Angelo Barbosa · ethical hacker for more than 25 years
The distance
between you and a hacker
The vector
is a single
click.
A link in an email, an attachment, a login page that looks real. The attacker does not need to be close: you only have to take the last step for them.
Lateral movement
And it does not stop
at your computer.
From one compromised workstation, an intruder tries to reach everything else: servers, shared folders, backups, mailboxes. Every connection is a way in.
My work
I don't sell fear.
I sell solutions.
For more than 25 years I have been protecting companies and professionals in the digital world: I close off the routes before anyone can use them.

About me
About me
99% of companies believe they are safe from cyberattacks. Yet I find vulnerabilities everywhere.
I don't promise impenetrable systems:
anyone who does is lying!
But I can make you a hard target.
I help business owners and professionals through the digital transformation of their companies, with data security at the centre. I begin with a thorough analysis of the infrastructure they already have and work towards tailored solutions built to last.
I don't look for flaws to break things, but to protect them. I don't sell fear: I sell solutions.

What I build
From 1999 to today
I have been protecting companies since 1999.
I have been building my own solutions
since 2006.
In 2006, with Mobile Office, company email and files moved onto the phone and out of the office, at a time when working on the move was not yet within everyone's reach. From there, one piece at a time, today's products were born: every need that keeps coming up, company after company, becomes a product with a single job.
That is what I do: sovereign Swiss technology for companies that want to take back control of their data.

The infrastructure is in Switzerland.
No US provider, so neither the CLOUD Act nor FISA Section 702 applies.
Data protection by default, not as an option.
No data flowing back to the vendor.
From consulting to ongoing support: I secure and look after companies' IT, directly.

Digital sovereignty
‘A company without control over its data is just a target with a VAT number.’
If your data sits with a US provider, US authorities can demand it under the CLOUD Act, wherever the servers are. With a Swiss provider that has no US parent company, and servers in Switzerland, Swiss law applies. Not ideology: jurisdiction.

Sicurezza informatica per professionisti.
My book, in Italian: how to protect yourself from digital threats in the age of artificial intelligence. It introduces the 3V Method (Verify, Validate, controlled Velocity), which turns the human factor from the weakest link into the first line of defence.
Creator of KEYBOKY
No malware can infect ink on paper.
Back to the fundamentals of security: physical separation. Not an app, not a cloud password manager: a paper-based method that keeps passwords offline.

The four defences
$ ./defend --all
Close off the routes
before an attacker can use them.
$ ./fortify --data
[ ok ] position consolidated
Fortify the position
Solid defence
I have seen too many companies with data scattered everywhere, exposed. The first move is always to consolidate and fortify.
$ ./watch --adversary
[ ok ] active intelligence
Anticipate the adversary
Active intelligence
Defending is not enough. You need to know what the adversary is preparing, and see their moves before they make them.
$ ./scan --lateral

Cover the flanks
Peripheral vision
Threats do not only come head-on. You need systems that cover the blind spots and spot lateral movement.

Integrated ecosystem
Real strength lies in versatility: an ecosystem that covers every front, with pieces that talk to each other.

Who is Angelo Barbosa?
I am an ethical hacker with more than 25 years of experience in IT and information security. I protect companies and professionals from digital threats through tailored consultancy, security audits and training. I created KEYBOKY, an offline password management system, and wrote the book ‘Sicurezza informatica per professionisti’ (in Italian). My mission is to make the digital world safer for everyone.
What does being an ethical hacker mean?
It means using advanced security skills to find and fix vulnerabilities before criminals can exploit them. I always work with explicit authorisation, within strict ethical and legal rules. My goal is to strengthen digital defences, not to break them.
Why did you choose this path?
Because I believe security is a right, not a privilege. After seeing too many systems fail and too many companies suffer serious damage for lack of proper protection, I decided to dedicate my work to preventing that. My passion for computing, together with the wish to protect people and businesses, is what drew me to security in the first place.
What services does Angelo Barbosa offer?
I offer information security consultancy through POWERB, my firm, and free do-it-yourself tools, which you will find on the ‘Free resources’ page. I created KEYBOKY, a paper-based method for managing passwords. With my book I want to build real awareness, not the kind of fear that pushes people to buy devices that end up badly configured, creating a false sense of security.
What is KEYBOKY and how does it work?
KEYBOKY is a fully offline password management system that I created after 25 years in the field. It uses a paper-based method that combines mathematical randomness with physical separation: the credentials are not on any device, so malware or a remote attack has nothing to steal. It is not an app or a cloud service: it is an analogue system for people who want strong security without depending on digital technology.
How can I start protecting my company?
The first step is understanding your weak points. You can start with my free resources for a self-assessment. Remember: security is not a product you buy, but a process you build with awareness and the right tools.
Where do I start with your products?
Start with the free tools on the ‘Free resources’ page: in a few minutes you can see where you are exposed. Then pick the most urgent problem: if it is passwords, start with KEYBOKY; if it is knowing whether you are being targeted, start with CYBETOWER. Each product works on its own: you add the others when you need them.
Why does Switzerland matter for data security?
Because what matters is who holds your data, not only where it is stored. The US CLOUD Act allows US authorities to compel a US provider to hand over data, even when the servers are in Europe or in Switzerland. With a Swiss provider that has no US parent company and no US presence, the data stays under Swiss law, which protects it through the Federal Act on Data Protection (FADP). Knowing which law applies to your data is the first step to controlling it.
Are these products only for large companies?
No. They are designed for SMEs and professionals who cannot afford an IT department, but cannot afford to be vulnerable either. The complexity stays behind a simple interface: if you can use email and a browser, you can use my products.
