Palo Alto Networks scores highest in our 2026 evaluation of managed firewall service, with Fortinet close behind on breadth and value and Cato Networks leading on cloud-native delivery.
A managed firewall service transfers day-to-day firewall operation policy changes, patching, monitoring, tuning, and incident response to a provider with a 24/7 SOC, so your team stops doing 2 a.m. rule changes.
Here are the ten best, scored, with the ownership changes you must factor into a multi-year contract.
The 2026 Managed Firewall Scorecard

Weighted averages rounded to one decimal. Rank reflects overall buyer fit including market-position considerations noted below, not score alone.
How We Scored
A structured research-based evaluation, not a comparative service test we have not run parallel engagements and don’t claim to have. Criteria reflect what actually determines whether a managed firewall engagement succeeds:
• SOC and response (30%) — analyst quality, 24/7 coverage, documented response SLAs, escalation, and threat intelligence feeding detection.
• Platform coverage (25%) — which firewall vendors the provider will manage, and whether they support your existing hardware or require a rip-and-replace.
• Service model (20%) — fully managed versus co-managed, change request turnaround, portal transparency, and whether you retain visibility and control.
• Global reach (15%) — geographic coverage, local language support, and data residency.
• Value (10%) — total cost versus in-house operation, and contract flexibility.
Two Ownership Changes Every Buyer Should Check
Managed security contracts run three to five years. Two market events materially affect this list, and both are frequently reported incorrectly elsewhere:
Secureworks is now part of Sophos.Sophos completed its acquisition of Secureworks in February 2025 in a transaction valued at approximately $859 million.
Secureworks’ Taegis platform and Counter Threat Unit intelligence remain genuine assets, but the service portfolio now sits inside Sophos’ MDR business.
Ask directly how your specific service maps to the combined portfolio and what the long-term product roadmap is.
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. A number of comparison articles still describe this merger as completed it was not.
Trustwave’s SpiderLabs research and managed security operations remain intact, and it should be evaluated as an independent provider.
Beyond those two: LevelBlue is the rebranded AT&T Cybersecurity business, now independent and actively acquiring, and Comcast Business absorbed Masergy’s managed network security portfolio. Confirm current service naming and the support entity on your contract in every case.
The 10 Best Managed Firewall Services, Scored
1. Palo Alto Networks — Score 8.6/10
Why it scores here: The strongest combination of platform quality and service maturity. Palo Alto’s managed services and Unit 42 incident response give you best-in-class next-generation firewall (NGFW) technology operated by people who see attacks across a very large customer base.
Strengths: deep expertise on the platform being managed (nobody knows PA firewalls better); Unit 42 threat intelligence and IR retainer options; consistent management across on-prem NGFW, Prisma Access, and cloud; strong automation reducing change latency.
Trade-offs: you’re committing to Palo Alto as your firewall platform, not just a service; premium pricing at both layers; less appealing if you want a vendor-neutral operator.
Ideal buyer: enterprises standardizing on Palo Alto that want the vendor to run it.
Verify before buying: exact SLA terms for change requests and incident response in your region.

2. Secureworks — Score 8.6/10
Why it scores here: the highest SOC score in the list. Secureworks’ Counter Threat Unit (CTU) research and Taegis platform have set the standard for managed detection quality for two decades, and its firewall management inherits that analytic depth.
Strengths: exceptional threat research and detection engineering; strong multi-vendor firewall management; transparent customer portal; mature co-managed model where your team keeps visibility.
Trade-offs: now inside Sophos following the February 2025 acquisition (~$859M) portfolio positioning within the combined Sophos MDR business is a fair and necessary question; pricing above commodity providers.
Ideal buyer: organizations prioritizing detection and response quality over lowest cost.
Verify before buying: how your service maps to the post-acquisition Sophos portfolio and the roadmap commitment for it.

3. LevelBlue (AT&T) — Score 8.6/10
Why it scores here: strong across every dimension, with genuine scale. LevelBlue the former AT&T Cybersecurity, now operating independently combines a global SOC footprint with broad multi-vendor firewall management and Open Threat Exchange intelligence.
Strengths: manages most major firewall platforms rather than pushing one; large global SOC presence; strong consulting alongside managed services; OTX community threat intelligence.
Trade-offs: the business has been through rebranding and acquisition activity confirm the contracting entity and service continuity; service consistency can vary by region and delivery centre.
Ideal buyer: large multinationals with heterogeneous firewall estates wanting one operator.
Verify before buying: current entity name on contract, regional delivery centres, and service naming.

