Sponsor Micro-site: NeoAccel SSL VPN Plus™

Better Than IPSec VPNs ... AND Conventional SSL VPNs

NeoAccel's SSL VPN-Plus is a unique secure remote access gateway that delivers all the benefits of SSL VPNs including mobility, ease-of-use, policy-based fine access control and zero-client administration PLUS the low latency, high data throughput and universal application support previously available only with IPSec-based solutions. PLUS, the NeoAccel security appliance enforces endpoint security policies - a network admission control (NAC) capability rarely built into SSL VPN gateways.

  • Users can securely connect from anywhere through web-installed software on Windows 2000/XP, Mac OS X and Linux devices.

  • The configuration, management and support complexities of IPSec VPN clients are completely eliminated

  • All application protocols (IP, UDP, TCP, etc) are supported with a single downloadable agent

  • User access privileges can be selectively limited to individual subnets and application servers

  • Applications like VoIP that require low latency run flawlessly even in a wireless environment

  • Devices must fully comply with security policies before network access is
    permitted

  • Devices are continuously scanned for malicious code and open ports


Innovative NeoAccel Technology

Intelligent Connection Acceleration Architecture™ (ICAA™). Conventional full-access SSL VPNs tunnel TCP/IP data in a second TCP/IP stack for encryption over the Internet. This results in application layer data being encapsulated twice in two separate TCP streams. When packet loss occurs which goes on even under optimal Internet conditions, a performance degrading effect called "TCP-over-TCP meltdown" happens. In essence two TCP instruments are correcting a single packet of IP data, undermining network throughput and causing connection timeouts. NeoAccel's patent-pending ICAA technology eliminates this TCP-over-TCP problem, ensuring optimal performance.
Transparent SSL Engine™ (TSSL™). NeoAccel's TSSL engine provides tightly coupled SSL processing with network traffic. Our SSL engine encrypts and processes SSL connections at the kernel level, communicating directly with a system's TCP stack and SSL hardware accelerator. This enables optimal performance, by-passing overhead associated with most user-mode SSL VPN implementations. It also allows scalable performance of up to 20,000 concurrent users without affecting response time.
Acceleration Triggered Compression Engine™. Conventional compression mechanisms fail to account for the tradeoff between the time-taken to compress the data versus the time to send the uncompressed data. Consequently, many compression engines actually hinder application performance. However, NeoAccel’s acceleration triggered compression engine utilizes a unique algorithm to determine when compression would be optimal. The result is VPN throughput that is often equal to wire-speed, unencrypted network connections.
