Why large corporations choose WordPress in 2026: An enterprise analysis

The boardroom question about WordPress has changed over the last decade. Few large organisations still ask whether an open-source CMS can carry a corporate website. They ask which parts of their portfolio belong on it, who will host it and how the editorial teams will work once it is live.

For years, large corporations stayed on monolithic, proprietary CMS platforms partly because a high licence fee felt like a guarantee. Today the arguments that decide a CMS choice are editorial speed, performance, the size of the hiring pool and how easily the platform can be replaced or extended. Those are the arguments where WordPress is strongest.

This analysis walks through those reasons with named organisations and public sources: the market data, the companies that documented their moves, the security and compliance record, and the places where WordPress needs more engineering than its reputation suggests.

#How many websites use WordPress in 2026

W3Techs, which updates its reports daily, reports that WordPress is used by 58.5% of all websites whose content management system is known, which is 40.0% of all websites (W3Techs, 14 October 2026). The same report shows how quickly the installed base moves to new major releases: on that date 65.7% of WordPress sites ran version 7, 27.4% version 6 and 4.8% version 5.

WordPress.org’s own security page uses a different figure, more than 43% of the web (WordPress.org, Security). The difference comes from the moment and the method of measurement, so when a procurement document quotes a market share, it should name the source and the date next to the number.

For an enterprise buyer, the share matters for two practical reasons. A platform used by that many sites has a large supply of developers, agencies, hosting companies and security vendors. And a large installed base means vulnerabilities are looked for, found and fixed in public, which is the opposite of the security-through-obscurity model of a niche CMS.

#Which large companies use WordPress

The list below contains only organisations whose WordPress use is documented by a public source: the WordPress.org Showcase, the WordPress.org enterprise case studies, or WordPress VIP’s published case studies.

The case study PDFs are linked from the WordPress.org enterprise page and were written by the agencies that delivered the projects (Human Made for Siemens and Capgemini, Inpsyde for SAP). They describe each project from the vendor’s side, so read them as documented examples, not as independent audits.

#WordPress vs Sitecore for marketing teams

In a fast-paced market, a corporation’s greatest enemy is latency in communication.

• The proprietary problem: in systems like Sitecore or Adobe AEM, even minor layout changes often require a ticket to a specialised IT team and a deployment cycle.
• The WordPress solution: with the maturity of block-based editing (Gutenberg), marketing teams can build, test and launch complex landing pages from patterns and reusable blocks without waiting for a release.

This marketing agility allows brands to respond to market trends or global events without technical bottlenecks.

#What Siemens gained by leaving Adobe Experience Manager

Siemens is the clearest documented example of this argument. Its Ingenuity platform, where Siemens employees around the world publish under their own names, was originally built on Adobe Experience Manager. According to the Siemens case study, the move to WordPress made custom development much quicker, and the money saved went into building the features the team needed. The same platform later became a virtual events platform, launched in three months.

The case study also describes the multilingual problem that pushed the change. The original site was English only. Audience interest, legal requirements in Germany and the global nature of the business required more languages. Siemens now uses AWS to translate English and German content automatically, editors correct the translations, and every language version gets its own URL.

#Moving from Drupal to WordPress at enterprise scale

Capgemini, a technology consultancy present in over 40 countries, launched a series of websites on Drupal 7 in 2012. The Capgemini case study says the Marketing and Communications team hit blockers at almost every stage of publishing, and the lack of backwards compatibility between Drupal versions made the sites increasingly unstable.

The detail that matters most for a CIO is the staffing one. Capgemini has 200,000 people, and the case study notes that there were fewer than five qualified Drupal webmasters in the organisation. The recruitment team, which publishes job roles for tens of thousands of applicants a year, could not keep up. Capgemini moved its network of 38 sites to WordPress, with the goal of letting local teams publish while staying within the corporate brand.

That is a talent-pool argument, not a feature argument. A CMS that only a handful of people inside the company can operate is a key-person risk, however good its feature list looks.

#Headless WordPress and Core Web Vitals at enterprise scale

Google’s ranking systems reward good page experience, and Core Web Vitals (LCP, INP and CLS) are part of that assessment.

• Lightweight by design: proprietary enterprise systems are often heavy. WordPress, when optimised correctly, can be fast.
• Headless capabilities: large programmes keep WordPress as the authoring plane while Astro or similar edge-friendly front ends stream HTML with aggressive caching. LCP depends on images, fonts and third-party scripts far more than on the CMS, so these have to be budgeted deliberately.

