Why Does Your Office Need a Firewall?
Every device in your office, from laptops and printers to CCTV cameras, connects to the internet through a single path. Without a properly configured firewall, that path is open to unwanted access, and you have no control over what goes in and out of your network.
A firewall helps your office:
- Filter access from outside so that only the services you actually need are reachable from the internet.
- Segment the network for staff, guests, CCTV and servers, so a problem in one segment does not spread to others.
- Manage internet usage, for example by blocking certain sites or prioritizing bandwidth for business applications and video conferencing.
- Connect branch offices and remote employees securely over VPN.
- Log network traffic so the source of a problem is easier to trace when an issue occurs.
Our Firewall Services
- Site survey and network audit: reviewing devices, internet links and each department's needs before choosing a firewall.
- Firewall procurement: Fortinet or Cisco, sized to your number of users and internet speed.
- Security policy configuration: access policies, web filtering and network segmentation (VLAN).
- VPN: secure connections for branch offices and employees working outside the office.
- Dual internet links: automatic failover to a backup link when the primary link goes down.
- Documentation and handover: the configuration is documented and explained to your team.
- Maintenance: firmware updates, policy reviews and issue handling.
Recommending the Right Firewall for Your Office
A firewall that is too small will slow down your internet once its security features are enabled. A firewall that is too large wastes budget. Here is what we assess before making a recommendation:
| Factor | What we look at |
|---|---|
| Number of users and devices | Including CCTV, printers and guest devices |
| Internet speed | Firewall throughput with security features enabled, not just the maximum figure in the brochure |
| VPN requirements | Number of branch offices and employees connecting remotely |
| Security features | Web filtering, network antivirus and intrusion prevention |
| Licensing | Annual renewal cost of security features |
Our quotation lists several options along with their license costs, so you can compare the total cost, not just the device price.
Installation Process
- Site survey: reviewing the existing network and mapping each department's needs.
- Design and quotation: device recommendations, network segmentation design and written pricing.
- Configuration prep: security policies are prepared in advance to keep installation time short.
- Installation and testing: done outside working hours if needed, then tested together with your team.
- Handover and support: configuration documentation and post-installation assistance.
The Firewall as Part of Your Office Network
A firewall works best when the network behind it is also well organized: tidy cabling, VLAN-capable switches and a separate guest WiFi. That is why we usually review the firewall together with your overall office network installation. If you are setting up a new office, see our new office IT checklist as well.
For routine firewall and network upkeep after installation, we offer IT maintenance and support.
Office Firewall FAQ
Is the router from our internet provider enough?
It is usually enough for a home, but generally not for an office. ISP routers rarely offer the network segmentation, web filtering, stable VPN and traffic reports that companies need.
Which firewall brands does Techarg supply?
We work with Fortinet and Cisco for firewalls, and Ruijie and Ubiquiti for simpler office network needs. The choice depends on the number of users, internet speed and budget.
Will installing a firewall disrupt our office internet?
There is a short interruption when the old device is replaced. We prepare the configuration in advance and schedule the installation outside working hours so operations are not disrupted.
Does a firewall need maintenance after installation?
Yes. Firmware and security rules should be updated regularly, and security feature licenses must be renewed before they expire. We can handle this through a maintenance contract.
Can a firewall connect the head office and branches?
Yes. We configure site-to-site VPN so branches can securely access servers and applications at the head office.
