What is SekurMessenger?

Encrypted messaging application designed for organizations that need to protect their flow of information and secure their communications between devices, with customers and partners.

SekurMessenger is not just any ordinary messaging app. It is designed to provide military-grade encryption and privacy by design ensuring that only the sender and intended recipient can read the messages exchanged.

It also employs multi-vault encryption layers, segregating users' data in virtual vaults and encrypting it with individual keys. This means that your data is safe even if one layer of encryption is compromised.

We do not collect or store metadata of any kind, or share information with third parties, and guarantees privacy using its own servers.

SekurMessenger works for both licensed users of the application and external users who do not have the APP.

Hosted in Switzerland SekurMessenger is protected by some of the world's strongest privacy laws and remains outside of US and EU jurisdiction.

We can't read your messages or listen to your calls, and no one else can either.

We are free form ads, third party espionage or any tracking because we are not connected with any big tech company.

True privacy is not needing your phone number to communicate, your profile is not associated with personal data.

Protecting sensitive information, maintaining privacy, and preventing cyber attacks is our core.

SekurMessenger provides fully private instant chats with no hidden storage or data mining. This means that your conversations are kept completely private and cannot be accessed by anyone else. SekurMessenger uses end-to-end encryption to ensure that your messages are secure and cannot be intercepted by anyone else.

One of the key features of SekurMessenger is that it is built on proprietary code without open source involved. This means that the code used to build SekurMessenger is not publicly available and cannot be modified by anyone else. This ensures that the service is secure and cannot be compromised by anyone.


Data is transferred from device to secure servers in an encrypted tunnel.

Our proprietary technology HeliX® wraps data transfer in 2048-bit encryption with multiple layers of proprietary encryption intertwined in HeliX® form on top of it, which creates multiple layers of encryption many times stronger than others.

With our own servers in Switzerland Sekur is 100% cloud-based privacy granted.
