About Fyrfly Systems

Not generalists who work in education and the public sector.
Specialists built for it.

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.

Why Fyrfly Exists

The security industry has a public sector problem

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.

The Founder

Thirteen years building the technology. Now applying it where it matters.

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.

2011
Co-founded Sunstone Systems
Started from a blank sheet of paper. No revenue, no team, no precedent. Built the initial solar surveillance platform and first commercial deployments.
2011 to 2024
Global deployments and platform development
Systems deployed for Chevron, Rivian, Intel, Telent and Network Rail. Three patents granted. IFSEC Global Top 50 recognised. Platform expanded to autonomous power and IoT telecoms.
2024
Sunstone Systems acquired
After thirteen years, the platform and business were acquired. The technology and methodology built over that period became the foundation for what came next.
2026
Founded Fyrfly Systems
Applied thirteen years of sensor platform, AI analytics and IoT architecture experience to the UK education and public sector — a market chronically underserved by the mainstream security industry.

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.

What We Are

Three things that define how we work

Sector-only focus
We work exclusively with education and public sector clients. Not as a ring-fenced division of a generalist company, but as an organisation built entirely around that environment. Our design standards, compliance knowledge and documentation are built for your context, not adapted from a commercial template.
Technical depth, not just installation
There is a significant difference between fitting a camera and designing a security system. Our background is in sensor platform development, AI analytics and IoT architecture. That depth changes how we specify equipment, how we design coverage, and how we configure AI-assisted detection. It is the difference between a system that works and one that simply exists.
Documentation that holds up
Every installation produces a complete paper trail: design drawings, commissioning records, as-built documentation, handover packs, operator training, and maintenance logs. We produce documentation to the standard that governors, procurement officers, and the Security Industry Authority will expect to see. Because what you cannot evidence did not happen.
How We Work

Straightforward. Documented. No surprises.

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.

01
Fixed price, written scopeScope, price and timeline are agreed before any work begins. Variations are documented and approved before they become costs. You will not receive an unexpected invoice.
02
One team, clear accountabilityThe engineers who survey your site are the people responsible for your installation. Accountability stays in one place from survey to sign-off.
03
Compliance built in, not bolted onDfE, KCSiE, Martyn's Law and UK GDPR requirements are part of the design specification, not a section added to the proposal to help it win.
04
Handover that transfers knowledgeStaff training is included as standard. When we leave a site, your team understands how to operate what we have installed and what to do when something needs attention.
05
Direct access to decision-makersOur clients deal directly with the people who hold technical and commercial accountability for their project. Not account managers, not call centres.
06
Systems we are prepared to maintainWe design and install systems we will support for ten years. That changes every decision we make about equipment, documentation and configuration.
Standards and Compliance
BS EN Standards
All installations designed and commissioned to the relevant British and European Standards: BS EN 62676 (CCTV), BS EN 50131 (intruder alarms), BS 5839 (fire detection), BS 8243 (access control). Standards are the floor, not the ceiling.
DfE Protective Security and Preparedness Guidance
Design methodology follows the Department for Education's guidance on school security. Camera placement, access control zoning, visitor management and lockdown procedures are all specified with DfE guidance as the primary reference.
KCSiE (Keeping Children Safe in Education)
Security systems in schools must support the DSL's safeguarding obligations. Our designs account for unsupervised areas, visitor identity management, access restriction and the audit trail requirements that KCSiE demands.
Martyn's Law (Terrorism (Protection of Premises) Act 2025)
We produce a site-specific Martyn's Law compliance document as part of every installation. Enforcement begins April 2027. Every school and public venue with a capacity of 100 or more is in scope. We are ready for this.
UK GDPR and Data Protection Act 2018
CCTV processing personal data requires a lawful basis, a DPIA, a retention policy, access controls and a Subject Access Request workflow. We provide all of these as standard, not as a consultancy add-on.

The standards that govern your building are the standards we design to.

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.
