Security operations
Continuous monitoring of your environment with analysts in São Paulo. We watch the signals that matter and escalate only when there is something real to act on.
Cyber defense studio · São Paulo
The systems you cannot afford to lose deserve a real defense.
Sentivel protects critical infrastructure, financial platforms, and the data that runs them — with monitoring, response, and architecture designed for actual adversaries, not checklists.

Our position
Most breaches are not the work of brilliant attackers. They are the result of quiet drift — an unpatched gateway, a credential that outlived its owner, an alert nobody read at 03:00. The work of defense is less about heroics and more about attention that does not lapse.
We built Sentivel around that idea. A security program is not a product you install once; it is a discipline that has to hold up on a bad Friday, during a migration, on the day a key engineer leaves. So we treat your environment as something to be understood deeply before it is ever locked down. We read your architecture the way an operator does, not the way a brochure does.
That means fewer assumptions and more evidence. Before we recommend a control, we want to know how a real intrusion would move through your systems — which account it would reach first, which segment would let it spread, how long it could stay before anyone noticed. The answers tend to be uncomfortable. They are also the only honest place to start.
What we deliver is not a dashboard full of green checkmarks. It is a defense that behaves correctly under pressure: detection that fires on the right signals, a response plan your team has actually rehearsed, and an architecture that fails safely when something goes wrong — because eventually, something will.
Security is not the absence of incidents. It is the speed and clarity with which an organization understands what just happened.— Sentivel operating principle, written into every engagement
What we do
Four practices, one continuous defense.
We do not sell isolated tools. Each practice feeds the others, so detection informs architecture and every incident sharpens the next response.
Incident response
When something goes wrong, we contain it, trace it, and restore operations — then write down exactly what happened so it does not happen the same way twice.
Offensive testing
Controlled adversary simulation against your applications and networks. We find the path an attacker would take before they do, and document how to close it.
Security architecture
Identity, segmentation, and resilience designed into your platform from the start — so that a single mistake stays small instead of becoming a headline.

Common questions
What organizations ask before they begin.
How is Sentivel different from buying a security tool?
A tool gives you data. We give you a defense. Software can surface thousands of alerts, but it cannot decide which one matters at 03:00, contain an active intrusion, or redesign the part of your architecture that keeps failing. That judgment is the work, and it is what we provide alongside the tooling.
How does the cost compare to building an in-house team?
A capable internal security operations team in São Paulo means several specialists, around-the-clock shifts, and the tooling to support them — a structural commitment most organizations carry only once they reach significant scale. Engaging Sentivel gives you that coverage as a fixed monthly arrangement, and many clients keep us alongside a smaller internal team rather than instead of one.
Are you registered to operate in Brazil and aligned with the LGPD?
Yes. Sentivel is a registered company in São Paulo (CNPJ 41.829.305/0001-72) and our practices are built around the Brazilian General Data Protection Law (LGPD, Lei 13.709/2018) as well as the European GDPR for clients with operations abroad. Data handling terms are set out in every engagement before work begins.
What happens in the first weeks of an engagement?
We start by understanding your environment — its architecture, its critical systems, and how an intrusion would realistically move through it. From that map we agree on priorities, stand up monitoring, and define a response plan your team rehearses with us. Visible work usually begins within the first two weeks.
Do you work with our existing engineers and tools?
Almost always. We are not interested in replacing systems that already work. We integrate with the platforms you run, fill the gaps your team does not have time for, and hand over clear documentation so your engineers stay in control of their own environment.
Can you support a response if we are already dealing with an incident?
Yes. We take on active incidents as well as long-term engagements. If you are in the middle of something now, contact us directly and describe the situation — we will tell you honestly whether we are the right team to help and how quickly we can begin.
