MSSP Directory: Compare Managed Security Service Providers
This directory lists managed security service providers (MSSPs), the companies that run security monitoring, threat detection, and incident response for organizations without a full in-house security operations center. Filter the full list by service, industry, company size, and security platform to narrow it into a shortlist you can compare side by side.
Compare managed security service providers. Use filters to narrow your search. The directory covers providers across all major service categories (MDR, SIEM management, vulnerability scanning, incident response, and more) as well as a wide range of industries and security platforms. Use the filter sidebar to narrow results by the criteria that matter most to your organization, and combine multiple filters to zero in on the right shortlist. Each provider profile includes service details, certifications, platform expertise, and key operational facts so you can compare options without leaving the page. New to MSSPs?

How to Use This Directory
Start with the directory results below and open provider profiles to compare services, platforms, industries, and company fit. If you already know what capabilities you need, use the service filters (MDR, SIEM, vulnerability scanning, etc.) to see only providers that offer those services. If compliance is your primary concern, try the industry filters to find providers experienced with your sector's regulatory requirements (healthcare, finance, government, and more). If you need an MSSP that integrates with your existing security tools, use the platform filters to surface providers with verified expertise on platforms like CrowdStrike, Microsoft Sentinel, Palo Alto, or SentinelOne.
