Working at the largest retailer in the world, I was constantly on the cusp of the digital revolution—combating the severe cyber risks it introduced, while still enabling the business to harness its transformative power. As a strategic advisor to Semperis, I’m excited to continue this mission by helping companies in the retail sector and beyond to be more cyber resilient so they can embrace the future, not fear it.

Having ADFR at the center of our disaster recovery plan put our mind at ease because now we know that if an incident happens again that takes out the DCs, we have a direct course of action.

Semperis was able to backup and restore AD insanely quickly. During our testing, we were able to back up and restore our Active Directory within 20 minutes to a completely different datacenter with minimal downtime. During a normal backup scenario, that could take 24-36 hours.

Semperis ADFR just gets it done! We went from legacy recovery products full of bugs and manual 20+ page long documents for manual recovery to push a button with ADFR. If you are ready, you click a button, that’s it. It works. Put the 18-pager down, stop dealing with that UI that crashes and check out ADFR. It works.

Today is the first day I’ve used Forest Druid and I’m very impressed. I’ve never found time to learn Bloodhound, so I really appreciate that I just had to run the tool and then click around the GUI to start finding issues.
