Capability 06 of 10Secure, governed, compliant
Secure the product, the data and the AI, and prove it to auditors.
Cybersecurity & AI Trust secures your product, data and AI systems, and builds the governance that keeps you compliant. Threat modelling, secure delivery, cloud and identity security, AI red-teaming and audit-ready evidence, run as one programme.
Illustrative attack-surface radar. Four zones surround your platform: perimeter, application, data, and AI and agents. Seven assets are plotted as findings, including an admin panel, a public API, a storage bucket, a vector store and a support agent. Beside it, a findings feed lists detections by severity, critical, high or medium, and marks two of them contained.

- SOC 2 — Trust Services Criteria

TM-01Exposure
AI widened the attack surface. Most controls were built for forms and APIs.
A language model reads text from customers, documents, web pages and other tools, and some of what it reads can act. Four new kinds of exposure now sit beside the ones your security programme already covers.
Untrusted input and actions to control
- Form fields
- API parameters
- File uploads
- Headers & cookies

E1 · New exposure
Prompts are input now
Anything the model reads can carry instructions: a chat message, a PDF, a web page, an email signature. Input validation has to cover natural language, not just form fields.
ControlInput classifiers and content isolationLLM01
-
E2 · New exposure
Agents have write access
An agent that can refund, email or edit records turns a manipulated sentence into an action. What the agent is allowed to do matters more than which model it runs.
ControlTool allow-lists, scoped tokens, human approvalLLM06

E3 · New exposure
Vector stores hold sensitive text
Embeddings and retrieved chunks carry contracts, tickets and personal data, often without the permissions of the system they were copied from.
ControlTenant filters enforced at retrievalLLM08LLM02

Shadow AI arrives by browser tab
Teams paste customer data into unapproved assistants and extensions. What is not in the inventory cannot be assessed, approved or monitored.

TM-02Defence in depth
Defence in depth, layer by layer.
No single control holds on its own. Each layer assumes the one outside it will fail, and each has named controls, a way to prove they work and the tools that run them.
Layer 1 of 6 · 4 controls
Identity
Every person, service and agent proves who it is, and gets only the access the task needs.
- Single sign-on with phishing-resistant MFA (passkeys, FIDO2) for staff and adminsA.8.5

Sensitive data is encrypted, minimised and masked, and the keys are held apart from the data.

TM-03Red-team range · interactive
Try to break the assistant. See which layer stops it.
A support assistant for Your company can look up orders, search help articles and issue refunds. Pick an attack, switch defence layers off and launch it. No single layer catches everything; layers in sequence, tested on every change, do.
Interactive red-team range. Choose one of five attacks, switch any of five defence layers on or off, then press Launch attack. The result says which layer stopped the attack, or that it reached the customer and opened an incident, with the OWASP and MITRE ATLAS references, and adds a line to the log. A matrix below shows which layers stop which attacks.
