The team
This guide comes from CyPro Consulting Ltd, a consultancy in the UK that works only on cyber security. Its consultants wrote it for managers and technical leads weighing up how far an AI tool can be trusted with their data.
Purpose
Why it exists
Guidance on prompt injection sits in government blogs, standards documents, vendor posts and press reports. This site gathers it into a single readable account. If the published sources do not support a point, it is left out.
Accuracy
How it is checked
Every factual statement carries a link to its origin, and the sources page names the publishers behind them. Pages are reviewed whenever one of the main publications changes, and the review date appears beside the home page headline.

Need a hand planning for this?
Understanding the change is one job. Working out what it means for your systems, your suppliers and your roadmap is several more. CyPro's consultants can take any of them on.

A senior security lead who advises the board on what to fix first, what to accept and what to tell customers, and owns the decision record.

Hardening and segmentation
Our consultants put the controls in place that limit the damage when something is missed: firewall rules, network isolation and tighter admin access.

Penetration testing
A focused test of your systems and the controls around them, so you know they hold before an attacker finds out for you.

Vulnerability scanning
Find every internet-facing system you run, including the forgotten ones, and see which are still on a vulnerable build.

24/7 security monitoring
Our SOC analysts watch your systems day and night for the signs of an attack in progress: unexpected processes, new outbound connections, logins that do not fit.

Incident response

Want a plan for your organisation?
Prompt injection only shows up when someone tries it against your own tools. Penetration testing can probe the AI features you run or build, to see what a hostile instruction could reach.
