A business firewall quote often only shows the hardware price, which is misleading - licensing and management typically add up to more than the hardware itself over the device's working life. Here's the full picture.
Three Cost Components, Not One
1. Hardware
The upfront cost of the physical device, sized to your internet speed, number of users, and required features. For a small-to-medium office, expect $800-$2,500. Larger offices or businesses needing higher throughput for SD-WAN or heavy VPN use can run $2,500-$6,000+.
2. Security Licensing
An annual subscription covering threat intelligence, intrusion prevention, content filtering, and vendor support - typically $300-$1,200 per year depending on the feature set and device tier. This is not optional if you want the firewall to function as an active security tool rather than a basic router. See our guide on FortiGate firewalls for Perth businesses for how one major vendor structures this.
3. Configuration and Ongoing Management
Initial setup - VPN configuration, VLAN segmentation, rule creation - is typically a one-off cost of $500-$2,000 depending on complexity. Ongoing management (monitoring, firmware updates, rule reviews) is either bundled into a managed IT agreement or billed separately, commonly $100-$400 per month for a small business.
Total Cost Over Five Years
For a typical small office, budget roughly $3,000-$8,000 in hardware and setup upfront, plus $400-$1,600 per year in licensing and management ongoing - meaning licensing and management often exceed the original hardware cost well before replacement time.
Why the Cheapest Firewall Rarely Works Out Cheapest
A consumer-grade router marketed as a "firewall" avoids the licensing cost entirely, but it also lacks intrusion prevention, content filtering, and the visibility a business actually needs. The savings are real but the protection gap is real too - this is a false economy for any business handling client data or dependent on network uptime. See our guide on network security for Perth businesses for what a firewall should actually be protecting against.
What to Check Before Buying
- Is the security licence included in the initial quote, or a separate renewal you'll discover later?
- Is the device sized correctly for your actual internet speed - an undersized firewall becomes a bottleneck
- What's the vendor's end-of-life date for this model, so you know your realistic replacement horizon
- Is ongoing management included, or will monitoring and updates fall to someone internally?
Frequently Asked Questions
Can I buy a firewall without the annual security licence to save money?
Technically yes, but doing so means running the firewall without active threat intelligence, intrusion prevention, or content filtering updates - effectively a much less capable device that still requires the same setup effort. This isn't a genuine cost saving once you weigh up what you're giving up.
Why do firewall licences need to be renewed every year?
The licence covers ongoing threat intelligence feeds, security signature updates, and vendor support - all of which need to stay current to be effective. A firewall with an expired licence is still a router, in effect, without the active security features that justified the purchase.
Is it cheaper to manage the firewall myself instead of paying for managed management?
Only if you genuinely have the in-house expertise and time to monitor logs, apply firmware updates promptly, and respond to alerts. For most small businesses without a dedicated network specialist, an unmanaged firewall quietly becomes a misconfigured or outdated one over time, which defeats the purpose of having it.
How long does a business firewall typically last before replacement?
Generally 5-7 years, though this can be shorter if internet speeds or network demands grow faster than the hardware can handle, or if the vendor discontinues support for that model. It's worth checking end-of-life dates when purchasing, not just at replacement time.
