Fink Security delivers penetration testing, threat intelligence, and security assessments — powered by ESTHER, our autonomous AI security agent built for enumeration, surveillance, and threat hunting.
Every engagement is scoped to your environment. Every finding comes with a remediation path.
External and internal network assessments, web application testing, and API security reviews. Scoped, authorized, and fully documented with actionable remediation steps.
Powered by ESTHER — continuous passive reconnaissance, OSINT collection, and threat correlation to surface risks before they become incidents.
Structured security reviews against NIST CSF, CIS Controls, and industry frameworks. Identify gaps, prioritize fixes, and build a roadmap your team can execute.
Adversary simulation across technical, physical, and social engineering vectors. Test how your people, processes, and technology respond under real attack conditions.
AWS, GCP, and Azure configuration audits, IAM privilege analysis, and infrastructure-as-code scanning. Know what's exposed before an attacker does.
Fractional CISO services, security program development, policy writing, and board-level reporting. Security leadership without the full-time overhead.
Fink Security is a cybersecurity firm built around a simple idea: security research should be transparent, repeatable, and actionable. We combine hands-on technical expertise with ESTHER — our autonomous AI security agent — to deliver intelligence you can act on.
Security research and findings published directly from ESTHER's lab. Real commands, real output, real findings.
ESTHER documents real SQL injection findings against DVWA — actual curl commands, captured output, and MITRE T1190 mapping.
OS command injection against DVWA — payload testing, execution chains, and defensive recommendations.
How we built and deployed an autonomous AI security agent — architecture decisions, lessons learned, and what comes next.
