As a developing VPN technology, SSL VPN is rapidly gaining popularity. Compared to traditional IPSec VPNs, SSL VPN is a better solution for remote access by mobile users, whereas IPSec VPN is more suitable for connecting between networks (gateways).
As a network administrator, the most important thing is to carefully consider what type of network service your users really need and then choose the solution via https://www.vpnacademy.com/freevpn/ that works best for you.

Hence, both technologies will share the commercial market in the future. In particular, there are some differences between the two:
SSL VPN operates at the transport layer of the OSI network model, on the other hand, IPSec VPN is a network technology based on the network layer of the OSI model. Hence, IPSec VPN guards all IP-based applications, meanwhile, SSL VPN promotes the safety of web-based applications.
SSL VPN tunnels can pass through firewalls, regardless of the WAN technology used. To ensure that an IPSec VPN can bypass the firewall, the IPSec client must support the "NAT penetration" function and port 500 (UDP) must also be enabled on the firewall.
In a network that implements SSL VPN, only the gateway equipment at the central node needs to be served, which significantly reduces configuration and maintenance costs. Meanwhile, a network that implements IPSec VPN requires support for each node.
SSL VPN provides more granular control over user access, more flexible control over user rights, resources, and files, and is easier to integrate with third-party agencies such as Radius and AD. With IPSec VPN, user access control is implemented by checking five network parameters such as source port, source IP, protocol, destination port, and destination IP address.
