Threema – The secure messenger for individuals and companies

Threema Work
The Secure Business Messenger

Don’t compromise on security. Protect your business chats and the privacy of your employees and business partners.

Threema
A Decade of Seriously Secure Messaging

Ten years ago, on 12/12/2012, the first ever Threema version was published in Apple’s App Store.

Your Private Life Is Valuable
Don’t Pay With Your Data

There is no such thing as a free lunch. If you don’t pay money for a messenger service, you pay with your data instead.

Ice Cream in Exchange for Your Data

How old are you? What’s your phone number? … We used a candid camera to test how much personal information is shared for a free ice cream. The result is entertaining.

Never be lulled into a false sense of security. Only a truly secure communication channel protects information from falling into the wrong hands.

Secure Communication for Individuals with Threema

Pay once, chat forever. No collection of user data. Open Source.

Thanks to consistent 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.

Secure Communication for Companies
with Threema Work

Trusted by millions. Reviewed by security experts. 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. The chat application 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 the company messenger Threema Work, employees communicate within the team 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. This is where the business messenger Threema Work comes in.
