☠️About me

Gurpreet Singh ~ Senior Cybersecurity Analyst | OSCE³ | Red Teamer | PQC & Cryptographic Resilience | Cybersecurity Professor

I specialize in red team operations, advanced penetration testing, and Post-Quantum Cryptography (PQC) strategy. I've led red team engagements across environments of 5,000+ endpoints, uncovering critical attack paths and improving detection coverage by 40%.

I specialize in:

Red team assessments & adversary emulation (MITRE ATT&CK)
Internal/external network, web app, mobile app & Wi-Fi pentesting
Cryptographic asset discovery, CBOM development & PQC migration planning
Hardening networks and systems
Translating technical findings into clear, actionable insights for businesses

On the PQC front, I help organizations future-proof their cryptographic infrastructure through system analysis, critical asset mapping, and phased adoption roadmaps aligned with NIST and the Crypto-Agility Maturity Model (CAMM).

Alongside my technical work, I’m a cybersecurity professor and trainer, helping professionals and students deepen their understanding of offensive security, vulnerability management, and real-world defense strategies.

I also use Python, Bash, PowerShell, and C# to automate tasks and improve response times.

Fluent in Spanish and English, I communicate and collaborate effectively across diverse teams and excel at managing multiple complex tasks efficiently.
