Terra Security, a company pioneering the use of agentic AI for continuous penetration testing, has secured $30 million in Series A funding. The round was led by Felicis, with participation from Dell Technologies Capital, SVCI, and existing backers SYN Ventures, LAMA Partners, and Underscore VC. This brings Terra’s total funding to $38 million.
Terra was founded to address the limitations of traditional penetration testing, which have remained essentially unchanged for decades. Many organizations still rely on manual, point-in-time tests that are costly, slow, and quickly outdated. Automated tools, while faster, often fail to replicate the tactics of real attackers or provide actionable insights at scale. This leaves security teams with blind spots and vulnerabilities that can be exploited before they are addressed.
The company’s platform combines a network of specialized AI agents—each designed to think and act like an ethical hacker—with human oversight to test an organization’s entire attack surface continuously. Every finding is validated through real exploitation rather than theoretical scoring, and results are tailored to each organization’s specific risk profile. The system runs year-round, ensuring that vulnerabilities are identified and addressed quickly. The human-in-the-loop approach ensures accuracy and depth, while the AI agents deliver the scalability of automation.
Since raising its $8 million seed round just months ago, Terra has launched its platform, won the 2025 CrowdStrike & AWS Cybersecurity Accelerator in collaboration with Nvidia, and expanded its customer base to include multiple Fortune 500 companies. These milestones signal strong market demand for a new era of offensive security testing.
With the new funding, Terra plans to expand into AI-driven red teaming, broaden its coverage of enterprise attack surfaces, expand its research and product teams, and scale its global market presence. The company believes it is only beginning to explore the potential of combining AI agents with human expertise to protect critical systems worldwide.
New board member: As part of the announcement, the company also welcomed Gerhard Eschelbeck, former Chief Information Security Officer at Google, to its board of directors.
