Comprehensive solution includes vulnerability assessment, intrusion detection, and threat management for securing data

ATLANTA and HOUSTON – July 21, 2010 Internap Network Services Corporation (NASDAQ: INAP), a leading provider of end-to-end Internet business products and services, today announced that it has entered into a reseller agreement with Alert Logic to add a new layer of comprehensive security services to its Managed Hosting portfolio. Alert Logic is a leading provider of cloud-powered security solutions including vulnerability assessment, intrusion detection and threat management for enterprises and IT service providers.

Enterprises continue to struggle to balance the need to secure networks and applications with the cost and complexity of operating and maintaining security systems. In this environment, managed security services have emerged as an ideal solution for small to medium enterprises. Alert Logic has extensive experience delivering security services from the cloud to over 1,000 customers across multiple vertical markets. Its patented technology adds a new layer of security functionality to Internap’s Managed Hosting offering, delivering vigorous security and compliance that is monitored and managed 24/7. Alert Logic’s technology addresses some of the most complex and expensive regulatory requirements experienced by service providers and enterprises.

“With security threats and compliance requirements constantly evolving, our cloud delivery model ensures customers always have the latest protection without having to manage patches, content updates, or software upgrades on their own,” said Gray Hall, CEO at Alert Logic. “This agreement with Internap creates a powerful combination of our advanced technology with a high-performance hosting services provider to ensure customers never have to compromise between security and performance.”

Internap’s Managed Security offering can be delivered over dedicated or multi-tenant infrastructures. It is easily accessible through Internap’s existing customer portal through which customers can view an all-in-one security dashboard with rich reporting tools to support IT initiatives and compliance (PCI, SOX, HIPAA, GLBA, etc.) requirements.

“Security is a vital consideration for any enterprise considering a managed hosting solution, and the technology is a natural complement for Internap’s storage, data protection and virtualization features,” said John Freimuth, vice president of managed hosting services at Internap. “Alert Logic’s leading technology and comprehensive dashboard gives our customers a consolidated view of both security and compliance backed by continuous monitoring and management.”

Internap’s Managed Security service based on Alert Logic’s technology is available now from the company’s Managed Hosting locations in North America, Europe and Asia. For more information, call 1-877-THE-PNAP or visit http://www.internap.com/managed-hosting.
