Technology to achieve the strength of SSL VPN is precisely the weak point of IPSec VPN, SSL VPN only need to open the commonly used 443 ports, no complex configuration, and IPSec VPN is often limited by the impact of the network environment, may require a relatively large configuration. For SMB, SSL is cheaper, easier to maintain, and requires less employee training.
