In plain English
What SonicWall Firewalls does for your business
A SonicWall is the firewall that sits between your office network and the internet. It decides what traffic is allowed in and out, blocks known threats, filters risky websites and gives remote staff a secure way back into the office. Like any firewall, it only protects you if its firmware and security subscriptions are kept up to date.
Why people call us
Common SonicWall Firewalls problems we fix
Firmware years out of date
Out-of-date firewall firmware is one of the most common ways attackers get in. We check the version, apply updates and review remote access settings.
Security services quietly expired
Gateway antivirus and content filtering stop when the subscription lapses, and many businesses do not notice. We check what is active and what you are paying for.
VPN that only works for some people
Remote access often breaks after a laptop update or a change at the office. We find the cause and set it up consistently for every user.

Questions
SonicWall Firewalls FAQs
- Can you take over our existing SonicWall?
- Yes. We review the rules, firmware and subscriptions, tidy up anything risky and document how it is set up.
- Do we still need a firewall if we use the cloud?
- Usually yes, if you have an office network with PCs, printers or storage. The firewall protects everything on that network and controls remote access to it.
- How often should firmware be updated?
- Security updates should be applied when the vendor releases them, after a quick check that nothing important breaks. We can schedule and handle this for you.
- Is our SonicWall too old?
- Models that no longer receive updates should be replaced. We check the support status and tell you honestly whether it still has life in it.
