There are two types of VPN that we are commonly using, and both are secured but implemented and used in different ways. Lastly, VPN is scalable in that you can add unlimited tunnels and users. VPN also provides security for all the traffic that is sent outside your network through VPN tunnels.
Using VPN will cost you nothing as it is completely free since most organizations have firewalls already installed with a built-in VPN feature. VPN replaces the dedicated point-to-point link with the emulated point-to-point link or secure connection that shares the common infrastructure. All the network traffic that is sent through the VPN tunnel will be encrypted and kept confidential from hackers on a network or the internet. Cisco VPN solutions are offered as well.Ī Virtual Private Network (VPN) is an encrypted tunnel between two or more devices, usually a firewall, such as the Cisco Adaptive Security Appliance (Cisco ASA), over an unsecured network such as the internet. The best and cheapest option to protect our data in transit is by using Virtual Private Network (VPN). Data in transit is more vulnerable to attacks as the data will travel outside your protected network. There are three states of data that we need to protect – data at rest, data in use, and data in transit. Security is compulsory in today’s generation because of emerging threats initiated by hackers ready to compromise your network and resources.
