Secure Communication for Individuals with Threema
Pay once, chat forever. No collection of user data. Open Source.
Thanks to state-of-the-art end-to-end encryption, no one other than the intended recipient can read transmitted messages, not even Threema as the service operator. It’s not required to provide any personal data whatsoever: If so desired, Threema can be used completely anonymously, i.e., without disclosing one’s phone number or email address. Threema was built from the ground up with data protection and privacy in mind (Privacy by Design), which is why only as little metadata as possible is generated when using the service.
Threema is 100% Swiss Made, hosts its own servers in Switzerland*, and, unlike US services (which are subject to the CLOUD Act, for example), it is fully GDPR-compliant.Learn more
No phone number required
Secure Communication for Companies
with Threema Work
Trusted by millions. GDPR-compliant. Built for business.
Instant messaging has become a crucial part of everyday business life some time ago, and it has replaced email in many instances. Threema Work enables companies to make use of instant messaging for corporate communication without taking any risks.
Every company benefits from a secure and privacy-compliant WhatsApp alternative. With Threema Work, employees communicate in a fast, efficient, and straightforward manner – without the danger of business secrets or user data getting into the wrong hands. Also, there’s no more reason for the staff to adopt a dangerous shadow IT.
Collaboration solutions such as MS Teams pose considerable legal risks for companies due to their lack of effective end-to-end encryption and metadata protection. Therefore, such tools cannot be considered a substitute for a secure instant messenger.
