Who we are

ABOUT US

Karasu is an offensive and defensive cybersecurity firm led by hands-on practitioners. We approach every engagement from the perspective of a real adversary, combining red team operations, continuous monitoring and threat intelligence into a single, coordinated security posture.

Each engagement begins with structured reconnaissance and concludes with measurable hardening. We deliver clear, evidence-based findings and validated proof of exploitation, so that defensive investments are grounded in demonstrated risk rather than assumption.

Our team holds industry-recognized certifications and operates under strict rules of engagement, aligning every assessment with frameworks such as MITRE ATT&CK, OWASP and the NIST Cybersecurity Framework. The result is security work that is repeatable, auditable and defensible to both technical teams and leadership.

How we work

What does a typical engagement look like?+

Every engagement starts with scoping and reconnaissance, moves through controlled exploitation and continuous reporting, and ends with a debrief plus prioritized, measurable remediation guidance. You always know what we are testing and why.

How do you handle sensitive data and access?+

All work is performed under signed NDAs and rules of engagement. Access is scoped to the minimum required, credentials are handled through secure channels, and evidence is stored encrypted and destroyed on request after delivery.

Do you cover both offensive and defensive needs?+

Yes. We operate red team and penetration testing on the offensive side, and SOC monitoring, incident response and threat intelligence on the defensive side — coordinated so findings from one directly strengthen the other.

What do the final deliverables include?+

A technical report with reproducible proof of exploitation, an C-Level summary, a prioritized remediation plan, and a follow-up validation to confirm the issues were effectively closed.

01 — Offensive Security

Red team operations, penetration testing and security research conducted under controlled, contractual engagements. We assess exposure the way a real adversary would and deliver evidence-based findings with clear remediation paths.

02 — Defensive Operations

Continuous SOC monitoring, incident response and managed detection. Our teams detect, contain and remediate threats across your infrastructure, reducing dwell time and measurable business impact.

03 — Threat Intelligence

Actionable intelligence that maps who is targeting you, how and why. We anticipate emerging risks and feed those insights directly into both offensive testing and defensive operations.
