AI CyberSecurity: Guardrails, Sanitization, Proxies and Prevention

I design architectures for cybersecurity applied to AIdesigned to protect your models, your data and your users against emerging threats. Each solution is preventive, explainable and scalableto guarantee reliable, responsible AI that complies with data security standards & legislation (RGPD, GDPR).

Guardrails (AI)

  • Strict control of model inputs and outputs.
  • Definition of business, ethical and regulatory rules.
  • Reduced risk of hallucinations and unwanted behavior.

 

Sanitization of data and prompts

  • Cleaning and validation of user entries.
  • Detection of prompt injection attacks or adversarial data.
  • Prevent leaks of sensitive information.

 

Proxy and model isolation

  • Installation of secure proxies between users and models to filter, log and control flows.
  • Isolation of execution environments (sandboxing) to limit the impact of an attack.
  • Clear separation between application layers, AI models and external tool calls (MCP)

 

IA endpoint security

  • Strong authentication and access management.
  • Rate limiting to prevent abuse.
  • Complete logging and auditing of API calls.

 

Prevention

  • End-to-end encryption of sensitive data.
  • Regular rotation of API keys and secret management.
  • Regular penetration tests and audits to identify vulnerabilities with external service providers.
  • Update and retrain models to close vulnerabilities.

 

This approach enables me to deliver AI solutions secure, robust and compliantWe offer you a complete range of solutions, capable of withstanding current and future threats, while remaining aligned with your strategic objectives.
