Even security-conscious MSPs may expose their RMM environment with minor flaws that hackers are eager to take advantage of. Here are a few of the most typical mistakes and how to avoid them.
• On-premise complacency: Self-hosted RMMs may not keep up with updates, particularly if patching could cause service interruptions. By scheduling regular update periods, testing patches in staging, and implementing them as soon as vendor advisories are released—especially if a vulnerability is in the CISA KEV catalogue—you may treat RMM and PSA software patching as urgent maintenance rather than a "when convenient" chore.
• Weak Multifactor authentication: Without robust multifactor authentication, critical theft is considerably easier, opening the way for your former clients. Using phishing-resistant solutions, such as hardware security keys or FIDO2 tokens, and disabling legacy authentication methods that circumvent MFA, make MFA required for all RMM logins.
