WatchGuard and Fortinet can both deliver effective firewall protection. That is not really the issue. The bigger question is how well each platform supports the modern organisation around it.
Fortinet has invested heavily in building an integrated security and networking architecture around FortiGate and FortiOS. That includes firewall protection, networking, Secure SD WAN, Zero Trust Network Access, endpoint integration, cloud security and wider security operations. In practical terms, that means organisations can begin to reduce the number of disconnected technologies they rely on.
For businesses managing increasingly complex IT environments, that matters. A firewall decision should no longer be based simply on whether the appliance can block threats. It should be based on whether the platform helps simplify, secure and modernise the wider environment.
Does your Firewall give you all you need?
Networks have changed significantly.
Cloud applications, hybrid-working, distributed offices and increasingly sophisticated cyber threats mean the firewall is no longer simply a device sitting at the edge of the network.
Modern organisations increasingly need networking, access, security and threat intelligence to work together.
For businesses reviewing their existing WatchGuard estate, Fortinet provides an alternative worth considering.
Fortinet vs WatchGuard: What Is the Difference?
One of Fortinet’s most significant architectural differences is its use of purpose-built security processors.
FortiGate appliances use dedicated ASIC Security Processing Units to accelerate network and security functions.
This is particularly relevant as organisations increasingly inspect encrypted traffic and enable additional security controls.
Traditionally, increasing the amount of security inspection can place additional demands on firewall performance. Fortinet’s approach is designed to process these workloads efficiently while maintaining network performance.
Performance is an important consideration when reviewing your existing firewall platform. Rather than simply asking whether a firewall can deliver a particular security feature, businesses should also ask: What happens to performance when those security capabilities are actually switched on?
1. Performance Matters When Security Is Actually Switched On
Firewall performance figures can look impressive on a specification sheet. The more important question is what happens when security controls are actually enabled.
Intrusion prevention, application inspection, encrypted traffic inspection, malware detection and other security services all create additional processing demands. Fortinet has designed FortiGate around purpose built security processors that accelerate networking and security workloads.
That gives Fortinet an architectural advantage.
Rather than relying entirely on general purpose processing, Fortinet uses dedicated ASIC based Security Processing Units to handle security intensive tasks.
For organisations running demanding environments, multiple sites, high traffic volumes or extensive security inspection, that difference can become significant.
The question should not be: How fast is the firewall? It should be: How fast is the firewall when we enable the security controls we actually need?
That is a much more useful measure.
2. FortiGate Is Part of a Wider Security Platform
This is probably one of the biggest differences organisations should consider. Many businesses have accumulated their technology estate gradually.
A firewall from one supplier. Remote access from another. Networking somewhere else. Separate endpoint protection. Another platform for SD WAN. Another for cloud security.
Each decision may have made sense at the time. Together, however, they can create complexity. More management consoles. More policies. More licences. More support arrangements. More places for visibility to break down.
Fortinet has taken a different approach.
FortiOS provides a common foundation across networking and security, while the wider Fortinet Security Fabric connects capabilities across network, endpoint, cloud and security operations.
The advantage is that the firewall does not have to operate as an isolated appliance. It can form part of a wider security architecture, sharing visibility, policy and intelligence with other parts of the environment.
For organisations reviewing their firewall estate, that can mean better integration, simpler management and a clearer view of what is happening across the network, without requiring every existing technology to be replaced.
3. Secure SD WAN Should Not Be an Afterthought
Networking and security are converging. That becomes especially important for organisations operating multiple locations. Traditional branch networks often involve separate firewalls, WAN connectivity, VPN infrastructure and networking hardware.
Fortinet Secure SD WAN brings networking and security together within the FortiGate platform. That allows organisations to manage connectivity and security policy as part of the same architecture.
This can create opportunities to simplify branch infrastructure, improve resilience and review expensive legacy connectivity models. For businesses already considering WAN changes, MPLS replacement or branch modernisation, the firewall refresh can become something much more valuable.
