I recently built a small project called MSSPProviders.io:
It’s a searchable directory of Managed Security Service Providers (MSSPs).
I originally started compiling this because I kept seeing companies struggle to evaluate security vendors. Most of the information available online is scattered across blog posts, marketing pages, or outdated vendor lists.
The goal of the site is to make the MSSP landscape easier to explore.
Current features:
• ~100 providers indexed • individual provider profiles • browsing by services, industry, supported platforms, and company size • resource articles explaining how MSSPs work and how to evaluate them
I also just published a guide highlighting some of the more established providers in the space:
https://msspproviders.io/resources/top-mssps-in-2026/
The project is built with Next.js + Postgres.
Still early, but I plan to add:
• better provider comparison tools • APIs for security vendor data • more structured research on the MSSP ecosystem
If you work in security or have experience with MSSPs, I’d love feedback on:
1. Which providers should be included 2. What data is most useful when evaluating vendors 3. Whether something like this would benefit from an API
Happy to answer questions.
