IPsec – the preferred VPN technology

The Internet Engineering Task Force's (IETF) IPsec-specification is the latest protocol standard for the set-up of IP-VPN's. It is known to be technically mature and provides a perfected method for external business communication in unprotected public networks. Additionally, the future IPv6 contains IPsec as its basic technology.  

All VPN solutions, which are currently available, contain IPsec functionalities. However, there are differences in IPsec solutions. The decisive factor for the quality of a solution is, which kinds of IPsec protocols the supplier supports. By only implementing proprietary protocol expansions of the IPsec protocol for remote access, the user is led nowhere. As early as 2002, NCP developed an IPsec protocol-stack, which matches all the IETF objectives and supports all IPsec standards according to RFC.   

Security solutions, based on IPsec VPN technology, have to support all peripheral and central components as well as systems in all remote access environments - this is the standard the user can expect, hence, this is the standard a solution has to meet. In order to meet these standards and in order to optimize for remote access, NCP has expanded the IPsec-stack by special protocols (e.g. XAUTH, IKE-Config-Mode, NAT Traversal (NAT-T), Dead Peer Detection (DPD). 

NCP's Next Generation Network Access Technology allows for highly secure IPsec VPN connections behind firewalls, whose settings are designed to prevent IPsec based data communication (e.g. in a hotel). The technology behind this feature is called NCP's VPN Path Finder Technology. 

Strong authentication via one-time password token (OTP), certificates or biometric data via PKCS#11 is a further security feature of NCP's Secure Communications Solution. The solution supports both, user and / or hardware certificates. Click here for further information.
