Cybersecurity Firm
Cybersecurity Expertise Built for Modern Threats
Coalfire DivisionHex helps organizations uncover real-world exposure, validate their defenses, and respond to modern threats. Our threat-informed teams bring together offensive security, defensive security, managed security, and AI/ML expertise to help security leaders make better decisions faster.
One Cybersecurity Partner Across the Attack Surface
The right cybersecurity firm should do more than identify vulnerabilities. DivisionHex combines deep technical expertise, adversary-informed testing, threat hunting, managed security, and AI/ML risk services to help organizations understand what is exposed, what attackers could exploit, and what to do next.
Whether you need to test a critical application, investigate suspicious activity, strengthen detection and response, or understand emerging AI risk, our specialists help turn security uncertainty into a prioritized action plan.
Fear no Future with Coalfire DivisionHex™
DivisionHex marks the evolution of Coalfire – going beyond compliance to tackle the threats compliance alone can’t stop. We hand-picked a team of offensive, defensive and managed cybersecurity experts to close the gap between compliance and achieving full security on all sides.
Offensive Security
Break your system before an attacker does.
We simulate real attackers using real tactics — tearing through your defenses to reveal what they don’t want you to see. Every exploit teaches. Every breach, controlled.
Defensive Security
Defense isn’t passive. It’s precision.
We hunt the hidden, decode the noise, and guide your team to react with intelligence and strategy. Every move measured. Every threat contained.
Managed Security
Defense that doesn’t sleep.
We deliver continuous visibility, exposure management, attack surface monitoring, and threat intelligence; keeping your environment sharp, steady, and ahead of security risks.
AI + ML Security
Every AI/ML breakthrough creates a new blind spot. DivisionHex dissects data flows, architectures, and defenses through modern, real world AI / ML application threat modeling and testing — to identify vulnerabilities before they turn into headlines.
