For most small offices that want managed intrusion prevention, I’d start with the Fortinet FortiGate 70G for its newer platform and bundled FortiGuard services. The FortiGate 40F is a smaller-footprint alternative, while the Netgate 1100 suits buyers who value pfSense+ and hands-on control. The main tradeoff is between an integrated security service and the flexibility of managing your own rules, updates, and detection tools. Appliance capacity, subscription needs, and setup effort can matter as much as the feature list. Read on for how the ten options differ and which fits your network.

Key Takeaways
- Managed threat services shape the FortiGate picks: the 70G bundle includes three years of FortiGuard Enterprise Security Services, while the 40F and 60F listings do not specify the same bundle.
- Choosing a larger model should follow measured network demand: the 90G and 70G are the higher-tier Fortinet options here, but throughput under enabled security inspection matters more than model numbering alone.
- pfSense+ and a mini PC favor control over turnkey operation: the Netgate 1100 and Protectli Vault FW4B make sense for buyers willing to configure and maintain their own security stack.
- Simple setup is a different priority from deep tuning: Firewalla Purple SE and Aruba Instant On Secure Gateway are aimed at buyers who want approachable network management, while SonicWall and Fortinet offer more security configuration choices.
- Firewall capability does not prove IDS/IPS suitability by itself: confirm supported detection features, licensing, update terms, and inspected throughput for the exact configuration before buying.

More Details on Our Top Picks
Fortinet FortiGate 40F Firewall Appliance (FG-40F), 5 Gigabit Ethernet Ports
The FortiGate 40F suits a small office that wants a quiet, compact appliance with a stated IPS throughput up to 1 Gbps. Its five Gigabit ports cover a basic WAN and internal network layout, while the fanless desktop design can sit near staff without adding fan noise. Compared with the FortiGate 60F, it gives up five ports and some stated threat protection throughput, but takes less space and keeps the setup simpler for a smaller site. The main catch for IDS/IPS buyers is that this unit is sold without a subscription, so the included hardware alone does not establish what security services will be available or their ongoing cost. It is also wired only, with no wireless access point built in.
Pros:- Fanless desktop design supports quiet placement in a small office.
- Five Gigabit Ethernet ports provide one WAN and four internal connections.
- Stated IPS throughput reaches up to 1 Gbps.
- FortiOS provides a platform for Fortinet security capabilities.
Cons:- Security subscription is not included, so service coverage requires separate planning.
- Only four internal ports may constrain offices with several wired network segments.
- Wired connectivity only; wireless access requires separate equipment.
Best for: Small businesses or branch offices that need a quiet wired firewall for a modest number of network segments and can arrange the required security services.
Not ideal for: Teams that need included, multi-year threat services, built-in Wi-Fi, or more than four internal Ethernet connections.
- Model:FG-40F
- Ports:5 Gigabit Ethernet RJ45: 1 WAN, 4 internal
- IPS throughput:Up to 1 Gbps
- Threat protection throughput:Up to 600 Mbps
- Form factor:Fanless desktop
- Operating system:FortiOS
- Subscription:Not included
Our verdict“Choose the FortiGate 40F for a quiet, compact small-office IDS/IPS appliance if you are prepared to source its security subscription separately.”
Fortinet FortiGate-70G Firewall with 3-Year FortiGuard Enterprise Security Services
The FortiGate-70G is the clearest fit here for a branch office that wants stated IDS/IPS capacity alongside a defined security-services term. Its 2.5 Gbps IPS throughput and bundled three-year FortiGuard Enterprise Security Services distinguish it from the FortiGate 40F and 60F, which are described as appliance-only. The ten GE RJ45 ports, including WAN and DMZ connections, also give a growing site more room to separate traffic. Centralized management and zero-touch deployment can reduce setup work across distributed locations. That added capacity and service coverage come with a more involved branch firewall setup than a compact, basic gateway; the product description does not specify support for larger network environments. Buyers should match its throughput figures to their own traffic and inspection needs.
Pros:- Stated IPS throughput of 2.5 Gbps is higher than the FortiGate 40F and 60F figures.
- Three-year FortiGuard Enterprise Security Services are included.
- Ten GE RJ45 ports include two WAN ports and a DMZ port.
- Centralized management and zero-touch deployment support multi-site rollouts.
Cons:- Branch and small-office positioning may not suit larger network environments.
- The available product details do not specify a wireless access point.
- Buyers should confirm service scope and throughput fit for their inspection policies.
