Security in the Age of AI Transformation

Artificial intelligence is transforming how organizations operate—and redefining the cybersecurity landscape. Citadelo is at the forefront of this shift. We combine 14 years of ethical hacking expertise with advanced AI-powered security testing, helping you innovate without compromising security.

AI-Powered Penetration Testing
We integrate AI directly into our penetration testing processes. It accelerates reconnaissance, expands test coverage, and helps uncover more vulnerabilities in less time. Final assessment and validation, however, always remain in the hands of experienced ethical hackers.

Securing Your AI Systems
Are you deploying large language models (LLMs), AI agents, or generative AI solutions? We test them against prompt injection, model data leakage, jailbreak techniques, and adversarial attacks—and help you prepare for compliance with the EU AI Act.

Tested Technologies

Hacking is our passion, which we have been deepening daily for over 14 years. Thanks to this expertise, we are able to test most technologies with the highest quality. We continuously evolve our methodologies and leverage AI throughout the testing process to increase coverage and identify more vulnerabilities in less time. The final verdict, however, always comes from a skilled ethical hacker.

Securing Artificial Intelligence and LLM Systems

Artificial intelligence is transforming the way organizations operate, but it is also creating entirely new attack vectors. Large language models (LLMs), AI agents, and integrations with internal systems introduce risks that traditional penetration tests often fail to address, including:

  • Prompt injection
  • Model and context data leakage
  • Security guardrail bypass
  • Adversarial manipulation attacks

At Citadelo, we test AI systems with the same rigor we apply to web applications, APIs, cloud environments, and infrastructure. We identify weaknesses before attackers do and help you demonstrate compliance with regulatory frameworks such as the EU AI Act, NIS2, and DORA.
