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 while complying with laws and regulations such as the GDPR and NIS2.
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.
