Real-time messaging for real-time business™

Welcome to!

VyPRESS Research is a developer of instant messaging and alerting software for local area networks and business intranets. We have been developing software for this market since 1997 and take great pride in our achievements and rapid growth.

Vypress Chat

Vypress Chat is designed for office and home networks.

After several years of experience working in the intranet instant messaging market, we discovered that many office and home networks operate without centralized administration. We made Vypress Chat especially for these networks. It is fully self-configurable, works with TCP/IP network protocol and doesn’t depend on a dedicated server.

Vypress Chat requires no post-setup steps to operate and immediately offers an online user list (list of people who have Vypress Chat running in your office network) as well as their availability status (“I’m busy”, “Out of office”, “On the call”, etc).

All conversations can be logged into a XML file and easily integrated into the business workflow.

With Vypress Chat no data can be sent outside of your office network, so, it is completely confidential.

Vypress Chat is a flexible, integrated solution expressly designed for fast, trouble-free installation and operation.

Chat Terminal

Chat Terminal is free chat software for local area networks that is compatible with the Vypress Chat. It works on Windows, Linux, and Mac OS X platforms.

This command line tool without rich user interface may be very useful for local area network administrators, developers who make the Vypress Chat compatible software, or for experienced users who is interested in more complicated usages of chat software.

Chat Terminal is Open Source project so anyone can modify it according his requirements.


SafeKuvert is a computer application that provides the user with the ability to encrypt, digitally sign, compress, and/or securely delete files from the hard disk.

The encrypted files can be decrypted only on the computer where the private key of a certificate of encryption was saved, but a private key of a recipient's certificate is not required in order to create an encoded file. Thedigital signatures can be verified on any computer where SafeKuvert is installed. The files can also be compressed before encoding is applied. Algorithms of asymmetrical encryption (RSA) ensure that data cannot be accessed even if the hardware in which an encoded file was stored is lost, or if the file is transferred through public, unsecured computer networks. The application actively uses the Public Key Infrastructure (PKI), which is built into Windows, as well as the standard X-509 certificates and the Windows Shell extensions, which makes using the program very easy and convenient.

Vypress Messenger

Vypress Messenger is a program for sending text messages with attachments in real-time, without using any additional servers, from one computer to another or a few others.

The program supports several messages transferring protocols, including its own protocol, for guaranteed distribution of direct messages, using a TCP protocol and a multiple-address file distribution, using UDP and IP Multicast. Besides this, the program supports a standard SMB protocol (for compatibility with WinPopup, ‘net send’ and Unix-realizations of Samba).

The main benefit of the program is its fault-tolerance and independency from the network infrastructure. Vypress Messenger has been originally developed and specially optimized for LAN. It doesn’t use staging servers, and that way the user can send and receive a message even if all of the company’s servers are out of service due to some breakdown or an external attack.

For special circumstances, the program provides the ability of sending high-priority messages and creating macros for sending out preset messages with a single mouse click.

Vypress Auvis

Vypress Auvis offers “receive only” messaging capabilities.

Vypress Auvis brings you focused solution to your one-way messaging, emergency notification, popup alerting and critical broadcasting needs.

Users can receive messages from a variety of sources, including Vypress Messenger, WinPopup, OS/2 Messenger and any other SMB-compatible messaging service. The primary purpose of Vypress Auvis is to offer network administrators the ability to control all aspects of the end-user interface. The administrator can hide all settings, disable closing of the program, define allowable message sources and more.

Auvis is an incredibly easy-to-use, lightweight application that operates on only 450 KB of RAM. Designed for use in large to very large corporate networks, Vypress Auvis offers fast deployment features and keeps the total cost of ownership at the lowest possible level.


WinMessenger is an easy to use program that allows you to send and receive messages from computer to computer in real-time without using dedicated servers.

It works over any network protocol, it is easy to deploy and it does not require computer knowledge or special configuration. Simply put, it is standard WinPopup without the blemishes. WinMessenger offers complete implementation of the SMB protocol, so with it you can do everything you can with WinPopup. For example, you can send a message to a Novell user, receive messages from Linux systems, send and receive messages to/from Windows NT servers and so on.

WinMessenger works exceptionally well under all existing implementations of Windows without any updates or upgrades required — from the original release of Windows 95 to the latest Windows XP/2003.

The program can be used on Windows 2000 Server or Server 2003 with Terminal Service enabled.

We offers lan instant messenger and WinPopup / 'net send' replacements
