MSPs Urged to Rigorously Test Remote Management Tools After Security Concerns

Remote monitoring and management (RMM) platforms, which give managed service providers (MSPs) deep, often privileged, access to client networks, are under heightened scrutiny as cyber‑threats evolve. Industry analysts say that the very capabilities that make RMM attractive—centralized control, automated patching, and real‑time diagnostics—also expand the attack surface if the software itself is not hardened.

A recent guidance document from cybersecurity firm Acronis outlines eight specific controls that MSPs should evaluate before deploying or continuing to use an RMM solution. The checklist ranges from basic patch management practices to more advanced measures such as tenant isolation and reliable recovery mechanisms, reflecting a growing consensus that security must be baked into the tool rather than bolted on later.

First on the list is a robust patching process. RMM vendors must demonstrate that they can quickly apply security updates to their own codebase and that the platform can enforce timely patch deployment across all managed endpoints. Failure to do so leaves a predictable foothold for attackers, who often exploit known vulnerabilities that have been publicly disclosed for months.

Second, the document stresses strict privileged‑access management. Since RMM tools operate with elevated rights, the software should enforce multi‑factor authentication, role‑based access controls, and detailed audit logs that record every administrative action. These logs are essential for forensic investigations and for meeting regulatory requirements in sectors such as healthcare and finance.

Third and fourth controls focus on data integrity and recovery. The platform must provide verifiable backups of configuration data and the ability to restore systems to a known good state after an incident. Acronis points out that without built‑in rollback capabilities, a compromised RMM console could become a vector for widespread ransomware deployment.

Tenant isolation ranks fifth on the checklist. In multi‑tenant environments, a breach in one client’s network should not cascade to others. Effective isolation mechanisms—such as separate cryptographic keys, segmented network paths, and independent logging—prevent cross‑tenant contamination and protect the MSP’s broader reputation.

The final three controls address secure communications, comprehensive logging, and continuous testing. Encrypted channels, immutable logs, and regular penetration testing or red‑team exercises ensure that the RMM platform remains resilient against emerging threats. As MSPs increasingly serve as the back‑office for small and medium‑size businesses, adopting these controls is becoming a competitive differentiator.

Industry observers say the Acronis framework could become a de‑facto standard if adoption spreads. For MSPs, the message is clear: investing in rigorous security validation of RMM tools is no longer optional but a prerequisite for maintaining client trust and safeguarding the broader digital ecosystem.
