Who I teach, and where to start

Three kinds of reader arrive here with three different questions. Each has its own door.

• I know which course I need

  An engineer or administrator who has already picked the course. The catalogue lists every course I currently teach, with duration, outline and the certification it supports; each one has a request link that goes to Red Education.

• I need to train a team

  A manager with six, fifteen or forty engineers, mixed experience levels, a time zone and a date. A private class can be shaped around the group and run in your working hours; the two engagements Red Education published further down show what that looks like.

• I know the capability we need, not the course

  A new BIG-IP operations team, F5 administrators moving into WAF, a FortiGate team that keeps calling support, engineers moving to SASE. Start from the outcome; choosing the sequence is part of what I do.

How I teach

The official curriculum defines what the course must cover. My role is to connect it to the mechanisms underneath, the operational consequences, and the kinds of problems engineers meet when the system is actually running. Three principles do most of the work.

1. Mechanisms before memorisation

   A feature is explained by what it does to the packets, the sessions and the state, not by the position of a checkbox, because the engineer who understands the mechanism can reason about a situation the slide never showed.

2. Practice with purpose

   Hands-on labs are a core part of the technical courses I deliver, in the official lab environment provided for the curriculum. They are there to test understanding, not to imitate a recipe: the point is to see the system behave, break it, and explain what happened.

3. Adapt to the room

   The same curriculum needs very different emphasis depending on who is sitting there. Experienced groups move quickly into application and troubleshooting; newer groups spend the first hours on the foundations the labs rest on. Questions from your own environment are welcome, and often the best part of the day.

Since 1996 the work was implementation: designing networks and standing them up, troubleshooting them under pressure, and being the person called when a critical availability or security incident halted a business, for vendors and for some of the largest organisations in Brazil. That is where the examples come from.

Evidence from students

Five of the recorded reviews and recommendations, chosen for what each one shows: the explanations, the pace, the depth, and what the training was worth back at work. Every one is verbatim, with its source.

• On the explanations and the pace, F5

  I recently completed an F5 training session with Mr. Rodolfo Nutzmann, and I must say he is an exceptional instructor. He has a great way of breaking down complex technical concepts into digestible details. I particularly appreciated how he balanced the theoretical instructions with real-world examples and provided valuable reference links for deeper learning. His pace is perfect for ensuring everyone follows along. Highly recommended! Much appreciated, Rod, and keep up the excellent work!

• On technical depth and engagement, F5 LTM

  Rodolfo Nutzmann delivered the F5 LTM training with a strong level of technical depth and clarity. He demonstrated solid expertise in the subject and was able to explain complex concepts in a practical and easy-to-understand manner. He was very helpful throughout the course, actively engaging with participants, addressing questions promptly, and ensuring everyone was able to follow along.

• On a Fortinet class

  Clear explanation of doubts and complete review about the Fortigate Firewall was well provided by instructor Rodolfo nutzman

• On what it was worth back at work, four courses on BIG-IP

  I did 4 training courses with this guy. His knowledge and skill were extremely important in the face of the questions and answers I needed; he was extremely helpful and genuinely interested in the difficulties I faced. I recommend this guy's helpfulness without a doubt, and thanks to his explanations I was able to work around some situations I had run into while providing services on the BIGip product. Thank you, Rodolfo, for the support, and I remain available for whatever I can help with.

• On an Extreme Networks course, and the implementation that followed

  Rodolfo was an excellent instructor for the Extreme Networks equipment course. He demonstrated complete command of the technology and the teaching skill needed to pass that knowledge on to our team.

  Beyond that, he worked on the implementation of our metropolitan network. Once again he demonstrated complete command of the technology and creativity in solving problems.

Where the classes are, and when

Delivered across the Americas, Europe, the Middle East, Africa and Asia-Pacific, in classes scheduled around Australian, Singaporean, Indian, European and American working days. The clocks below are live, in the regions I teach in; set a class start time and see what it means everywhere else.

What happens after the class

The course ends. The reference material does not.

• The next course

  Each course page names what it prepares for and what naturally follows it, so a team can plan a sequence rather than a single week.

• The certification

  Official courses support the knowledge and skills behind the vendor certifications, and the free study guides here cover what each exam actually tests. The goal of the class is operational understanding, not memorising likely questions, and no course confers a certification by itself.

• The reference shelf

  Hundreds of articles, the tools and the glossary stay available after the last lab, written by the same instructor on the same platforms, so what was explained in the room can be looked up again months later.
