Top 10 European Privacy Technology Companies

Europe is the global capital of privacy technology, home to the world's strongest data protection framework in the GDPR and a growing ecosystem of companies building infrastructure for a privacy-first internet.

In 2025, GDPR enforcement fines exceeded €4B for the first time, supercharging demand for compliant privacy tooling.

Tresorit

Tresorit's client-side encryption means even Tresorit cannot access user data, making it the compliance solution of choice for European law firms, healthcare providers and financial institutions under GDPR.
