Intruder: sovereignty score and 8 European alternatives

Intruder provides a web-based security platform that runs vulnerability scans, monitors the attack surface, performs cloud security checks and offers AI-assisted penetration testing. It is delivered as software-as-a-service, with customers logging in to a web portal to set up scans and review findings.

Intruder is a trading name of Intruder Systems Ltd, a company registered in England, so it is a UK business outside the EU and EEA. Its privacy policy states that its services are hosted on Google Cloud Platform in the London region, and that some third-party processors may be located outside the EU and EEA. The policy does not mention the GDPR or a data processing agreement. European organisations should request those terms directly and note that the data is hosted in the UK.

Why digital sovereignty matters with Intruder

Intruder is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Intruder hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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