Cybersecurity startup Gillware Digital Forensics rebrands as Tetra Defense; raises $3M Series A to accelerate growth

Gillware Digital Forensics, a Madison, Wisconsin-based cyber incident response and proactive cybersecurity consulting startup, today announced its rebranding as Tetra Defense. The startup also said it closed $3 million series A investment round to aggressively expand its team, sales and marketing efforts, as well as broaden and enhance product and service development.

The round was led by Mendota Venture Capital LLC, with participation from several investors. The investment is the first funding round by Tetra Defense since launching in 2016. In conjunction with the funding, Tetra Defense also announced that Nick Jackson, Principal at Mendota Venture Capital LLC, and Mike Victorson, President and CEO of M3 Insurance, will join its Board of Directors.

“As cyberattacks and other incidents impact more organizations than ever before, Tetra Defense’s funding round and rebrand are well-timed to match the rapidly growing demand for cyber incident response and proactive information security services,” said Nick Jackson, Principal with Mendota Venture Capital LLC. “Tetra Defense is an exceptional provider of these services. We are thrilled to collaborate with and support them as they expand and continue to build an impressive organization in a growing industry.”

Tetra Defense, formerly Gillware Digital Forensics, helps organizations respond to and recover from cyber incidents like ransomware attacks, business email compromise and data breaches. Many victim businesses are brought to a grinding halt and cannot fully operate. Tetra Defense is one of the only incident response firms to assist with and prioritize restoration of operations to limit downtime. Additionally, Tetra Defense helps organizations develop effective information security programs and defenses to lessen the risk of a cyber incident with services including IT risk assessments, penetration testing, email phishing training, incident response plan testing and more.

“Businesses of all sizes are increasingly finding themselves at war with cyber criminals around the globe,” said Scott Holewinski, CEO. “This investment gives us the resources we need to build new and innovative tools and services to help our clients respond and defend against future cyber threats.”
