Zero Trust Security Meets AR in Surespan’s Remote Operations
In today’s distributed, high-risk work environments, Zero Trust Security is no longer optional. For Surespan, a UK-based manufacturer of access and safety solutions, this reality became evident as its technicians increasingly relied on digital tools in challenging field conditions—from rooftops to remote industrial sites.
These environments demanded secure, real-time access to critical data and expert support, often over unreliable networks. Traditional VPNs proved inadequate. In response, Surespan adopted a cutting-edge solution: combining Zero Trust Security with Augmented Reality (AR) to enhance remote operations.
The result? A streamlined, secure digital workflow that empowers technicians and protects sensitive systems at every access point.
Why Traditional VPNs Fell Short
Surespan technicians accessed blueprints, site reports, and internal platforms using a mix of devices—many of them unmanaged. VPN reliance introduced three major problems:
- Over-permissioned access: VPNs granted broad network access, with no granular controls.
- Device risks: There were no checks for device health or security posture, increasing vulnerability.
- Poor performance: VPN connections were often slow, making large file transfers and live support difficult.
As Surespan expanded globally, these limitations exposed operational and security risks, necessitating a more modern, adaptable approach.
What Is Zero Trust Security?
Zero Trust security operates on a simple but powerful principle: never trust, always verify. Rather than assuming anything inside the network is safe, it continuously validates access based on identity, device status, and context.
With Zero Trust, access is granted only when user identity, device integrity, and risk level meet all criteria. If anything appears suspicious, access is denied or limited. Network segmentation also ensures that even if one area is breached, others remain protected.
Surespan adopted a Zero Trust Network Access (ZTNA) approach. Replacing VPNs, they implemented a secure gateway that checks identity, device health, and location before granting access. Every session is logged and monitored, providing real-time visibility across the network.
Using AR to Revolutionize Field Support
In parallel, Surespan introduced AR into field operations. Technicians used AR glasses or tablets to receive live guidance from engineers back at headquarters. Through real-time video streaming, experts could overlay diagrams or instructions directly onto the technician’s view.
This drastically improved support. Technicians no longer had to describe issues over calls or wait for senior staff to travel onsite. Everything became visual, instant, and more precise.
However, these AR devices, often connected via unsecured networks, introduced new risks. Without proper security, they could easily become entry points for cyberattacks.
Integrating AR and Zero Trust Into One Workflow
Rather than managing AR and security separately, Surespan merged them into a single secure workflow. Here's how a typical AR-assisted operation is secured:
| Step | Action | Security Layer |
|---|---|---|
| 1 | Technician arrives with AR device | Device identity verification |
| 2 | User authentication begins | Multi-factor authentication |
| 3 | Device scanned for OS updates and threats | Compliance enforcement |
| 4 | Access to needed files granted | Role-based access control |
| 5 | Remote engineer joins AR session | Session encryption and monitoring |
This end-to-end model enables technicians to work quickly and securely, without exposing the wider system to threats.
Measurable Benefits
The shift to Zero Trust and AR brought immediate improvements:
- Fewer security incidents: Unauthorized access attempts dropped significantly within three months.
- Faster issue resolution: Diagnostics that once took hours were resolved in minutes using AR.
- Reduced travel costs: AR-powered remote support helped avoid in-person visits, saving over $54,000 in travel expenses.
- Higher field confidence: Technicians felt more supported with real-time expert input and fewer technical disruptions.
Key Takeaways for Other Organizations
Surespan’s transformation offers practical lessons:
- Address real pain points: Technology was chosen to fix slow support, weak security, and poor field experience—not just for hype.
- Embed security into workflows: From device boot-up to data upload, security was integrated, not bolted on.
- Prioritize the user experience: Tools and training focused on empowering frontline teams.
- Make identity the foundation: Consistent, secure access was maintained regardless of device or location.
What’s Next for Surespan?
Building on this success, Surespan plans to expand AR use into its factory environments for inspections, maintenance, and staff training. Simultaneously, the company is exploring AI-powered automation to support decision-making within its Zero Trust framework, ensuring proactive and scalable security.
Distilled
Surespan proves that security and innovation don’t have to conflict. By integrating Zero Trust security with Augmented Reality, the company built a remote operations model that is both resilient and efficient. For any organization managing field teams, this approach shows how the right combination of tech and strategy can turn remote work into a competitive edge.
