Make access control secure
We assess the badges, readers and locking systems in gyms and residential buildings, then move them to technology that still holds up today.
Network · IT · Cybersecurity
Secure networks. Access you control.
We plan, secure and document networks and access control systems for businesses in Zurich and the surrounding area. And we bring order to the IT at home. Explained clearly, implemented properly, without the jargon.
We reply within 24 hours.
Services
Three problems we solve
Business or home, it comes down to the same question. Who gets into your network and your building, and who does not.
Networks and firewalls
Routers, firewalls, switches and Wi-Fi set up properly: segmentation, secure configuration, guest traffic kept away from the business network.
IT help at home
Install and configure a home network, router or firewall, fix Wi-Fi that never quite works, set up devices securely. On site, at your place.
Focus area
Your badge system may be older than it looks.
Many gyms and residential buildings still run on MIFARE Classic cards. That card technology has been considered broken for years. It can be cloned in minutes with hardware anyone can buy, with no special skills required.
We look at what is actually installed, explain the risk in plain language and guide you to a system that still holds up, without being tied to any manufacturer.
- Inventory: card type, readers, controllers
- Risk assessment without the jargon
- Migration path with cost and time frame
- Support comparing quotes and during rollout
- Vendor-neutral, we do not sell hardware
How it works
Working together
No surprises. You know what will be done and what it costs before it starts.
First conversation
Free and without obligation, by phone or on site. You describe the situation, we tell you honestly whether and how we can help.
Assessment and quote
We review the current state and send you a written quote, either a fixed price or a clearly estimated effort.
Delivery and handover
Implementation within the agreed scope, followed by documentation you can actually read. You stay independent, including from us.
About us
Specialised, not a general store
Networks, access and security. That is where we stay.
Serrano NetSec specialises in secure network infrastructure and access control. We advise on a vendor-neutral basis, do not sell hardware ourselves and take no commission from suppliers. What we recommend therefore depends on your situation alone.
