Reliable and trusted audit partner

I've worked with MHM for five years on SOC 1, SOC 2, and NIST CSF engagements, and they've consistently delivered a great experience. They're highly responsive and easy to work with. Their process is clear, efficient, and reliable—making simultaneous audits across across multiple products feel manageable. I highly recommend them to any organization looking for a trusted audit partner.
Excellent service!

We are a small company who subscribed to Drata a while back, but never really got far for multiple reasons. Getting SOC 2 Type 2 and ISO 27001 certified started to become urgent, and I found MHM a little bit by accident. And what a find! I wish I had found them earlier. They were able to provide me with clear instructions and relevant information to get us throught he process in an impressive timeline. I highly recommend them!
Great teamwork and fast timeline!

MHM rescued us after a bad relationship with our previous auditor who had high turnover and low attention to detail. MHM was not only fast to deliver on their deliverables to get us our report urgently, but they also were very patient with our new analysts and sysadmins to get just the right evidence for our SOC2, Type 2. I will definitely use them in the future and highly recommend them to our friends.
