As investigations continue following the attack in Brussels last week, some are wondering if the terrorists could have been identified and stopped using better government tracking technology.

"We all create a pattern of life," Mark Testoni, SAP National Security Services President and CEO told CNBC. "It used to be pretty analogue, but now almost everything we do, whether on the internet, or walking through a city and being captured on camera, or applying for a job, is being captured in some sort of digital form."

Testoni said the challenge is bringing all the data together to help identify potential threats.

SAP National Security Services, an independent subsidiary of the software company SAP, provides software solutions and consulting to their clients. "It's a high speed database that connects people and places and things, in a way that we might not be able to do in our head."

While Testoni cannot specifically disclose their clients, they primarily are agencies within the U.S. government, but confirmed his work expands beyond the United States.
