SAN JOSE, Calif.--(BUSINESS WIRE)--Feb. 20, 2002

CacheFlow(R) Inc. (Nasdaq:CFLO), a leading provider of secure content networking solutions, today made multiple product, technology, and partnership announcements signaling the company's move to address the emerging security gateway market opportunity. The estimated $1.4 billion market is being driven by customers requiring security, control, and acceleration for their web security infrastructure -- beyond the capabilities provided by traditional firewalls, proxy servers and caching devices. Leveraging existing investments in web and security infrastructure, the new products, partnerships and technologies will enable businesses to increase web security and reduce management and administration costs. Customers will utilize the new CacheFlow Security Gateway and related products to deploy web security applications such as authorization management, content filtering, web usage monitoring, virus scanning, content security, and network bandwidth protection.

"Our new focus is a culmination of understanding our business, our core expertise, and what our customers care about," said Brian NeSmith, CacheFlow president and chief executive officer. "Our new strategy and products address what we believe is a new layer of security infrastructure for web applications that blends policy-based security and protection functionality with the traditional control of the proxy server and the content acceleration of the cache."

"CacheFlow has brought together the right mix of policy-based security and manageability to help us reduce risk in our Internet infrastructure," said Greg Johnson, vice president, Information Technology, AON Insurance. "As a result of the CacheFlow Security Gateway, we've been able to effectively control Internet access, confidently deploy reliable web services, and enable our organization to act rapidly to limit our exposure from threats such as nimda."

"CacheFlow has gained a great deal of experience over the past several years in deploying scalable, secure content delivery solutions for the web." said Lucinda Borovick, director, IDC. "The concept of integrating critical network elements of security, control and performance is exciting given the continued adoption of web applications and services."

Comprehensive Security Solutions

In related product and partner announcements, CacheFlow today also announced the availability of several new products, an extended partnership and new products with Secure Computing, and interoperability with leading virus scanning solutions:

-- New Security Products -- CacheFlow introduced (4) new products including
CacheFlow Security Gateway, Visual Policy Manager, CacheFlow Reporter, and
cIQ(TM) Director 2.0. Together, these products provide powerful web security
for enterprises.

-- Extended Partnership with Secure Computing -- CacheFlow has integrated
SmartFilter(TM) v3 Web filtering "on-box," enabling new category-based
synergies with the Security Gateway security policy architecture. The
SmartFilter "on-box" plug-in architecture requires no additional hardware, and
delivers large performance, cost and bandwidth improvements over
non-integrated, multibox deployments. CacheFlow's "pass-though" design is the
most reliable and scalable in the industry.

-- Interoperability with Virus Scanning Software -- CacheFlow has announced
interoperability with leading virus-scanning solutions from Symantec and Trend
Micro. As an integral part of an enterprise security infrastructure, the
CacheFlow Security Gateway utilizes the standards-based Internet Content
Adaptation Protocol (ICAP) to control viruses over web protocols -- before they
infect the network.

Pricing and Availability

The complete portfolio of CacheFlow Security Solutions will be available in March through CacheFlow and its global network of channel partners. Pricing varies based on model and configuration. Please contact CacheFlow or any authorized partner for additional information.
