About Tetra Defense

Originally founded in 2016 as Gillware Digital Forensics, Tetra Defense supports a global network of partners and clients from its offices in Madison and Milwaukee, WI. Since our founding we have grown into one of the most highly respected digital forensics, incident response and cyber risk management firms around. 


There has never been a challenge we haven’t accepted. With a team of former law enforcement, FBI agents, CISOs, IT leaders and the like, we’ve been up close and personal with investigations and incidents of every shape and size.


Early on we knew we were doing things differently than the rest. When our competitors considered a job finished, we saw so much more we could do to help the client. Whether it’s getting a business back up and running after a ransomware attack or mapping out a project plan to help businesses improve their cybersecurity defenses, we always go the extra mile.
