What are you protecting?
Network Security South Africa is the part of the network that decides what is allowed to talk to what. A firewall at the edge, separated segments inside, remote access that does not open the whole network, and someone watching the logs.

Get the Best QuoteWhat Gets Put In Place
- A firewall. At the edge, with rules written down rather than accumulated.
- Segmentation. Cameras, guests, payments and staff kept apart from each other.
- Remote access. A VPN per user rather than a port opened to the internet.
- Patching. Firmware on the firewall, switches and access points kept current.
- Monitoring. Alerts on the things that matter, not a log nobody reads.
- Backups you can restore. Tested, and kept where ransomware cannot reach them.
The Weak Points Found Most Often
- Default passwords. On switches, cameras, recorders and access points.
- Flat networks. A compromised camera sitting on the same network as the accounts PC.
- Open remote desktop. Exposed to the internet so someone can work from home.
- Unsupported firmware. Equipment years past its last security update.
- Untested backups. A backup job that has been failing quietly for months.

Get the Best QuoteWhat Affects the Price
- Number of sites. Each branch needs its own device and its own tunnel.
- Number of users. Firewall licensing is commonly sized by users or throughput.
- Line speed. A firewall must be sized to inspect traffic at your line speed.
- Licence tier. Content filtering and threat protection are add-ons, not included.
- Compliance. A regulated environment needs documentation and evidence.
- Support level. Business hours against twenty-four hour response changes the monthly fee.
What to Include in Your Request
- How many users and sites. And whether branches connect to each other.
- Your internet line speed. It decides the size of the firewall.
- What is on the network. Cameras, point of sale, servers, guest WiFi.
- Remote working. How many people, and what they need to reach.
- What you have now. The current router or firewall, and its age.
- Any requirement driving this. An insurer, a client questionnaire or an incident.
Before You Buy a Firewall
- Change the default passwords first. It costs nothing and closes the commonest door.
- Separate the cameras. They are the devices most often reached from outside.
- Test a restore, not a backup. A backup nobody has restored is an assumption.
- Ask what the licence covers. The device without its subscription is just a router.
- Write the rules down. An undocumented firewall becomes unmaintainable within a year.
Network Security FAQs
Is the router from my internet provider enough?
For a home, often. For a business with staff, servers, cameras and remote access, it has neither the segmentation nor the logging to do the job, and it is rarely updated.
What does segmentation actually achieve?
It stops one compromised device reaching everything else. A camera or a guest laptop on its own segment cannot see the server, which is what limits the damage.
Do I need twenty-four hour monitoring?
It depends on what an hour of downtime costs you. Many small businesses start with a well-configured firewall, tested backups and business-hours support, and add monitoring later.
How often should firmware be updated?
Firewalls and anything reachable from the internet as soon as updates are released. Switches and access points on a scheduled basis, usually quarterly.
Network security is one of the jobs providers on Network Cabling South Africa quote for, alongside audits, access control and cabling.