4. Fortinet — Score 8.5/10
Why it scores here: best value with the broadest platform coverage. Fortinet’s managed and co-managed offerings, delivered directly and through a very large partner ecosystem, bring FortiGate operations under 24/7 management at price points below the premium providers.
Strengths: excellent price-performance; huge partner delivery network offering local options; full Security Fabric management including switching, wireless, and endpoint; FortiGuard threat intelligence.
Trade-offs: Quality varies significantly across the partner ecosystem — vet the actual delivery partner, not just the brand; Fortinet’s exploited-vulnerability record makes adhering to CISA Known Exploited Vulnerabilities guidance and patch SLA language a critical contract term.
Ideal buyer: cost-conscious organizations on Fortinet wanting managed operations, and mid-market buyers.
Verify before buying: who actually delivers the service, and the contractual patching SLA for critical vulnerabilities.

5. Cato Networks — Score 8.4/10
Why it scores here: the cleanest cloud-native model. Cato’s firewall is a function of its global Secure Access Service Edge (SASE)
backbone rather than an appliance someone manages for you which removes hardware refresh, patching, and capacity planning entirely.
Strengths: no appliances to manage, patch, or refresh; consistent policy for sites, cloud, and remote users; genuinely simple operations; strong for distributed organizations replacing MPLS.
Trade-offs: you’re adopting Cato’s platform, not having your existing firewalls managed; less appropriate for organizations with heavy on-prem inspection requirements or existing hardware investment; single-vendor dependency.
Ideal buyer: distributed enterprises consolidating networking and security into one cloud platform.
Verify before buying: PoP coverage in your operating regions and throughput commitments.

6. NTT Data — Score 8.4/10
Why it scores here: the strongest global reach in the list. NTT operates one of the world’s largest managed security footprints with genuine local delivery in Asia-Pacific, Europe, and the Americas, plus its own global network infrastructure.
Strengths: Unmatched geographic coverage with local-language SOC delivery; broad multi-vendor platform support; strong data residency options; deep systems-integration capability alongside managed detection and response (MDR) services.
Trade-offs: large-organization procurement and account management overhead; service experience varies by delivery region; pricing suits enterprise scale rather than mid-market.
Ideal buyer: multinationals with operations across multiple continents and data residency requirements.
Verify before buying: which regional entity delivers your service and the local SOC’s hours and languages.

8. Verizon — Score 7.8/10
Why it scores here: Enormous global reach and network integration, marked down on service-model flexibility. Verizon’s managed firewall sits alongside its network services, delivering protection backed by insights from its authoritative cloud security solutions and annual DBIR research.
Strengths: global network footprint and integrated connectivity plus security; long-standing enterprise relationships; well-known Data Breach Investigations Report research capability; strong for regulated industries.
Trade-offs: less flexible and slower-moving than specialist providers; change request turnaround is a common complaint in large carrier engagements — press hard on SLA specifics; pricing reflects carrier economics.
Ideal buyer: enterprises already buying Verizon connectivity wanting a single supplier.
Verify before buying: documented change-request turnaround SLAs with credits attached.

9. GTT — Score 7.6/10
Why it scores here: Good value with genuine global network reach, particularly for organizations wanting managed SD-WAN and firewall from one provider as a modern alternative to traditional business VPN solutions.
Strengths: integrated managed SD-WAN plus security services; competitive pricing; broad international coverage; flexible service wraps around multiple security vendors.
Trade-offs: SOC depth trails the security-specialist providers; GTT has been through significant financial restructuring in recent years, so confirm current stability and service commitments; better suited to network-led than security-led buyers.
Ideal buyer: organizations procuring managed network and security together across international sites.
Verify before buying: current corporate and financial position, and security service depth versus network services.

10. Comcast Business (Masergy) — Score 7.3/10
Why it scores here: solid managed security capability inherited from Masergy, delivered with strong value, but with narrower global reach than the carriers above.
Strengths: Masergy’s managed security heritage is genuine, including detection and response capability alongside endpoint management integration; good integration with managed SD-WAN; competitive pricing; strong US presence and support.
Trade-offs: international coverage is thinner than NTT, Verizon, or GTT; Masergy branding has been absorbed into Comcast Business, so confirm current service naming and continuity; enterprise security depth trails the specialists.
Ideal buyer: US-centric mid-market and enterprise organizations wanting managed network plus security from one provider.
Verify before buying: current service naming, international coverage, and SOC location.

