“Easy, not easy to work with”
The pre-engagment is a little complex. They are not very flexible with dates or anything else for that matter.
The engamenet and testing is really great. The testers during the years have been on-point, knowledgeable and great.
The draft and final report is always a challenge to get. Although the company has been notified of our payment workflow, there is always a hiccup here or there to get it to the finish line.
The post engamenent is smooth. They are flexible and fast to start the engamenet for the next year. Not very flexible with pricing.
At this point, there are cheaper and easier vendors to work with.

Experiencing a Strategic Partnership with Schellman
Schellman is a true partner in every sense of the word. They work closely with us on the required parts of assessments and certifications, and this is always solid and effective (as enjoyable as compliance work can be :)). But more importantly, they help us set strategy, providing expert feedback and advice on emerging standards and marketplace changes. Whether bread-and-butter ISO 27001 certifications and Type 2 SOC 2 examinations, or additional services such as NIST SP 800-171 / CMMC, or looking ahead to our possible work towards FedRAMP or ISO 42001, they are always happy to work with us to not only do the work, but also ensure that we do the right work at the right time. A genuine pleasure to work with. - CHIEF INFORMATION SECURITY OFFICER10B+ USDBankingReview Source
