Top Services
Penetration Tests
Every realistic attack scenario that may target your organization is simulated through our comprehensive, methodology-driven tests, so weaknesses surface in a controlled environment instead of during a real breach.
Vulnerabilities discovered across your systems are documented in clear reports, each paired with prioritized, practical recommendations that guide you toward the optimal solution.
IT Security
Your data is protected with DEF24 through technology-theft detection together with disk, network, and efficiency analysis. We keep critical information inside your organization and out of the reach of unauthorized hands.
Reverse Engineering
DEF24 provides detailed reports by analyzing open-source and compiled materials with both active and passive methods, uncovering how a piece of software behaves, where it originated, and what risks it may be hiding.
Consultancy
Providing consultancy on network systems, software cyber security architecture, cloud security, physical environments, and company security policies. Our experts build protection into every layer of your infrastructure from the very first project phase, so security is designed in from the start rather than bolted on later.
Preventing, predicting, and suggesting solutions for possible interruptions caused by domain names in the later stages of your projects. From WIPO disputes to domain intelligence, valuation, and security, we safeguard the digital identity your brand depends on.
