Network security has undergone significant transformations over the past few decades, shifting from basic firewalls and antivirus software to more sophisticated security strategies to defend modern, complex network infrastructures.

Traditional network security often relied on perimeter-based defences, where everything inside the network was trusted, and all security efforts were focused on keeping threats outside.

However, the rise of cloud computing, mobile access, and increasingly sophisticated cyber threats exposed the limitations of this model.

As breaches continued to occur even with robust perimeter defenses, the security community began to advocate for a more holistic approach to network security, leading to the development of the Zero Trust network architecture.

Zero Trust architecture eliminates the concept of trust based on network location within or outside the perimeter. Instead, it requires all users, whether in or outside the network, to be authenticated, authorised, and continuously validated for security configuration and posture before being granted or accessing applications and data.

What is Zero Trust Network Architecture (ZTNA)?

Zero Trust Network Architecture is a security concept centred on the belief that organisations should not automatically trust anything inside or outside their perimeters and instead must verify anything and everything trying to connect to its systems before granting access.

The strategy dictates that only authenticated and authorised users and devices can access applications and data. Moreover, access is limited to just the resources necessary for a particular task at any given time.

This approach uses technologies such as multifactor authentication, identity and access management (IAM), orchestration, analytics, encryption, scoring and file system permissions, and security policies to determine access decisions.

Zero Trust architectures make the assumption that there are attackers both within and outside of the network, which makes security consistent and potentially more stringent throughout.

Zero Trust VPNs: A New Approach to Private Networking

Virtual Private Networks Redefined

Zero Trust VPNs are a newer development that redefines traditional VPN technology by integrating Zero Trust principles.

Unlike conventional VPNs that might grant extensive network access once a user is connected, Zero Trust VPNs apply strict identity verification and limit users to access only specific applications or services for which they have permissions.

One of the key features of today’s modern workforce is the ability to protect devices no matter where they are and protect resources no matter where they are, including in the cloud.

Continuous Trust Assessment

Zero Trust VPNs continuously assess the trustworthiness of each session, applying adaptive security policies based on user identity, device, location, and other attributes.

This ongoing evaluation ensures that any change in the security posture or anomalous behavior can trigger real-time adjustments to access rights, thereby enhancing security. It can also involve a series of penetration testing strategies.

Application-Level Access Control

This approach moves away from network-centric access controls to application-centric ones. Users connect not to a network, but directly to applications, minimizing lateral movement within the network and reducing the attack surface.

Each application access session is treated as a unique, auditable event, ensuring greater visibility and security.

Empowering Organisations with Zero Trust Architecture

Implementing Zero Trust Network Architecture and Zero Trust VPNs empowers organizations to tackle modern cybersecurity challenges more effectively.

By assuming a breach is always possible, Zero Trust strategies enforce stringent access controls and continuous verification, enhancing security across all users, endpoints, and network resources.

This architecture supports the demands of a modern workforce, including remote work and BYOD policies, without compromising the security of sensitive information.

Zero Trust strategies enhance security and improve compliance with data protection regulations by providing detailed insight and control over how data is accessed and by whom. It should also include mobile device management to ensure the network is protected even when accessing from your mobile phone or iPad.
