I've been reading about the healthcare industry being held hostage by Ransomware caused by these "spear" phishing attacks. This is a frightening prospect, knowing that one accidental click on a link can put me out of business. There isn't anyone else I would even consider using for something as sensitive as this. Cardinal came in to speak to everyone on staff, educate them on what to look out for and check all our technology and business tools for leaks that could let someone do this to us. The most impressive thing, to me, is that the attention did not end when I paid the bill. I feel much more confident now that we had Cardinal come in and take preventive measures to protect us.

We have been working with CDS for many years now. They are our go-to team for all our IT needs. We haven't been disappointed yet.

We were concerned that we had been compromised and our client data had been exposed through the Internet. We contacted Cardinal Data and their Cyber-Security team performed a thorough assessment and tested the network. They even gave us a check list of things to fix and helped us manage the project of fixing of our network.

The large search firms were unable to find the "purple squirrel", someone with just the right skills and business knowledge that we needed. CDS presented us with three qualified candidates and it was absolutely worth the wait. They did more than just check skills against a job description. CDS made certain our new employee would be able to succeed in the new role which made it possible for our project to succeed. This quality is rare to find nowadays in a full-service IT firm.
