Wilson Ferreira interviewed by Valor Magazine
On 15 October 2026, Valor Magazine published an interview with Wilson Ferreira, founder and manager of WF Sistemas de Segurança. Under the title "Growing with rigour in a changing sector", the article shows how WF has achieved steady growth in a sector where technology, prevention and technical know-how matter more every year. It is recognition we share with the whole team and with the clients who trust us.
From one person to a team of nine
WF was founded in June 2018 and, by the end of that year, it was a one-person company. Today we are a team of nine. We have grown at the pace of our work and of our clients' trust, and we want to keep it that way: step by step, both in our technical team and in our client base.
Every project starts on site
There are no one-size-fits-all solutions, because no two sites and no two clients are the same. Before we propose a system, we assess the site, identify the risks and find out who will use it day to day: an advanced system loses its value if the user cannot manage it. This close relationship explains another feature of WF, which has no salespeople in the traditional sense. "Very often, our clients end up taking on that role themselves," says Wilson Ferreira.
Preventing before the risk
The way people think about security is changing, especially at home: concern no longer arises only after an incident. Alarms, video surveillance and other systems now work together and are easier to use. Even so, no system removes risk completely. What it does is reduce it and act as a strong deterrent.
“More and more people are looking to protect their homes before they have high-value belongings inside.”
Tested before it reaches the client
Keeping up with innovation does not mean accepting everything that comes onto the market. WF has its own technical area where equipment is tested in real conditions before it is proposed, to confirm its reliability, its features and how well it fits each need. "Personally, I like to know the equipment very well before I propose it to a client," Wilson Ferreira stresses. Not everything the major manufacturers release makes sense for the Portuguese market, and that is our job: to test, assess and choose what does.
Technicians trained in the field
Finding specialised technicians is a challenge for the whole sector, because there is no academic training aimed at electronic security systems. At WF, the answer is hands-on training: newcomers work alongside experienced technicians, learn the equipment in the field and complement that experience with specific training. It is a demanding process, but an essential one when what is at stake goes beyond material assets.
People make the company
For Wilson Ferreira, what makes a company grow is its people: "The growth of a company is never the work of a single person." This interview therefore belongs to the whole WF team and to every client who recommends us.
