Cybersecurity.
Beyond email.
Across the
attack surface.
I’m Karthik — a security analyst and engineer exploring how to detect, understand and defend against threats across applications, networks, cloud and emerging AI systems.

LIVE GLOBAL ACTIVITY
The threat landscape, in motion.
A live global view of threat activity, presented separately from the portfolio so it never obscures the work.
OPEN CHECK POINT THREAT MAP ↗01 / A SHORT INTRODUCTIONHYDERABAD · INDIA
One field.
Many frontiers.
Good cybersecurity doesn’t stop at the inbox. It follows the threat wherever it goes.
My work spans enterprise incident response, application and network defense, cloud and Linux infrastructure, vulnerability assessment, cryptography, IoT, and AI-powered investigation. Across every layer, the aim stays the same: understand the evidence and help people act with confidence.
