The best business firewall is no longer simply the appliance with the highest throughput or the longest specification sheet. For SMEs, the right firewall needs to support cloud services, hybrid working, multiple locations, secure remote access and an increasingly complex cyber threat landscape.
That means choosing a firewall should be an architecture decision, not simply a hardware purchase.
For many businesses, the firewall only receives serious attention when renewal approaches. The incumbent supplier proposes the next model; the licence is renewed and another three or five years are committed.
That may be the right decision but if your organisation has changed significantly since the existing firewall was installed, simply buying the newer version of what you already have could mean renewing an architecture designed for yesterday.
What Makes the Best Business Firewall for an SME?
There is no single firewall that is right for every SME.
The requirements of a 50-person professional services business are very different from those of a manufacturer operating several sites, or an organisation with hundreds of employees working between offices, home and cloud environments.
However, the questions businesses should ask have changed. A modern business firewall needs to do more than control traffic entering and leaving the network.
It should help an organisation:
- Protect users, devices and applications
- Inspect potentially malicious traffic
- Support secure remote and hybrid working
- Control access to business applications
- Connect multiple offices securely
- Support cloud and SaaS environments
- Provide useful security intelligence
- Integrate with wider monitoring and response
- Remain manageable without requiring a large internal security team
The best business firewall is therefore increasingly the one that fits into the wider technology and security architecture most effectively.
Performance Matters When Security Is Actually Switched On
Firewall specifications frequently lead with impressive throughput figures. However, headline speed is only part of the story. Intrusion prevention, malware detection, application inspection, encrypted traffic inspection and other security controls all place additional demands on the firewall.
For an SME assessing its next firewall, the more useful question is not simply: How fast is the firewall? It is: How fast is the firewall when the security capabilities we actually need are enabled?
This is one of the areas where we believe Fortinet has a strong architectural advantage.
FortiGate firewalls use purpose-built ASIC Security Processing Units to accelerate networking and security workloads. For businesses with substantial traffic volumes, multiple locations or increasingly sophisticated security requirements, that architecture can become particularly valuable.
Security features are only useful if the organisation can afford to keep them switched on without creating unacceptable network performance problems.
The Best SME Firewall Should Be More Than a Firewall
The firewall used to be a relatively isolated technology. That is becoming increasingly difficult to justify. Most SMEs have accumulated their technology over time. A firewall from one supplier. Networking from another. Remote access added separately. Endpoint protection elsewhere. Cloud services introduced later. Perhaps another product for monitoring and another for identity.
Each decision may have been perfectly sensible. Collectively, however, they can create complexity. More consoles. More policies. More licences. More support arrangements. More places where visibility can disappear between technologies.
This is one reason we increasingly look at the firewall as part of a wider security architecture rather than as an isolated appliance.
FortiGate sits within the wider Fortinet Security Fabric, with FortiOS providing a common foundation across networking and security. The advantage is not that every technology in the organisation suddenly needs to become Fortinet. It is that the firewall has the ability to operate as part of a broader architecture, sharing policy, visibility and security intelligence rather than simply protecting the network edge.
For an SME with limited internal resources, that can make security considerably easier to manage.
Secure SD WAN Can Change the Firewall Conversation
For multi-site SMEs, the firewall decision can also become a connectivity decision. Traditional branch environments may include separate firewalls, WAN services, VPN infrastructure and networking hardware. Secure SD WAN offers an opportunity to bring some of those requirements together.
Fortinet Secure SD WAN is integrated with FortiGate and FortiOS, allowing network connectivity and security policy to be managed as part of the same architecture.
For businesses reviewing MPLS, opening new offices or trying to improve resilience between locations, that can make a firewall replacement much more strategically important.
Instead of simply replacing an ageing appliance, the organisation can consider whether its wider connectivity model still makes sense.
The firewall project becomes part of a network modernisation programme.
