CISSP · GPEN · GCIH  /  Adversary Emulation, Detection & Response

Defense that thinks like the adversary.

I lead security operations centers and offensive security teams. One side detects earlier and responds with discipline. The other tests those defenses the way real attackers would. Both report in language the board understands, backed by hands-on depth in SIEM, SOAR, identity and penetration testing.

01  Leadership

An operator who speaks executive.

Rudy Villalona seated at a table, smiling

Exceptional security programs are built by people, not technology. Technology amplifies the culture, leadership and talent behind it. People first, technology second.

My work sits where the analyst floor meets the boardroom. I build and run 24/7 security operations, set the service levels the business and its executives hold us to, and develop the analysts and engineers who meet them. I stay close enough to the tooling to challenge a detection rule or a pentest finding, and far enough above it to tie the work to business risk.

I lead from the offensive side as well. Penetration testing, red team and adversary emulation work shows whether defenses hold up against the techniques real attackers use, and the findings go straight back into detection and response.

When I joined FIT Cybersecurity as SOC Manager, analyst burnout, low morale and turnover were persistent problems. Within six months I helped reduce turnover to under 5% by restructuring the SOC, balancing workloads and making operations more predictable. The goal was a culture where people could thrive and do their best work.

I never ask my team to do something I wouldn't do myself. That has meant long nights of ransomware containment, payload unpacking and building multi-zoned Suricata pipelines alongside them. I've also interviewed hundreds of cybersecurity professionals and invest heavily in coaching and mentorship.

02  Operating model

How an incident moves through a well-run SOC.

The lifecycle I build teams, tooling and metrics around. Each stage has an owner, a measure and a handoff.

STAGE 1

Detect

Tuned SIEM correlation and EDR telemetry surface the signal worth a human's time.

MTTD
STAGE 2

Triage

Tiered analysts validate, enrich and assign severity against a shared rubric.

MTTA · P1–P4
STAGE 3

Respond

SOAR playbooks and incident commanders contain the threat with documented decisions.

MTTC
STAGE 4

Recover

Systems return to service, stakeholders are briefed, and leadership gets a clear account.

MTTR
STAGE 5

Improve

Lessons learned and adversary emulation results feed detections, runbooks, training and the next quarter's priorities.

06  Recommendations

In the words of those I've worked with.

Four analysts and engineers who reported to me directly, on what it was like to work on my team.

Rudy is the kind of leader who makes a team stronger just by being part of it.

Rudy interviewed and hired me for my first role in cybersecurity, and I’ll always be grateful he took a chance on me. As my SOC manager, he set the tone for the whole team.

What stood out most was how much he cared about the people in the SOC. He worked hard to keep the team together and made sure our concerns were heard and acted on, which mattered a lot on overnight shifts where it’s easy to feel disconnected. He was also excellent at handling difficult client situations, staying calm and professional while protecting both the client relationship and his analysts.

Tyler ReynoldsSOC Analyst, FIT Solutions, LLCDirect report · Nov 2026

Rudy joined the company when we needed him the most.

Our team had lost 2 managers and a PenTester in a 6 month period. Rudy came in and took over management duties, as well as participated in several PenTests. Our team grew from only 4 analysts to 9 in less than a year. As the SOC manager, Rudy implemented bi-weekly training in a Ted Talk style forum for the team.

Adam LesterDirect report · July 2023

He is a manager who puts people first.

Rudy was an exceptional manager during my time working with him as a Cybersecurity Analyst/Engineer at FIT Cybersecurity. During our bi-weekly 1:1 meetings, he was a great listener and did his absolute best to align each security team members goals with that of the mission of the company. He trusted the skills and abilities of his team and allowed us to perform the work we were hired to do.

Rodney FloresTechnical Security Engineer, Yahoo Paranoids · GIME, GCIA, GCIH, GSECDirect report · Dec 2022

Rudy has a remarkable ability to lead with both intelligence and empathy, creating an environment where I felt encouraged to tackle challenges I didn’t initially think I could handle.

Working under Rudy for nearly three years has been one of the most transformative experiences of my career. He’s not only an exceptional leader but also a mentor who truly cares about the growth and success of his team. His guidance has had a huge impact on my professional development, and I genuinely credit much of my success to his leadership and support.

On building security teams.

What I’ve learned from interviewing hundreds of cybersecurity professionals.

Recent on LinkedIn  /  Offensive Journal

API documentation: a simple way to save time, money, and improve security assessments

One thing I’ve noticed with increasing frequency during API security engagements is the lack of clear, comprehensive API documentation. Having access to an OpenAPI/Swagger specification before beginning an assessment can make a significant difference in both efficiency and cost.

The objective isn’t simply to test every endpoint equally. It’s to understand which endpoints introduce the greatest business risk and prioritize accordingly.

Of course, documentation isn’t a substitute for discovery. I cannot tell you how many times I come across undocumented and forgotten endpoints.

  1. Know thyselfIdentify endpoints, HTTP methods, authentication requirements and potential exposure points.
  2. Prioritize by functionalityAn endpoint processing financial transactions deserves different attention than one returning public data.
  3. Improve threat modelingUnderstand business logic, trust boundaries and the impact of compromised functionality.
  4. Save time and moneyLess time figuring out what an API does means more time testing what matters.
  5. Deliver more valueBetter scoping leads to focused testing, meaningful findings and actionable remediation.
