We implemented most recent achievements and cutting-edge technologies in information technology security to develop cryptographic protection mechanisms for our instant messenger. The level of encryption and its performance meets the most stringent banking standards.

Your private or business information is totally safe and confidential when using our chat messenger. SafeUM eliminates any possibility of data interception and spoofing and also provides the parties' authentication. Here's more information on the technology, cryptographic systems, functionality and features:

>> P2P mode of voice and video calls involves direct data transfer between users bypassing our servers. The communication channel is not limited to the server capacity which distinguishes SafeUM from all other popular instant messengers.

>> Encryption. The information is encrypted by subscriber A, stored on the server and transmitted in encrypted form. After going through communication channels it is decrypted by subscriber B. The information is open only at the end nodes - where it is encrypted – users' mobile phones or tablets. Any other equipment such as servers, switches, routers  and SafeUM servers contain encrypted information. 

>> Digital signature is another reliable way of data protection during transfer. This automatic technology authenticates the parties and ensures data integrity. Account and chat hacking  as well as spoofing are totally eliminated.

>> Hybrid encryption scheme. A symmetric block encryption algorithm is used to increase the encryption performance. Asymmetric elliptic curve cryptography is used to transfer the encryption key in the data exchange process.  It has high levels of cryptographic security with a relatively small key length. This hybrid scheme allows to "take the best" out of each system and combine into one cryptosystem with very good encryption performance and cryptographic security as well.

>> The ElGamal scheme is used for symmetric key transport. SafeUM cryptography experts implemented complex algorithmic optimization of the encryption process taking into account the stringent requirements of the banking sector. The application works fast and ensures high quality communication without any delays. In other words - the communication quality is equal to that of the other chat messengers but at the same time it provides a very high level of information security and extremely fast encryption performance.

>> Our servers have no hard drives. We use Redis in-memory database - the best option for SafeUM that allows to store all (!) the data in RAM. Third parties can only access these data after going through a complicated legal and bureaucratic procedure. And even then SafeUM can disclose only the encrypted data. We do not have private keys. They are generated on the basis of the pass-phrase that the user must remember. We, being the providers, cannot decrypt messages stored on the server. >> SafeUM multimedia messenger comes with an exclusive set of functionality. You can simultaneously use up to three accounts online in one messenger. No phone number is needed to sign up. What do you think about the disable chat history saving feature? How about the screen shot protection during the dialogue? And voice modification feature? SafeUM uses a system of three security PIN codes: first is used to sign in, second - to access secret contacts and chats and the third one - to deactivate the account in case of any information security threats.

You can choose your level of security, choose your subscription and free yourself from any communication security concerns.

You may ask why you have to pay for some tariff plans? Our messenger is a commercial product. We do not want and will not deceive you and sell your personal information to marketing specialists. We have invested in our product development without attracting any potential customers' donations or engaging any sponsors. Every cent invested was spent on quality, design and exclusive functionality.

We do not set out terms, we offer you to decide what communication security level to select. Only you decide what kind of information you want to disclose. We do not track your phone, it is of no interest to us. Our priority is to create a unique and most secure communication environment!

We offer you to choose from a set of completely unique features to ensure the security of your personal and business communication.
Our customer support team will answer any questions you may have.

We do not ask you to take our word! You can check the reliability of SafeUM secure messenger if you wish. At the same time our development team is moving on and we will improve and expand our product features in future releases.
