Managed Firewall Services

What managed firewall services include

Managed firewall services cover the work of keeping your firewall correctly configured, patched and watched, so it keeps blocking what it should after the day it was installed. A firewall is the device, or cloud service, that sits between your office network and the internet and decides which traffic is allowed in and out.

Firewall management usually breaks into four jobs:

• Configuration. Writing and reviewing the rules: which services are reachable from outside, which sites staff can visit, how guest Wi-Fi is separated from business systems.
• Updates. Applying firmware updates and keeping security subscriptions current. Most modern firewalls include intrusion prevention, web filtering and malware scanning that stop working when the subscription lapses.
• Remote access. Running the VPN or remote access gateway so staff can work from home without exposing internal systems.
• Monitoring. Watching for outages, attacks and configuration changes, and sending logs to whoever runs your security monitoring.

Small businesses usually get this from their managed IT provider as part of a per-user or per-device price. Larger or regulated firms sometimes buy it from a security provider as part of managed security services.

Why the network edge matters more in 2026

Firewalls, VPNs and other internet-facing devices are now the most common way attackers get in, which makes keeping them patched the most important job in firewall management. Verizon's 2026 Data Breach Investigations Report found exploitation of vulnerabilities was the top initial access route, at 31% of breaches ².

Insurer data points the same way. At-Bay reported that 80% of ransomware attacks against its insureds came in through a remote access tool ³. It also found that businesses using Cisco or Citrix SSL VPNs were nearly seven times more likely to be ransomware victims ³. That is not a reason to rip out a specific brand; it is a reason to patch remote access gear fast, require MFA on it, and retire it when the vendor stops issuing updates.

Cyber insurers check these controls. Marsh's list of twelve controls insurers look for includes MFA for remote access, RDP hardening, patch and vulnerability management, and replacing or protecting end-of-life systems ⁴. Our cyber insurance requirements page explains how applications ask about each one.

What a managed firewall costs

A managed firewall for a small business typically costs $50 to $300 per month for the service, on top of the hardware and its security subscriptions ¹. Huntress's 2026 cost guide puts entry-level firewall appliances at around $1,000, with renewals adding $100 to $1,000 a year ¹.

What moves you up or down that range:

• Number of sites. Each office, warehouse or clinic usually has its own firewall and its own fee.
• Change volume. A contract with unlimited rule changes costs more than one that bills changes hourly.
• High availability. A second firewall that takes over if the first fails roughly doubles the hardware and adds management work.
• Monitoring depth. Uptime alerts are cheap. Having analysts review firewall logs is a SOC service and is priced separately.
• Bundling. Many managed IT plans include firewall management in a per-user or per-device price. See our managed IT pricing guide.

Ask who owns the firewall and its admin passwords. If the provider leases the device or holds the only admin account, switching providers gets harder.

SD-WAN and SASE basics

SD-WAN manages traffic between your sites and the internet; SASE adds security in the cloud so the same rules follow users wherever they work. Both matter mainly to companies with several locations or many remote staff. A single-office firm usually needs a well-run firewall and nothing more.

• SD-WAN (software-defined wide area network). Combines several internet connections at each site, such as fiber plus a cable or cellular backup, and steers traffic over the best one. It replaces older private circuits between offices and is often built into the same box as the firewall. Managed SD-WAN means the provider configures and watches those links.
• SASE (secure access service edge). Moves firewall, web filtering and secure remote access into a cloud service. Laptops connect to the nearest point of that service, so a user at home or in a hotel gets the same protection as one in the office, and the old VPN can often be retired.
• SASE vs SD-WAN. SD-WAN is about connectivity between places; SASE is about securing users and apps wherever they are. Many SASE products include SD-WAN, and some providers sell them together.

We do not have a reliable, neutral price survey for SD-WAN or SASE, so we do not quote a range here. Pricing is usually per site for SD-WAN and per user for SASE; get at least two written quotes and compare them against what your current firewall and VPN cost. If you are also moving servers to the cloud, review the plan with our cloud migration guide first.

Patch management as part of the managed perimeter

Patch management services keep operating systems, applications and network devices updated on a schedule, and they belong in the same contract as the firewall because unpatched systems are what attackers exploit first. CISA's guidance for small businesses tells IT leads to keep systems patched and remove admin rights from user laptops ⁵.

A managed patching service should spell out:

• Scope. Windows and Mac laptops, servers, third-party apps such as browsers and PDF readers, and firmware on firewalls, switches and Wi-Fi.
• Timing. A normal monthly cycle, plus a faster path for flaws being actively exploited.
• Reporting. Which devices are behind and why, so nothing quietly falls off the list.
• End of life. A plan for systems that no longer receive updates. Windows 10 support ended October 14, 2025; commercial Extended Security Updates cost $61 per device for year one and double each year for up to three years ⁶.

Patching closes known holes; it does not prove the network is secure. A yearly penetration test checks the firewall rules and exposed services from an attacker's point of view, and a cybersecurity risk assessment finds the systems no one is patching.

How to choose a managed firewall provider

Pick a provider that will patch your edge devices quickly, document every change and hand you full control if you leave. Questions to ask:

1. How fast do you apply firmware updates for vulnerabilities that are being actively exploited?
2. Is MFA required on the VPN and on the firewall's own admin login?
3. Who can change rules, how are changes approved, and can we see the change log?
4. Do you forward firewall logs to our MDR or SOC provider?
5. Who owns the hardware, licenses and admin credentials?
6. When does our current firewall reach end of support, and what will replacing it cost?
7. How many rule changes are included each month?
