Skybox Security and Internet Security Systems Enter into Technology Alliance

Alliance combines the industry-leading Vulnerability Management and IPS solutions with the industry-leading Security Risk Management solution

SAN JOSE, CA — June 14, 2006 — Skybox® Security, Inc., the leader in Security Risk Management (SRM), and Internet Security Systems (ISS), the leader in preemptive enterprise security, today announced the formation of a technology alliance to bring clarity to customers’ network security postures and create more efficient risk management processes. Driven by customer demand, the technology alliance encompasses three distinct components: product integration between the Skybox View™ Platform and the ISS Proventia® Network Enterprise Scanner, ISS Proventia Management SiteProtector™ and ISS Proventia Network Intrusion Prevention System (IPS); sales referrals; and joint marketing cooperation.

Over the past two years, IT Security Risk Management (IT SRM) has emerged as the complete process of understanding threats, quantifying risk, prioritizing vulnerabilities, auditing security controls and reducing unnecessary patches through a continuously refreshed security risk profile. According to IDC estimates, the IT SRM market is expected to grow from $328 million in 2005 to $500 million in 2007.

“We are pleased to offer organizations a powerful one-two punch as part of their Security Risk Management deployments,” said Gidi Cohen, chief strategy officer for Skybox Security. “By tightly integrating vulnerability assessment with security risk modeling and simulation technology, enterprises can more quickly and accurately pinpoint the most critical vulnerabilities on their network, recommend the most efficient remediation steps, and continually refine the configuration of security controls.”

“Skybox View's unique virtual modeling and simulation capability, when used in combination with ISS’s Enterprise Scanner and SiteProtector, allows enterprises to better quantify security risks as well as create actionable intelligence that drives better decision making,” said Greg Adams, vice president, product management of ISS.

The technology partnership includes three joint business efforts to develop and promote the value proposition of the combined product offering:

• Product Integration: Delivering on the first phase of the relationship, Skybox has integrated the newly released ISS Proventia Network Enterprise Scanner and ISS Proventia Management SiteProtector with its flagship Security Risk Management Platform, Skybox View. Customers using the integrated solution will be able to reveal low ranking or previously unnoticed vulnerabilities that create a business exposure in order to refocus mitigation efforts. The combined solution will also allow customers to demonstrate decreased risk exposure over time and show continuous improvement of an organization's security posture.
  
  In addition to the integration with Enterprise Scanner and as part of phase two of the relationship, Skybox intends to integrate the ISS Proventia Network Intrusion Prevention System (IPS) product line with Skybox View's modeling, simulation and reporting capabilities during calendar year 2006. The combined solution is expected to provide customers with a comprehensive visual representation of the vulnerabilities averted through IPS.

• Sales Referrals: Skybox and ISS sales representatives will conduct joint sales calls to mutual customers who benefit from either an integrated product offering or the addition of one of the company’s respective solutions. When sold as a combined solution, special promotional pricing will be available.

• Joint Marketing: Skybox and ISS have agreed to conduct joint marketing programs including joint collateral and presentations, joint website exposure and promotion, and educational webcasts that promote the value proposition of the combined product offering.
