Our products are responsible for alerting our varied array of customers of potential Cyber and EW attacks by creative adversaries highly skilled at attacking.

Our CEMA team is comprised of both red and blue: hackers, programmers, mathematicians, quantum scientists, data scientists, even a physicist, so knowledge is easily gleaned in our team for those willing to ask. Problem solving, troubleshooting, and a desire to break things for good reasons will be our focus for consideration.
