Therefore, even if a user was able to access the network (through VPN or any other manner) this does not mean they should see all the network assets or have automatic access to them. It assumes that attackers exist outside and inside the network. Zero trust (ZTNA – Zero Trust network access or ZTA – Zero Trust Access) is a new security model that is based on the premise of trusting no one (in the network). That being said, it is recommended to complement VPNs with another security solution, to protect from internal threats. Capping the traffic will help with ensuring higher performance and reduce IT overhead. VPNs can be used in organizations that require a limited extent of remote connectivity for their employees or branches. Their castle-and-moat approach and technical vulnerabilities that are common in VPNs makes them a component that increases the attack surface. In addition, setting up VPNs is a difficult process that requires a lot of overhead from IT teams and users, as VPNs require setting up a client on the end-user’s device.īut more importantly, VPNs are not a secure access solution. VPN traffic is often encrypted, and is considered slow and with high latency. Once users are in, they can see and access the entire network. VPNs authenticate users from outside of the network, and then tunnel them inside. (Most of the devices we have today were still in the making). VPNs were a new network access approach approximately two decades ago, when companies needed a solution for connecting branches or workers who were occasionally working remotely from a desktop computer. This blog post will explain each one and when you should choose it for your organization. Three of the most debated technologies are Zero Trust (ZTNA or ZTA), VPNs, and SDP. As a result, organizations are trying to find better cybersecurity solutions that will protect their networks, applications and information. Network and communication needs are rapidly changing and the number of sophisticated cyber security attacks is increasing.
