Threat monitoring
Continuous watch over endpoints, identities and cloud workloads. Alerts are triaged by analysts, not just forwarded — so your team hears about what actually matters.
Cyber defense · São Paulo
Security that follows how your business runs.
We watch the systems your operation depends on, contain incidents before they spread, and help your teams recover with the evidence to back every decision.
Why this matters
Most breaches are not loud. They are quiet, patient, and already inside by the time anyone notices.
How we think about defense →What we look after
Four areas cover most of what keeps a security team awake. We take them on as a continuous program, not a one-time audit.
Incident response
A defined playbook for the bad day. We isolate affected systems, preserve evidence, and coordinate the timeline so legal and leadership work from the same facts.
Posture review
A structured look at where exposure sits today — misconfigured access, unpatched services, third-party connections — ranked by what an attacker would reach first.
Compliance support
Documentation, controls and reporting aligned with LGPD and ISO 27001. We translate requirements into work your engineers can actually ship.
Identity & access
Who can reach what, and why. We tighten privileges, enforce multi-factor sign-in, and remove the standing access that turns one stolen password into a full compromise.
Team readiness
Tabletop exercises and simulated social-engineering campaigns that prepare the people, not just the tooling. Most intrusions start with a click — so we practice for it.

How we work
A program, in four stages
01 / Map
Understand the terrain
Before any tooling, we map what you run, what it connects to, and what would hurt most to lose. The work is shaped by your actual operation — not a generic checklist.
02 / Watch
Bring systems under view
We instrument endpoints, identities and cloud accounts, then tune the signal so alerts mean something. Quiet dashboards are the goal — noise is the enemy of response.
03 / Respond
Act on the day it counts
When something fires, a named analyst owns it end to end: contain, preserve, communicate. You get a clear timeline, not a flood of tickets.
04 / Strengthen
Close the gap that let it in
Every incident becomes a fix. We review what happened, adjust controls, and document the change so the same door does not open twice.

Good security is rarely visible. It is the incident that never reached your customers, the access that was already revoked, the quiet Tuesday that stayed quiet.
Recent work
A few engagements that show how the program adapts to different operations. Client details are anonymized at their request.
Logistics · 2025
From blind spots to a single view
A national freight operator had visibility across three disconnected tools. We consolidated alerts into one workflow and cut median triage time from hours to minutes.

Fintech · 2024
Audit-ready before the deadline
A payments startup needed ISO 27001 controls in place ahead of a partner review. We mapped the gaps, staged the work, and the team passed on the first attempt.

Healthcare · 2024
Containing an intrusion in motion
A clinic group called us mid-incident. We isolated the affected segment within the hour, preserved the evidence, and restored clean systems without paying anyone.

Retail · 2023
Cutting standing access by 70%
An e-commerce group had years of accumulated permissions. We rebuilt access around roles, enforced multi-factor sign-in, and removed the dormant accounts attackers love.

What clients report
“Our alert backlog dropped from roughly 400 a week to fewer than 30 that actually needed a person. The team finally trusts the dashboard.”
“They walked us through the ISO 27001 work in plain language and staged it so engineering never stalled. We passed the partner review on the first round.”
Common questions
Before you reach out
Do you replace our internal IT team?
No. We work alongside the people you already have. Most of our clients keep their IT staff focused on running the business while we own monitoring and response — the part that needs round-the-clock attention.
How does this compare to hiring in-house analysts?
A 24/7 internal team usually means five or more full-time hires plus tooling. A managed program gives you the same coverage as a shared cost, with a defined scope you can scale up or down as the business changes.
Are you registered to operate in Brazil?
Yes. Vantyr Security is registered in São Paulo (CNPJ 42.318.557/0001-09) and our engagements are governed by Brazilian law, including the LGPD framework for personal data.
What happens during an active incident?
A named analyst takes ownership immediately. We contain the affected systems, preserve evidence for any later review, and keep your leadership informed with a single, factual timeline rather than scattered updates.
How quickly can monitoring begin?
For most environments, initial coverage is live within two to three weeks. The mapping stage comes first so the alerts we turn on are tuned to your systems from day one.
Do you work with smaller companies?
We do. The program is sized to the operation — a thirty-person fintech and a national retailer get the same discipline, scoped to what each actually needs.
