Earlier office spaces looked like a store house of some hardware infrastructure, servers, cables, end user machines, firewalls and security appliances to create traditional data centres which operated within the perimeter of corporate and protected everything inside that space. As organizations started moving their key services and applications over cloud and end users were no longer confined to a particular space or building it became difficult to secure things outside the closed perimeter.\u00a0<\/p>\n\n\n\n<p>\u2018<a href=\"https:\/\/ipwithease.com\/what-is-zero-trust-for-the-cloud\/\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">Zero trust<\/mark><\/a>\u2019 security principles became more relevant as businesses started growing outside the confined boundaries or spaces.<\/p>\n\n\n\n<p>In this article we will learn about how zero trust security is implemented with Cloudflare global network.&nbsp;<\/p><div id=\"ipwit-1326185452\" class=\"ipwit-content ipwit-entity-placement\"><div class=\"ipwit-adlabel\">Google ADs<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-1375203873676133\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-1375203873676133\" \ndata-ad-slot=\"2483378328\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><br style=\"clear: both; display: block; float: none;\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"zero-trust-security\">Zero Trust Security<strong>\u00a0<\/strong><\/h2>\n\n\n\n<p>Moving away from perimeter-based security, \u2018Zero trust\u2019 security focuses on verifying each and every user and device access request and is tightly coupled with the principle of \u2018least privileges\u2019. The \u2018zero trust\u2019 strategy involves implementation of Multi-factor (MFA) authentication, continuous monitoring of environment security. Each principle reduces attack surface, prevents unauthorized access and reduces impact of breaches. However, implementation of \u2018zero trust\u2019 security is a bit challenging due to mixed infrastructure, cultural hurdles and vendor and solution sprawls and cost is one of the major factors here.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"cloudflare-zero-trust-security\">Cloudflare: Zero Trust Security\u00a0<\/h2>\n\n\n\n<p>Cloudflare is a global anycast network sprawl across 300 data centres operating on \u2018zero trust\u2019 security principles. Cloudflare has several components to support \u2018zero trust\u2019 security such as policy engine (Cloudflare zero trust), policy administrator (Cloudflare zero trust), policy enforcement point (cloudflared) and enterprise resources (GCP VM\/ Web applications).&nbsp;<\/p>\n\n\n\n<p>Before we start building&nbsp; a \u2018Zero trust\u2019 security in Cloudflare we have to start setting up the foundation which is the \u2018Asset\u2019.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"asset-inventory\">Asset Inventory<\/h3>\n\n\n\n<p>Taking stock of current assets before building their access mechanism. Mapping physical and virtual infrastructure is essential. How many virtual clouds are there? How do they communicate with each other? How and why do users access those virtual clouds and its services? All access is via console or browser based? Are there public IP addresses for HTTPS or <a href=\"https:\/\/ipwithease.com\/ssh-vs-telnet\/\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">SSH<\/mark><\/a> services? Are resource access permissible over the Internet? Do you have a traditional VPN to allow remote access and how is it gated?\u00a0<\/p>\n\n\n\n<p>Once the list is ready, the next step is to know what you need to protect and rank these services by risk level in the event of security breaches. For example an internal tool is less critical than a customer production database and requires better protection such as access via a corporate device and MFA.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"identity\">Identity<\/h3>\n\n\n\n<p>It is the core of \u2018zero trust\u2019 security. Most customers use a central source for authentication, authorization, validation and logging of actions taken by users. Phishing resistant MFA using physical keys, local authenticator apps, and biometric authentication are valuable tools.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"sso-integration\">SSO Integration<\/h3>\n\n\n\n<p>Single sign on (SSO) solutions offered by directory services help in integrating <a href=\"https:\/\/en.wikipedia.org\/wiki\/Software_as_a_service\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">SaaS applications<\/mark><\/a> and solutions like Okta also offer machine certification as part of authentication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"third-party-access\">Third Party Access<\/h3>\n\n\n\n<p>Zero trust solutions need to identify identities beyond which are not owned by you such as third-party service providers or suppliers.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"800\" height=\"454\" data-id=\"34293\" src=\"https:\/\/ipwithease.com\/wp-content\/uploads\/2025\/05\/Cloudflare-Zero-Trust-Security.jpg\" alt=\"Cloudflare Zero Trust Security\" class=\"wp-image-34293\" title=\"\" srcset=\"https:\/\/ipwithease.com\/wp-content\/uploads\/2025\/05\/Cloudflare-Zero-Trust-Security.jpg 800w, https:\/\/ipwithease.com\/wp-content\/uploads\/2025\/05\/Cloudflare-Zero-Trust-Security-768x436.jpg 768w, https:\/\/ipwithease.com\/wp-content\/uploads\/2025\/05\/Cloudflare-Zero-Trust-Security-300x170.jpg 300w, https:\/\/ipwithease.com\/wp-content\/uploads\/2025\/05\/Cloudflare-Zero-Trust-Security-600x341.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"where-does-cloudflare-fit-in\">Where does Cloudflare fit in?<\/h2>\n\n\n\n<p>Cloudflare simplifies your network architecture acting as a single point of enforcement of identity for your applications and services, networks, developer services and SaaS applications.
