We use red seal for all our security audits (including PCI-DS) at multiple levels of my organization - including data center/cloud environments as well as end user desktop devices in various locations around campus across several states! It's quick turnaround time is amazing which allows us keep up with constantly evolving regulations & requirements that we have coming down each day, often within minutes or hours after an event occurs!! Nothing really but minor nitpicks about how it could be more intuitive / easier to navigate through when you're looking into your audit results by specific areas vs having them listed alphabetically under general sections such has "Data Center" etc.. I think they've taken this approach so users can see what was found immediately upon opening rather than going back thru every single section one item per page like most other software would do...but maybe thats just me?? Overall great product if used properly! Security team uses these tools daily along side manual methodologies during.
