Check Point is introducing an upgrade to its Integrity line of software that secures computers connected to corporate networks over SSL VPN links.
Called Integrity Clientless Security 3, the new version introduces what the company calls a quarantine browser named Integrity Secure Browser that uses encryption and cache-cleaning to keep remote access sessions confidential.
The quarantine browser is an Active X agent that snags temporary files and caches that would normally be kept during remote sessions. It prevents them from being stored in the usual temporary files and encrypts them within the cache it creates. When the session is over, it wipes out the cache so no trace is left.
Cache cleaning is technology that other SSL VPN vendors that don't use Check Point technologies, also include with their products as a way to wipe out traces of SSL sessions that might otherwise be stored in browser caches and temporary Internet files, as well as caches that are specific to individual applications. These cache cleaners have varying levels of thoroughness and sophistication.
Integrity Clientless Security 3 also adds automatic updates for Check Point's spyware signature files, as well as updates to Integrity itself. Integrity software that sits on SSL VPN servers can be configured to periodically connect with a Check Point server to download these updates.
The latest release adds support for Mozilla, Netscape and Opera browsers. Before, it supported only Microsoft's Internet Explorer.
In addition to protecting SSL VPN sessions, the software can be installed on mail servers and Web servers to protect sessions that connect directly to them.
The new version costs US$20 per user, less if a customer buys in bulk.
