Zero Trust: The Next Step Beyond VPN

Corporate IT security is changing rapidly as cloud adoption, remote work, and hybrid environments dissolve the traditional perimeter. VPNs can no longer keep up, bringing complexity, weak user experience, and growing risks.

The answer is Zero Trust Network Access (ZTNA) from HPE Aruba—a scalable, cloud-based approach built on the principle that no one is trusted until verified, and access is granted only to approved resources.

Why Traditional VPNs Fall Short

VPNs were critical during the remote work boom, but they expose entire networks once a user logs in. This creates major vulnerabilities and requires complex policies to limit damage. Breaches have multiplied, performance is inconsistent, and the user experience is poor — all signs VPNs are no longer fit for today’s environment.

The Core of Zero Trust Security

Zero Trust Network Access (ZTNA) flips the VPN model. Instead of granting full network entry, users only reach the specific apps or data they’re cleared for, through secure portals with multi-factor authentication. Every access is rule-driven, visible, and tightly controlled.

HPE Aruba’s Approach to ZTNA

HPE Aruba’s ZTNA delivers more than access control, adding:

• One client for all devices, always selecting the fastest cloud route.
• Browser-based entry for external partners without software.
• Secure Web Gateway to enforce browsing policies.
• CASB to block risky cloud uploads.
• Sandbox analysis for suspicious files.
• Monitoring to track user experience in real time.

Stronger Together: ZTNA and SD-WAN

When combined with SD-WAN, ZTNA applies consistent security to all traffic, even from IoT devices. It also reduces costs by replacing leased lines with optimized internet connections, while keeping performance stable. Large-scale rollouts can be completed quickly, even with small IT teams.

ClearPass for Multi-Vendor Environments

HPE Aruba’s ClearPass supports over 100 vendors, ensuring Zero Trust access across diverse IT setups. This interoperability allows consistent security and visibility even in complex, mixed environments.

Why Zero Trust Matters Now

Enterprises worldwide are moving away from VPNs as their weaknesses become clear. ZTNA provides granular control, stronger security, better performance, and easier management. For organizations aiming to stay resilient in a cloud-first, hybrid world, Zero Trust is no longer optional—it’s essential.
