Problem
Organizations often rely on automated security scanning tools that produce high volumes of false positives and miss complex, business-logic vulnerabilities that real attackers exploit. Security teams struggle to prioritize remediation efforts without clear evidence of exploitability or actionable guidance, leaving critical attack paths unaddressed.
Solution
zsigma.ai delivers offensive-first security assessments grounded in manual penetration testing to uncover real, exploitable attack paths and provide actionable remediation. Their engagements combine hands-on testing with complementary tooling, producing executive-level and technical reports that detail vulnerabilities, fix guidance, and supporting evidence. The company offers a spectrum of services, including web and API penetration testing aligned with OWASP, cloud security reviews for AWS/Azure/GCP, external attack surface mapping via OSINT-driven reconnaissance, and internal network and Active Directory security testing. Each engagement includes a prioritized remediation plan and a retest option to verify fixes, ensuring clients can measure improvement and maintain a hardened security posture.
Target Audience
Primary customers are security teams, engineering leads, and CISOs at technology companies and enterprises that require manual, evidence-rich security assessments for web applications, cloud infrastructure, and internal networks.
