Virtual Private Network (VPN) is rapidly growing technology which plays a great role in Wireless LAN (WLAN) by providing secure data transmission. The purpose of VPN is to provide safe and secure communication by creating virtual tunnels between the pair of hosts; once the tunnel is created data transfer can take place. This paper presents a comprehensive study of VPN- IPsec and SSL VPN, architecture and protocols used. The salient of this paper to present comparison analysis of both technologies IPsec and SSL VPN. The VPN technology based on MPLS is the current mainstream VPN technology that uses isolations of routing and address or other information technologies to resist attacking and marking spoofing, in which the security of data transmission is guaranteed to a certain extent. Inthis paper, Securities of MPLS VPN are analyzed in three levels, in which the overall securities of MPLS VPN network are enhanced by deploying the appropriate security measures.