#How Al Jazeera runs headless WordPress

Al Jazeera’s newsroom has more than 70 bureaus around the world and more than 10 channels and divisions. Before consolidating, its global teams worked across more than six different CMSes, including more than three versions of Drupal (WordPress VIP case study).

The new stack has three layers: WordPress as the editorial back end, a GraphQL query layer in the middle and a React-based application on top. GraphQL gives every front end a standard way to request content. The first application built on it was the AJ Alpha mobile app, and the architecture has since been extended across Al Jazeera’s channels. WordPress support for bidirectional languages made Arabic and Chinese editions possible on the same platform.

The pattern is useful beyond news. One editorial back end feeds several front ends (web, apps, partner feeds) through an API, and each front end can be rebuilt without migrating the content.

#How much traffic can WordPress handle

The usual objection from IT is scale. Two documented cases answer it.

TIME.com moved to WordPress and WordPress VIP in 2015, replacing a legacy publishing system that its team described as dated and inflexible. When Taylor Swift was named Person of the Year, the site handled more than 100,000 requests per second at peak, according to the WordPress VIP case study. More than 100 TIME.com staff publish with the block editor, custom blocks and reusable patterns.

WhiteHouse.gov has run on WordPress since 2017. The WordPress.org Showcase entry describes the 2021 rebuild led by 10up with Wide Eye Creative, launched on Inauguration Day, with layered caching, a global CDN and auto-scaling to absorb traffic spikes. The same entry notes that WordPress has been used across three administrations.

In both cases the scale comes from the hosting architecture (page caching, object caching, CDN, horizontal scaling), not from WordPress alone. A self-hosted WordPress on a single server will not behave like either of them.

#Enterprise CMS cost compared with WordPress

For a large company, an annual CMS licence may look small next to its total IT budget, but the hidden costs are larger than the licence.

• Implementation cost: proprietary systems need specialised integrators, and the initial build is often expensive.
• Support cost: you are locked into a small pool of high-priced specialised agencies.
• Incremental innovation: in WordPress, thousands of contributors improve the software in public, at no licence cost. In proprietary systems, you wait for the vendor’s next paid upgrade.

WordPress itself has no licence fee. The WordPress.org enterprise page states that the source code “is made freely available and may be distributed and modified subject to the GPL license”. The costs move to hosting, development, support and editorial training, which are the line items that should go into a five-year comparison.

The White House move is one of the few public cost statements. The Showcase entry cites an administration official telling the Washington Examiner that the 2017 redesign would save taxpayers nearly $3 million per year. That figure is the administration’s own estimate, reported by the press, so it supports the direction of the argument rather than a precise saving for any other organisation.

#Is WordPress secure enough for enterprises

The idea that open source is less secure does not survive a look at how WordPress handles vulnerabilities. Its transparency is part of its security model.

• Active auditing: the source code is public, the WordPress Security Team develops fixes for responsibly disclosed vulnerabilities and releases them in bugfix releases.
• High-profile validation: WhiteHouse.gov and NASA run on WordPress, and with the right environment hardening, WordPress meets the requirements of government and enterprise security reviews.

#What the WordPress Security Team does

According to WordPress.org, the core development lifecycle includes code review throughout, with contributions reviewed by trusted committers. The Security Team includes more than 50 trusted experts, among them lead developers, security researchers and key contributors to every component of WordPress, plus sponsored members. It hardens the software against threats such as the OWASP Top Ten.

Two policies matter for enterprise planning. Only the latest version of WordPress is officially supported. The Security Team backports fixes to older versions as a courtesy, so older sites can receive critical fixes through auto-updates, but an enterprise should not plan around that courtesy. The team also works directly with large hosting companies and security providers to coordinate releases and build web application firewall mitigations.

Plugins and themes are where most risk sits. WordPress.org asks researchers to report plugin vulnerabilities to the plugin developer and the Plugins Team. In an enterprise build, that means every plugin needs an owner, a review before installation and a plan for when it stops being maintained.

#How Ubisoft got a WordPress intranet through security review

An intranet is a harder security case than a public website, because it holds confidential information. Ubisoft built its global intranet on WordPress VIP to replace fragmented internal tools: some locations had no intranet at all, others used local tools. The WordPress VIP case study says that any global intranet had to pass security review quickly, and that Ubisoft’s security team signed off after up-front testing. One of the stated reasons is that the company works on unreleased games and secret projects.

