Companies Using Azure Front Door

Two thirds of this list has nothing else Microsoft on it

The most useful number on this page is a co-occurrence. Only 33.18% of the 48,175 domains where Azure Front Door answers also carry a Microsoft Azure platform signal. Two in three do not. Whatever is running behind the edge on those domains, we cannot see a Microsoft platform underneath it.

That is not the shape I expected before running it. The intuitive model of a cloud edge is that it ships with a platform decision: you put the application on the platform, then you put the platform vendor's edge in front. On this evidence that is the minority case. Azure Front Door is being bought on its own, as a global edge and web application firewall pointed at an origin that lives somewhere else, and somewhere else is usually not Microsoft.

It also settles how these two pages relate to each other. Our Microsoft Azure platform profile counts 175,651 domains on a different set of signals, nameserver delegation and platform headers, which describe where an application is hosted. This page describes what answers the browser. 48,175 is not a slice you can carve out of 175,651, because two thirds of it was never inside 175,651 to begin with. If you want the mechanics of how a signal like this is read, we wrote up the detection methods behind it.

Two in three domains behind Azure Front Door show no Microsoft platform underneath. The edge is the thing being bought, not a by-product of a platform decision.

Three hyperscaler edges, and a leader nobody buys

Azure Front Door ranks 4th of the 12 technologies in Load Balancers & Proxies on 15.75% share. The ranking overstates the row above it and understates the row beside it, so both need saying.

Envoy leads on 111,282 domains and 36.39%, and Envoy is not a competitor in any commercial sense. It is an open-source proxy teams deploy themselves, and it turns up inside service meshes and inside other vendors' products. Calling it the category leader is accurate about deployment and misleading about purchase. The comparisons worth making are with the two edges bought the same way this one is.

Those three sit closer together than a ranked table makes them look. Amazon ALB carries 69,748 domains (22.81%), Google Cloud Load Balancing 50,798 (16.61%) and Azure Front Door 48,175 (15.75%), 55.17% of the category between them. Google Cloud Load Balancing and Azure Front Door are 0.86 points apart, the closest pair in the table, and Amazon ALB carries 1.45 times Azure Front Door's footprint. Below those four the category empties out fast: the eight technologies ranked fifth to twelfth hold 25,813 domains between them, just over half of Azure Front Door's own count. We track how the same providers carry global traffic in our cloud provider traffic share report.

A barbell, not a curve

Two distributions on this page point in opposite directions and both are right. On size, 36.95% of the 22,558 companies that report a headcount employ ten people or fewer and 60.18% employ 50 or fewer. Nothing unusual in that tail; every infrastructure list has one.

Then look at the other end. 2,395 companies, 10.62%, employ more than 1,000, and 566 of them employ more than 10,000. The same band is 7.49% on our Microsoft Azure platform profile and 2.56% on AWS. An enterprise weighting heavier than the platform it belongs to is a strange thing for a component of that platform to do, unless it is being sold and bought separately, which is what the co-occurrence number already told us.

Age says it louder. The 2010s lead at 23.78%, as they do almost everywhere, but the second-largest bucket is Pre-1960 at 18.09% and 49.38% of the companies with a founding year predate 2000. The State of California is recorded at 1850, Tata Sons at 1868, Chevron at 1879, Bosch at 1886, Philips at 1891 and Becton Dickinson at 1897. Organisations of that age rarely rebuild their hosting. They put something in front of it.

Read the detection URLs, not the company names

18 of the 34 organisations named on this page were detected on a hostname other than their main site: cookienotice.deloitte.com, myprivacypreferences.abbott.com, mypreferences.aon.com, rx.costco.com, partners.subway.com, orderweb-cdn.chipotle.com, prd-sc102-cdn.rtx.com, framework-assets.external.xerox.com, fs.qatarairways.com, my.bd.com, myhazards.caloes.ca.gov.

Read that as a job description. Consent and privacy portals, partner and ordering systems, asset hosts, customer logins, a state government service. These are the properties where latency and availability are one team's specific problem and the main marketing site is someone else's. A global edge gets bought for one of them and spreads from there, which is why a detection here is usually a workload rather than a company-wide decision. Microsoft's own azure.microsoft.com is in the list too, which earns a line for what it is: the product serving the product's marketing site.

Why there is no migration table here

Switching between these products has not been measured for this profile, so the section is empty. I would rather leave it empty than infer a migration from a churn count, which is the most common way a number of this kind goes wrong: domains leave a technology for reasons that have nothing to do with any competitor.

What is measured is turnover, and it is remarkably low. 1,895 domains have stopped answering from Azure Front Door since mid-March 2026, 953 of them inside the last 30 days. Against the 48,175 domains on this page that is a 3.9% drop rate, among the lowest on any profile we publish. Two things are mixed into that and they are worth separating before anyone reads it as loyalty. Part is the product: an edge is disruptive to move and rarely moved casually. Part is the marker: a signal carried in a response header stays put, where one read from a page's markup disappears every time the page is rebuilt.

A 3.9% drop rate is the easiest number on this page to misread. Some of it is a stable product. Some of it is just a stable signal.

What to take from this

Azure Front Door is a bought edge whose buyers do not look like the platform it comes from. It ranks 4th of the 12 technologies in Load Balancers & Proxies on 15.75% share, less than a point behind Google Cloud Load Balancing. The base is American first, 40.6% of located companies, and English-speaking second, 62.64% across four countries, with Denmark, Sweden and Norway each placing above Spain, India and Italy. The industries are retail, financial services, health care and government rather than the software companies that lead the platform list.

If you sell anything that sits in the request path, the segment to separate is the 10.62% employing more than 1,000. They are already paying for an edge, they mostly run something other than Microsoft behind it, and their detections sit on the portals and ordering systems where a second opinion about latency is already somebody's job. Cloudflare is on 18.99% of these domains, so a second slot is frequently taken as well. TechnologyChecker.io resolves the 48,175 detections against 24,109 identified organisations and refreshes them every month.
