☠️About me
Gurpreet Singh ~ Senior Cybersecurity Analyst | Red Teamer | PQC & Cryptographic Resilience | Cybersecurity Professor
Cybersecurity Analyst with experience in network security, penetration testing, red team operations, and cryptographic resilience (Post-Quantum Cryptography - PQC). I focus on identifying and mitigating real-world vulnerabilities before they become threats, while strengthening organizations against emerging risks such as quantum computing attacks.
I specialize in:
Red Team assessments and adversary emulation
Internal and external penetration testing
Web application, mobile application, and Wi-Fi network testing
Hardening networks and systems
Translating technical findings into clear, actionable insights for businesses
Implementation of Post-Quantum Cryptography (PQC) strategies, including system analysis, critical asset mapping, CBOM development, and definition of strategic adoption plans to future-proof cryptographic infrastructures
I follow industry-recognized frameworks such as MITRE ATT&CK, NIST SP 800-115, Crypto-Agility Maturity Model (CAMM), and ISO/IEC 27001 to ensure my testing is structured, consistent, and aligned with best practices. I also use Python, Bash, PowerShell, and C# to automate tasks and improve response times.
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.
Fluent in Spanish and English, I communicate and collaborate effectively across diverse teams and excel at managing multiple complex tasks efficiently.
