MSPs as a Cyber Security Risk

Is your MSP a security risk? If your an MSP, do you have cyber security vulnerabilities that put your clients at risk?

It seems like a strange question, right?   We think of the Managed Service Provider (MSP) as part of our cyber security solution, not part of the problem.  And, indeed MSPs are part of your security solution.  But that doesn’t mean we can ignore the cyber security risks of these service providers.  In fact, your MSP may be among the most important suppliers to analyze risk and ensure they are not a vulnerability.  They manage your network.  They have unique IT privileges and access.  If they have a cyber security incident, how does that translate into your cyber security?  

This is increasingly important, as bad actors know that breaching an MSP may be a path into dozens of their clients. Strike once, ransom many. To keep you and your data safe, MSPs need to employ the same or more cyber security plans as you.

A key part of a cyber security plan is the vendor risk management program.  In this program, we assess the vulnerability of our key suppliers to minimize the risk of them being the source of a cyber security breach.  Just as we increasingly see security questionnaires as part of our RFPs, it’s time we apply the same rigor to our MSP.
