0x3 Security

0x3 Security | Built by Hackers Not Suits. Trusted by Businesses At 0x3 Security, we don’t just check boxes—we think like adversaries. Founded by ethical hackers and red-team operators, our mission is to help small and mid-sized businesses defend, detect, and respond to modern cyber threats with enterprise-grade protection at SMB-friendly scale. We bring the mindset of attackers and the precision of defenders to every engagement, combining offensive tradecraft with proactive defense. From penetration testing to managed EDR, we help you see what threat actors see—then shut it down before it becomes a breach. What We Do • Penetration Testing & Red-Team Ops – Identify real vulnerabilities through hands-on testing that simulates actual threat actors. • Managed EDR & Endpoint Security – Powered by CrowdStrike and NinjaOne, we detect and stop ransomware, malware, and insider threats in real time. • Threat Hunting & Incident Response – Continuous detection and investigation to eliminate hidden threats and speed recovery. • Security Awareness & Training – Equip your employees to recognize phishing, vishing, and social engineering attacks. • Compliance & Risk Management – Build resilience across HIPAA, SOC 2, PCI-DSS, and NIST frameworks without unnecessary complexity.

We translate complex technical risks into clear business outcomes that reduce downtime, protect revenue, and safeguard reputation. We partner with clients long-term to strengthen defenses, improve visibility, and create a measurable security culture. Whether you’re recovering from an incident or building a security program from the ground up, we deliver clarity, confidence, and control.
