Santa Clara, CALIF. — April 7, 2003 - Sanctum, Inc., the established leader in Web application security solutions, today announced the 200th customer deployment of its award-winning application firewall, AppShield�. Customer number 200, Montgomery County Office of Family and Children First (OFCF), chose AppShield to protect the multi-jurisdictional database, which contains the county's most confidential information including the Domestic Violence Database. With its proven application security technology and growing user base across all major commercial industries and state and local government, Sanctum dominates the Web intrusion protection market, which is expected to reach $690 million in revenue by 2006.* In fiscal 2002, Sanctum increased total revenue by 65% and grew international sales by more than 500%.

"Due to the highly sensitive information being protected, such as the sex offender database and court records, application security is a business essential," said Ed McNachtan, Program Manager at Montgomery County OFCF. "Sanctum's reputation for providing the most reliable application firewall software made AppShield a logical choice for Montgomery County, as we expand our online presence to improve collaboration between social services agencies and law enforcement, furthering the ultimate goal to protect our citizens. With AppShield working 24/7 to defend our sites from dangerous cyber threats and hacker exploits, we are following through on our commitment to provide Montgomery citizens and county officials with a secure online environment."

Montgomery County OFCF is a partnership of government agencies and community organizations committed to improving the well-being of children and families. As part of their initiative to provide timely access to human services data for citizens, social service agencies, courts and law enforcement agencies, Montgomery county will deploy AppShield as an integral part of their cross-agency automated information system.

"Our flagship product AppShield has matured over the last five years as both a standalone and appliance-ready application firewall, and continues to be the most trusted application security technology on the market," said Peggy Weigle, CEO of Sanctum, Inc. "Today's legislative and corporate policies demand a technically superior and trusted solution to protect confidential personal data and intellectual property. Since the introduction of AppShield in 1999, we've driven innovation and product enhancements that meet not only current customer needs, but will grow with enterprises to meet future requirements. Through ongoing OEM partnerships for integrated solutions, we are confident that AppShield will continue to dominate the application firewall market."
