Best subreddits to find customers for cybersecurity

Security practitioners treat vendor marketing as a threat model — FUD-based pitches get dissected publicly and remembered. What works instead is technical generosity: detection write-ups, honest tooling comparisons, and answers that help someone pass an audit. The community's memory is long in both directions, and MSP subreddits offer a multiplier most vendors miss.

Frequently asked questions

How do security vendors build presence on Reddit?

Through practitioners, not marketers: engineers answering technical questions with disclosure, publishing research, and being honest about product limits. Pipeline follows reputation here, slowly and then suddenly.

Why target r/msp for security sales?

One MSP decision deploys your product across their entire client base, so a single earned recommendation there is worth dozens of end-customer wins.
