Perimeter assessment
Every public IP, domain and subdomain is checked for listening services: abandoned test machines, management consoles, legacy FTP. Each one is shut, locked down or given a documented reason to stay.
Ransomware crews rarely need sophisticated tricks. Many simply walk through an opening that has existed for years: remote desktop published straight to the internet, a VPN box missing its patches, a camera recorder still using the password printed in its manual. Once in, they typically land on one undivided network where finance PCs, factory controllers, the visitor Wi-Fi and the servers all talk freely. Think of a distribution warehouse near Koper where scanners, the stock system, office PCs and cameras all sit on one subnet and the software supplier reaches the WMS server via an open NAT rule. A single weak spot can stop every shipment. Our infrastructure work cuts those links. We start by examining everything you expose externally, as an intruder would. Next the network is divided by purpose, traffic between zones is restricted to what is necessary, and access from outside is moved to authenticated channels that keep a record. No new boxes and no site visits are needed.
We configure firewalls and switches that the manufacturer still patches. Replacement is suggested only for models out of support; your own people or a local supplier fit the unit, and we take care of the setup online.
Every public IP, domain and subdomain is checked for listening services: abandoned test machines, management consoles, legacy FTP. Each one is shut, locked down or given a documented reason to stay.
Years of “just for now” entries, forwarded ports of unknown origin and allow-everything lines are reviewed. Anything kept is labelled with its purpose and the person answerable for it.
Separate VLANs are created for desks, shop-floor or stock equipment, servers, cameras, printers and visitors. Cross-zone traffic is permitted only where a real need exists, and only on specific ports.
Published RDP and forwarded ports disappear, replaced by VPN with a second sign-in factor or by identity-aware access. Vendor sessions become individual, time-boxed and recorded.
Enterprise authentication with WPA2 or WPA3 for employees, or at minimum strong, regularly rotated keys; isolated clients and capped bandwidth for visitors. Busy spaces such as a hotel lobby or surgery waiting area get their own design.
Management pages of network and CCTV equipment can be reached only from a dedicated admin network. Factory passwords are replaced and idle services turned off.
Altering a network can interrupt business, so the work is staged and every stage can be reversed.
Current diagram, equipment list and an outside-in scan. Where no diagram exists we build one online, and cable tracing is done by your colleague with us watching on video.
A clear matrix of permitted zone-to-zone traffic and ports. After your sign-off, the sequence and change windows are fixed.
Riskiest gaps get shut on day one; zones then move across in turn. Configurations are saved beforehand and changes are made out of hours.
We rescan from outside, test cross-zone access and deliver a current diagram, rule register and list of administrative access.
In a single undivided network, one infected laptop can take the entire company with it. Zoning does not keep intruders out, but it slows their movement, makes them easier to notice and limits what they can reach. Keeping office ransomware away from the factory floor or the warehouse is frequently what separates a bad afternoon from a week-long shutdown.
Yes. Controller and machine PC settings remain as they are; we only isolate their network and filter what reaches it. If the equipment maker services machines remotely, that connection gets its own logged route. Cut-over happens between shifts or during planned downtime.
A personal VPN account with two-step verification, or a remote session that expires automatically, limited to the one server and port the vendor needs. The forwarded port is then closed, with timing agreed directly with the vendor.
Generally yes, provided the maker still releases security fixes and the unit handles your throughput. Hardware past its support date is a hazard because it can no longer be patched, and our mapping report will say so.
For configuration, completely. Where hands are needed, for instance to move a patch lead, someone on your side does it while we watch on video. Changes are sequenced so a mistake can never cut off our management access.
Tell us how many locations you run, what firewall protects them and which people connect in from elsewhere. We will propose an initial perimeter check.
Enquiry received
An engineer will write back no later than the following working day. Faults that leave your staff unable to work are always looked at first.
No town by that name here. Check the letters, or settle for the nearest larger place. Our engineers work only over the internet, so Kočevje and Koper get precisely the same treatment.
