As cyber threats increase and data protection requirements grow stricter, businesses and public authorities face a clear challenge: how can confidential information be communicated securely, quickly, and efficiently—without relying on insecure tools? The answer lies in specialized business messengers with end-to-end encryption that meet compliance requirements while supporting everyday digital workflows.
stashcat by secunet is designed precisely for this use case—a solution that combines modern messenger functionality with the highest security standards.
The challenge: Fast and secure communication for businesses and public authorities
Messengers like WhatsApp or Signal play a central role in communication. Many people use them as replacements for SMS and email due to their speed, simplicity, and informality. As a result, they have spread into business environments, often improperly, as part of so-called shadow IT.
This is why businesses and public sector organizations increasingly need to provide their employees with business messengers for secure, real-time communication. The ability to communicate across organizational boundaries and the protection of critical infrastructure place additional demands on the tools being used. Ideally, these tools should also be intuitive and offer a practical alternative to existing apps.
To prevent data loss and industrial espionage and to meet all data security and protection requirements, organizations need encrypted business messengers designed for trustworthy communication. However, complex IT infrastructures, limited interoperability and a lack of standardization make it difficult to introduce secure alternatives. Compliance concerns and a general lack of trust in the offerings of major internet companies further complicate the situation.

- Shadow IT caused by the use of insecure messengers in the workplace
- Strict requirements for data protection, encryption and compliance
- Complex IT environments and lack of interoperability
