Fyrfly Systems was founded by practitioners who spent over a decade building security and sensor technology at an international level. We apply that depth exclusively to schools and the public sector, because that is where it is needed most and used least.
Most security installers treat schools and councils as commercial clients with different branding. The same design templates, the same equipment, the same approach. Compliance language gets added to proposals but rarely shapes the actual specification. When something goes wrong post-installation, the paper trail turns out to be thin.
Fyrfly was founded on a different premise. Schools carry real safeguarding obligations under KCSiE. Public buildings are subject to Martyn's Law. NHS estates handle data and access with accountability that commercial buildings simply do not face. These are not edge cases — they are the core design criteria.
That means building systems that satisfy the Designated Safeguarding Lead as well as the estates manager. Writing documentation that the Responsible Person can hand to their governors. Designing access control that accounts for fire safety, lone working and visitor management simultaneously, not as separate afterthoughts.
We exist because that combination of technical depth and sector knowledge is rare, and the organisations that need it most are the ones with the least resource to go searching for it.
Every decision we make is filtered through a single question: would a governor, a headteacher, or a procurement officer be comfortable explaining this choice? If the answer is no, we do not do it.
In 2011, Simon co-founded Sunstone Systems from nothing. No clients, no infrastructure, no template to follow. Over thirteen years, the team built a globally recognised platform for solar-powered surveillance, autonomous power systems and IoT telecommunications, deploying in some of the most demanding environments in the world.
The client list was not domestic. Chevron, Rivian Automotive, Intel, Network Rail, Tengizchevroil in Kazakhstan. The technical environments were not forgiving. Extreme temperatures, remote sites, critical infrastructure with zero tolerance for failure. Three patents were granted along the way: mmWave radar, acoustic AI, and IoT architecture. In 2023, Sunstone was named in the IFSEC Global Top 50 — one of the most-watched annual lists in the international security industry. In 2024, the business was acquired.
Fyrfly is the application of everything learned building technology at scale, directed at a sector where the stakes are genuinely high and the quality bar has historically been low. Schools that are not physically secure are not safe. Public buildings that cannot demonstrate compliance are exposed. The technical capability to fix both of those things exists. Bringing it to the organisations that need it is the point.
Simon also holds Chartered Marketer status with the Chartered Institute of Marketing. That is an unusual credential for a security founder, but it reflects something important: the gap between what Fyrfly installs and what a governor or procurement officer understands about it matters. Communication is part of the service.
We have built large-scale technology projects in environments where failure has real consequences. That shapes how we approach every project, regardless of scale. Fixed scope, fixed price, documented changes, honest timelines. The people who survey your site are the people accountable for your installation.
We do not use a sub-contractor chain that dilutes accountability at every step. We do not win work by underquoting and recovering costs through variations. We do not cold-sell to your staff during maintenance visits. These are not marketing claims — they are the standard we hold ourselves to because we have seen what happens when security companies do not.
Every organisation we work with operates under a framework of obligations: to their governors, to the DfE, to the ICO, to the Security Industry Authority. Those obligations do not disappear once the installation is signed off.
We design systems that satisfy those obligations on day one and continue to do so over the life of the installation. That requires understanding the legislation, not just referencing it in a proposal.
