Calix IT Infrastructure
Calix Improves Efficiency With Scalable IT Infrastructure
Calix’s IT Infrastructure and cyber security is crucial to its operation. After introducing new technology to the market, Calix saw significant growth. They knew they needed to scale, and fast, and they knew their older IT infrastructure wouldn’t cut it. With this in mind, Calix contacted Stanfield IT about streamlining their IT infrastructure.

What Calix needed
Client Goals
Calix wanted an IT foundation—and an IT partner—that could:
- Scale with rapid growth, without constant infrastructure issues
- Provide a team available 24/7, to support users and systems across time zones
- Own and manage IT risk, so cyber security, governance, and operational risk didn’t fall back on internal stakeholders
- Deliver a dedicated account manager who could manage IT on a daily, ongoing basis—handling priorities, coordinating work, and keeping initiatives moving
- Give access to the right IT resources on demand, from service desk support through to senior engineers and security expertise
- Improve security and protect operations across multiple regions
The Challenge
As Calix grew, they were held back by:
- Legacy systems that were complex and difficult to scale
- No cloud platform in place, limiting agility as the business expanded
- The need to retire outdated hardware without disruption to a globally operating organisation
- A growing footprint that required stronger cyber security controls and clearer risk ownership
- The practical reality of operating across regions: they needed 24/7 coverage and a single accountable partner to manage IT day-to-day
What Stanfield IT delivered
Stanfield IT implemented a practical, growth-ready approach focused on reducing complexity, improving resilience, and strengthening security—while providing clear accountability and ongoing management.
- Dedicated account management (day-to-day IT ownership)
Calix had a dedicated account manager who acted as their ongoing point of contact—managing priorities, coordinating work, and ensuring IT tasks didn’t stall. This created continuity and clear ownership across support, projects, and improvements. - 24/7 IT support with escalation pathways
We provided always-on coverage so Calix teams could operate across time zones with reduced downtime and faster issue resolution—backed by escalation to the right specialists when needed. - IT risk ownership + ongoing governance
We helped Calix reduce IT risk by taking ownership of security and operational risk management—through cyber security review, prioritised uplift initiatives, and ongoing oversight aligned to best-practice guidance (including Essential Eight measures referenced in the original case study). - Cloud migration to reduce infrastructure overhead
We simplified Calix’s environment by reducing on-prem hardware and moving systems to the cloud—making it easier to scale and easier to manage. - Microsoft 365 (Office 365) rollout for collaboration + consistency
We deployed Office 365 to support smoother collaboration and more consistent security controls across teams and locations. - Cyber security audit + uplift
We conducted a cyber security audit and implemented improvements designed to better protect Calix’s systems as the organisation grew.
Why it mattered
With IT risk owned, day-to-day management handled, and 24/7 coverage in place, Calix could focus on growth and operations—without needing internal teams to chase vendors, coordinate resources, or carry the security burden.
IT infrastructure that scales easily
That was our focus – reducing risks and costs. We have addressed that, plus we now have an IT infrastructure that scales easily. The result is an IT setup more suited to the needs of the business. In addition, it has enabled us to more easily expand into Europe.
