Over the past few years, the number of cloud applications and devices that organizations use to connect to the internet has exploded. In turn, this has allowed employees to embrace remote working with Wide Access Networks (WANs) becoming a necessary tool to accommodate this.

However, with MPLS-based WAN services being provided by a third party, organizations face a challenge when it comes to cybersecurity. Many assume inbuilt security when implementing a Virtual Private Network (VPN) but the reality is that “private” doesn’t necessarily mean secure. With data breaches a significant issue as everything becomes increasingly connected, organizations cannot afford to rely on a third-party vendor to provide a totally secure network.

What is a VPN?

A VPN uses various protocols to connect a remote client to a private server over the internet and provides a level of security on public networks, for example so that employees can still connect to a work network “securely.”

However, the problem with VPNs is that they are not always private. The reality of VPNs is that a third party owns the network and they can run several wireless networks alongside each other, often on the same cable. VPNs are being sold as private, but as they use infrastructure that is running multiple VPNs, either by accident or attack, the VPN is not inherently secure.

This means that organizations must look to provide their own security measures for their VPNs, as they cannot rely on the third party to keep their data secure.

Step in Layer 4 Encryption

To address the security problem that stems from using third party providers, organizations must re-evaluate their Trust models. By taking away the assumption that devices and people using a VPN are automatically trusted, organizations can take back control of the security of their data.

This is where the Zero Trust model comes in. Championed by Forrester Zero Trust takes the view that nothing, not even users, are trusted, meaning that if a compromise happens, a hacker is severely limited in the data they can access because they are not trusted to access the entire network’s data.

In principle, this makes complete sense for enterprises however, the question is, how can organizations make this work in practice?

Certes’ Zero Trust WAN solution is designed to give organizations a simple way of implementing a Zero Trust model across their existing infrastructure. Certes’ patented Stealth Encryption technology encrypts at Layer 4 of the network, which complies with regulation and doesn’t compromise network performance. This allows organizations to provide a complete security solution for all users, regardless of where they are connecting to the network from. Having seen a number of big names suffer cyber security embarrassments in 2017 as a result of poor third part security, it is vital that businesses act now to take responsibility for the security of their entire infrastructure, regardless of the provider or implied, but in reality, questionable privacy.
