Proventia M30 Brings Easy to Use, Cost-Effective Security to Organizations of All Sizes

ATLANTA, March 29, 2004 - Internet Security Systems, Inc. (ISS) (Nasdaq: ISSX) today announced the expansion of its ProventiaT integrated security appliance line with the Proventia M30, a new security product designed for the mid-market.

For the past decade, ISS has been the trusted security advisor to Global 500 companies and world governments. Now ISS is bringing its advanced protection to mid-size organizations at an affordable price of $3,495 for the Proventia M30. The appliance combines intrusion prevention and detection, firewall, VPN, anti-virus, Web filtering and anti-spam for complete protection in a single box.

"The same security Global 500 companies and world governments have relied on for years is now available to mid-size organizations with the Proventia M30," said Greg Adams, vice president of product management for ISS. "Previously, this level of security was unavailable or unachievable for smaller businesses because of the cost and the complexity of standalone solutions."

Proventia integrated security appliances stop Internet threats before impact, preserving network uptime, improving productivity and preventing embarrassing security breaches. With its combined functionality, the Proventia M30 automatically blocks viruses, worms, hackers and major Internet attacks like SQL Slammer, Code Red and MS Blaster. Proventia also receives updated protection for new software vulnerabilities to keep businesses ahead of the next threat.

Integrated security appliances are ideal for mid-market businesses that lack dedicated security resources and budget, but want protection from online attacks and productivity losses caused by spam and unwanted Web content. The Proventia M30 delivers a high level of protection for a significant value over stand-alone security solutions.

The Proventia M30 supports up to 500 users and is ideal for mid-size companies looking for industrial-strength protection without the associated costs or management headaches. The Proventia M30 can also be used to protect remote or branch offices and departments within enterprises and governments. The Proventia M50 integrated security appliance, also available, supports up to 2,500 users with the same combined security functionality.
