What our clients say



The Lancaster Area Sewer Authority contracted with Blackthorn Information Security to examine a third party application that handled payments from our customers. Their highly detailed, comprehensive report revealed several important issues with this third party application, including a lack of security of our customers’ data.

Former System Administrator, Lancaster Area Sewer Authority, Lancaster, PA

When the Shelburne Fire Department server was infected with a deeply-rooted virus, we turned to Blackthorn Information Security. They were thorough in their investigation, eradicating the virus and explaining where it had come from.
