MSP stack: which tools MSPs run

PSA, RMM, remote access, documentation, security, backup and distributors seen at the MSPs in the directory: from partner badges, the MSP’s own pages, its job ads and passive public DNS (client-portal hostnames, mail records). Counts are MSPs, not market share. Shares are of the 4,744 MSPs researched in full (3,165 US, 1,579 UK); the other profiles so far had a four-page basic read, which finds fewer tools.