Best for: IT teams deploying security-managed firewalls across small or midsize branches that want three years of FortiGuard Enterprise services included.
Not ideal for: Home users or very small offices that need only a basic gateway, as well as larger networks whose capacity needs exceed the stated branch-office design.
- Model:FG-70G-BDL-809-36
- IPS throughput:2.5 Gbps
- Threat protection throughput:1.3 Gbps
- SSL inspection throughput:1.4 Gbps
- Ports:10 GE RJ45: 7 internal, 2 WAN, 1 DMZ
- Security services:3-year FortiGuard AI-powered Enterprise Security Services
- Management:Centralized management and zero-touch deployment
Our verdict“Choose the FortiGate-70G if your branch needs higher stated IPS capacity, flexible ports, and a three-year FortiGuard service bundle.”
FortiGate 60F Firewall Appliance (FG-60F)
With ten Gigabit Ethernet ports, including two WAN connections and a DMZ port, the FortiGate 60F stands out for offices that need to divide networks across several physical interfaces. Its stated 1.4 Gbps IPS throughput is above the 40F’s 1 Gbps figure, and it adds SSL inspection and SD-WAN. That makes it a more flexible fit for a multi-segment branch than the smaller 40F. The 70G, however, lists higher IPS and threat protection throughput and includes three years of FortiGuard Enterprise services. The 60F is sold without a subscription, so buyers need to account for security-service requirements separately. Its choice makes most sense when port layout and familiar Fortinet features matter more than an included service term.
Pros:- Ten Gigabit Ethernet ports include two WAN, one DMZ, and seven internal ports.
- Stated IPS throughput reaches 1.4 Gbps.
- SSL inspection and SD-WAN support broader traffic and link management needs.
- Network automation and Security Fabric integration support Fortinet environments.
Cons:- No subscription is included, so security-service coverage must be arranged separately.
- The 70G offers higher stated IPS and threat protection throughput with a three-year service bundle.
- Its ten ports may be more than a very small office needs.
Best for: Small and midsize branch IT teams that need multiple wired segments, a DMZ, and two WAN connections on one appliance.
Not ideal for: Buyers who want a bundled security-services term or whose inspection needs call for throughput above the 60F’s stated figures.
- Model:FG-60F
- Ethernet ports:10 Gigabit Ethernet RJ45
- Port layout:2 WAN, 1 DMZ, 7 internal
- IPS throughput:Up to 1.4 Gbps
- Threat protection throughput:700 Mbps
- Features:SSL inspection, SD-WAN, network automation, Security Fabric integration
- Subscription:Not included
Our verdict“Pick the FortiGate 60F when ten ports, two WAN links, and a DMZ matter more than bundled security services or the 70G’s higher stated throughput.”
Aruba Networking Instant On Secure Gateway
The Aruba Instant On Secure Gateway is the lineup’s cloud-management choice: remote monitoring and administration run through the Instant On portal or app, with automated firmware updates. For a small business without a dedicated network administrator, that can make routine oversight easier than managing a more hands-on appliance such as the Netgate 1100 with pfSense+. Its Zero Trust architecture and hardware-accelerated firewall are relevant security features, but the supplied product data gives no IDS/IPS throughput figure. That makes it harder to compare directly with FortiGate models whose IPS capacity is stated. WAN redundancy and load balancing help businesses that need resilient internet links. The SG2505P variant adds up to 60W PoE+ and multi-gigabit WAN ports; those specifications should not be assumed for every model under this listing.
Pros:- Remote management is available through the Instant On Cloud Portal or app.
- Automated cloud firmware updates reduce routine update work.
- WAN redundancy and load balancing support resilient internet connectivity.
- SG2505P variant offers up to 60W PoE+ and multi-gigabit WAN ports.
Cons:- The supplied product details do not state IDS/IPS throughput, limiting direct capacity comparisons.
- PoE+ and multi-gigabit WAN specifications apply specifically to the SG2505P variant.
- Cloud-based administration may not suit teams seeking local-only management.
Best for: Small businesses already using Aruba Instant On that want cloud-based gateway monitoring, remote management, and automated firmware updates.
Not ideal for: Buyers who need a stated IDS/IPS throughput figure or who require PoE+ and multi-gigabit WAN without confirming they are selecting the SG2505P model.
