Practical guides on firewalls, servers, networking and security — written from real installations, not from product brochures.

Practical guides from the field

Firewalls, virtualisation, servers, networking and camera systems — written from installations we actually did.

Fortinet

Choosing a FortiGate model: 40F, 60F, 90G or 100F?

The model number goes up and so does the price. But which one does your office actually need?

Fortinet

FortiGate licences explained: UTM, ATP and Enterprise

The appliance is a one-off purchase. The subscription is not — and what happens when it lapses surprises people.

SSL inspection on FortiGate: why it matters and how to deploy it

If you are not inspecting encrypted traffic, you are inspecting almost nothing. Here is what it takes to do it properly.

Fortinet

End internet outages: dual WAN with FortiGate SD-WAN

A second line only helps if the switchover is automatic and fast. Otherwise it is an expensive standby nobody remembers to use.

Fortinet

What is Fortinet Security Fabric, and what does it give a business?

One console instead of three, and a network map that is actually accurate. Here is what that is worth in practice.

Seven common mistakes in FortiGate deployments

We audit a lot of firewalls installed by other people. The same seven problems come up again and again.

Security

Ransomware has hit: what to do in the first 24 hours

The first hour determines how bad the next month is. What to do, in order.

Security

Backup for small businesses: the 3-2-1 rule

Most businesses have backups. Far fewer have a backup that survives ransomware — and that is a different thing.

Servers

What to check when buying a server

The decisions that hurt are rarely visible on the quotation. Here is what to look at before signing.

Servers

VMware ESXi or Hyper-V? A comparison

Both work. What decides it is licensing, what your backup product supports, and what your team already knows.

Servers

Windows Server upgrades: when and how

Running past end of support is not a technical preference — it is a compliance position, and usually not a defensible one.

Networking

Why is the office Wi-Fi slow? Six real causes

Buying better access points fixes it about a third of the time. Here is what the rest of the time looks like.

Networking

Do you really need managed switches?

Sometimes the honest answer is no. Here is how to tell which case you are in.

Cameras

Choosing security cameras for a workplace

Footage that shows an incident happened but not who did it is worth nothing. Specify against what the recording must prove.

Security

Guest Wi-Fi log retention in Türkiye: who must comply?

If you offer Wi-Fi to guests in Türkiye, this obligation applies to you.

Security

The first hour after data loss: what to do and what not to

The data is usually still there. The real loss happens during recovery attempts.

Hardware

RAID has failed: read this before you rebuild

The biggest losses come not from the failure itself but from the rebuild that follows.

Servers

Windows Server: Standard or Datacenter?

The price gap looks large, but past a certain number of VMs Datacenter comes out cheaper.

Servers

Your Microsoft 365 data is not being backed up

This is the most common gap we find: assuming that because it is in the cloud, it is backed up.

Security

How ransomware actually gets into a business

Three doors. Closing all three does more than buying the most expensive product.

Hardware

Choosing a UPS: how many VA is enough?

The VA figure on the box does not tell you how many minutes your equipment will run.

Hardware

Small business: is a NAS enough, or do you need a server?

If you only need file sharing the answer differs from if you need to run applications.

Fortinet

Your FortiGate licence has expired: what happens now?

Nothing switches off and no alarm sounds. That is exactly what makes it dangerous.

Networking

Moving office: the IT checklist

The problem is rarely moving day. It is the internet line arriving late.
