About Terra Security

Terra Platform™ covers web, API, AI, external network, and internal network pentesting. Terra Security unifies web and internal applications, APIs, AI applications (LLMs, MCP servers, AI agents, AI-serving APIs), and external and internal network infrastructure into one platform. Terra lets customers scope all relevant attack surfaces in a single engagement setup. Terra supports tracing a path from a network exposure to an application compromise.[1][3][4][13]

Terra agents generate and test thousands of hypotheses, called Signals, against the customer environment, and only confirmed, exploitable findings reach the customer team. Terra agents safely attempt to exploit each hypothesis against the live environment to prove whether the risk is real. Terra combines agents and humans in a double verification layer before anything ships to the customer queue. Terra agents are trained on business context and code. Terra prioritizes findings by exploitability and business impact, not generic severity scores.[3][5]

The Terra Offensive Research Collaboration Hub (TORCH) lets users work directly with Terra agents and control every step of the process.[3]

Terra Platform™ runs continuous, agentic pentesting tied to the CI/CD pipeline. Terra integrates with the CI/CD pipeline and code repositories, in read-only or white-box mode. Terra agents identify what changed and map which parts of the live attack surface the change touches or exposes. Every meaningful code change triggers targeted re-testing automatically. Terra Platform™ continuously watches for changes that affect the live attack surface, including deployments, config drift, and new services. Validated findings ship as fix PRs with remediation recipes, and agentic testing re-runs against the affected surface with no re-scoping. Terra includes auto-remediation PR generation, which can propose a fix directly. Terra creates and updates tickets in Jira, Linear, or ServiceNow with the finding details.[3][6][7][8]

Terra produces audit-ready reports signed by certified pentesters. Terra reports map to SOC 2 Type II (held) and are accepted by auditors for ISO 27001, PCI-DSS, and HIPAA engagements. Certified pentesters validate and sign off on every Terra finding. Terra reports cover web, API, AI systems, and internal and external network findings in a consistent format. Terra reports are available immediately, on demand. Terra's methodology and individual tester credentials align with CREST standards. Terra delivers human-signed, audit-ready reports on a continuous cadence, with flat annual pricing.[3][9][10][11]

Terra Platform™ runs as multi-tenant SaaS, as a single-tenant instance in the customer cloud account, or on the customer hardware, and the price follows the attack surfaces included. Terra offers multi-tenant SaaS, single-tenant isolated cloud, or on-premises and air-gapped deployment for FedRAMP-class requirements. Terra provides heatmaps, trend lines, and program-level metrics for board reporting. Terra produces continuous, human-signed pentest reports for GRC teams. Terra Security describes its mission as continuous Offensive Security for enterprises, combining AI with human judgment and business context.[1][2][6][8][9][10][12][13][14]
