Download websites that use Contensis

The interesting column on this record is not the site count, it is the version spread. Across the 199 sites where we detect Contensis as of October 2026 there are 16 distinct versions in circulation, and 16.2 carries the bulk of them. A platform whose install base fans out across that many releases is not being upgraded centrally by its supplier. Each customer decides when to move, which is what happens when software is licensed and run rather than rented.

The pattern has consequences for anyone building against the platform. An integration cannot assume the current API surface, a security question cannot be answered for the population as a whole, and a support matrix has to cover releases the vendor itself may already have retired. The spread also tells you the detected population is made of long-lived deployments, sites that were built once, are maintained by whoever won the contract, and get replatformed on a rhythm measured in years rather than quarters.

The rest of the record fits a considered-purchase product. Contensis is a Proprietary platform from Zengenti, and our earliest year on record for it is 2000, which puts its origin in the first commercial generation of web content management rather than in the recent headless wave. Products of that vintage that are still shipping releases have usually managed it by holding a defensible niche, typically a sector with formal procurement, accessibility obligations, complicated site estates and a long tolerance for the same supplier.

A few hundred detected domains should be read in that light. In a mass-market content platform category the number would suggest a product that never found users. For a platform sold through tender to organisations that run many sites at once under a single contract, the same number can represent a healthy book of business, and each detected domain is a lead with a budget behind it rather than a hobby site.

Checking one domain tells you which content platform a single organisation chose. The full list tells you the set of organisations that chose it, and with the version attached, which of them are running releases that are behind. The two facts together are the working material for competitive displacement, for agency and partner recruitment, for security research aimed at outdated deployments, and for anyone selling search, accessibility, translation or analytics into an established base.

Two limits are worth stating. Version strings come from public artefacts and can be suppressed, so the spread we report is drawn from the deployments that disclose rather than from all of them. Our record also carries no country or TLD field, so geography has to be read from the domains in the export rather than assumed from the supplier's home market.
