Increase Productivity and Ensure Security with SSL VPNs

In today’s business environment, where consumerization of IT has resulted in the popularity of the concept of Bring Your Own Device (BYOD), employees, partners, customers, contractors and guests want remote access to business applications anywhere at any time. Though ensuring remote access helps enterprises to increase productivity, it is highly necessary that enterprises make sure that security and compliance are equally maintained. With security breaches being a serious issue, enterprises must ensure secure remote access so that authorized personnel can quickly access the resources and applications without compromising on security. That is where Virtual Private Networks (VPNs) come useful.

 

A VPN is defined as “a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network.” Simply put, VPNs allow organizations to send and receive data across shared or public networks by creating a private or secure network over the public network. That means with VPN, public networks get all the functionalities, security and management policies of the private network but at a much lower cost.

 

Traditional VPNs rely on IPSec (Internet Protocol Security) to establish a secure tunnel between the two endpoints. However, today mostly SSL VPNs (Secure Sockets Layer Virtual Private Networks) are used. This is because apart from offering versatility and ease of use, SSL VPN does not require the installation of specialized client software on the end user's computer. The versatility and granular control for a range of users from any Bring Your Own Device - BYOD and any location is what SSL VPN offers the clientele.

 

Here is a look at some of the benefits of using a best of breed SSL VPN solution.
