With VPN or virtual private networking, there is a safe way for mobile workers to connect to the company's local area network to access their essential resources. The VPN options available are numerous, while there are some that require additional software and hardware, there are other that are built in the operating system. SSL VPN enables anytime, anywhere secure remote access for employees, customers and strategic partners to business-critical resources thereby increasing corporate productivity and lowering IT overhead. The growing technology has given enterprises the flexibility of choosing the best SSL VPN solution to suit their needs.

Slide 1: IPSec VPN Vs SSL VPN
Wikipedia defines Virtual Private Network as “a private computer network that interconnects remote (and often geographically separate) networks through primarily public communication infrastructures such as the Internet . A VPN could be used to securely connect the branch offices of an organization to a head office network through the public Internet. A VPN can also be used to interconnect two similar networks over a dissimilar middle network.” The growing popularity of VPNs is due to the fact that it reduces costs considerably as it uses existing infrastructure to provide secure and private communication. Hence, there is no need of dedicated leased lines. VPNs are of several types namely Internet Protocol Security (IPSec) Secure Sockets Layer (SSL VPN) Transport Layer Security (TLS) Datagram Transport Layer Security (DTLS) Microsoft Point-to-Point Encryption (MPPE) Secure Socket Tunneling Protocol (SSTP) Multi Path Virtual Private Network (MPVPN) Secure Shell (SSH)
Of the different VPNS, the most widely used are IPSec and SSL VPNs. An IPSec offers great security and meets most security goals namely authentication, integrity, and confidentiality. As far as SSL VPNs are concerned, it provides remote users with access to web applications, client/server applications, and internal network connections. Though IPSecs are one of the most widely used VPN protocols for site-to-site access, SSL VPNs are much popular today. Hence, let’s look at the fundamental differences between the two in order to understand the growing popularity of SSL VPNs. Internet Protocol Security (IPSec) VPN To access IPSec VPN, third-party hardware / software is required An IPSec client software application need to be installed and configured on all remote machines In IPSec protocols, maintaining the licenses for the client software can turn to be a financial burden for enterprises IPSec connectivity can be impaired by firewalls, routers, and proxy devices IPSec deployment is not easy due to complications from Network Address Translation (NAT) All resources on the network is exposed and therefore requires complex ACL management In case of IP conflicts, complicated NAT and IP Mapping required
Secure Sockets Layer (SSL) VPN It can be used with a standard Web browser. Without any specialized client software, it ensures secure remote access Only needed resources are exposed IP conflicts are automatically resolved No need to open firewalls for SSL traffic as it is allowed by default
Moreover, SSL VPNs require no pre-installed clients, support a broad range of access methods, provide encrypted connectivity and end-point security, and offer industry-leading scalability and price-performance. All this contribute to its growing popularity. Also read about : Bring Your Own Device & Remote Desktop access
