The 12 Best Managed Firewall Services, Compared and Priced

Best value overall: Fortinet. Delivered directly and through the largest partner network in security, at price points the premium providers can’t approach provided you vet the actual delivery partner.

Best detection quality: Secureworks.

Best global reach: NTT Data.

Best if you want to stop owning firewalls: Cato Networks.

Best for SMB: Barracuda MSP.

Managed firewall is the one security category where the contract matters more than the provider.

Evaluating outsourced firewall management requires looking closely at what these services cost, what to put in the agreement, and two major ownership changes that are widely misreported across the industry.

Stage 1 — Check the Two Ownership Changes First

Managed security contracts run three to five years. Get these wrong and you’re locked into a relationship you didn’t evaluate.

Secureworks is now part of Sophos. Sophos completed the acquisition in February 2025, in a transaction valued at approximately $859 million.

The Taegis platform and Counter Threat Unit research remain genuine assets, but the service portfolio now sits inside Sophos’ managed detection and response business.

Ask directly how your specific service maps to the combined portfolio and what roadmap commitment exists.

The Trustwave–Cybereason merger was cancelled. It was announced, then terminated on 10 March 2025. Trustwave continues to operate independently under MC² Security Fund ownership with SpiderLabs research intact.

A significant number of comparison articles still describe this merger as completed it was not, and Trustwave should be evaluated as an independent provider.

Also worth confirming: LevelBlue is the rebranded AT&T Cybersecurity business, now operating independently; Comcast Business absorbed Masergy’s managed security portfolio. In both cases, confirm the current service naming and the legal entity on your contract.

Stage 2 — Understand What Managed Firewall Actually Costs

Everything here is quote-based. No provider publishes managed firewall pricing, because it varies by device count, firewall model, throughput, service tier, and region. Treat any specific figure you find online without a source as unreliable.

The standard structure is per device or per site, per month. Expect tiering by firewall model and throughput, with additional charges for higher service levels, faster change turnaround, and log retention beyond a baseline period.

Four cost tiers, roughly:

Tier	Who’s in it	What drives the price
Premium specialists	Secureworks, Trustwave, Palo Alto	SOC quality, research depth, fast change SLAs
Carriers	Verizon, GTT, Comcast Business	Bundled with connectivity; slower, cheaper
Global integrators	NTT Data, TCS, LevelBlue	Scale economics; delivery-centre dependent
Value / platform	Fortinet, Barracuda MSP, Cato	Lowest cost; partner or platform delivered

Compare against fully loaded in-house cost, not headcount. 24/7 coverage requires roughly five to six full-time engineers to staff properly, plus tooling, plus holiday and sickness cover. Most organizations comparing a managed service against “one firewall admin” are comparing against something that doesn’t actually provide 24/7 coverage.

Log retention is a hidden line item. Compliance frameworks often require 12 months or more. Ask what’s included in the base price and what extended retention costs — this surprises buyers regularly.

Stage 3 — The Twelve Providers

Value and platform-delivered

Fortinet

managed and co-managed FortiGate operations, delivered directly and through one of the largest partner networks in security. Full Security Fabric management covering switching, wireless, and endpoint alongside firewalls.

Cost profile: lowest in this list for comparable scope.

Watch for: Quality varies significantly across the partner ecosystem vet the actual delivery partner, not the brand.

Fortinet’s exploited-vulnerability record, including a FortiCloud authentication bypass added to CISA’s Known Exploited Vulnerabilities catalog, makes addressing Fortinet zero-day vulnerabilities through strict patching clauses critical.

Barracuda MSP

Managed security delivered through a mature MSP channel, built specifically for smaller organizations and the providers who serve them, delivering tailored solutions alongside top managed security service providers (MSSPs).

Cost profile: the most accessible tier here for small business.

Watch for: enterprise depth and global SOC scale trail the specialists; you’re buying through an MSP, so the MSP is your actual provider.

Cato Networks

Managed security delivered through a mature MSP channel, built specifically for smaller organizations and the providers who serve them, delivering tailored solutions alongside top managed security service providers (MSSPs).

