Dutch Cybersecurity Startup Hadrian Raises $40M Series B to Expand AI Penetration Testing
Dutch AI security firm Hadrian secured $40 million in Series B funding to scale its AI-agent-based automated penetration testing services globally.
Dutch cybersecurity startup Hadrian announced it has completed a $40 million Series B funding round, bringing its total raised to $65 million. The company plans to use the new capital to expand operations in Europe, the Middle East, Africa, and the United States, as well as to increase investment in engineering and research.
Founded in Amsterdam in 2021, Hadrian uses AI agents to simulate attacker techniques, helping enterprises inspect systems and applications exposed to the public internet. Its External Attack Surface Management product, Atlas, continuously inventories assets and performs security tests when new assets are discovered or existing ones change. When new vulnerabilities are published, Atlas compares software versions to identify affected assets and tests whether the vulnerabilities can be exploited.
In March this year, Hadrian launched Nova, an AI-agent penetration testing product. Nova allows enterprises to specify the applications and scope for testing, with multiple AI agents attempting to chain different vulnerabilities to assess potential attack paths and their impact. According to Hadrian, most tests can be completed within 24 to 48 hours. UK cybersecurity media outlet Cyber Insider noted that while automated penetration testing helps identify issues, enterprises must still accurately manage external assets and control the testing process to ensure security risks are genuinely reduced.
