Pablo Gutiérrez
Cybersecurity & IAM Engineer
Transitioning to Pentester

Blue Team → Red Team • OSCP Preparation • HTB Practice • Active Directory Security

Currently a Cybersecurity & IAM Engineer specializing in Blue Team operations, actively transitioning to offensive security. Preparing for OSCP certification while maintaining rigorous practice through Hack The Box and developing security automation tools. My extensive IAM background provides a unique perspective on defensive postures—understanding access controls, user management, and data protection—which strengthens my offensive security capabilities.

About Me

With a foundation in Telecommunications Engineering, I've always been drawn to understanding how systems communicate and interconnect. I specialize in Penetration Testing, though I'm currently working on a Blue Team where I focus on identity and access management and automating the security of the information we protect. This dual experience gives me valuable insight into both offensive and defensive security perspectives.

I've always wanted to be an ethical hacker—to protect systems before malicious actors do, giving organizations time to correct vulnerabilities and protect their information. My Master's thesis project involved designing, building, and comprehensively auditing a full Active Directory lab environment from scratch, which deepened my expertise in attack methodologies like Kerberoasting, AS-REP roasting, and various privilege escalation vectors.

Within penetration testing, I specialize in Active Directory, but I cover the full cycle from OSINT and network scanning to privilege escalation, lateral movement, and brute force attack techniques to achieve our goals.
