![]() ![]() With zero trust, by contrast, even trusted identities and devices do not receive full network access. When it comes down to it, VPNs are inherently insecure: VPNs group all users into one system and if an attacker gains access the entire system is compromised. With that in mind, here are three common VPN-related challenges that a zero trust approach can alleviate: )Īs employees explore alternative work-from-home locations, while diversifying the types of devices and applications they use, VPNs are already proving unable to meet either demand or security requirements.

At the same time, attacks are becoming more sophisticated and difficult to prevent-another reason to implement strong authentication and identity-based access controls like zero trust. Today, remote work is at an all-time high, global connectivity is expected and the number of networks and connections that cyberattackers are eager and ready to take advantage of has exploded. Though perimeter-based network security was a viable solution in the past, it’s been clear for several years that this approach cannot keep up modern workforce trends-and the pandemic only accelerated this reality. Each user’s level of access, and the actions they are permitted to perform, is defined and enforced according to the organizational policy. Only after a user is authenticated can they get access to applications, content or systems-and even then, their identity is continuously authorized to check for unusual behavior or attributes. Gone are the days of “If you’re inside the network, that means you can be trusted.” With zero trust, everything is based on identity. Instead of establishing a small perimeter within the network, zero trust protects the entire network’s security-and, more specifically, the information assets within it-by individually verifying each user and device before granting access to a given application. The zero trust approach works in direct contrast to the VPN model. (Also read: Considering a VPN? Make the Right Choice for Your Needs. As such, traditional VPNs assume by design that anything that passes through the established boundaries can be trusted. This limited access to the entry point acts as the prime security measure. ![]() Only users who have access to the VPN are able to interact with anything inside the perimeter. In turn, VPNs operate within a network-rather than protecting the network itself. A traditional VPN works by establishing a perimeter around assets in a network or certain network activity. ![]()
