• Platform coverage (25%): Examines the range of firewall vendors supported by the provider and whether they accommodate existing hardware or necessitate a complete replacement.
• Service model (20%): Considers options like fully managed versus co-managed, efficiency of change request fulfillment, transparency of client portals, and the degree to which clients maintain visibility and control.
• Global reach (15%): Evaluates geographic coverage, multilingual support capabilities, and adherence to data residency regulations.
• Value (10%): Compares the total cost of the service against in-house operations and assesses contractual flexibility.

Two Ownership Changes Every Buyer Should Check

Managed security contracts typically span three to five years, making it imperative for buyers to be aware of recent market shifts. Two significant developments have materially impacted this list, often misreported elsewhere:

Secureworks is now part of Sophos.

Sophos finalized its acquisition of Secureworks in February 2025, a deal valued at approximately $859 million. While Secureworks’ Taegis platform and Counter Threat Unit intelligence remain valuable assets, their service portfolio is now integrated into Sophos’s Managed Detection and Response (MDR) business. Prospective clients should directly inquire about how their specific service needs align with the consolidated portfolio and the long-term product roadmap.

The Trustwave–Cybereason merger was cancelled.

Despite earlier announcements, the planned merger between Trustwave and Cybereason was officially terminated on March 10, 2025. Trustwave continues to operate independently under the ownership of MC² Security Fund. Several comparative analyses still incorrectly state this merger as completed. Trustwave’s SpiderLabs research and managed security operations remain fully intact, and the company should be evaluated as a standalone provider.

Additionally, LevelBlue (AT&T) — Score 8.6/10 is the rebranded AT&T Cybersecurity division, now operating as an independent entity and actively pursuing acquisitions. Comcast Business (Masergy) — Score 7.3/10 has integrated Masergy’s managed network security offerings. It is crucial for buyers to verify the current service names and the specific support entity listed in any contract.

Head-to-Head: The Comparisons That Decide It

Vendor-managed vs. Independent MSSP

Providers like Palo Alto Networks, Fortinet, and Cato Networks directly manage their own platforms, offering unparalleled product expertise but locking clients into their specific technologies. In contrast, Secureworks, LevelBlue, and NTT manage multiple vendor platforms, providing greater flexibility and unbiased platform advice, though with slightly less product-specific depth. If your organization is standardized and content with a single vendor, a vendor-managed approach is suitable. For mixed estates or a desire for independent counsel, an MSSP is preferable.

Carrier vs. Security Specialist

Carriers such as Verizon, GTT, NTT, and Comcast bundle connectivity with security services, which can streamline procurement and often result in more favorable commercial terms. However, dedicated security specialists typically offer superior SOC quality and faster change turnaround times. The success of carrier engagements often hinges on the change-request SLA; ensure this is explicitly documented with associated credits.

Managed Appliances vs. Cloud-Native

Cato Networks epitomizes the cloud-native model by entirely eliminating hardware, thereby removing refresh cycles and patching risks. Other providers primarily manage physical or virtual appliances. While cloud-native solutions simplify operations, they necessitate platform adoption. Organizations with recent hardware investments or significant on-premise inspection requirements may find cloud-native solutions less immediately suitable.

How to Buy Managed Firewall Services Well

To ensure a successful managed firewall engagement, consider the following practical steps:

• Define fully managed vs. co-managed roles: Before engaging vendors, clarify whether you need the provider to handle all changes (fully managed) or if your team will retain console access and share responsibilities (co-managed). The latter is often better for organizations with in-house skills seeking augmented coverage.
• Prioritize change-request SLAs: Slow change turnaround is a primary source of dissatisfaction. Insist on explicit SLA tiers (e.g., emergency, standard, project), specific turnaround times, and service credits for non-compliance. A provider’s reluctance to offer credits is a significant red flag.
• Clarify patching responsibilities: Given the frequency of exploited firewall vulnerabilities and CISA emergency directives, the contract must clearly state who is responsible for patching, the response window post-vendor release, and procedures for zero-day events. This is a critical operational clause.
• Demand transparency and exit provisions: Ensure you have read access to policy configurations, logs, and change history throughout the contract term. A documented offboarding process that returns full configurations is essential to avoid vendor lock-in and facilitate future transitions.
• Confirm the actual service delivery entity: Especially with partner-driven models (like Fortinet’s) and carrier regional structures, the name on the contract may not be the team providing 3 AM support. Ask for SOC locations, staffing models, escalation paths, and regional customer references.

Common mistakes to avoid: Purchasing managed firewall services without also addressing network detection and response, leading to perimeter security without internal visibility; signing multi-year contracts without clear exit provisions; and relying on outdated comparison articles that fail to account for recent ownership changes.

What You Should Do

• Review existing contracts: If you are currently under contract with Secureworks or LevelBlue (formerly AT&T Cybersecurity), verify the current service provider entity and understand how recent acquisitions or rebranding efforts impact your service delivery and future roadmap.
• Negotiate SLAs rigorously: For any new or renewed managed firewall service, prioritize detailed Service Level Agreements (SLAs) for change requests and patching. Ensure these include specific timeframes and penalties (service credits) for non-compliance.
• Demand transparency: Insist on full access to your firewall policies, logs, and change history. This ensures you maintain visibility and control, and simplifies potential transitions to other providers.
• Verify delivery teams: Always confirm the actual SOC location, staffing model, and escalation procedures of the team that will be managing your firewalls, especially for providers leveraging partner networks or regional operations.
• Integrate broader security strategy: Do not treat managed firewall services in isolation. Ensure they align with and complement your overall network detection and response strategy to provide comprehensive security visibility.
