ISL Online: sovereignty score and 8 European alternatives

ISL Online is a remote desktop and remote support platform; its main client is ISL Light. Support staff can help customers in attended sessions or use a remote access agent for unattended access, and administrators manage users and groups. Deployment is either self-hosted, with a server licence in the customer's own environment, or a Managed Private Cloud, described as a single-tenant system. According to ISL Online, data between operator and client is end-to-end encrypted with AES 256-bit.

The software is provided by ISL Remote d.o.o., a company organised under Slovenian law with its address in Ljubljana. In 2025 ISL Online was acquired by PDQ, whose headquarters are in Utah, USA, so a US parent now owns the vendor, which is a relevant CLOUD Act signal. The pages consulted do not state the countries where the cloud servers are located. With a self-hosted server licence, the organisation decides where the data resides.

Why digital sovereignty matters with ISL Online

ISL Online is headquartered in SI and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

ISL Online 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.

ISL Online 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 ISL Online together with your other vendors and gives a total score, a heatmap and the main risk drivers.
