JS
IT Manager
Soveriegn Nation

“Shane’s advice and council was fantastic during the breach. Without his expert advice and assistance we would have been dead in the water. That was a nasty malware infection!”

HC
IT Staff
SLED

“We couldn’t get rid of the malware using Traps or our regional VAR. 4D5A Security was a life saver. They spun up IR services immediately and knew exactly what to do to help us remove the threat from our facilities.”

SS
CISO
Manufacturing Client

“4D5A saved us millions in our breach. We were lucky to find such qualified staff to jump on our case so quickly and affordably.”

TS
Security Leader
Enterprise breach response

“We hired 4D5A Security to get risk of a ransomware threat. They found three different actors inside of our network! One was targeting our payroll and ,we didn’t even know about that one. We blocked all the attacks and performed post-breach actions with them to reduce risk proactively.”

HO
Head of Security
SLED sector

“4D5A’s affordable IR retainer save us thousands!”

SH
IT/Security Manager
Healthcare Sector

“When 4D5A Security started pen testing our network down, hard. We didn’t know what was going on. They helped us identify the problem and added it to their list of exclusions. This was a huge help for us, when we had never tested this area of our network before.”
