The Netilla Security Platform (NSP) appliance is a 1-U high, rack-mountable server, running Netilla's proprietary Netilla dynaTRUST O/S, a comprehensive policy management and enforcement operating system for secure application access management. The NSP resides in the DMZ, typically behind the corporate firewall and in front of application servers. With the NSP, ease of maintenance is key: No integration or programming is required, while Netilla's Subscription Software Services deliver automated security and feature updates and upgrades.

As the industry’s most versatile SSL VPN, the NSP combines three application-access technologies into a single gateway device. The NSP is available in three performance classes designed to meet varying capacity needs, and can be modeled to support one, two or all three access methods.

NSP Security Zone
The NSP shields private network resources with application layer security. The NSP performs as a proxy that terminates, analyzes and processes all incoming user requests for authentication and policy before allowing any traffic to reach a secured resource. Once cleared, traffic is delivered to the appropriate access engine where it may undergo protocol translation that adds an additional layer of security for backend resources. Since the NSP enforces authentication and policy before allowing any data stream to reach the network, internal resources are effectively protected.

1. Secure Intranet Access through Web-Reverse Proxy
The NSP enables secure access to internal Web-based applications, intranet sites and portals with a proprietary Web Reverse Proxy technology. The NSP’s built-in HTML translation engine dynamical rewrites all user requested Web pages, obscuring the URL, network topology, and source code of the originating Web application. Also, since all requested pages are re-written, the NSP is able to filter potentially malicious Web components on an as-needed basis.

2. Clientless Access to Remote Applications
With no application client software required, and with just a Web browser, users can interact with actual applications that reside in the data center, in the same format as in the office – but within a browser window securely over the Web. When a user requests a remote application, the NSP functions as an application–layer proxy, translating the native protocol used by the server-based application into a thin-client application protocol for safe, fast transmission over the Internet. This remote application protocol also provides dynamic bandwidth optimization between the remote user and the NSP to insure greater application performance and enhanced user experience.

Supported Protocols:
- RDP for Windows applications
- X protocol for X Window applications
- Telnet or SSH for UNIX/Linux applications
- 3270 for Mainframes
- HTTP for Web servers

3. Client/Server Synchronization through SSL Tunneling
The NSP also allows users to work off line with local clients and “synch up” with remote servers over a secure SSL tunnel. When synchronizing these applications, such as Microsoft® Outlook, Lotus Notes, or customer relationship management (CRM) programs with a remote server, the NSP facilitates a secure, SSL session that "tunnels" HTTP traffic through complex firewall environments. The NSP facilitates this connection through the Netilla Virtual Adapter, an ActiveX component that automatically downloads to the user’s machine, offering remote connectivity to TCP- and UDP-based applications.

Additionally, the NSP proactively safeguards against unauthorized access by enforcing permissions-based policy that authorizes each user to synchronize specific local desktop applications with the remote server. Controlled by Netilla's SecureRealm Framework technology, the policy includes a dynamic session-based firewall that opens and closes ports on a per-user and per session basis.

Designed to insure VPN simplicity, the NSP’s client/server access only requires a single firewall port to the Internet and is compatible with environments that implement Network Address Translation (NAT). See Features and Benefits...
