Menlo Security: sovereignty score and 8 European alternatives

Menlo Security is a cybersecurity company offering cloud-delivered remote browser isolation and a secure enterprise browser, under its Menlo Browser Security Platform. Risky web content is rendered in the Menlo Cloud, and according to the vendor only safe, sanitised content reaches the user's device. The vendor describes a hybrid model that combines local security controls with cloud-based protection, aimed at organisations that want to limit browser-based threats.

Menlo Security is based in Mountain View, California, and was founded in 2012; the vendor names no owner or parent company. The vendor refers to the Menlo Cloud but does not name data-centre regions. For a European organisation, all browsing traffic routed through the service is processed by a US-headquartered provider, so hosting regions, sub-processors and a data processing agreement should be confirmed before deployment. The product is proprietary and not open source.

Why digital sovereignty matters with Menlo Security

Menlo Security 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.

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

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