Cost profile: subscription covering network and security together; often competitive against MPLS plus managed firewall.

Watch for: you’re adopting Cato’s platform, not having your existing firewalls managed; poor fit if you’ve just invested in hardware.

Premium specialists

Secureworks

Two decades of Counter Threat Unit research applied to firewall management, with genuine transparency through the Taegis portal and real multi-vendor support from a leader in managed detection and response (MDR).

Cost profile: premium tier.

Watch for: now inside Sophos following the February 2025 acquisition portfolio positioning is a necessary question before a multi-year commitment.

Arctic Wolf

24×7 managed detection and response with security monitoring across networks, endpoints, and cloud environments, backed by Arctic Wolf’s Concierge Security Team and threat intelligence capabilities.

Cost profile: premium managed-security tier; pricing is typically quote-based.

Watch for: Arctic Wolf is primarily an MDR and security-operations provider rather than a dedicated managed-firewall specialist.

Confirm which firewall platforms and management actions are included in the specific service scope before positioning it as a direct Trustwave replacement.

Arctic Wolf supports integrations with multiple firewall platforms, including Fortinet, Palo Alto Networks, Juniper, SonicWall, Sophos, and WatchGuard.

Palo Alto Networks

The vendor who built your firewall also runs it, with Unit 42 threat intelligence and incident response available alongside their next-generation firewall (NGFW) platforms.

Cost profile: premium at both product and service layers.

Watch for: commits you to Palo Alto as a platform, not just as a provider; not the choice if you want vendor-neutral advice.

Global integrators

NTT Data

One of the largest managed security footprints globally, with genuine local delivery across Asia-Pacific, Europe, and the Americas plus its own network infrastructure and comprehensive network security operations.

Cost profile: enterprise scale economics; suits large deployments.

Watch for: service experience varies by delivery region confirm which regional entity delivers your service and the local SOC’s hours and languages.

LevelBlue (AT&T)

The former AT&T Cybersecurity, now independent, combining a global SOC footprint with broad multi-vendor firewall management and AlienVault USM threat intelligence, backed by cloud-delivered threat detection.

Cost profile: mid-to-premium, competitive at scale.

Watch for: rebranding and acquisition activity means you should confirm the contracting entity and service continuity.

TCS

Managed network and firewall services delivered through Tata Consultancy Services’ cybersecurity practice, typically as part of a broader managed IT and business network infrastructure engagement.

Cost profile: competitive integrator economics, usually within a larger services agreement.

Watch for: security is one practice within a very large services organization the assigned delivery team matters far more than the brand; procurement overhead suits enterprise scale.

Carriers

Verizon

Managed firewall alongside the network circuits you may already buy, with global reach, long-standing enterprise relationships, and actionable threat research capabilities.

Cost profile: carrier economics; often bundled favourably with connectivity.

Watch for: change-request turnaround is a recurring complaint in large carrier engagements press hard on SLA specifics and insist on service credits.

GTT

Integrated managed SD-WAN and security services with broad international coverage at competitive pricing, providing an alternative to traditional business VPN solutions.

Cost profile: value tier among the carriers.

Watch for: SOC depth trails the security specialists; GTT has been through significant financial restructuring in recent years, so confirm current stability and service commitments.

Comcast Business (Masergy)

Managed security capability inherited from Masergy, with good value and strong US presence alongside managed SD-WAN and integrated CASB cloud security controls.

Cost profile: competitive for US-centric deployments.

Watch for: international coverage is thinner than NTT, Verizon, or GTT; Masergy branding has been absorbed, so confirm current service naming.

Stage 4 — Write the Contract That Actually Protects You

This is where managed firewall engagements succeed or fail, and it matters more than which logo you picked.

Make the patching clause explicit. Who patches, within what window of vendor release, and what happens during a zero-day. Given how frequently firewall and network edge devices appear in exploited-vulnerability advisories and national cyber agency directives, this is now the single most consequential operational term in the agreement. Specify hours, not “promptly.”

Attach service credits to change-request SLAs. Define emergency, standard, and project tiers with turnaround times and credits for missing them. Slow change turnaround is the most common source of dissatisfaction in this category, and a provider unwilling to attach credits is telling you what to expect.

