Shadow AI
Assistants, extensions and agents adopted by teams without going through IT. No inventory, no control over which data ends up where.
When AI enters a company it brings data, access and autonomy. Fortgale integrates AI security technologies into the MDR and SOC cycle: alerts are handled 24·7·365 by the analysts in Milan, and posture is reported in the Fortgale Defence Platform.
They are two distinct problems. Defending with AI means using it in SOC and MDR work: we cover it in AI in cyber defence. Protecting AI means securing the systems the company adopts: that is the subject of this page.
Four ways an AI system becomes an attack surface or a data leakage channel.
Assistants, extensions and agents adopted by teams without going through IT. No inventory, no control over which data ends up where.
A user, but also a document, a web page or an email, can carry instructions that the model executes as if they were legitimate.
Personal data, code and confidential documents pasted into external tools, or retrieved by an assistant with permissions that are too broad.
An agent with more access, tools and autonomy than its task needs: if it deviates, it deviates with the keys in hand.
A general integration model, valid for the technologies the company has already adopted as well as for those we choose with you.
A census of the AI systems in use, official or not, and of the data they touch.
Controls on what goes into and comes out of the models: hostile instructions, sensitive content, out-of-policy responses.
Protection of the data that reaches the models, internal or external, and of the sources assistants retrieve information from.
Monitoring of what agents do, with which identities and which permissions.
Permissions, classification and policies on the environment the assistant works in.
Applications built in house on top of a model: inputs, integrations, access to data and tools.
Fortgale selects and integrates third-party AI security technologies into the defence cycle. As with MDR built on the customer's technology, the technology can be the one already in use or one chosen by Fortgale, and the SOC operates it: alerts are handled 24·7·365 by the analysts in Milan, with the same method as MDR and SOC. The posture of AI systems is reported in the Fortgale Defence Platform: the deliverable is the dashboard in the portal.

A table of references, not of promises: Fortgale does not attest compliance or promise certifications. It provides technical evidence that feeds your governance process. The AI Act timetable, the OWASP entries and a checklist are in OWASP Top 10 for LLM 2026, MITRE ATLAS and the AI Act.
| Reference | What it is for |
|---|---|
| Regulation (EU) 2024/1689 · AI Act | The European framework on AI. Article 15: accuracy, robustness and cybersecurity for high-risk systems. Annex III from 2 December 2027. |
| ISO/IEC 42001 | Standard for an AI management system. A governance reference: our technical evidence can feed it. |
| NIST AI RMF | AI risk management framework (Govern, Map, Measure, Manage). Useful to structure the assessment. |

On 7 July 2026 the ECB wrote to significant banks about AI-enabled cybersecurity threats, and the ESAs have set out their expectations on AI inside the DORA framework: both are read in cybersecurity for banking and finance. The technical side described here is the material the evidence comes from. The evidence we provide is technical; the assessment of adequacy and compliance with the AI Act remain with the board and the control functions.
Whoever promises to eliminate prompt injection promises something nobody can deliver today. Our line is different: reduce agent permissions to what is necessary, check prompts and responses, watch what the agent does and contain within minutes when it deviates, with the same detection and response cycle we use on the rest of the defence.
Shadow AI is the use of generative AI tools, assistants, extensions and agents that the company has not inventoried, approved or brought under control. The risk is twofold: company data leaving for external models, and systems acting with access that nobody governs. It starts with an inventory: you cannot protect what you do not know you have.
No. As long as a model handles instructions and data in the same text channel, hostile content can influence it. It is detected and contained: agent permissions are limited, prompts and responses are checked, what the agent does is monitored, and the response is fast when it deviates. That is the Fortgale line: detect and contain, not promise to eliminate.
It depends on how the environment it works in is configured. Copilot works with the user's permissions: if document permissions are too broad, the assistant makes it easier to find what was already accessible by mistake. What matters is permissions, data classification, Microsoft 365 policies and monitoring of use.
For high-risk AI systems, Article 15 of Regulation (EU) 2024/1689 requires accuracy, robustness and cybersecurity throughout the lifecycle. The timetable applies the obligations for Annex III systems from 2 December 2027. If you neither develop nor integrate high-risk systems, your obligations are different: check your role (provider, deployer) before assuming the article applies to you. The updated timetable is in the guide OWASP Top 10 for LLM 2026, MITRE ATLAS and the AI Act.