#Is WordPress approved for government use

In the United States, cloud services used by federal agencies need a FedRAMP authorisation. WordPress VIP, the enterprise hosting platform from Automattic, first achieved a FedRAMP Authority to Operate in 2021 and announced a FedRAMP Moderate authorisation on 8 April 2025 (WordPress VIP). The announcement names WhiteHouse.gov, NASA and the U.S. Department of Veterans Affairs as government websites already on the platform.

The authorisation belongs to the hosting platform, not to WordPress as software. The same distinction applies in Europe: compliance with NIS2, GDPR or a sector regulator is a property of the hosting, the processes and the configuration around WordPress. When a vendor claims compliance, ask which entity holds the certificate and what scope it covers.

#WordPress Multisite for managing multiple brands

Large corporations don’t just have one website; they have a portfolio.

• Multisite network architecture: WordPress allows a corporation to manage hundreds of localized sites (for example brand-pl.com and brand-de.com) from a single dashboard.
• Shared assets: themes and plugins are updated across the network, so brand consistency does not depend on each regional team.

#How SAP runs its news centre on WordPress Multisite

The SAP News case study describes a Multisite network serving 44 languages, with 21 websites designed differently for individual brands. The SAP News Center publishes articles, press releases, videos and broadcasts from a centralised WordPress back end, which consolidates content management and technical administration while each site keeps its own design and functionality.

This is the practical answer to the “global versus local” problem: central control over code, security and updates, local control over content and, where needed, design.

#Multilingual WordPress for regional markets

WordPress has no built-in multilingual layer, so multilingual networks rely on Multisite (one site per language) or plugins such as WPML or Polylang. Each approach gives every language version its own URL, which is what search engines need for hreflang. Siemens adds machine translation with human editing on top, as described above. The choice between them depends on whether regional teams need separate editorial control.

#Hiring WordPress developers and avoiding vendor lock-in

The most dangerous risk for a corporate project is key person dependency.

• If your site is built on an obscure proprietary CMS and your only specialised developer leaves, your digital estate is at risk. Capgemini’s fewer than five Drupal webmasters for 200,000 people is the documented version of that risk.
• WordPress has one of the largest pools of developers, agencies and hosting companies of any CMS. There is no official WordPress certification, so evaluate partners by their published work and code, not by a badge. Because the software is licensed under the GPL, a corporation can change agency or host and keep its code and content.

#Integrating WordPress with Salesforce, ERP and AI

WordPress is often the content hub of a composable stack. Its integration story rests on the REST API, which is part of core.

The WordPress REST API Handbook describes it as an interface for applications to send and receive data as JSON objects, and as the foundation of the block editor. It applies the same authentication rules as the site: public content is generally available through the API, while private content, password-protected content, internal users, custom post types and metadata require authentication or explicit configuration.

That API-first approach means WordPress can connect to:

• Salesforce and CRM systems: lead flow and customer personalisation.
• ERP systems: logistics and pricing data pushed to the front end.
• AI services: language models for summarisation and translation, as in the Siemens translation workflow.

#Enterprise WordPress migration case study

In late 2025, a large tech firm migrated 40 regional sites from a proprietary DXP to Enterprise WordPress. The firm is not named and the results below are its own, so treat them as reported rather than measured by us:

• Result 1: publishing a new regional page went from a multi-day release cycle to the same working day.
• Result 2: page load improved across all regions, most visibly outside the origin continent.
• Result 3: annual licensing and specialised support costs went down.

#Is WordPress future-proof for AI search

The web is moving toward static-first and AI-first experiences. WordPress’s modular block system fits these trends. It structures content in a way that can be parsed by both human readers and AI agents (Perplexity, ChatGPT), which helps corporate expertise stay discoverable in answer engines.

WordPress VIP’s Pew Research Center case study reports increased visibility in LLM answers after Pew’s largest release. It is a vendor case study. Visibility in AI answers depends on the content and its structure more than on the CMS.

The documented moves to WordPress share the same drivers: Siemens left AEM for editorial speed and lower custom development cost, Capgemini left Drupal 7 because almost nobody inside the company could operate it, SAP needed 44 languages under one back end, and Al Jazeera needed one content source for many front ends. WordPress gives large organisations the flexibility of a custom build with the maintenance advantages of a large open-source ecosystem.

Large corporations have stopped buying CMS “software” and evaluate CMS ecosystems instead: integrations, developer availability, editorial workflow, security controls and ownership.

For an enterprise CMS decision, write down the governance model, integration list, security requirements and publishing workflow before choosing the platform. Then check hosting compliance, plugin ownership and the upgrade policy, because those decide whether WordPress works at your scale.
