VPN security equipment Juniper

Networks Secure Access 4500 Base System - 2x RJ-45 10/100/1000 Full/Half-Duplex, 1U The Juniper Networks® SA2500, SA4500, and SA6500 SSL VPN Appliances meet the needs of companies of all sizes. SA Series SSL VPN Appliances use SSL, the security protocol found in all standard Web browsers. The use of SSL eliminates the need for pre-installed client software, changes to internal servers, and costly ongoing maintenance and desktop support. The SA Series also offers sophisticated artner/customer extranet features that enable controlled access to differentiated users and groups without requiring infrastructure changes, demilitarized zone (DMZ) deployments, or software agents.
The SA Series includes Juniper Networks Junos® Pulse, a dynamic, integrated, multiservice network interface for mobile and nonmobile devices. Junos Pulse enables optimized, accelerated, anytime, anywhere access to corporate networks, clouds, and the data they hold. Junos Pulse enables secure SSL access from a wide range of mobile and nonmobile devices, including smartphones, tablets, laptops, and desktop PCs, as well as Wi-Fi or 3G/4G and Long Term Evolution (LTE)-enabled devices. Junos Pulse delivers enterprises improved productivity and secure, ubiquitous access to corporate applications and data—anytime, anywhere.

Architecture and Key Components
The SA2500 SSL VPN Appliance enables small to medium-sized businesses (SMBs) to deploy granular, cost-effective mobile and remote network and cloud access, as well as intranet security and business continuity in case of disaster or emergency. Users can access the corporate resources and applications from any endpoint device over the Web. The SA2500 offers high availability (HA) with seamless user failover. And because the SA2500 runs the exact same software as the larger SA4500 and SA6500, even smaller organizations gain the same high performance, administrative flexibility, and end user experience.
The SA4500 SSL VPN Appliance enables mid- to large-sized organizations to provide efficient, role-based corporate network, cloud, and application access to mobile and remote employees, as well as authorized contractors and partners, requiring only a Web browser connected to the Internet. The SA4500 features rich access privilege management functionality that can be used to create secure customer/partner extranets and to enable secure access to the corporate intranet, so that employees and other
authorized users can use the same access means but with differentiated, role-based access while still adhering to enterprise security policies. Built-in compression for all traffic types speeds performance, and SSL acceleration is available for more demanding environments. The SA4500 also offers HA with seamless user failover.

The SA6500 SSL VPN Appliance is purpose-built for large enterprises and service providers. It features best-in-class performance, scalability, and redundancy for organizations with high volume secure access and authorization requirements. Additionally, the SA6500 offers HA with seamless user failover.
The SA6500 also features a built-in compression for Web and files, and a state-of-the-art SSL acceleration chipset to speed CPU-intensive encryption/decryption processes. Because each of the SA Series SSL VPN Appliances runs the same software, there is no need to compromise user or administrator
experience based on which appliance you choose. All devices offer leading performance, stability, and scalability. Therefore, deciding which device best fits the needs of your organization is easily
determined by matching the required number of concurrent users, and perhaps system redundancy and large-scale acceleration options, to the needs of your growing mobile and remote access user population.

SA2500: Supports SMBs as a cost-effective solution that can easily handle up to 100 concurrent users on a single system or two-unit cluster.
SA4500: Enables mid-sized to large-sized organizations to grow to as many as 1,000 concurrent users on a single system, and offers the option to upgrade to hardware-based SSL acceleration for those who demand the most performance available under heavy load.
SA6500: Purpose-built for large enterprises and service providers, the SA6500 features best-in-class performance, scalability, and redundancy for organizations with high volume secure access and
authorization requirements—with support for as many as 10,000 concurrent users on a single system or tens of thousands of concurrent users across a four-unit cluster.
