Question 1

What is Terra Security?

Accepted Answer

Terra Security is an agentic offensive security platform for continuous penetration testing, built from the start around a human-in-the-loop architecture. A coordinated swarm of dozens of fine-tuned AI agents continuously scopes environments, discovers attack surfaces, generates hypotheses, and validates vulnerabilities, running thousands of tests tailored to each organization's business context and risk profile and adapting in real time as applications change.

When agents hit their limits, Terra's agentic gateway brings human pentesters into the same agentic workflow with full context preserved, combining the accuracy, safety, and depth of expert testers with the scale of automation; the same gateway lets MSSPs supervise continuous AI-driven testing across client environments.

Terra Portal, launched March 2026, is an agentic desktop application serving as the execution layer for testers overseeing AI-driven testing in live production, which the company says cuts the vulnerability discovery-to-fix cycle from an industry average of nearly three months to hours without sacrificing safety or compliance.

In May 2026 Terra unified web application, AI system, and network infrastructure testing under one platform, positioning itself as the only continuous agentic platform validating exploitable risk across multi-vector attack chains spanning all three surfaces. Reports deliver proof of exploitability with remediation prioritized by business impact.

Founded in 2024, Terra raised $38M within roughly a year ($30M Series A led by Felicis with Dell Technologies Capital and SVCI), serves Fortune 100 clients, added former Google CISO Gerhard Eschelbeck to its board, and became the first AWS Partner to achieve the Security Competency for Autonomous Security Validation. Within the offensive cluster, Terra is the human-in-the-loop, multi-surface entrant alongside XBOW's bug-bounty-proven external testing and Horizon3's production-safe internal pentesting.

Question 2

How much does Terra Security cost?

Accepted Answer

No published rate card; continuous penetration testing sold as service-as-software through sales, scaled to the size and complexity of the application landscape.

Question 3

What does Terra Security integrate with?

Accepted Answer

Continuous agentic testing spans web applications, AI systems, and network infrastructure under one platform, validating multi-vector attack chains across surfaces. Dozens of fine-tuned AI agents run thousands of tests tailored to the organization's business context and risk profile, and the agentic gateway lets human testers and MSSP supervisors operate inside the same agentic workflow with full context preserved. First AWS Partner to achieve the Security Competency for Autonomous Security Validation (March 2026).

Question 4

Who is Terra Security for?

Accepted Answer

Fortune 100 and Fortune 500 enterprises replacing point-in-time pentests, security teams needing continuous multi-surface offensive validation, MSSPs supervising AI-driven testing across client environments, organizations testing AI systems alongside web and network surfaces

Question 5

What are the best alternatives to Terra Security?

Accepted Answer

Based on documented capability coverage across the Agentic Index 14 point taxonomy, the closest alternatives to Terra Security among security and SOC agents are HiddenLayer, Lasso Security, Linx Security, Noma Security. Each is graded on the same public evidence, and no vendor pays for placement.

Question 6

Does Terra Security give you tracing and observability into agent runs?

Accepted Answer

Full under the Agentic Index verification standard. Terra Security publishes public evidence of tracing, observability and audit logging into agent runs, so a team can see what an agent did and why. Evidence basis: Reports deliver proof of exploitability and potential consequences with remediation prioritized by actual business impact, and full context is preserved across the agent-human workflow, Tracxn profile and Terra materials 2026-07-22. Graded from public evidence only against the Agentic Index 14 point capability taxonomy. No vendor pays for placement.

Question 7

Does Terra Security require human approval before an agent acts?

Accepted Answer

Full under the Agentic Index verification standard. Terra Security publishes public evidence of human approval steps and guardrails, so an agent action can be held for review before it executes. Evidence basis: Human-in-the-loop is the platform's signature architecture: the agentic gateway lets human testers operate inside the same agentic workflow with full context, Terra Portal serves as the tester execution layer, and MSSPs supervise continuous. Graded from public evidence only against the Agentic Index 14 point capability taxonomy. No vendor pays for placement.

Question 8

Does Terra Security support MCP and tool calling?

Accepted Answer

Partial under the Agentic Index verification standard. Terra Security publishes some public evidence of tool calling and API or SDK extensibility, but narrower than full Model Context Protocol (MCP) support as defined by the Agentic Index taxonomy. Evidence basis: The agentic gateway is an extensibility surface letting human testers and MSSP supervisors plug into the agentic workflow; a public API or SDK was not retrieved, QA Financial and MSSP Alert 2026-07-22. Graded from public evidence only against the Agentic Index 14 point capability taxonomy. No vendor pays for placement.
