Kindervag in 2009<\/a>, the zero trust approach centers on the idea that trust is a vulnerability and you should \u201cnever trust, always verify\u201d<\/em><\/strong>. Zero trust<\/a> assumes that you need to treat all users as \u201cuntrusted\u201d by default and only grant access to your valuable assets to authenticated and verified users \u2014 and only to the extent needed to perform their particular tasks.<\/p>\n\n\n\n

\u201cZero trust is a security paradigm that explicitly identifies users and devices and grants them just the right amount of access so the business can operate with minimal friction while risks are reduced.\u201d<\/p>\nGartner<\/a><\/cite><\/blockquote>\n\n\n\n

Zero trust is intended to stop both external attacks and insider threats, thus, limiting the potential damage to your organization. <\/p>\n\n\n\n

How does zero trust work?<\/em><\/em><\/p>\n\n\n\n

Zero trust is an architectural approach that requires all users, whether inside or outside your organization’s network, to be authenticated and authorized. You can follow this approach by implementing the principle of least privilege<\/a>, microsegmentation, user activity monitoring<\/a>, and a few other technologies and principles.<\/p>\n\n\n\n

The National Cyber Security Centre<\/a>, for example, offers the following principles for establishing a zero trust architecture:<\/p>\n\n\n\n