Remote Working Has Changed What Businesses Need From a Firewall
Many existing firewalls were selected before hybrid working became normal. Remote access traditionally relied heavily on a simple principle. A user was outside the corporate network. They connected through a VPN. They were then effectively treated as being inside it.
Modern security needs to be more sophisticated.
Access decisions should increasingly consider who the user is, what device they are using, the condition of that device, which application they need and the context of the connection.
This is the principle behind Zero Trust Network Access (ZTNA).
Fortinet integrates ZTNA capabilities through technologies including FortiGate and FortiClient, helping organisations move towards access based on identity and device posture rather than relying purely on network location.
For SMEs supporting hybrid employees, contractors and cloud applications, this should increasingly be part of the firewall discussion.
Threat Intelligence Matters
A modern firewall cannot operate effectively using static rules alone. Threats change too quickly. New malicious infrastructure appears. New vulnerabilities emerge. Attack techniques evolve.
Security controls therefore need access to continuously updated threat intelligence.
FortiGuard Labs provides the threat intelligence behind Fortinet technologies, using AI and machine learning across a range of security services. That intelligence can be consumed across Fortinet technologies including FortiGate.
For SMEs without a large internal security function, this matters.
The firewall becomes more than something configured once and periodically updated. It becomes part of a security environment that is continually responding to changes in the threat landscape.
Your Firewall Should Contribute to Security Monitoring
A firewall sees a considerable amount of useful security information. It sees connections between networks. It sees applications. It reviews suspicious traffic and may identify attempts to exploit vulnerabilities as well as enforcing segmentation.
In addition, it can also provide indicators that make much more sense when viewed alongside endpoint, identity and cloud activity.
That information should not simply remain inside the firewall.
At Amicis Group, we believe network security should form part of the wider cyber security operation. The question is not just whether the firewall blocked a connection. It is whether suspicious activity can be identified, understood and responded to quickly enough to prevent a wider incident.
For an SME using managed security services, integration between the firewall and wider monitoring can therefore be just as important as the specification of the appliance itself.
Is Fortinet the Best Business Firewall for Every SME?
No single platform is the right answer for every organisation. A smaller business with one location and straightforward requirements will have very different needs from a multi-site organisation with substantial cloud infrastructure, remote users and more demanding security requirements.
The existing environment also matters. Replacing a firewall has a cost. Policies may need migrating. Connectivity may need changing. Remote access may need redesigning. Internal teams may need training. There needs to be a genuine benefit to making that change.
However, for SMEs looking for a firewall platform that can scale beyond basic perimeter security, we believe Fortinet deserves serious consideration.
The strength is not simply FortiGate itself. It is the wider capability around it.
- Purpose-built security processing
- Secure SD WAN
- Zero Trust capabilities
- FortiGuard threat intelligence
- A common FortiOS platform
- Integration with wider security operations
For organisations looking to modernise networking and security together, that combination can be particularly compelling.
What Should You Review Before Choosing a Business Firewall?
Before deciding on a platform, start with the business rather than the product. Consider how many locations you operate. Look at how employees connect. Understand where your applications and data now sit. Review your use of Microsoft 365 and other cloud platforms. Look at your remote access arrangements. Consider whether your WAN and connectivity strategy is likely to change. Understand what your security team can currently see. Then look at what you expect the organisation to need over the next three to five years.
That will give you a much better basis for choosing a firewall than simply comparing specifications.
Do Not Automatically Renew What You Already Have
One of the easiest decisions in technology is renewing the incumbent. The team understands it. The policies already exist. The supplier sends the quote. Very little needs to change. But familiarity alone is not a good enough reason to commit to another three or five years.
If your firewall is approaching renewal, ask:
If we were designing our network and security architecture today, would we build it this way?
If the answer is yes, retaining the existing platform may be entirely sensible.
If the answer is no, renewal is an opportunity.
It is the point at which you can rethink connectivity, remote access, network security and how the firewall integrates with the wider technology environment.
