Badhan Ahmed Topu

Cybersecurity Engineer | SOC Analyst | Trainer

I’m passionate about securing digital infrastructure and doing it with integrity, and I've been working for a Bank for the last 6 years with deep hands-on experience in IBM QRadar SIEM, SOAR, PAM, FIM, XDR and compliance frameworks like ISO 27001 and PCI-DSS. I’m here to learn, to lead, and to leave systems better than I found them. I love digging into vulnerabilities, threat hunting, crafting use cases, and pushing the limits of what a security operations center can do.

About Me

I enjoy guiding others — whether it’s junior analysts, colleagues, or just curious folks trying to break into infosec.

I’m not into fluff or unnecessary hype. I respect people who do the work, stay curious, and treat others with decency. If that’s you, I’ll always make time to help.
