[H2] Personal Communication with Consistent Privacy Protection

To Threema Private

[H2] Why You Can Trust Threema

In times of data leaks and growing cyber threats, trustworthy communication is crucial. Conventional messengers often compromise your data and compliance requirements. Threema offers a secure alternative without compromise.

[H3] Consistent End-to-End Encryption

All messages, calls, and files are protected with strong cryptography based on open-source encryption technology. Perfect Forward Secrecy prevents retrospective decryption even in the event of key compromise – for reliable protection of confidential communication.

[IMG: Two laptops with chat and Threema icon – symbolized end-to-end encryption.]

[H3] Zero-Knowledge Principle for True Confidentiality

Thanks to the zero-knowledge architecture, only the intended recipients can read your messages – neither third parties nor Threema itself have access to the content. Your communication remains exactly where it belongs: between you and your chat partner.

[IMG: Threema chats with metadata disposal icon – symbolizing data protection.]

[H3] Anonymity Without Personal Data

Unlike most other messengers, Threema does not require a phone number or email address. Your unique Threema ID enables confidential communication without revealing your identity or personal network.

[IMG: Video call with chat bubbles No ads, no data collection.]

[H3] Minimal Metadata, Comprehensive Privacy

Threema reduces metadata to the technical minimum. Messages disappear from our servers after delivery, and contact lists remain on your device. This way, you leave hardly any digital traces and effectively protect your digital identity.

[IMG: Threema chats with metadata disposal icon – symbolizing data protection.]

[H3] Swiss Quality and Trustworthiness

As a Swiss company, we develop exclusively in our own country and operate redundant server infrastructure in Switzerland. Benefit from strong Swiss data protection standards and robust operational security.

[IMG: Laptop with mountains, Swiss flag and emojis – symbolized Swiss origin.]

[H3] Seamless GDPR Compliance

Threema meets all data protection requirements and goes significantly beyond minimum standards. For companies, this means documented legal certainty and protection against costly compliance violations in digital communication.

[IMG: Smartphone with ISO27001, GDPR, and Swiss DPA badges on chat screen.]

[H3] Verifiable Security Through Open Source

Trust through transparency: Our open source code and regular external security audits demonstrate our high standards. With reproducible builds, you can verify the integrity of the installed apps yourself.

[IMG: Laptop showing Threema source code – symbolized open source.]

[H3] Independent from Ad Networks and Big Tech

Threema does not sell user data but is built on a clear business model. No advertising, no tracking, no profiling – just reliable, uninterrupted communication. Your digital exchange remains private – today and in the future.

[IMG: Video call with chat bubbles No ads, no data collection.]

[H2] The Dangers of Cyberattacks

Top executives and security experts rate cybercrime as the greatest current threat to companies worldwide. The threat landscape has intensified in 2024 and 2025, with new, sophisticated attack methods and increasing financial damages.

In the second half of 2024, over 1,000 cyberattacks per week per company were recorded – a 30% increase compared to the previous year (Source: Check Point Research). Particularly at risk: the communications industry and critical infrastructures.

[H3] Around 10 Trillion Euros in Damage Worldwide

Each data breach costs companies an average of USD 4.9 million today (Source: IBM). The global total damage could reach the 10-trillion mark by 2025.

[H3] GDPR Violations Endanger 4% of Your Revenue

In 2023 and 2024 alone, the EU imposed over 4.5 billion euros in fines – including 1.3 billion euros for Meta (Source: Reuters). Companies risk up to 4% of their global revenue for violations.

[H1] Threema Work as official company messenger

Mercedes-Benz Group AG (formerly Daimler AG) is one of the world’s largest manufacturers of cars and commercial vehicles, its most famous brand being Mercedes-Benz. The long-standing company also offers financing, leasing, fleet management, insurance, and innovative mobility services.

[H3] Use Cases

Threema Work is the official instant messenger for the entire company. It’s prohibited to use conventional chat apps for business purposes on company phones.

Primary use case is the exchange of ad-hoc messages and team communication in group chats.

Threema Work is also used for broad information distribution and top-down communication, e.g., by Leadership 2020.

Notification systems also increasingly incorporate Threema technology by using Threema Gateway.

Threema Work is available to all employees – on both company phones and BYOD devices..

Modern on-the-go communication in business environments is subject to the same security requirements as traditional communication. Threema Work combines speed and usability with these requirements!

Instant messaging has become an indispensable part of everyday life; it’s of utmost importance that internal business information stays inside the company.

Strong end-to-end encryption, effective privacy protection, and high availability are key when it comes to messaging services.

Threema Work is the ideal complement to other collaboration tools that focus on desktop messaging and video conferencing.
