Imperva Unveils Comprehensive Strategy to Enhance Data Security in the Cloud

Imperva Spinoff Incapsula Helps Hosters Offer Affordable, Enterprise- class Web Application Protection for Small and Medium Businesses

REDWOOD SHORES, California, December 6, 2010 - Imperva, the leader in data security, today unveiled a comprehensive
strategy to help cloud providers, enterprises and small to medium sized
businesses (SMBs) protect sensitive data against external and internal
threats and comply with regulations such as PCI, SOX and HIPAA. Additionally,
Imperva spinoff 'Incapsula' will help web hosters give SMBs affordable web
application protection. The Incapsula web application firewall service gives
small businesses an easy and affordable way to manage website security and
performance for any domain that they own even if it is hosted by a third
party. For hosters and other service providers, Incapsula enables website
security to be extended to an entire customer base. Imperva will resell this
service to complement Incapsula's own sales efforts.

"Cloud computing has created a paradigm shift in the way organizations
view their data center architecture," explained Imperva CTO Amichai Shulman.
"Imperva is stepping up to the challenge of protecting cloud-based data from
hackers and cloud insiders with a comprehensive data security solution."

"Incapsula's service helps web hosting companies provide SMBs with an
easy, affordable way to defend their web applications against external
hackers," explained Gur Shatz, CEO of Incapsula. "Given the nature of today's
indiscriminate, bot-based attack methods, small businesses are subject to
significant cyber attacks and require enterprise-class protection."

Subscribing to Incapsula's web protection service is a simple five-minute
process that does not require installation of hardware or software, just a
simple DNS change. Incapsula inspects all incoming traffic to any
subscriber's website, keeping hackers out while accelerating outgoing
traffic. The Incapsula service is suitable for the SMB and cloud market,
requiring minimal setup with service beginning in the first quarter 2011. The
list price for this service is expected to start at $50 per month.

Incapsula complements Imperva SecureSphere's cloud capabilities, such as
those leveraged by web hosting company, FireHost. "SecureSphere gives
FireHost a scalable web application security platform that can handle our
rapid customer growth. As part of our core service, all customers are
protected from web attacks using the SecureSphere Web Application Firewall.
We're also excited to offer premium data security services for HIPAA and PCI
compliance based on SecureSphere Database Activity Monitoring and File
Activity Monitoring products," explained Chris Drake, CEO of FireHost.

Imperva's high-level cloud capabilities include:

Attack Protection and Access Control for the Cloud: SecureSphere Web
Application Firewall (WAF) provides market-leading protection for cloud-based
web applications against complex and sophisticated attacks. SecureSphere WAF
enables a quick and easy route to PCI 6.6 compliance and the ability to
instantly mitigate known application vulnerabilities.

Data Access Auditing for the Cloud: SecureSphere Database Activity
Monitoring (DAM) and File Activity Monitoring (FAM) provide sensitive data
access auditing for cloud-based databases and file-sharing systems.

SecureSphere supports all major cloud deployment models and is available
by deploying physical or virtual SecureSphere appliances within a cloud data
center:

    - Infrastructure as a Service (IaaS) providers: IaaS providers offer
      state-of-the-art flexible and secure cloud data centers. SecureSphere
      enables IaaS providers to offer web attack protection and regulatory
      compliance readiness to their customers and generate incremental
      business. Imperva customers include Savvis and FireHost.
    - Platform as a Service (PaaS) providers: PaaS providers offer
      application development and delivery platforms that accelerate
      time-to-market of new applications and services. SecureSphere enables
      PaaS providers to give their customers web attack protection as part of
      the underlying platform.
    - Software as a Service (SaaS) providers: SaaS providers deliver
      cloud-based business applications for sales, financial, HR and other
      functional areas. These applications host large amounts of sensitive
      data across many organizations. As organizations adopt cloud
      applications to streamline their IT operations, SaaS providers are
      expected to ensure data security and address regulatory compliance --
      as would be the case for on-premise data.
    - Enterprise Private Clouds: Private clouds are a replacement or an
      extension of the traditional data center and must address the security
      of publicly facing web applications. SecureSphere Web Application
      Firewall (WAF) provides the industry-leading protection against
      Internet attacks targeting web applications and enables rapid
      mitigation of web application vulnerabilities.
