The most secure file transfer approach – The first best step to increase your security. Protect the files so securely that it takes away the most vulnerable weak link of data-in- transit.



Safety4Transfer is a comprehensive, user-friendly tool for the exchange of encrypted data between two and more users. The application has been developed on the basis of long-term experience in the field of secure data transmission and is based on the application Safety4Data, which the subsidiary company IT-CNS, Inc. has been selling successfully on the North American market since 2014.

European experience in healthcare, the financial sector and the automobile industry, along with experience in cooperation with American law and tax firms, marketing agencies and IT firms working on the East Coast of the USA, has convinced us that there is room on the market for a user-friendly secure tool for the simple exchange of encrypted data, be it between two subjects or within the context of a defined group of more subjects. Safety4Transfer (S4T) does not aim to compete with email or a public or private cloud solution, but to complement it suitably and significantly increase the security of transmitted data. On the basis of previous experience and the requirements of users, the tool Safety4Data was created for the North American market, and Safety4Transfer was created for the European market. In the new generation, both applications use the latest possibilities for securing and encrypting data, for saving and for actual transmissions.

The advantage of S4T is that S4T encrypts and secures each sent file separately, and it does so locally, directly on the user's computer. So the files that the user sends using S4T leave the local computer already fully protected, and neither the service provider nor anyone else on the transmission route or in the cloud storage has access to the data, nor are they capable of opening and viewing files.

Enterprise-grade security is created using a combination of two proven technologies: HTTPS (including the PFS algorithm) and Public Key Infrastructure (PKI). Data security is created by using the Windows Azure server environment – technology which delivers a superior level of confidentiality, integrity, and stored data availability. Data is transferred through the highly secure HTTPS (SSL 3.0 / TLS 1.2). The server is then authenticated by a server certificate, verifying that the user is communicating with the legitimate Safety4Data application, not a spoofed server. Security is further enhanced by the optional use of Public Key Infrastructure (PKI). When using PKI, the user can secure not only the server authentication, but also the Safety4Data user authentication. In addition, users can encrypt/decrypt files using PKI. During transfer, data is sent via Safety4Data’s highly secure, encrypted HTTPS tunnel. Files are encrypted and stored on Safety4Data servers until the recipient downloads them, at which time the files on the server is permanently deleted. Encryption certificates are acquired via "Certificate Authorities" and managed by the company to optimize security.

Safety4Data is an easy-to-use, peer-to-peer data transfer application. Once user accounts are set up, transferring files is as simple as dropping them into a folder. High-speed data processing is then ensured by using Windows Azure servers. Our easy-to-use application has been developed with non-technical users in mind. Safety4Data uses this philosophy in every step of the installation and setup process too, meaning everybody – not just IT professionals – now have access to enterprise-grade encryption technology. As a result, Safety4Data not only secures your data, but can also save your business time and money.

The speed of the Safety4Data application is supported by the robust Microsoft Azure network. Both the HTTPS protocol and Public Key Infrastructure (PKI) are used for data transmission. High-speed data processing is ensured by placing Safety4Data servers on the Windows Azure network. The application's user interface has been developed for non-IT professionals. Combining Azure with ease-of-use optimizes how quickly users can set up the application, create new users, and transfer files to their peers.

The administrator of your Safety4Data account can fully customize the communication path settings and individual user authorizations. Authorized personnel can create a private, secure communication network by using the common rules and protocols. This setup is managed in an easy-to-use administration panel that requires no IT or technical know-how. As a result, anyone can create a secure and efficient data transfer network for sharing private and encrypted data.

Safety4Data is a set of CNS-developed software and tools (the "Service") used to provide a hosted application built on client-server architecture to enable, at the Subscriber's option, the creation of virtual secured networks utilizing HTTPS protocol security and public key infrastructure for the purpose of sending and receiving messages that are encrypted in transmission according to users’ rules. The server-side component of the Service (the “Server-Side Component”) is hosted by CNS in CNS’s Microsoft Azure cloud environment and includes CNS’s proprietary web application (the “Web Application”). The Subscriber’s Administrator(s) use the Web Application to (a) create, edit, delete and manage accounts for new and existing Authorized Users, (b) review usage statistics regarding data and files exchanged through the Service, and (c) access the payment module. The Server-Side Component also provides access to configuration settings and, for a limited time, will host users’ files while in transit through the system. The Web Application is optimized for Internet Explorer, Mozilla Firefox and Google Chrome, with the supported versions and operating systems as set forth in CNS's then-current documentation. The client side is a standard 32/64 bit application (the “Client Application”). Under the execution of this agreement, the Client Application has been successfully tested for OS Windows 7/8 and Windows Server 2008/2012. Subscriber’s Authorized Users can use the Client Application to upload and download data automatically, designate whether such data will be sent in encrypted form and enables recipients of data sent through the Service in encrypted form to decrypt such data. The client application is installed to Safety4Data users’ hardware (pc/server).
