WHY COMPANIES TRUST US?

98% of Companies Fail. Will Yours?

Real-world cyber threats demand real-world testing.

Our Adversary Simulation replicates APT attacks, deploying custom malware, evasion techniques, and real cybercrime tactics within your infrastructure.

Test your security stack under real-world conditions.
Evaluate EDR, XDR, SIEM, and SOC response times.
Expose weaknesses before real attackers do.

We test. You improve. Using MITRE ATT&CK and our custom methodologies, we challenge your security teams, measure response times, and help you build cyber resilience.

98% of companies fail our adversary simulations. Do you trust your defenses?

How We Help You To Test Your infrastructure

We provide cutting-edge security testing to ensure your infrastructure withstands real-world threats!

Adversary Simulation & Red Teaming

We simulate advanced APT attacks to assess how well your infrastructure can resist real-world cyber threats. Our approach mirrors the techniques used by state-sponsored actors and cybercriminals.

Web Application Penetration Testing

Identify and exploit vulnerabilities before attackers do. Our comprehensive security testing covers OWASP Top 10, API security, and business logic flaws, ensuring your web applications remain secure.

Secure Code Auditing

We perform in-depth source code analysis to detect backdoors, misconfigurations, and security vulnerabilities that could lead to exploitation. Our focus is on secure software development practices.

Detailed Reporting & Remediation Support

Beyond just testing, we provide detailed reports with risk-based prioritization, actionable insights, and direct collaboration with your team to ensure remediation is effective and efficient.
