Ranking of the Top Ten AI-Powered Penetration Testing Firms in 2025
In the rapidly evolving world of artificial intelligence (AI), the need for robust security measures has become increasingly crucial. A number of companies are stepping up to tackle the unique challenges posed by Large Language Models, offering AI red-teaming services to identify vulnerabilities in homegrown AI applications.
One such company is CalypsoAI, whose flagship product, the Inference Red-Team solution, automates the discovery of vulnerabilities through real-world attack simulations. By mimicking potential threats, CalypsoAI helps organizations to proactively test and defend against attacks on their AI models.
Another key player in AI security is Mindgard, a leader in AI Security Testing, a category recognized by Gartner as an emerging innovation. Mindgard offers a comprehensive platform for securing GenAI applications, with solutions for automated red teaming during development and real-time runtime protection.
Lakera, another specialized AI security company, has made significant contributions to the OWASP Top 10 for LLMs (2025) and the AI Vulnerability Scoring System, demonstrating its deep involvement in shaping the industry's security standards. Lakera's platform provides a comprehensive solution for securing GenAI applications.
HiddenLayer, a company focused on MLSecOps, the practice of integrating security into machine learning operations, also plays a crucial role in the AI security landscape. By ensuring the security of AI systems from the ground up, HiddenLayer empowers organizations to adopt AI with confidence.
Robust Intelligence is another company that specializes in making AI models resilient and trustworthy, addressing the unique fallibility of generative AI systems.
However, traditional penetration testing methods are insufficient to secure AI systems. AI systems are vulnerable to a new class of attacks that can corrupt data, manipulate behaviour, or exfiltrate sensitive information. To combat these threats, HackerOne offers a managed service for AI red teaming, leveraging its vast community of security researchers to find and fix AI vulnerabilities.
The three leading companies in the AI penetration testing industry offering automated, realistic red-teaming capabilities in 2025 are not explicitly named in the available search results. However, Palo Alto Networks (Unit 42) is noted for simulating real attacks in penetration tests, SySS GmbH specializes in red teaming and penetration testing services, and Obsphera provides high-security software solutions with compliance certifications, which may imply relevance to this field.
In conclusion, as AI becomes more integrated into our daily lives, the importance of AI penetration testing cannot be overstated. In 2025, AI penetration testing is crucial for ensuring the security, reliability, and ethical use of AI. By adopting AI red-teaming services, organizations can proactively test and defend against potential threats, ensuring the continued success and trustworthiness of AI systems.