Define fully managed versus co-managed precisely. Fully managed means the provider owns every change. Co-managed means your team retains console access and can act. Co-managed usually works better for organizations with in-house skills, and it’s a materially different contract not a checkbox.

Demand transparency and a clean exit. Read access to policy, logs, and change history throughout, plus a documented offboarding process returning complete configurations in a usable format. Providers who keep policy opaque are manufacturing switching costs by design.

Name the delivery team, not just the brand. SOC location, staffing model, escalation path, language coverage, and reference customers in your region. With partner-delivered and integrator models especially, the logo on the contract is often not the team answering at 3 a.m.

Specify log retention and data residency. How long, where, in what format, and what it costs to extend. Compliance frameworks frequently require more than the base offering includes.

Stage 5 — Compare Quotes Fairly

Normalize the scope. Same device count, same models, same service tier, same change volume assumption, same log retention period. Managed service quotes are unusually easy to compare unfairly.

Ask for the change volume assumption in writing. Most contracts include a number of changes per month, with overage charges beyond it. Estimate your real change volume from the last twelve months rather than accepting the provider’s assumption.

Price the exit before you sign the entry. Offboarding assistance, configuration export format, and any transition fees. This has more effect on your negotiating position in year three than anything else in the contract.

Test the response process during evaluation. Ask each shortlisted provider to walk through a real scenario: a critical vulnerability announced at 2 a.m. on a Saturday. The quality of the answer tells you more than the SLA document.

Common mistakes: buying managed firewall with no internal visibility, so you have a managed perimeter and no network security monitoring behind it; signing multi-year terms without exit provisions; and shortlisting from articles that report the Trustwave merger as completed.

Cost-Focused FAQ

How much do managed firewall services cost?

All providers are quote-based, typically structured per device or per site per month, tiered by firewall model, throughput, and service level.

Carrier-bundled and integrator-delivered options generally cost less than premium security specialists, which deliver faster change turnaround and deeper SOC capability.

Compare against fully loaded in-house cost including genuine 24/7 coverage.

Which managed firewall service is cheapest?

Fortinet-delivered services, either direct or through partners, are generally the lowest cost for comparable scope, and Barracuda MSP is the most accessible for small businesses.

Carrier options bundled with connectivity you already buy can also be very competitive. The trade-off in every case is SOC depth and change-request speed.

Is Secureworks still independent?

No. Sophos completed its acquisition of Secureworks in February 2025 in a transaction valued at approximately $859 million.

The Taegis platform and Counter Threat Unit remain, but the service portfolio now sits within Sophos. Ask how your specific service maps to the combined roadmap before committing to a multi-year term.

Did Trustwave merge with Cybereason?

No. The announced merger was terminated on 10 March 2025 and Trustwave continues to operate independently under MC² Security Fund ownership, with SpiderLabs research intact.

Several comparison articles still describe the merger as completed, which is incorrect.

Is managed firewall cheaper than hiring in-house?

Usually yes, if you genuinely need 24/7 coverage. Staffing a round-the-clock rota properly requires roughly five to six engineers plus tooling and cover, which exceeds most managed firewall contracts.

For business-hours-only coverage of a small estate, in-house is often cheaper and co-managed services exist precisely to cover the gap.

What should be in a managed firewall SLA?

At minimum: change-request turnaround by tier with service credits attached, patching windows for critical vulnerabilities with a defined zero-day process, incident response and escalation times, availability commitments, reporting cadence, log retention terms, and offboarding provisions returning full configurations. Get the SOC location and language coverage documented too.

Bottom Line

Fortinet delivers the best economics for most organizations, provided you evaluate the delivery partner as carefully as the brand.

Secureworks and Trustwave are worth their premium when detection quality drives the decision and both need an ownership conversation before you sign.

NTT Data and TCS make sense inside larger managed IT relationships, the carriers when you already buy their connectivity, and Cato if you’d genuinely rather stop owning firewalls at all.

But spend your energy on the contract rather than the shortlist: patching windows in hours, change SLAs with credits, named delivery teams, and a clean exit are what determine whether this works.
