How to deploy remote access VPN
When you want to deploy a remote access VPN, there are two major modes to that end, which are the Secure Sockets Layer (SSL) and IP Security ( IPsec ). Each of these modes has its own pros and cons depending on the access requirements of the users or the organization.
SSL AND IPsec
Both IPsec and SSL VPN technologies provide access to every network application or resource. SSL VPN gives additional features like easy connectivity for remote user desktops, desktop application maintenance and also user-customized portals upon logging in.
Handling network security loopholes
Network security is a top priority. When IPsec and SSL VPNs are deployed as separate solution points, there are more endpoint security issues to consider. The only way to ensure complete security on your network is to maintain the unbreakable security of all the traffic going through your remote users and your VPN gateway.

While VPN is more widely used today and meets the general needs of interconnecting remote networks, it has several drawbacks when compared to a modern, secure remote access approach:
Benefits of Secure Remote Access
Although the complexity cannot be removed from current processes completely, a secure remote access solution requires far less technical knowledge than traditional VPN concentrators.
How to Know if Secure Remote Access Is Right for You
Knowing the benefits of secure remote access is meaningless unless you can identify opportunities to implement it in your applications or networks.
Conclusion
Although there are many remote access solutions on the market, most started as IT solutions and are now being shoehorned into industrial environments. Solutions such as these are complex for all administrators and users and a far cry from the simplicity offered by a sophisticated industrial secure remote access solution.
