Customer Story
Plieger is known as a wholesaler that goes beyond simply delivering: this organization also goes the extra mile when it comes to digital security. John Smits, security system administrator at Plieger, explains why the company chose Tesorion’s managed firewall services.
Data and continuity: the foundation of our services
“Our services revolve around reliable delivery and completely unburdening installers,” John explains. “In doing so, we are highly dependent on the availability of data and connections, something you might not immediately expect from us. Our customers can place orders in many different ways: via the Express branch, webshop, by phone, by email, or directly in one of our showrooms. That makes stable data connections crucial to our services.”
Firewalls as the hub of the network
To guarantee that reliability, firewalls are essential. They connect branches, provide VPN connections with suppliers and the parent company, and filter all data traffic. “Quite simply,” John says, “without a firewall we have no internet and therefore no services. That is why it always has to work. Tesorion’s managed firewall services fit in perfectly with that.”
A partnership that works
Plieger’s ICT department manages the firewalls partly itself, but can always rely on Tesorion’s experts. Short communication lines, quick follow up, and objective advice characterize the collaboration. “Problems are addressed immediately and they understand our business. Updates cannot be done during working hours or in the evening, because orders must continue. The fact that this can then be done on Sunday morning is no problem at all for Tesorion.”
Finding the best solution together
When a scenario arose in which the firewall had to be replaced, Plieger was presented with several options. “Together with the account manager, we looked at functionality, necessary requirements, and costs. They genuinely searched for the best solution for us, not simply the most expensive or easiest option. That is how, for this scenario, we ended up with a redundant firewall.”
Security tailored to our needs
The availability of internet connections is crucial to Plieger’s processes. That is why, with every firewall configuration, careful consideration is given to what access is needed and what risks are involved. “We set this up very specifically so that processes continue to run. At the same time, it is reassuring to know that Tesorion’s experts are always looking along with us.”
