MediaSilo: sovereignty score and 8 European alternatives

MediaSilo is a cloud platform for media asset management and review from EditShare, aimed at production and post-production teams. It supports timecoded feedback, version management, dailies, approval workflows and protected external review through a browser link, with watermarking, expiring links and audit trails. An AI search function covers transcripts and footage. The platform is offered as a subscription service and the software is proprietary.

EditShare, the company behind MediaSilo, is headquartered in Watertown, Massachusetts, in the United States, with another office in the United Kingdom. According to its developer documentation, MediaSilo is built on Amazon's cloud infrastructure and stores media on Amazon S3 by default; customers can also connect their own S3 account. The documentation does not say which AWS regions are used. Because the vendor is US-based, US law such as the CLOUD Act may apply to the data. A European organisation should have the storage location of its media confirmed in writing before adopting the service.

Why digital sovereignty matters with MediaSilo

MediaSilo is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

MediaSilo hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

MediaSilo is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs MediaSilo together with your other vendors and gives a total score, a heatmap and the main risk drivers.
