Information security & cybersecurity consulting
Risk assessments that find your actual exposure, then a security architecture, policies, and best practices built around your business — not a template pulled off a shelf.
Cybersecurity that thinks like the people trying to breach you.
JBTSEC helps businesses and people close the gaps attackers actually use — from risk assessment to incident response, from a company network to the phone in your pocket. Built and run by a practitioner who has secured bank infrastructure and cloud environments, not a call center.
Our mission
Keep the bad guys out
Most breaches don't start with anything sophisticated. They start with a router still running its factory password, a laptop three updates behind, a phone with no second factor on the account that holds everything.
We close those gaps at scale for businesses. The same gaps sit in almost every home — most people were simply never shown what to check. Hardening a company network and hardening a family's devices is the same craft, and we do both.
What we do
Seven ways to close the gap
Cloud computing solutions
Secure, well-configured migration to AWS and other cloud platforms, with access controls and infrastructure hardening built in from day one — not patched on after a breach.
DevSecOps engineering
Security folded into your development and operations lifecycle: automated checks, continuous integration, and continuous delivery that ship fast without shipping vulnerabilities.
Cybersecurity assessments & penetration testing
Ethical hacking against your networks, web applications, and mobile apps, with specific, practical findings — not a 40-page report that gets filed and forgotten.
Incident response management
Continuous monitoring, investigation, and a tested action plan for when something goes wrong — built to minimize downtime and damage, not to assign blame after the fact.
Security awareness training
Practical sessions on spotting phishing, handling data safely, and building everyday security habits. Run for company teams, schools, and community groups alike — because the people targeted most are often the ones with no IT department behind them.
Private client security
A confidential review of the devices and accounts your life actually runs on — phones, laptops, home routers, cloud storage — followed by the hardening work itself. The same discipline applied to bank infrastructure, scoped to one person or one household.

About JBTSEC
Led by someone who has done the work
Fifteen years of securing things that couldn't afford to go down — bank platforms, cloud environments, deployment pipelines — taught the same lesson over and over: attackers rarely need anything clever. They need one gap nobody checked.
JBTSEC is a São Paulo–based consultancy built around closing those gaps, whether they sit in a company's network or in a family's devices. Clear risk assessments, hands-on implementation, and incident response led by a practitioner, not resold through a call center.