Head-to-Head: The Comparisons That Decide It
Vendor-managed vs independent MSSP. Palo Alto, Fortinet, and Cato manage their own platforms deepest possible product expertise, but you’re locked to their technology.
Secureworks, LevelBlue, Trustwave, and NTT manage multiple vendors more flexibility and honest platform advice, slightly less product depth. If you’re standardized and happy, go vendor-managed.
If your estate is mixed or you want independent counsel, go MSSP.
Carrier vs security specialist. Verizon, GTT, NTT, and Comcast bundle connectivity with security, which simplifies procurement and often improves commercials. Security specialists deliver better SOC quality and faster change turnaround. Carrier engagements live or die on the change-request SLA — get it in writing with credits.
Managed appliances vs cloud-native. Cato eliminates hardware entirely; everyone else manages devices you own or lease. The cloud-native model removes refresh cycles and patching risk but requires adopting a platform.
Organizations with recent hardware investment or heavy on-prem inspection needs usually aren’t ready for it yet.
How to Buy Managed Firewall Services Well
Define fully managed versus co-managed before you talk to anyone. Fully managed means the provider owns all changes; co-managed means your team retains console access and can act.
Co-managed usually works better for organizations with in-house skills who want coverage rather than replacement and it’s a very different contract.
Make change-request SLA the headline commercial term. The single most common source of managed firewall dissatisfaction is slow change turnaround. Specify tiers (emergency, standard, project), turnaround times, and service credits. A provider unwilling to attach credits is telling you something.
Nail down patching responsibility explicitly. Given the volume of exploited firewall vulnerabilities in recent years including CISA emergency directive activity around edge devices the contract must state who patches, within what window of vendor release, and what happens during zero-day events. This is now the most important operational clause in the agreement.
Insist on transparency and exit. You need read access to policy, logs, and change history throughout, plus a documented offboarding process returning full configurations. Providers who make policy opaque create switching costs by design.
Confirm who actually delivers the service. Especially with Fortinet’s partner-delivered model and the carriers’ regional structures, the logo on the contract may not be the team answering at 3 a.m.
Ask for the SOC location, staffing model, and escalation path and reference customers in your region.
Common mistakes: buying managed firewall without also addressing network detection and response so you have perimeter management but no internal visibility; signing multi-year terms without exit provisions; and shortlisting from articles that haven’t tracked the ownership changes above.
Frequently Asked Questions
What is a managed firewall service?
A managed firewall service outsources day-to-day firewall operation to a provider with a 24/7 security operations centre including policy configuration and changes, firmware patching, monitoring, log analysis, tuning, and incident response.
It can be fully managed, where the provider owns all changes, or co-managed, where your team retains access and shares responsibility.
Which is the best managed firewall service in 2026?
Palo Alto Networks, Secureworks, and LevelBlue score highest overall for different reasons: Palo Alto for platform expertise on its own NGFWs, Secureworks for SOC and detection quality, and LevelBlue for multi-vendor management at global scale.
Fortinet offers the best value and Cato Networks the cleanest cloud-native model.
Is Secureworks still independent?
No. Sophos completed its acquisition of Secureworks in February 2025 in a transaction valued at approximately $859 million.
Secureworks’ 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.
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.
How much do managed firewall services cost?
Managed firewall pricing is quote-based and typically structured per device or per site per month, with tiering by firewall model, throughput, and service level.
Expect meaningful variance between carrier-bundled and specialist providers; specialists generally cost more and deliver faster change turnaround. Compare against fully loaded in-house cost including 24/7 coverage.
Fully managed or co-managed — which is better?
Co-managed suits organizations with in-house security staff who need 24/7 coverage and escalation while retaining control and visibility. Fully managed suits teams without firewall expertise or after-hours capacity.
Co-managed usually preserves more institutional knowledge and makes provider changes easier later.
Bottom Line
Palo Alto Networks, Secureworks, and LevelBlue lead this list, and the choice among them comes down to whether you value platform-native expertise, SOC and detection quality, or multi-vendor flexibility at global scale.
Fortinet remains the value leader if you vet the delivery partner properly, and Cato is the right answer for distributed organizations ready to leave appliances behind.
Whichever you pick, the contract matters more than the scorecard: get change-request SLAs with credits, explicit patching windows, full policy transparency, and a clean exit and verify current ownership, because two of the biggest names on this list changed materially in 2025.
