Zero Gaps! Magenta Strategies

"I'm a cyber professional with blue, red, and purple skills which makes my strategies magenta."

In the world of cybersecurity, Red Teams break, Blue Teams defend, and Purple Teams bridge the gap. At ZeroMagenta we blend them. Gracia explores the edges of digital defense, ethical hacking, and cyber strategy with a sharp mind, a fearless spirit, and a commitment to reshaping how we think about cyber resilience. 

“I’m Magenta a blend of all worlds. Offensive where I need to break through, defensive where I need to protect, and strategic where I need to connect the two. Zero Magenta is more than just my company name, its my statement!”

What I'm Working On

Focused on the defensive side of the threat landscape, one project at a time.

Security Automation

I'm building an AI-assisted triage tool that queries live Sentinel alerts and maps finding to MITRE ATT&CK and D3FEND, cutting through the noise so the focus stays on understanding the threat and the best path to countering it.


Email Security

Phishing remains one of the most effective initial access vectors in the threat landscape. I work with email authentication protocols like SPF, DKIM, DMARC to understand how attackers abuse mail infrastructure and how defenders can close those gaps.

CTFs

CTF competition is how I stress-test my skills in real time. Through year-round training and events like NCL, I work through log analysis, alert triage, and incident response scenarios that mirror real-world conditions, building the kind of muscle memory that translates anywhere threats need to be caught and stopped.

UTSA

UTSA - Bachelor of Business Administration, Cybersecurity

I began my cybersecurity journey at the University of Texas at San Antonio, one of the top ranked cybersecurity programs in the nation. The program gave me direction and exposed me to the fundamentals. But my real growth came from going further on my own, building labs, pursuing certifications, competing in CTFs, and creating tools from scratch. That combination of formal education and relentless self-study is what ZeroMagenta is built on.
