About ZNZ Preventive Technologies
As security demands intensify across borders, government institutions, and law enforcement, precision and reliability have never been more critical. For over three decades, ZNZ has delivered both.
Founded in 1991, the family-owned business specialises in high-end security systems. They represent world-class brands such as Smiths Detection, CEIA, and Scanna MSC, and serve clients including the Hungarian Police, the Ministry of Interior, major banks, courts, and Budapest Airport.
Beyond supplying equipment, ZNZ delivers complete, end-to-end service, from system design and installation to maintenance, repairs, and continuous post-sale support. But as machines and systems grow more advanced, the team is increasingly challenged to meet evolving industry standards.
The challenge: Managing complex service operations in a fast-moving environment
ZNZ’s service division operates around the clock, every day of the year. Meeting strict SLAs — sometimes requiring a technician on-site within four hours — is essential when supporting high-security clients such as government agencies and major transport hubs.
But as the demands grew, the company’s internal tools failed to match that same level of efficiency. For years, the team depended on Excel sheets and outdated systems to manage customer requests, maintenance schedules, and service reports. Over time, the drawbacks of this setup became clear:
- Service history and past solutions were often lost or inaccessible.
- Handwritten field reports were hard to read and difficult to digitise later on.
- It was nearly impossible to analyse performance or spot recurring technical issues.
- Administrative work required disproportionate effort. Technicians had to report manually, while the back office had to spend hours consolidating data.
As security equipment became more sophisticated and required increasingly complex maintenance and repairs, ZNZ’s need for a structured, digital knowledge base became urgent.
The team wanted a system that could help technicians log issues, track fixes, and retain knowledge over time to ensure that valuable expertise wouldn’t disappear when people moved on.
The solution: From spreadsheets to a smart, scalable field service system
ZNZ first began working with VisualLabs in 2020, exploring how to modernise their service management. After a pandemic-imposed slowdown, collaboration resumed in 2022 with a clear goal: implement a centralised, digital field service solution that could support ZNZ’s operations long-term.
Together, they built a custom Dynamics 365 Field Service system, connected with Power Apps and Microsoft Teams, designed around ZNZ’s real-world workflows.
Key capabilities included:
- Digitalising service requests and maintenance logs, replacing Excel and manual forms.
- Automating work order assignment across the service team, optimising field response times.
- Creating a knowledge base that stores past solutions, making troubleshooting faster and more consistent.
- Supporting remote collaboration, allowing back-office and field teams to stay aligned without being in the same location.
- Improving contract and SLA tracking, ensuring all maintenance commitments are fulfilled and invoiced accurately.
Over time, ZNZ’s internal team felt the need to take a more active role in managing the system. With guidance from VisualLabs, they learned to configure and extend the platform themselves, even without prior programming experience.
As Oliver Pammer-Zagroczky recalls:
“VisualLabs didn’t just implement a system; they helped us understand it. We can now customise workflows on our own, automate tasks, and continuously adapt the platform to our needs.”
The results: Faster processes, fewer errors, and a foundation for future growth
Since going live, ZNZ has seen measurable progress across its service operations:
- Administrative effort has decreased significantly, freeing time for higher-value work.
- Maintenance data is centralised and accessible, reducing the risk of duplicated or lost information.
- SLA performance has strengthened, evidenced by reduced dispatch time and enhanced reporting accuracy.
- Field technicians have real-time access to all relevant details from any device, improving communication and customer experience.
While the system is still being refined, its impact is already clear. Field personnel can access and share insights faster and with greater transparency, and the company has a solid foundation to keep up with the accelerating pace of the defence and security sector.
As Oliver notes:
“As the world speeds up, our customers expect faster, more reliable service. With this system, we will be able to keep pace and set ourselves up to scale with confidence.”
Building a fully connected service ecosystem for the future
Encouraged by the success of the Field Service implementation, ZNZ is now exploring the next steps in their collaboration with VisualLabs.
Planned developments include:
- A customer portal that allows major clients to log service requests directly.
- Integration of machine and service history analytics, helping predict and prevent failures.
- Using IoT data to trigger proactive maintenance based on real-time equipment performance.
With these initiatives, ZNZ is moving from responsive service to a predictive, data-driven approach, preserving its legacy of reliability through a new generation of precise, technology-enabled solutions.
