AI-native cybersecurity, offensive and defensive
We bring together offensive, defensive, compliance and enablement in one place — with AI accelerating the work and the critical judgement always human. We sell control, not fear.
See what no one sees. Act at the exact point.
JustCyber brings together, in one place, what most companies have to source from several vendors: the offensive side (test and prove), the defensive side (monitor and respond), compliance (LGPD, ISO 27001, SOC 2) and training — with AI accelerating recon, triage and reporting.
Our idea is Precise Vigilance: seeing what no one else sees and acting at the exact point, with the calm of being in control. We sell control, not fear.
- 01
Offensive
Test and prove: Pentest, Red Team, adversary emulation.
- 02
Defensive
Monitor and respond: 24/7 SOC/MDR, DFIR, threat hunting.
- 03
Compliance
LGPD, ISO 27001, SOC 2 and PCI — from assessment to audit.
- 04
Enablement
Our own Academy to build and train security teams.
[ — ] · Our way
Offensive and defensive at the same table, AI on the heavy lifting and the critical judgement always human. That is how you spot it early and act at the right point.
A closed method, from first contact to delivery
Serious security is not improvised. Every engagement follows a predictable cycle — so you know what to expect at each stage, with evidence and regulatory support when needed.
Every engagement starts under a mutual NDA. Client confidentiality is the rule, not the exception.
- 01
Contact and NDA
Every conversation starts under a mutual NDA. We understand the scenario, the risk and the outcome you need.
- 02
Scope and rules of engagement
We define target, window, limits and success criteria in writing. Nothing runs without authorisation.
- 03
Execution
The senior team leads the work — offensive, defensive or strategic — with AI accelerating recon, triage and reporting.
- 04
Evidence and report
We deliver findings with proof, impact and prioritisation, at OSCP/CREST standard, in both technical and executive language.
- 05
Remediation and verification
We support remediation and re-test. What was found becomes, where it makes sense, a detection rule in your environment.
- 06
Continuity
From a DFIR retainer to continuous SOC/MDR monitoring — the relationship continues for as long as there is risk to manage.
An incident in progress does not wait. Neither do we.
When the worst happens, improvisation is what gets expensive. Our DFIR follows a closed method, from activation to regulatory notification — to contain fast, understand deeply and get back online safely.
Initial triage within 60 min · 1–4h response SLA for retainer clients.
- 01
Activation and triage
You reach us through the emergency channel. The on-call team assesses the scenario and classifies severity within 60 minutes.
- 02
Containment
Isolation of affected systems, blocking of indicators of compromise and preservation of forensic evidence.
- 03
Forensic investigation
Analysis of logs, memory, disk and network to find the root cause, the real scope of the compromise and the attack timeline.
- 04
Eradication
Removing the adversary from the environment, fixing the exploited flaws, rotating credentials and hardening the weak points.
- 05
Recovery
Controlled restoration of operations, with heightened monitoring and validation that the environment is safe again.
- 06
Regulatory support
Support for notifying the data-protection authority and data subjects within the legal deadline, with a lessons-learned report so it does not happen again.
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.
- 01
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.
- 02
AI-native, human decision
AI accelerates recon, triage and reports; the critical response and the final judgment are always made by senior analysts.
- 03
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.
- 04
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.
