Nicola Casto
Since 2000 I have been helping companies and public administrations digitise, innovate and secure people, processes and machines. From Sicily, across all of Italy.
It all began at eleven years old, in front of a computer.
It was love at first sight. That machine hinted at a power and possibilities that captured me instantly. From that day on, study and experimentation became my hallmark, until technology became the centre of my professional life.
I was born and raised in Noto, Sicily... far from the centres of innovation. It was never a limit. It was my training ground. In 2000 I founded Casto Sistemi, in 2015 Maicron S.r.l., and in 2024 I earned my degree in Computer Engineering. Not for the title... for the knowledge.
When I see a problem, my mind looks for the solution. Sometimes the solution doesn't exist yet, so I build it. That's how Immunibox was born, and how three patents followed.

I don't sell technology. I solve problems.
Every project starts with a real analysis of your company, your goals and your budget... and ends with a measurable result.

Cybersecurity
Cybersecurity is not a product, it's a process. I design and manage your company's defences at every level.
- Vulnerability assessments and security testing
- Protection of networks, servers and endpoints
- Backup, disaster recovery and continuity
- Incident monitoring and response
Digital forensics
Expert reports and digital forensic analysis for lawyers, companies and individuals. Technical rigour, in a language even a judge can understand.
- Expert reports for litigation
- Forensic analysis and evidence preservation
- Internal investigations and technology disputes
Training
I train employees, technicians and executives. I wrote a book to explain IT to everyone... rest assured I can explain it to your office too.
- Cybersecurity awareness
- Specialised technical courses
- Tailor-made training for your company
First sold in thousands of copies. Then given to the world.
I wrote Talenti Sconosciuti to open the doors of IT to everyone... a journey inside the digital world, revealing its mechanisms and making them understandable even to non-experts.
It reached #1 on Amazon in the cybersecurity category. Then I did the thing that suits me best... I made it free for everyone, forever.
Proof, not promises. The screenshot of the Amazon chart... #1 in the Computer Security category.
Where you'll find me, beyond the desk.
Conferences, international fairs, institutional panels, training. Innovation happens by meeting people.









When the newspapers speak... and so do the institutions.
From the Sicilian press to the country's most important chamber: entry into the UnionCamere register, the Immunibox story, and Maicron S.r.l. accredited at the Chamber of Deputies as a stakeholder on cybersecurity, NIS2 and artificial intelligence.
Let's talk.
