All our testing was done against SecureLogix's ETM version 3.03. But we had the opportunity to play with pending version 4.0, which should be shipping in mid-November, for one day at the end of our testing.

ETM 4.0's best gee-whiz feature is TeleVPN Call Shield 1.0, a policy-based telecom VPN (PRI only, T1 support pending) proving 3DES (Triple Data Encryption Standard) encryption services to any phone, fax or modem. This lets any two sites with the right ETM equipment encrypt (in real time, thanks to some DSP [digital signal processor] magic) all transmissions between locations. Pretty neat stuff. Also of note is the new AAA for TeleWall Firewall 1.0, an authentication, authorization and accounting services application to assist in maintaining a distributed telecom environment.

ETM 4.0 also addresses faster modem declaration--a much better 1-to-2-second time instead of the current version's 25-to-30-second requirement to identify and apply rules to a detected modem transmission. Finally, version 4.0 delivers a 2.4.19 Linux kernel upgrade and provides a number of interface and performance improvements that users will appreciate.

All current customers under service contract will receive the upgrade free of charge.
