Why Should Organizations Opt for Zero Trust Solution than a VPN

A VPN (Virtual Private Network) is an internet security service that enables an encrypted connection between user devices and one or more servers. VPNs main functionality is to allow a user to connect a company’s internal network or public internet securely. 

That said, VPNs are traditional method of establishing a secure connection and are being replaced by a smarter, safer approach to network security that treats every access as “untrusted.”

The reputable technology (VPN) that was discovered decades ago is facing extinction as enterprises migrate to a more agile, granular security framework called zero trust which better adapts to today’s world of digital business. VPNs were innovated as a part of a security strategy based on the concept of a network perimeter, trusted employees are on the inside and untrusted employees are on the outside.

But that model no longer works in the modern business environment, since enterprises have migrated most of their digital assets, apps, data, tools to the cloud; employees can access them from any location using any device. The digital assets are no longer stored inside the walls of the enterprise data center but in multi-cloud environments.

Gartner predicts that by 2023, 60% of enterprises will eliminate most of their VPNs in favor of Zero Trust Network Access that functions as a gateway or broker that authenticates both device and user before granting role-based, context-aware access.

This is why organizations opt for a solution alternative to vpn so that they can not only have a secure channel but also secure end-points, apps, tools and other resources in the cloud.

The perimeter approach to security has a variety of flaws, since it doesn’t address insider attacks, it doesn’t do a good job considering contractors, third parties and supply-chain partners. If an attacker steals an employee’s VPN credentials, the attacker can easily access the network and incur a mishap. Moreover, VPNs over the long run have become complex and hard to oversee.

The idea of Zero Trust Security Framework is simple: Trust no one. Verify everyone.

Implementation of Zero Trust accomplishes several things: 

Decreases your overall attack surface since cloud resources are exposed to users for limited use.

  • Also limits lateral movement or “leapfrogging” to other vulnerable infrastructures once one endpoint is breached.
  • The possibility of stealing credentials and unauthorized access is limited, be it by employees or outside sources such as dark web.
  • To conclude, Zero Trust makes the organization’s digital assets in cloud harder to breach so that attackers will give up and try someone else when they fail to initiate attack to access the cloud.

The threat from cybercriminals are rising every year this causes a heavy burden considering the cost and reputation to businesses, hence more and more organizations that use internet, sync their daily activities to the cloud, provide devices or allow personal devices for employees are seeking methods to implement a Zero Trust Model. 

Zero Trust usability is more than any traditional VPN technology, IT teams can evaluate various technical solutions for implementing Zero Trust. Below are a few more details to understand the importance of Zero Trust Security Architecture for your business:

Threats can occur from inside as well as outside:

The traditional castle-and-moat approach is no longer imminent. Earlier, IT security has been focused on the perimeter of the organization with an idea to safeguard those digital assets inside the organization. However, with the migration to the cloud businesses should consider protecting their cloud not just within the organization but also from those attempting to access cloud from any location.

Implement micro-segmentation: 

With micro-segmentation IT teams can segment even inside the firewall areas of the organization. Employees from a particular department can access tools and data that they use daily but can’t access other departments tools & data. 

Assign least privileged access

This functions just like micro-segmentation just that it limits users from accessing all information. Employees within the department need not have all the access to the cloud, depending upon the role he or she may only need to access a particular set of data, apps and tools.

No matter where the access request is from; the Zero Trust Security Model grants access only after verifying the source. It allows IT teams to enforce strict access-control and identify-management policies that restrict access to the cloud, applications, tools, etc.

Zero Trust has the potential to radically alter the way security is done, but with VPNs, you don’t get the same liberty.
