Intego Updates ChatBarrier X4 iChat Encryption Software Providing Secure
Text Chats, Audio Conferences, and File Transfers

Austin, Texas, June 9, 2006 — Intego, the Macintosh security specialist,
today announced the launch of ChatBarrier X4, a new version of its
acclaimed program that works in conjunction with Apple’s iChat instant
messaging software to provide two-way, real-time encryption of text chats,
audio chats and file transfers. ChatBarrier X4 uses industry standard
encryption that prevents hackers or unintended recipients from reading
private messages.

ChatBarrier X4’s real-time encryption protects text messages, audio
conversations or files sent during a chat session with iChat, which travel
over unprotected servers around the world. Because ChatBarrier X4 provides
real-time encryption, as soon as a user presses Return to send their
message, it is encrypted, guaranteeing that nobody but the intended
recipient can read it. In addition, even if messages are intercepted,
ChatBarrier X4 ensures that they are unbreakable. Messages are sent in
milliseconds and the recipient’s copy of ChatBarrier X4 decrypts them just
as quickly.

“Instant messaging is a powerful tool for businesses, and its immediacy can
make it much more practical and efficient than e-mail”, said Laurent
Marteau, CEO, Intego. “But many businesses hesitate to allow the use of IM
software and rightly so. It’s simple for hackers to record messages sent to
and from company networks, or to intercept files transferred via iChat. The
only way companies using iChat can ensure their messages are kept secret is
to use ChatBarrier X4, which provides unbreakable encryption in both
