When you’re a structural engineering firm working across multiple locations, IT isn’t just a support function, it’s a major artery of your business.
For Sullivan Hall, a small to medium sized engineering consultancy with offices in Auckland, Tauranga, and Queenstown, seamless access to information is critical. Their teams collaborate across regions, sharing high volumes of documentation, including Microsoft Office files and multiple industry-specific drawings and engineering detail data. In addition to multiple in-office activities, members of the engineering team are frequently on-site, meaning systems must be reliable, accessible, and secure from anywhere.
The Challenge
Prior to working closely with Marksmen IT, Sullivan Hall felt confident in their IT setup. Their incumbent external IT service provider managed service requests and basic software licensing effectively, and operations were running smoothly.
However, two key events created a turning point:

- The upcoming expiration of the licensing of the existing endpoint protection solution, with a desire to investigate alternative options for a replacement platform
- Their existing IT provider announced a change in business model, reducing their ability to deliver the level of service required
The Start
Although a number of the potential solutions met the technical requirements, a key element of the final selection was significantly influenced by Marksmen IT’s support during the trialling process. Marksmen IT’s desire to not simply sell a product, but to understand Sullivan Hall’s business and the forward vision of the organisation, ensured a fully-informed decision could be made.
The review of candidates for the replacement endpoint protection solution led to Sullivan Hall’s initial engagement with Marksmen IT.
The Approach
Marksmen IT initially entered the picture as a vendor supporting endpoint protection, but their role quickly expanded.
As Sullivan Hall became aware of the broader portfolio of service offerings from Marksmen IT, the breadth of engagement grew.

Marksmen IT took a pragmatic, structured approach across a number of significant IT projects:
- Planning and deployment of infrastructure to support a new project management system
- Transition planning for end-of-life Cisco networking and Dell server hardware
- An independent review of a separately commissioned cybersecurity audit; collaborating to develop clear, prioritised actions
The Outcome
What began as a single-solution engagement has evolved into a long-term partnership.
Marksmen IT is now embedded as a trusted advisor, helping Sullivan Hall make informed IT decisions while maintaining operational continuity across all locations.
As Sullivan Hall’s IT consultant puts it:
“I instantly felt comfortable working with Zoltan… You get what you see. He’s pragmatic, almost self-effacing. His technical expertise is fantastic.”
“I can’t recommend him enough. He’s knowledgeable, capable and able to match the needs of an organisation.”
The Difference
For Sullivan Hall, the value isn’t just technical capability, it is the ability to translate complexity into clarity, and to deliver solutions that fit the way their business actually works.
