Testudo Defense Group brings operational security experience to the organizations that need it most — small and mid-sized businesses without a security team of their own.
Testudo Defense Group is a veteran-owned cybersecurity consultancy based in Charleston, South Carolina, working with clients across the United States. Our consultants bring more than a decade of hands-on experience defending real networks — not just advising on them.
That experience spans incident response, cyber threat intelligence, digital forensics, national and information security, and offensive security. It means when we tell you a risk matters, it’s because we’ve seen what happens when it isn’t addressed.
The Roman testudo — the tortoise-shell formation — was built from overlapping shields held by a disciplined unit. Layered, coordinated, and hard to break. That’s the goal for every business we work with.
The disciplines our consultants draw on across every engagement.
Experience running real incidents end to end — which is what makes our tabletop exercises and readiness advice realistic rather than theoretical.
Tracking the actors and techniques actually being used against specific industries, and translating that into priorities a business can act on.
Deep familiarity with how intrusions unfold and what they leave behind — the detail that separates useful findings from generic checklists.
Background working in environments with rigorous security requirements, applied at a scale that fits a smaller business.
Understanding how attackers think and operate, used strictly within authorized, agreed boundaries to test defenses safely.
Years in security operations centers monitoring, triaging, and responding — the day-to-day reality of defending a network.
A quick, no-pressure look at where your business stands and the fastest wins to shore it up.
