Midmarket organizations "don't have the time to manage … or deploy a SIEM [tool]. But a managed SIEM offering where you might have the technology in place or you might have a managed version of that that somebody else is managing for you" can be a good way to call on an MSSP, Reed said.

One of Proficio's chief offerings is a cloud-based SIEM, which Thompson said benefits midmarket companies because its annual cost is only about one-fifth that of a SIEM tool.

The midmarket "is perfect" for Proficio because SIEM is expensive and Proficio can reduce the costs for the organization, he said.
