Why MSP Security Matters More Than Ever

In 2026, MSPs are the #1 target for cybercriminals. Compromising one MSP gives attackers access to dozens or hundreds of downstream clients.

Top 5 Threats Facing MSPs

  1. Ransomware-as-a-Service (RaaS) — Average ransom demand for MSP clients has reached $4.5 million.
  2. Supply Chain Attacks — Attackers target MSP tools (RMM, PSA, remote access) to pivot into client environments.
  3. Credential Stuffing — Reused passwords across environments. One compromised credential can cascade across your entire book of business.
  4. Business Email Compromise (BEC) — Social engineering targeting MSP staff.
  5. Insider Threats — Disgruntled employees with privileged access to multiple clients.
