Implementing Zero Trust

Awareness of network security threats is more critical than ever.

As users and devices grow more distributed and threats become more sophisticated, outdated perimeter-focused security is no longer sufficient.

The time to act is now.

Modern approaches like Zero Trust and SASE frameworks are now essential to safeguard organisations against evolving risks and increasingly complex attack methods.

Businesses are seeking reliable, integrated solutions to secure hybrid workforces, IoT proliferation, and cloud-based operations.

By adopting and offering HPE Aruba Networking’s Security-First, AI-Powered architecture, resellers position themselves as trusted advisors, able to deliver innovative, future-ready solutions that meet customer demands and compliance needs before competitors can.

What is SASE?

SASE – or Secure Access Service Edge – is a security framework that converges networking and security functionalities into a unified, cloud-delivered service. SD-WAN and SSE (Secure Service Edge – which is made up of ZTNA Zero Trust Network Access, CASB Cloud Access Security Brokers, SWB Secure Web Gateway and DEM Digital Experience Monitoring) is what makes up Unified SASE.

By integrating components such as SD-WAN, secure web gateways, cloud access security brokers and zero trust network access, SASE delivers secure, seamless connectivity for users and devices regardless of location.

This approach is designed to support distributed workforces and applications by enabling consistent security enforcement and optimised performance across campus, branch, remote and cloud environments.

What is Zero Trust?

Zero Trust is a security model that operates on the principle that no user, device, or network segment should be inherently trusted, whether inside or outside the traditional perimeter.

Instead, it requires continuous verification of identity, strict access controls based on roles and context, and proactive monitoring of network activity.

With Zero Trust, organisations enforce least-privilege access, segment resources, and mitigate the risk of insider threats or advanced attacks, ensuring that every access request is evaluated and granted only as necessary.

Key advantages of Zero Trust from HPE Aruba Networking include:

Stronger security posture with granular access control.

ZTNA enforces least-privilege access by verifying users and devices before granting access to specific resources – not the entire network. This reduces the attack surface and helps prevent lateral movement in case of a breach. It’s especially valuable for hybrid workforces and third-party access.

Simplified and scalable remote access.

Unlike traditional VPNs, Aruba ZTNA provides secure, seamless access to applications regardless of location – without the complexity of managing VPN tunnels. It scales easily across distributed environments, making it ideal for modern enterprises with remote users, branch offices, and cloud-hosted apps.

Improved visibility and control for IT teams.

ZTNA integrates with HPE Aruba Networking’s unified infrastructure to deliver real-time insights into user behaviour, device posture and application usage. This enables proactive threat detection, policy enforcement and compliance reporting — all from a centralised platform.

Learn More

VPN alternative for ‘work from anywhere’.

Use ZTNA to replace remote access VPNs that are typically used to connect remote users to a network, and deliver a faster, more secure experience while doing so.

In-office employee access.

Avoid inherently trusting on-premises users, and leverage publicly hosted Zero Trust brokers, or private brokers deployed within your own environment, for least-privilege access with simpler segmentation, faster user experience, easier compliance.

Securing third-party access.

Use agentless access to securely enable business ecosystem partners, suppliers, vendors and customers to access critical business data, without granting access to the entire corporate network.

Accelerate IT integration during M&A or divestitures.

ZTNA helps accelerate the process of each down from 9-14 months, to just days or weeks by avoiding the need to consolidate (or split) networks, to deal with network address translation (NAT) for overlapping IPs, or to stand up a VDI infrastructure.

VDI alternative.

Avoid the high costs, scalability issues, and latency of traditional VDI by replacing complex virtual environments with ZTNA. ZTNA delivers secure, seamless remote access through direct, policy-based connections to applications – based on user identity, device posture and context.