- Management:Instant On Cloud Portal or app
- Security:Zero Trust architecture and hardware-accelerated firewall
- WAN features:Redundancy and load balancing
- Firmware:Automated cloud firmware updates
- SG2505P PoE+ budget:Up to 60W
- SG2505P WAN ports:Multi-gigabit
Our verdict“Choose the Aruba gateway for convenient cloud management and WAN resilience, after confirming the selected model’s IDS/IPS capacity and variant-specific ports.”
Netgate 1100 pfSense+ Security Gateway Firewall Router
The Netgate 1100 pairs a compact, silent enclosure with pfSense+ preloaded and lifetime software updates. Its three switched 1 GbE ports and stated firewall throughput of over 650 Mbps make it a modest gateway for a small network, while included TAC Lite support offers a route to setup help. This is a different proposition from the FortiGate 40F: the Netgate highlights its software and support package, whereas the FortiGate lists a specific IPS throughput figure and Fortinet threat protection capabilities. The Netgate’s supplied data does not state IDS/IPS throughput, so buyers focused on inspected traffic capacity should verify that fit before choosing it. Three ports also leave less room for separate wired segments than the ten-port FortiGate 60F.
Pros:- pfSense+ is preloaded and lifetime software updates are included.
- TAC Lite technical support and setup assistance are included.
- Compact, low-power design supports silent operation.
- Stated firewall throughput exceeds 650 Mbps.
Cons:- Only three switched 1 GbE ports limit wired segmentation.
- The supplied specs do not state IDS/IPS throughput.
- The FortiGate 40F provides a specific IPS throughput figure for capacity comparison.
Best for: Technically comfortable home-office or small-business users who want a quiet pfSense+ gateway with software updates and included setup support.
Not ideal for: Buyers who need a documented IDS/IPS throughput figure, many physical network segments, or more than 650 Mbps of stated firewall throughput.
- Processor:Dual-core ARM Cortex-A53, 1.2 GHz
- Firewall throughput:Over 650 Mbps
- Ethernet ports:Three switched 1 GbE ports
- Software:pfSense+ preloaded; lifetime updates included
- Technical support:TAC Lite included; setup assistance available 24/7/365
- Hardware warranty:One year
- Design:Compact, low-power, silent operation
Our verdict“Choose the Netgate 1100 for a quiet, supported pfSense+ gateway if its three ports and unstated IDS/IPS capacity fit your network.”
SonicWall TZ280 Next-Generation Firewall Appliance
The SonicWall TZ280 stands out for buyers who need several wired connections and room to add fiber links: it has eight 1GbE ports and two 1G SFP ports. Its stated firewall inspection rate reaches 2.5 Gbps, while threat prevention reaches 1 Gbps, a distinction buyers should weigh against their expected traffic with security services enabled. Compared with the Firewalla Purple SE, the TZ280 is geared toward a managed business network with more physical interfaces; Firewalla offers easier app-guided home controls but caps IPS at 500 Mbps. The tradeoff is ongoing cost: security services, firmware updates, and support require a separate subscription. I’d shortlist it for a small office that values port flexibility and can budget for that service plan.
Pros:- Eight 1GbE ports plus two 1G SFP ports support varied wired connections.
- Firewall inspection is rated up to 2.5 Gbps.
- Threat prevention and IPsec VPN throughput are specified separately.
- Supports on-box or cloud management, VPN, and SD-WAN.
Cons:- Security services require a separate subscription.
- Firmware updates and support are sold separately.
Best for: Small offices that need multiple wired connections, SFP links, and on-box or cloud management.
Not ideal for: Buyers seeking an appliance with included security services, firmware updates, and support.
- Firewall inspection throughput:Up to 2.5 Gbps
- Threat prevention throughput:Up to 1 Gbps
- IPsec VPN throughput:Up to 1.2 Gbps
- Ports:8x 1GbE, 2x 1G SFP
- Operating system:SonicOS 8
- Form factor:Desktop
- Management:On-box or cloud via Network Security Manager
- Subscription:Security services, firmware updates, and support sold separately
Our verdict“Choose the TZ280 if port variety and business-oriented management matter more than included subscriptions.”
Fortinet FortiGate 90G Next-Generation Firewall Appliance
The FortiGate 90G is the lineup’s business-scale choice, with a stated target of 200–500 users and security functions that include intrusion prevention, web filtering, application control, and antivirus. Its two shared 10GbE RJ45/SFP+ WAN ports give network teams flexible uplink options alongside eight Gigabit Ethernet ports. Compared with the Fortinet FortiGate 40F, the 90G is aimed at a much larger organization and offers faster WAN interfaces; the 40F’s five Gigabit ports suit a smaller footprint. The cost of that scale is more planning around Fortinet’s ecosystem: no security subscription is included, and the supplied details don’t state throughput figures. I’d favor it when the organization’s user count and uplink needs justify a larger appliance.
