The Role of VPNs in Today’s Enterprise Cybersecurity

VPNs are playing an ever growing role in securing enterprise level cybersecurity. These networks are used to create a secure and encrypted connection between a user’s device and a remote server or network. This provides two key benefits for protecting enterprise data.

TLDR: VPNs are a vital component of enterprise cybersecurity protection, helping to keep company data safe and secure from unauthorized access. They provide an extra layer of defense against malicious attacks, while also making it more difficult for attackers to intercept or spy on transmitted data.

High Level Encryption

VPNs make it much more difficult for hackers to intercept and spy on data being transmitted. They use powerful encryption methods to protect the data and prevent unauthorized access, making it more difficult for attackers to intercept or steal information through a network connection.

VPNs are essentially designed to protect networks by utilising high quality encryption.

Thus ensuring data being transmitted across a network can be secured and won’t be intercepted by malicious actors.

There are three main ways that VPNs provide this level of protection:

  1. They use strong security protocols like AES-256 or AES-128 in order to provide strong encryption.
  2. They use secure tunneling protocols like IPSec or SSL/TLS to securely transmit data packets across a network. 
  3. They employ strict access controls and authentication measures to limit who can access the network and what they are able to do while connected.

By using these methods, VPNs help ensure that sensitive information remains confidential and cannot be compromised by hackers or other malicious actors.

Layering Entry Points

VPNs add further to enterprise network security by creating an additional layer that must be breached in order to gain access. (VPNs are designed to protect networks by layering entry points, or points where users can connect to the network). 

This helps prevent attacks from getting in through other entry points, such as vulnerable software or network devices.

Traffic encryption is pertinent here again in order to secure traffic between the user’s device and the VPN server thus preventing malicious third parties from intercepting and reading sensitive information as it travels across networks.

Another place to look is at the firewall. The best VPNs often use a firewall to filter incoming and outgoing traffic, ensuring that only authorized users and devices can access the network. This layer is passed on to whichever enterprise network is using it.

An additional and often overlooked layer is two-factor authentication. VPNs typically use two-factor authentication to ensure that only authorized users can access restricted data. These three strategies work together to protect networks by layering entry points and ensuring that only authorized users can connect.

Undenial Importance of VPN Technology

VPNs are an essential tool for protecting networks by layering entry points and preventing unauthorized access. Their encryption, firewalls, and two-factor authentication help to secure sensitive data and prevent malicious actors from gaining access to critical systems and information.

While enterprise level cybersecurity is very multi-faceted and comprises many different resources, tools and technology in order to develop a robust response to attacks, it is undenial that the VPN technology we have today is a key component of a cybersecurity arsenal.
