What We Cover
Independent MSSP rankings for US businesses
Cybersecurity has its own provider category — and its own research challenges. Here’s how we evaluate MSSPs differently from general MSPs, and what the Trust Score captures in the security space.
A managed security service provider (MSSP) delivers outsourced cybersecurity operations — 24/7 threat monitoring, detection and response, vulnerability management, compliance frameworks, and security operations center (SOC) functions. For most mid-market companies, building those capabilities in-house costs $2M–$5M annually in headcount and tooling alone. An MSSP replaces that with a recurring engagement.
The MSSP market is crowded and hard to evaluate. Every provider claims 24/7 SOC coverage, AI-driven detection, and “proactive” threat hunting. What actually differentiates them is analyst depth, platform architecture, incident response speed, and the certifications that prove their controls are real — not self-reported. That’s what the Trust Score captures.
For cybersecurity rankings, we weight review data from Clutch, G2, and Gartner Peer Insights; award recognition from Gartner Magic Quadrant, Forrester Wave, and industry publications; years of operation; US headquarters and SOC footprint; security-specific certifications (SOC 2 Type II, ISO 27001, FedRAMP); and service breadth across MDR, XDR, SIEM, vulnerability management, and incident response.

How MSSP Rankings Work
The Trust Score: adapted for security providers
The same six-factor Trust Score framework used for MSP rankings applies here, with the data sources adapted for the security market. Review weight draws from Clutch, G2, and Gartner Peer Insights. Awards include Gartner Magic Quadrant, Forrester Wave, and MSSP Alert Top 250. Specialization credit is awarded for named certifications — SOC 2 Type II, ISO 27001, FedRAMP — not claims on a landing page.
Security Provider Types
Which type of security provider do you need?
MSSP, MDR, and SOCaaS are often used interchangeably — but they describe meaningfully different service architectures. Here’s how to tell them apart.
Broad security operations outsourcing — 24/7 SOC monitoring, SIEM management, threat detection, vulnerability management, and compliance reporting. MSSPs take over ongoing security operations so your team focuses on business risk, not alert triage.
● Rankings live — 7 national providersA focused subset of MSSP services — real-time threat detection, investigation, and active response across endpoints, network, and cloud. MDR providers typically go further than monitoring: they contain and neutralize threats, not just escalate alerts.
● Covered in MSSP rankingsDelivers a fully outsourced security operations center — staffed analysts, SIEM platform, and playbooks — without the capital cost of building one internally. Best for mid-market companies that need 24/7 coverage but can’t justify a dedicated in-house team.
● Covered in MSSP rankingsProvides fractional Chief Information Security Officer leadership — security strategy, risk management, board reporting, and program oversight. Often bundled with MSSP services for mid-market companies that need executive-level security leadership without a full-time hire.