Pros:- Includes intrusion prevention, web filtering, application control, and antivirus features.
- Two shared 10GbE RJ45/SFP+ WAN ports offer uplink flexibility.
- Eight Gigabit Ethernet ports provide wired connectivity.
- Designed for medium-sized networks of 200–500 users.
Cons:- No security service subscription is included.

- Target organization size:200–500 users
- Included subscription:No
Our verdict“Pick the FortiGate 90G for a medium-sized network that can support Fortinet subscriptions and needs 10GbE WAN options.”
Protectli Vault FW4B 4-Port Fanless Firewall Mini PC with Intel Celeron J3160
The Protectli Vault FW4B is the DIY pick for buyers who want to choose and configure their own firewall software. Its four Intel Gigabit Ethernet ports, fanless cooling, and AES-NI support make it a quiet, compact base for systems such as pfSense or OPNsense. Unlike the ready-to-manage Netgate 1100 pfSense+ Security Gateway, this Vault arrives without RAM, mSATA storage, or a preinstalled operating system; that means more choice, but also more setup and compatibility work for the buyer. Its Celeron J3160 hardware is an older, modest platform, and the supplied data gives no IPS throughput figure, so I wouldn’t choose it for a demanding high-speed network without checking performance for the intended software and ruleset. It fits hands-on users who value control over turnkey setup.
Pros:- Four Intel Gigabit Ethernet ports support separate network segments.
- Fanless design runs silently.
- AES-NI hardware support can assist encryption workloads.
- Tested with pfSense, Untangle, OPNsense, and other open-source software.
Cons:- RAM and mSATA storage must be supplied separately.
- No operating system is preinstalled, so setup requires technical effort.
- The provided data does not state IDS/IPS throughput.
Best for: Technically capable home lab and small-office users who want to install and maintain their own open-source firewall system.
Not ideal for: Buyers who need a preconfigured appliance, included storage and memory, or stated IDS/IPS throughput.
- Processor:Intel Celeron J3160, quad-core, 64-bit
- Maximum processor speed:Up to 2.2 GHz
- Hardware encryption:AES-NI
- Ethernet ports:4 Intel Gigabit Ethernet
- USB ports:2 USB 3.0
- Cooling:Fanless
- Memory and storage:No RAM or mSATA included
- Operating system:Not preinstalled; tested with pfSense, Untangle, OPNsense, and other open-source software
Our verdict“Choose the FW4B if you want a silent, customizable firewall base and are comfortable supplying and installing its components.”
Firewalla Purple SE Cybersecurity Firewall
The Firewalla Purple SE is the most approachable home-focused option here, pairing app-guided setup with intrusion prevention, malware and ad blocking, parental controls, and network activity insights. Its router and transparent bridge modes give households a choice between replacing their router’s routing role or adding protection alongside existing equipment. Compared with the Protectli Vault FW4B, Purple SE arrives as a managed security product rather than a barebone system that needs parts and an OS installed. That convenience comes with a clear ceiling: IPS is limited to 500 Mbps, which may constrain faster connections when inspection is active. Router mode also needs a modem and separate Wi-Fi access points, while existing router configuration can add setup work. This is a better fit for homes and small businesses than networks needing higher IPS capacity.
Pros:- Includes intrusion prevention and network threat blocking.
- Parental controls and content filtering support household management.
- Can operate in router or transparent bridge mode.
- App provides network activity and bandwidth insights.
Cons:- IPS data rate is limited to 500 Mbps.
- Setup may require changes to the existing router.
- Router mode requires a modem and separate Wi-Fi access points.
Best for: Households and very small businesses that want app-managed intrusion prevention, parental controls, and network visibility.
Not ideal for: Users with internet speeds above its 500 Mbps IPS capacity or those expecting an all-in-one modem and Wi-Fi router.
- Model:Purple SE
- IPS data rate:Up to 500 Mbps
- RAM:3 GB
- Connectivity:Ethernet and Wi-Fi
- Wi-Fi generation:Wi-Fi 5
- Operating system:Linux
- Control method:App
- Router modes:Router mode and transparent bridge mode
Our verdict“Choose Purple SE for accessible app-led home security if its 500 Mbps IPS ceiling and separate network equipment fit your setup.”