It can become a wider network transformation project.
4. Threat Intelligence Needs to Be Built Into the Security Architecture
Threats change continuously. A firewall that only relies on static configuration will quickly become less effective against modern attacks.
FortiGuard Labs provides the threat intelligence behind Fortinet technologies, using AI and machine learning across a range of security services.
That intelligence is integrated across products including FortiGate, Secure SD WAN, SASE and other Fortinet technologies. This matters because security technologies should not operate independently.
They should continuously benefit from new intelligence about malicious infrastructure, malware, vulnerabilities and emerging attacker behaviour.
For organisations with limited internal cyber security resources, automation and integrated threat intelligence can reduce the burden on internal teams.
5. Zero Trust Changes the Remote Access Conversation
Traditional remote access was simple. You were outside the network. You connected through a VPN. You were then effectively inside. That model is becoming increasingly difficult to justify.
Modern security needs to consider identity, device posture, application access and context. Zero Trust Network Access changes the principle from trusting the network location to verifying the user and device.
Fortinet integrates ZTNA capabilities through technologies including FortiGate and FortiClient. For organisations supporting hybrid workforces, cloud applications and distributed users, that is becoming increasingly important.
If remote working has changed dramatically since your current firewall was installed, your approach to access probably needs reviewing too.
6. Complexity Has Become a Security Problem
Technology complexity is not just an operational inconvenience. It can become a security weakness.
Every separate platform creates another configuration, another integration and another place where visibility can be lost. Over time, organisations can end up with a collection of technologies that individually work perfectly well but collectively become difficult to manage.
Fortinet’s approach is designed around bringing more of these capabilities together. That can mean fewer disconnected systems, more consistent policy and better visibility across the environment.
For many organisations, that is a stronger argument for change than any single firewall feature.
Should You Replace WatchGuard With Fortinet?
Renewal should not be automatic. If your WatchGuard environment is performing well and fully supporting your organisation, there may be good reasons to retain it. But if your requirements have changed, renewal is exactly the point at which you should challenge whether the existing architecture is still the right one.
If your organisation has changed significantly since the existing firewall estate was deployed, simply replacing it with the next model risks locking the business into an architecture designed for yesterday.
You should be asking whether:
- Your firewall is approaching renewal
- Performance drops when advanced security controls are enabled
- Your organisation operates multiple sites
- You are reviewing WAN or MPLS connectivity
- Remote access and Zero Trust are becoming more important
- Your cloud usage has increased significantly
- You are managing too many separate security platforms
- Your security team lacks visibility across network, endpoint and cloud
- Your firewall operates largely independently from your wider security monitoring
If several of those points apply, the issue is probably bigger than a firewall renewal.
It is an architecture review.
Why We Believe Fortinet Deserves Serious Consideration
Amicis Group works with Fortinet because we believe its approach is particularly well suited to organisations that want to bring networking and security closer together. The strength of Fortinet is not simply the FortiGate appliance. It is the wider architecture around it.
- Dedicated security processing.
- Integrated Secure SD WAN.
- Zero Trust capabilities.
- FortiGuard threat intelligence.
- A common FortiOS platform.
- Integration with wider security operations.
Together, these capabilities give organisations an opportunity to do more than replace an ageing firewall. They create an opportunity to simplify infrastructure, improve visibility and modernise the way network security is delivered.
That is where we believe Fortinet increasingly stands apart.
Do Not Renew Your Firewall Without Challenging It
The easiest option is usually to renew what you already have. The existing platform is familiar.
- The team already understands it.
- The policies already exist.
- The renewal quote arrives.
And another three or five years are committed.
There’s a chance that might be the right decision. But it should be a deliberate one. If your firewall estate is approaching renewal, this is the point to ask a more important question:
If we were designing our network and security architecture today, would we build it the same way? If the answer is no, renewing the existing estate without exploring alternatives could be a missed opportunity.
