A court in India has ordered the encrypted email service Proton Mail blocked in the country for refusing to share information with authorities.

In an April 29 hearing of the High Court of Karnataka, Justice M Nagaprasanna ordered the government to “block forthwith” domain names associated with Proton Mail, citing authority under the country’s Information Technology Act of 2008. The order stemmed from a complaint filed in January by a New Delhi-based design firm, alleging that some of its employees received offensive emails through the service.  

It’s unclear whether the ban will take effect or face other possible challenges in court. The Proton team reported in March 2024 that Indian authorities had similarly proposed ordering the service blocked in response to alleged “hoax bomb threats,” but it continued to operate in the country.

The crackdown on Proton Mail appeared to be part of a larger global trend to pursue action against platforms based on users’ activities, such as the arrest of Telegram founder Pavel Durov in France in part for allegedly failing to moderate illicit content. Cointelegraph reached out to Proton for comment but did not receive any response at the time of publication.

In Spain, Proton AG — the Swiss company behind the platform — provided information to the authorities about one of its users in 2024. The move had many privacy advocates questioning the security of their data with the centralized service.

Cryptocurrency exchanges are no stranger to legally sanctioned crackdowns attempting to curtail their activities in a country, or in some cases, face blocks or bans. US authorities imposed sanctions on crypto mixing services like Tornado Cash in 2022, facing swift backlash from the industry and legal challenges, while South Korea reportedly blocked 14 exchanges on the Apple store for allegedly operating without the proper registration.

In India, users face a 30% tax on profits from crypto trading, which has been in effect since April 2022. Though crypto firms operating in the country endure increasing regulatory oversight, India is estimated to have more than 100 million digital asset holders out of its roughly 1.4 billion people.
