Terra Platform™ - External NetworkContinuous, agentic pentesting for external networks.Terra's agents continuously rediscover your real external attack surface, then chain exposed services and misconfigurations into validated exploits. Findings come with fixes, not just flags.

LabelTrusted by enterprise-grade security teams and providers

LabelDiscover, validate, and remediate external network assets.

Shadow IT, forgotten subdomains, a service stood up for a one-off project and never torn down: these accumulate faster than any static inventory can track. Terra's agents continuously rediscover your real external perimeter, fingerprint every exposed service, and chain misconfigurations into validated exploits, the same way a real breach starts.

Find what you don't know is exposed. Validate what an attacker could actually do with it.

Continuous Attack Surface DiscoveryAgents continuously rediscover your external perimeter: new subdomains, exposed services, forgotten infrastructure, and cloud assets. If it's reachable from the internet, Terra finds it before an attacker does.

Service and Protocol-Level ExploitationBeyond application logic, agents fingerprint exposed services and chain misconfigurations, weak protocols, and default credentials into real footholds — the adversaries actually begin network intrusions.

Closed-Loop RemediationEvery validated finding ships with prioritized guidance mapped to the exposed service or misconfiguration behind it. Automatic re-test confirms the fix worked, across every affected instance, not just the one you found.

Bridge to Other Attack SurfacesWhen an external foothold connects to a web app or an internal segment, Terra's agents follow it. Findings here don't stop at the network boundary, they lead to your other attack surfaces.

Terra Platform™One agentic Offensive Security platform. Every attack vector, continuously validated.

LabelGuardrails, not guesswork.

Real exploitabilityAutonomous agents continuously re-map your perimeter and validate exposure in minutes as new assets and services appear — the head start a quarterly or annual scan can't give you.

Governed by designAgents operate inside guardrails, with human judgment at every critical decision point before an exploit attempt runs against infrastructure you may not have even known was exposed.

Execution at scaleEvery discovered asset and every agent action is logged and traceable for audit readiness. Verified findings feed straight into your every-day remediation workflow.

LabelWhy teams choose Terra.

vs. ESAM / attack surface management toolsDiscovery-only tools tell you what's exposed. They don't tell you what's actually exploitable in your environment. Terra picks up where discovery stops, chaining exposed assets into confirmed attack paths.

vs. traditional vulnerability scannersScanners match exposed services against known CVEs. They don't prove an attacker could actually get in. Terra's agents chain findings into a validated exploit path before anything reaches your team

vs. manual point-in-time external pentest engagmentsA traditional external pentest scopes against an asset list that's already stale by the time testing starts, then goes quiet for a year. Terra rediscovers your perimeter continuously, so new exposure doesn't sit unnoticed until the next scheduled engagement.

vs. autonomous network-only pentest toolsAutonomous tools validate exploitability without human oversight and without visibility outside the network layer. Terra combines agentic discovery and exploitation with humans for safe testing, in the same platform as web apps AI systems, and internal networks.

FAQCommon questions about external network testingA brief description for this section.

What is external network penetration testing in Terra Platform?

External network pentesting identifies and validates exploitable exposure across internet-facing infrastructure — exposed services, open ports, and misconfigurations an attacker could reach without any internal access. Terra maps these assets continuously and chains discovered misconfigurations the way a real attacker would, rather than reporting them as isolated issues.

How is continuous external network testing different from an annual network pentest?

An annual network pentest is a snapshot — it reflects exposure on the day it ran and can be weeks stale by the time you get the report. Terra continuously discovers and re-validates external assets, so newly exposed services or misconfigurations are caught as they appear rather than at the next scheduled engagement.

Does external network testing just flag open ports, or does it validate real risk?

Terra validates exploitability rather than just flagging exposure. Agents chain discovered misconfigurations into realistic attack paths and confirm what's actually reachable and exploitable, so your team triages far less noise than a scan-only report produces.

How does remediation verification work?

Every validated finding comes with prioritized remediation guidance, and Terra automatically retests to confirm a fix actually closed the exposure — across every affected instance, not just the one that was manually checked.
