Cybersecurity AI · Building in Public

Sovereign AI for
Cyber Defence.
You Own the Stack.

NOCTRODEX (OPC) PRIVATE LIMITED builds AI for cybersecurity teams who cannot send sensitive environments to a third-party API. Our model line — Ghostmaster — is actively iterating under development, alongside security apps that run on your own infrastructure so clients control inference end-to-end.

Ghostmaster Status · under development

Built for the cyber perimeter.

Ghostmaster is Noctrodex’s model focus: cybersecurity reasoning and assistive workflows where data residency and air-gap options matter. Status: under development.

Intent

Cyber-first

Built for cybersecurity operators — research, defence, and authorised engagement workflows.

Deploy

Your environment

Target: customer-controlled GPU / on-prem stacks so sensitive engagements never require a public API hop.

Stage

Iterating

Training, eval, and tooling loops are ongoing. We publish milestones as they become real — not vapour claims.

Apps & software releases 3 licensed builds

Tools and version track.

Operator-facing security engines and software around Ghostmaster and on-prem stacks. Commercial engines available with account-based product licensing.

Install from npm — npm install -g @noctrodex/sast or @noctrodex/dast — then sign in from the app. The engine runs on your own host and scans from your own IP; nothing is proxied through us. Want pilot access? Contact us — we stage releases only after the artifacts exist.

How we work 3 stages

From model to machine.

01

Model iteration

Ghostmaster cycles: data discipline, eval for cyber tasks, operator feedback.

02

Apps & tooling

Software interfaces and pipelines so analysts can use the model safely.

03

Engagement

Pilots and design discussions for security teams — contact us early.

Use cases 6 surfaces · cyber only

Cybersecurity only — for now.

Engagement surfaces for Ghostmaster and the apps & software releases track — software first, deployable on infrastructure you control.

SOC assist

Triage support, narrative drafts, and context gathering inside your controlled stack.

→ Operator console · analyst assist (roadmap)

Vulnerability research

Hypothesis generation and documentation aid for authorised research programmes.

→ Analyst assist toolkit · Ghostmaster evals (roadmap)

Digital forensics

Structured reasoning support for investigators working with sensitive evidence sets.

→ Operator workflows · offline-capable software (planned)

Purple team

Attack/defence narrative support under client rules of engagement.

→ Session-scoped operator tools (roadmap)

Secure code review

Assisted review workflows for engineering and AppSec teams.

→ Analyst assist / AppSec software surface (planned)

Air-gapped ops

Path to local models when the network boundary is non-negotiable.

→ Offline model releases · local deploy tooling (planned)
How use cases meet software

Each surface above is meant to land as a versioned app or software release — not as a metered public API. Track status under Apps & software releases; nothing is marked released until a real build exists.

SOC → console Research → toolkit Forensics → offline tools AppSec → review software Air-gap → local deploy

About Incorporated 27 Jul 2026

Who we are

The problem

Security work often collides with cloud-hosted LLMs: sensitive client data, engagement rules, and air-gap requirements make token APIs a non-starter. Teams still want serious AI assistance.

Our approach

NOCTRODEX (OPC) PRIVATE LIMITED focuses on cybersecurity AI — Ghostmaster under active development, and security apps and software on the roadmap — deployable on infrastructure clients control.

We are early-stage and honest about it: model iteration and product design are underway from Kolkata, West Bengal, India.

Where we are now

Incorporated 27 July 2026 as a One Person Company, ROC Kolkata — CIN U62010WB2026OPC288993. Pre-revenue, funded by the founder, no borrowings. Solo-founded and building in public on this site, focused on one sector — cybersecurity — with Ghostmaster and apps.
