Contentful has introduced "embargoed assets" to its platform, a feature that allows customers to restrict access to cached assets on the global CDN infrastructure, using an authentication mechanism that only returns assets to visitors signing their requests with valid signatures. This new feature enables customers to control who has access to content authored through Contentful, and can be used for various use cases such as intranets and extranets, paywalls and gated content, campaigns and product launches. The feature is now available on the Contentful Premium tier and can be activated on a per-space basis. To implement embargoed assets, customers need to integrate the URL-signing solution into their authorization workflow, but Contentful has provided a tutorial and FAQ section to help with this process. The solution adds 20-40 milliseconds of latency to requests, which is imperceptible to end users.
