Home/Home Firewall

Residential protection

A firewall for the whole house, not just the laptop.

Cloud-managed protection for your Wi-Fi network, your router and every device connected to them — including the ones that have no security settings of their own.

How SecureSonic protects a home networkTraffic arrives from the internet, passes through the SecureSonic cloud firewall where it is inspected and unwanted traffic is blocked, then reaches the Wi-Fi router and the connected devices on the home network: laptop, phone, TV, camera and smart-home devices.InternetINBOUND + OUTBOUNDBLOCKEDSecureSonic Cloud FirewallPOLICY · INSPECTION · MONITORINGALLOWLOGBLOCKCLOUD-MANAGED · NO EXTRA SOFTWARE ON DEVICESCLEAN TRAFFICWi-Fi routerHOME GATEWAYLAPTOPPHONETVCAMERASMART HOMEPROTECTED CONNECTED DEVICES

How it works

Traffic is checked before it reaches anything you own.

Everything your household does online crosses one boundary. That boundary is where a firewall belongs.

Traffic arrives

Requests, streams, updates and unsolicited connection attempts all head towards your network from the internet.

Policy is applied

Each connection is evaluated against the rules set for your service — allowed, limited or blocked.

Your devices see only what passed

Clean traffic continues to your router and on to your devices. The rest stopped at the boundary.

Router and gateway

Your router faces the internet all day. Give it backup.

The gateway is the one device on your network with a permanent public-facing connection. Default settings and forgotten remote-management options are a common weak point, and most people have no reason to think about either.

  • Controls around administrative and remote management access
  • Filtering of inbound connection attempts nobody asked for
  • Visibility of what the gateway is actually passing
  • Separation between main, guest and device networks where supported

Wi-Fi and guest access

One connection, sensibly divided.

A visitor's phone, a smart doorbell and the computer holding your family photos do not belong in the same trust zone. Separating them limits how far a problem on one device can travel.

Where your equipment supports it, guests and smart devices can reach the internet without reaching the rest of your network. Available separation depends on your router and service configuration.

Connected devices

Covers the things you'd never think to secure.

Smart speakers, cameras, TVs, printers, plugs, thermostats and appliances all connect out to the internet, often continuously, and most offer nothing you could call a security setting.

Because protection is applied to the network they share, they are covered by being connected — there is no app to install on a device that barely has a screen.

Coverage

Inside the network and out.

A home firewall is not only about keeping things out. It also pays attention to what leaves, and to how devices behave with each other.

Inside

Internal network activity

Traffic between devices inside your home. Policy defines which zones can reach which, so a compromised device has fewer places to go and unusual internal behaviour becomes visible.

Internal network zonesA firewall policy sits above three network zones: a main network with full access, a smart device zone with limited access, and an isolated guest zone. Traffic between zones follows the configured policy.MAIN NETWORKFULL ACCESSSMART DEVICESLIMITED ACCESSGUEST ACCESSISOLATEDFirewall policyTRAFFIC BETWEEN ZONES FOLLOWS THE POLICY YOU SET
Zones with the access levels you choose

Outside

External network activity

Traffic crossing the boundary. Unsolicited inbound attempts are filtered, and outbound connections are measured against policy — which is how activity that does not fit the pattern gets noticed.

External network protectionConnection attempts approach the network from outside. Unsolicited inbound traffic, port scans and unknown hosts are stopped at the perimeter, while requested traffic such as a web page, a video stream and a software update is allowed through.YOUR NETWORKPERIMETER POLICY APPLIEDUNSOLICITED INBOUNDPORT SCANUNKNOWN HOSTREQUESTED PAGEVIDEO STREAMSOFTWARE UPDATEUNWANTED CONNECTIONEXTERNAL NETWORK ACTIVITY

Cloud-managed

Nothing to maintain, nothing to update, nothing to forget.

Policy, inspection and monitoring run as a managed service. Updates are applied centrally, so the protection does not depend on someone remembering to check a settings page.

Monitoring runs continuously and decisions are recorded, which means an action can be reviewed later and explained in plain terms rather than taken on trust.

What this depends on

Setup steps, available options and reporting depth vary with your equipment, internet service and selected plan.

Getting started

What actually happens when you get in touch.

  1. Describe your setup

    Your internet service, your router and roughly what is connected. A couple of sentences is enough to start.

  2. We explain the fit

    Which configuration suits your household, what it will cover, and anything that depends on your specific equipment.

  3. Protection is applied

    Policy is configured at the network level and monitoring begins. Support stays available for adjustments.

FAQ

Home firewall questions.

What is a home firewall, in plain terms?

It is a checkpoint between your home network and the internet. Every connection that crosses that boundary is checked against a set of rules. Traffic you asked for goes through; traffic that matches a block rule does not. Because it sits at the boundary, it covers everything connected behind it.

Isn't my router's firewall enough?

Most routers include basic filtering, which is genuinely useful and worth having switched on. A managed service adds maintained policy, ongoing monitoring, recorded decisions and someone to call when something needs changing. The two are complementary rather than alternatives.

Which devices are covered?

Anything that connects through the protected network: computers, phones, tablets, TVs and streaming boxes, games consoles, cameras, speakers, printers, plugs, thermostats and other smart appliances. Coverage follows the network connection, not an installed app.

Do I need technical knowledge to use it?

No. The service is configured for you with defaults suited to a household, and support handles changes. You do not need to write rules, read logs or understand port numbers to benefit from it.

What about devices using mobile data instead of Wi-Fi?

Network-level protection applies to traffic crossing your home network. A phone on a mobile connection is outside that boundary until it reconnects to your Wi-Fi. This is worth knowing rather than glossing over — protection follows the network, not the device.

Can policy be adjusted for my household?

Yes. Rules can be adapted — for example around guest access or a particular device — and support can review a recorded decision and change the policy behind it. Available options depend on your service configuration.

Will my streaming, gaming or video calls be affected?

Everyday use is designed to feel normal. Inspection adds minimal delay, though actual performance depends on your connection, your router and the configuration in place. If something specific behaves oddly, support can look at what policy applied to it.

How do I get started?

Get in touch through the support page and describe your setup: your internet service, your router, and roughly what is connected. We will explain which configuration fits and what setup involves.