SonicWall TZ380 Network Security Firewall Appliance
The SonicWall TZ380 is a straightforward desktop appliance for buyers who prioritize a row of wired connections and basic firewall plus intrusion prevention features. Its eight Ethernet ports give a small network room to connect devices or divide traffic across segments. Compared with the SonicWall TZ280, this listing provides less decision-useful detail: it names no inspection or threat-prevention throughput, SFP ports, VPN rate, or management options. The mention of MD5 is also a dated specification and should not be mistaken for a reason to choose it as a modern security advantage. I’d consider it only after confirming supported security services, update terms, and performance with the seller or vendor. Buyers who need documented capacity and current service details have a stronger basis for comparison with the TZ280.
Pros:- Includes firewall and intrusion prevention features.
- Eight ports provide wired connection capacity.
- Desktop form factor suits an office or equipment shelf.
- USB connectivity is listed for connecting devices and transferring data.
Cons:- The provided product data does not state inspection or threat-prevention throughput.
- MD5 is an older hash algorithm and offers no compelling modern security advantage.
- Management and subscription details are not provided.
Best for: Small wired networks that need a desktop firewall with eight Ethernet ports and basic intrusion prevention.
Not ideal for: Buyers who need published IDS/IPS throughput, detailed management capabilities, or clear security service and update terms.
- Ports:8
- Installation:Desktop
- Connectivity:Gigabit Ethernet, USB
- Security features:Firewall, intrusion prevention
- Hash algorithm:MD5, 128-bit
Our verdict“Consider the TZ380 only if eight wired ports and basic intrusion prevention meet your needs and you can verify its missing performance and service details.”
How We Picked
I ranked these appliances around their fit for intrusion detection and prevention, looking at the security features and services identified for each product, expected management effort, platform flexibility, and the practical fit for a home or small office. I also weighed whether ongoing services or software configuration are part of the choice, since an IDS/IPS feature that is not licensed, updated, or tuned may not meet a buyer’s needs.
The FortiGate 70G leads for buyers seeking a newer Fortinet platform with a clearly stated three-year security-services bundle. The 40F and 60F offer compact alternatives, while the 90G targets buyers considering a higher-tier appliance. Netgate and Protectli rank for buyers who prize control and can take on configuration. Aruba, Firewalla, and the SonicWall models serve different management and security preferences; their exact IDS/IPS features and service requirements should be checked against the intended deployment before purchase.

Factors to Consider When Choosing Best IDS IPS Firewall Appliance
Before choosing an appliance, I’d define what the network needs to detect, how much traffic it must inspect, and who will maintain it. The following decisions can prevent a feature-rich gateway from becoming either a bottleneck or an underused box.
Check inspected throughput, not just port speed
Firewall throughput figures can describe traffic handled without every security feature enabled. Intrusion prevention, application control, and encrypted traffic inspection may reduce the capacity available to real workloads. Estimate peak traffic and leave room for growth, especially if several users stream, transfer large files, or connect remotely at once. Ask vendors for throughput under the specific inspection features you plan to use. A box with fast ports can still be a poor fit if inspection performance falls below your connection speed. Avoid choosing by the model number or headline throughput alone.
Map the ongoing service and license costs
Many managed detection feeds and security services depend on an active subscription. Compare the included term, renewal requirements, update coverage, and feature availability after that term ends. A bundle may simplify deployment because the service is ready to activate, but it can tie ongoing protection to a vendor plan. Open platforms can reduce dependence on a single service provider, yet you may need to source, configure, and maintain components yourself. Ask what happens when a license expires before treating a feature as a permanent appliance capability. Include staff time and renewal administration in the ownership decision.
Choose the management burden your team can handle
IDS/IPS requires more than switching on a checkbox: alerts need review, rules need tuning, and false positives can disrupt work. A managed appliance may package updates and policy controls in a more guided workflow, while a flexible platform can expose more settings and responsibility. Decide who will respond to alerts and how quickly they can do so. For a home or small office without an IT owner, ease of setup and clear notifications may matter more than extensive customization. Technical buyers should still account for the hours needed to maintain a custom configuration. A system no one monitors can create noise without improving response.
