CyberShield · On-device AI data protection

Stop company data leaking into AI tools, and scams reaching your people.

CyberShield checks what people paste, upload and click, and stops the risky moments before anything is sent. Every check runs on the user's own device, so nothing is sent out to be inspected.On-device AI security suite · browser, desktop, VS Code and network proxy

The problem

The risk sits in the moment someone types, pastes or clicks.

AI is now part of every workday, and every scam. Most security tools watch files and network traffic, so they miss that moment. Four risks pass through the same laptop or phone.

01Company data pasted into AI tools

AI data loss prevention

Source code, customer records and passwords typed or pasted into AI chat tools.

02Hidden instructions that hijack AI assistants

Prompt injection

Pages, files and tools carry instructions that take over AI assistants and agents.

03AI apps nobody approved

Shadow AI discovery

Teams adopt AI and SaaS apps faster than IT can review or approve them.

04Scams written by AI

Phishing and payment fraud

Fake invoices, phishing and impersonation arriving by email and WhatsApp.

How it works

Checked on the device, in five steps.

01You act

Paste a prompt, upload a file, open a link or commit code.

02We intercept

At the point of action, before anything is sent.

03The engine decides

Three layers check it, all on the device.

04We act

Allow, redact, warn or block, as your policy says.

05We record

Dashboard, security score and audit trail.

Four weeks from scope to a yes-or-no decision.

We start in warn-only mode with a small pilot group, then measure what was caught against criteria you set.

Week 0Scope

Agree goals and success criteria, pick the pilot users, name a sponsor.

Week 1Deploy

Roll out the extension, desktop app and VS Code in warn-only mode.

Weeks 2–3Run

Watch live activity, tune rules each week, test blocking with one team.

Week 4Review

Findings report, results against your criteria, and a rollout plan.

Run a CyberShield proof of concept with your team.

Pick “AI data leaks and scams (CyberShield)” in the pilot form and we will scope it with you.
