[ — ] · Precise Vigilance
Security is not about fear. It is about control — seeing what no one else sees and acting at the exact point before it becomes a crisis.
Our services
Defence and strategy for those who cannot take risks
One team, from the attack to the boardroom. Pick the front — offensive, defensive or strategic — and see how we run it.
-
-
Red Team
A full attack simulation — digital, human and physical — against a real objective, testing people, processes and technology.
-
Adversary Emulation (APT)
We replicate the documented tactics of a group relevant to your sector to validate your defences against it, in practice.
-
SOC & MDR 24/7
24/7/365 threat monitoring and response, with AI on triage (L1/L2) and senior analysts on the critical response.
-
DFIR — Incident Response
When the incident hits: we contain, investigate, eradicate and recover — including breach notification to Brazil's data-protection authority (ANPD) and to affected data subjects.
-
Proactive Threat Hunting
Active hunting for threats that already slipped past the controls: it assumes something got in and looks for the evidence.
-
Compliance & LGPD
Assessment, implementation and audit prep: LGPD, ISO 27001, SOC 2 and PCI-DSS — with AI-generated policies.
-
DevSecOps
Security built into the development cycle, from design to production — SAST, DAST, SCA, IaC and containers.
-
vCISO — CISO as a Service
A senior security executive on demand, driving strategy, risk, compliance and the relationship with the board.

Why JustCyber
Trust is proven by operating, not by logos
We work under NDA and never expose clients. Instead of logos, we show how we operate — that is what earns trust.
-
Offensive and defensive on the same team
The people who attack and the people who defend talk to each other. What the Red Team finds becomes a detection rule in the SOC — no handing you between vendors.
-
AI-native, human decision
AI accelerates recon, triage and reports; the critical response and the final judgment are always made by senior analysts.
-
End-to-end compliance
From assessment to audit across LGPD, ISO 27001, SOC 2 and PCI — with regulatory support during incident response, including breach notification.
-
From SMB to enterprise
Tailored services and a product platform that becomes available incrementally, as each module matures.
We work under NDA. We do not expose clients or disclose engagements.
