**Quick Tip: Protecting Your Data with Network Segmentation**

Is your IT provider doing everything possible to reduce your attack surface and secure your data, as well as your clients'?

One commonly overlooked strategy by IT providers is **network segmentation**. By segmenting your network into smaller VLANs that can't communicate with each other, you can significantly reduce the number of entry points attackers can exploit.

**What does this mean?**  

Essentially, systems like your phones, business devices, credit card processing, employee devices, security equipment, and guest WiFi are all exposed to the internet. Guest networks and employee devices are particularly vulnerable, and attackers can exploit weaknesses in your phone or camera systems without you realizing they’ve used those devices to infiltrate the rest of your network.

**How do you prevent this?**  

Ask your IT provider if your network is properly segmented. This involves creating isolated subnets for each category of devices and preventing communication between these subnets. For example, your phone system should be on its own subnet, your guest WiFi on another, employee devices on a separate one, and your business computers on their own.

Most modern business-class and even some home-grade network equipment support this feature. While it requires some initial configuration, it’s a cost-effective and behind-the-scenes way to reduce the attack surface and help protect your data.

There’s a lot more to this, and your IT provider can explain further or dive deeper into the technical aspects. But understanding network segmentation is a great first step in ensuring you’re getting the protection you deserve.

Does your IT provider try to reduce the attack surface as much as possible to secure your and your clients' data as much as possible.

One of the things that I think is often missed by IT providers is network segmentation.  Segmenting your network into smaller VLANS that cannot communicate with each other quickly, and affordably reduces the amount of vectors that an attacker can use to compromise your and your customers' data.

What does this mean?  Essentially, your phone system, your business devices, credit card processing, your employee devices, security devices and your guest WiFi network all face the internet.   Your guest network, and your employee devices are out of your control and your phone and camera systems are vulnerable to an attack and you will never see an attacker using those devices to pivot on your network.

How do you prevent this from happening?

Ask your IT provider if your network is properly segmented and isolated.     What this is is creating isolated subnetworks (subnets) for each category of device, and then preventing communication from one of those subnets to another.  Your phone system has its own subnet.  The guest network is its own subnet and SSID (WiFi network).  Your employee's devices are on their own isolated subnet, and your business computers are on their own as well.   

Most modern business class network equipment and some home network equipment allows for this.  It does take a little bit of time to configure, and implement but should require minimal investment. This is a behind the scenes way of reducing the attack surface and helping to protect you and your clients' data without much effort or cost.

There is a lot more to this but your IT provider can explain or we could go into a deep dive later. but hopefully this can at least help start the understanding of things that you should expect from your IT provider.
