Terra Platform™ - Internal NetworkContinuous, agentic pentesting for internal network infrastructure.Terra's agents trace lateral movement and privilege escalation across your internal network, then help close each path with a verified fix. Now in limited preview with select design partners.

LabelTrusted by enterprise-grade security teams and providers

LabelPurpose built pentesting for what's behind your perimeter.

Terra's internal network capabilities extend the same agentic, human-on-the-loop model it uses for web, external network, and AI testing inward: mapping segments, chaining misconfigurations, and validating how far an attacker could actually move after a single compromised credential or device.

One foothold is all it takes. Test how far it actually goes.

Internal Network CoverageUnified Offensive Security across web, network, AI, and internal infrastructure. Agents chain findings across surfaces the way an attacker would after breaching the perimeter, instead of testing internal exposure in isolation.

Lateral Movement ValidationAgents don't stop at a single foothold. They test how far that access actually travels: segmentation boundaries, shared credentials, and privilege escalation paths that turn one compromised endpoint into a domain-wide incident.

Closed-Loop RemediationEvery validated finding ships with prioritized guidance for closing the specific credential, segmentation gap, or misconfiguration that made the path possible. Automatic re-test confirms the full lateral-movement path is actually closed.

Truly Enterprise-GradeOne agentic platform for internal network, external network, web apps, and AI systems. No separate internal pentest vendor needed, and no separate report to reconcile. Every surface runs through the same guardrails and audit trail, so scaling coverage doesn't mean scaling vendor overhead.

Terra Platform™Discover the risk. Validate it's real. Remediate it fast.

LabelMachine speed. Human judgment. No compromise.

Real exploitabilityAutonomous agents with white-box visibility detect internal attack surface changes and validate exposure in minutes, not at the next scheduled internal assessment.

Governed by designAgents operate inside guardrails, with human judgment at every critical decision point before a lateral-movement or privilege-escalation attempt runs.

Execution at scaleExecution records and verified findings feed straight into your every-day remediation workflows and audit readiness.

LabelWhy teams choose Terra.

vs. autonomous-only internal network toolsAutonomous tools test lateral movement without the safety of human oversight and without visibility into web apps or AI systems. Terra combines agentic internal network testing with human confirmation, in the same platform as everything else you test.

vs. internal network vulnerability scannersScanners flag misconfigurations and open shares. Terra's agents chain them into a confirmed lateral-movement or privilege-escalation path, so you know what's actually reachable, not just what's technically wrong.

vs. manual point-in-time internal pentest engagmentsA traditional internal assessment is a snapshot of lateral-movement risk on the day it ran. Terra re-validates exposure as your internal environment changes, so drift and new systems don't sit undetected until the next scheduled engagement.

vs. siloed internal network pentest vendorsWhen internal and external network findings live in separate tools, the full attack chain — perimeter breach to lateral movement to domain compromise — never gets mapped end to end. Terra connects it them in one place, alongside web applicaitons and AI systems.

FAQCommon questions about internal network pentesting

What is internal network penetration testing?

Internal network pentesting validates what an attacker could do once they're already inside the network — through a compromised credential, a phished device, or an insider — rather than testing what's reachable from the outside. It answers a different question than external network testing: not "can someone get in," but "how far could they get once they're in."

How is internal network testing different from external network testing?

External network testing covers internet-facing assets and services. Internal network testing assumes a foothold already exists inside the network and validates lateral movement, privilege escalation, and how far an attacker could pivot from that starting point toward critical systems.

How does continuous internal network testing differ from a traditional internal pentest?

A traditional internal pentest is a scheduled, point-in-time engagement — a snapshot of lateral-movement risk on the day it ran. Continuous internal network testing re-validates exposure as the internal environment changes, so new lateral-movement paths introduced by configuration drift or new systems don't sit undetected until the next scheduled engagement.
