Terra Security, a cybersecurity company specialising in agentic-AI-powered penetration testing, has secured $30m in a Series A funding round.
The round was led by Felicis, with additional backing from Dell Technologies Capital, SVCI, and existing investors SYN Ventures, LAMA Partners (formerly FXP), and Underscore VC. This latest raise brings Terra’s total funding to $38m. The company also announced that Gerhard Eschelbeck, former Google chief information security officer, has joined its board of directors.
Founded to tackle the outdated nature of penetration testing, Terra Security combines a swarm of AI agents, which mimic the behaviours of ethical hackers, with a human-in-the-loop system to provide continuous testing. The firm says this approach offers organisations constant visibility into their vulnerabilities, addressing the limitations of traditional one-off penetration tests and purely automated tools.
The company intends to use the fresh capital to broaden its platform beyond penetration testing. Plans include expanding into AI-driven red teaming and providing greater enterprise attack surface coverage. Terra also aims to scale its R&D and product teams while growing its go-to-market presence to reach more organisations worldwide.
The firm has already gained momentum since closing its $8m seed round earlier this year. In that time, it launched its continuous penetration testing platform, won the 2025 CrowdStrike & AWS Cybersecurity Accelerator in collaboration with Nvidia, and secured multiple Fortune 500 clients and partners.
Terra Security said its platform focuses on “exploit-driven accuracy”, validating findings through real exploitation rather than hypothetical scoring. Results are also tied to an organisation’s business context, ensuring security teams can prioritise the most critical risks. The human oversight built into the system ensures accuracy and depth, while the AI swarm provides the scale and speed of automation.
The latest funding marks a clear signal that the market is ready for change, with security teams increasingly seeking a new era of offensive testing.