Plan for encrypted traffic and privacy
Much network traffic is encrypted, which limits what a gateway can inspect unless it performs some form of TLS inspection. That can require certificates on client devices, create compatibility issues, and expose sensitive traffic to inspection. Check which protocols and inspection modes the appliance supports and whether those functions need a separate license. Consider which device groups or destinations should be excluded for privacy or compatibility reasons. Do not assume an IDS/IPS label means every threat inside encrypted sessions will be visible. Set a policy that balances detection goals with user privacy and operational needs.
Match ports and topology to the real network
Count the physical connections needed for internet access, internal networks, guest devices, and any separate IoT or work segments. A compact appliance may have enough ports for a simple layout but require a managed switch for more zones. Check whether the system supports VLANs and whether those settings are practical to administer. Consider WAN failover, access point integration, and remote access needs before installation. Buyers sometimes focus on raw port count and overlook how security zones will be separated. Sketching the network first can reveal whether a gateway alone will do the job.
Compare appliance ownership with software flexibility
A dedicated appliance offers a purpose-built package, while a mini PC running firewall software can let the owner choose interfaces and software components. That flexibility also shifts responsibility for compatibility, updates, backups, and hardware support. Check whether the manufacturer supplies security updates and how long the hardware is expected to receive support. A fanless design can suit quiet spaces, but thermal conditions and sustained load still matter. Verify that network interfaces are supported by the chosen software and that the system can recover cleanly after power loss. Pay more for a managed ecosystem when saved administration time is worth more than custom control.
Frequently Asked Questions
Do I need a security subscription for IDS/IPS to work?
That depends on the appliance and which detection features you plan to use. Some products rely on vendor subscriptions for threat intelligence, signature updates, or advanced security services, while software-based options may let you select and maintain components separately. Check whether the included service is time-limited and what protection remains after it expires. Also confirm update frequency and whether the appliance still receives firmware fixes without the security bundle. Treat the subscription as part of the ongoing operating cost, not just a setup detail.
Will an IDS/IPS firewall slow down my internet connection?
It can, especially when traffic inspection, application controls, or encrypted traffic analysis are enabled. The relevant figure is throughput with your intended security features active, rather than the appliance’s basic routing speed. Compare that figure with peak usage and leave headroom for growth. If the vendor does not publish performance for the configuration you need, ask before purchase. A suitable appliance should inspect traffic without becoming the network’s routine bottleneck.
Is a self-managed firewall a good choice if I do not have IT staff?
It can work for a technically confident owner, but self-managed platforms make the buyer responsible for setup, updates, rule tuning, and alert review. The initial installation is only part of the workload; ongoing care is what keeps detection useful. If no one can own those tasks, prioritize guided setup, clear alerts, and a support plan. A more flexible firewall is not automatically safer if its rules are left at defaults or alerts go unread. Estimate the time you can actually devote before choosing flexibility over managed services.
Can one firewall appliance separate work, guest, and IoT devices?
Often, but the appliance must support network segmentation through features such as VLANs or separate interfaces, and your switches and access points must carry those segments too. Plan the zones before buying so you know how many networks and policies you need. Guest access usually calls for internet connectivity without access to internal devices, while IoT devices may need narrowly limited exceptions. Confirm that the management interface makes these policies understandable to the person who will maintain them. A gateway cannot create meaningful separation if the rest of the network ignores the segmentation design.
Should I replace my router with an IDS/IPS appliance or add one behind it?
Either layout can work, but running two routers may create double NAT and complicate inbound services, VPNs, and troubleshooting. Replacing the existing router can simplify policy enforcement if the appliance supports your WAN connection and wireless setup. Placing it behind the current gateway may be easier to trial, though traffic that bypasses it will not receive the same inspection. Check bridge or passthrough options with your internet provider and current router. Choose the layout that puts all relevant traffic through the appliance without creating a setup no one can maintain.
Conclusion
For a small office that wants a managed security bundle, I’d choose the FortiGate 70G as the best overall fit in this group. The FortiGate 40F is a compact alternative, while the Netgate 1100 is my value-oriented choice for a buyer who can manage pfSense+ configuration. For beginners, I’d look first at Firewalla Purple SE or the Aruba Instant On Secure Gateway, then verify the exact IDS/IPS features and service terms that matter. Buyers with higher capacity needs can compare the FortiGate 90G and SonicWall TZ380; those seeking a premium managed path should examine the 70G bundle and confirm its fit against their traffic and licensing needs. Choose the Protectli Vault FW4B when quiet, flexible hardware matters and you are comfortable maintaining the software stack yourself.
