Who are SIACO?

People often ask where the name came from. Apart from wanting  something unusual, different and memorable, it had to mean something.

SIACO stands for Security Industry Associates Consulting.

​

​​When I founded SIACO the vision was to bring together the best people, expertise and experience to provide independent and intelligent security consultancy services.

​

Today, SIACO helps organisations and service providers achieve greater    value from their security services and demonstrate the value they deliver.

​

We challenge assumptions, analyse performance and provide independent advice, combining security expertise with commercial acumen to improve effectiveness and maximise value from security investments.​ In turn, our clients are better able to protect their people, assets and interests.
