External Penetration Testing. From $99 per target.
Test your internet-facing attack surface the way an attacker would. 14 professional tools map your perimeter, then autonomous AI agents run a real external penetration test and prove what is exploitable. One report per target, in hours, starting at $99 each - with volume pricing as your scope grows.
What an external penetration test covers
Everything reachable from the public internet - the perimeter an outside attacker probes first.
Subdomain & host discovery
Subfinder and HTTPX enumerate subdomains and live hosts to map the internet-facing footprint an attacker would see - including forgotten and shadow assets.
Ports, services & TLS
Naabu fingerprints exposed ports and services; TestSSL checks certificates, protocols, and cipher configuration on every listener.
Web apps & APIs
OWASP ZAP, Nuclei, Nikto, and FFUF test externally reachable web applications and REST/GraphQL APIs against the OWASP Top 10 and known CVEs.
Exploit validation
Paladin AI agents attempt to exploit what the tools flag - confirming real, reachable risk with proof-of-concept evidence instead of a list of maybes.
External vs. internal penetration testing
External penetration test
Starts from the public internet with no prior access. Targets your perimeter - domains, exposed services, web apps, and APIs - the way an opportunistic attacker would. This is what TurboPentest runs.
Internal penetration test
Simulates an attacker already inside the network - a malicious insider or a foothold from phishing - testing lateral movement and privilege escalation. Usually run after the external perimeter is solid.
Traditional external pentest: $4,000 - $25,000 per target
TurboPentest external pentest: from $99 per target
A full external penetration test with proof-of-concept evidence, at a fraction of the cost and turnaround. Flat $99 per target with volume discounts as scope grows. See all pricing tiers.

External penetration testing FAQ
What is external penetration testing?
External penetration testing assesses the systems an attacker can reach from the public internet - your domains, subdomains, exposed services, TLS configuration, web applications, and APIs. The goal is to find and safely exploit weaknesses on your internet-facing attack surface before a real attacker does. TurboPentest runs the full external pentest with 14 industry-standard tools plus autonomous AI agents.
What is the difference between external and internal penetration testing?
External penetration testing starts from the public internet and targets your internet-facing perimeter with no prior access. Internal penetration testing simulates an attacker who is already inside the network - a malicious insider or a foothold from phishing. Most teams start with external testing because that is where opportunistic attacks begin. TurboPentest focuses on the external attack surface.
What does an external penetration test include?
Subdomain and host discovery, port and service scanning, TLS/SSL configuration review, web application and API testing against the OWASP Top 10, and exploit validation with proof-of-concept evidence. You get a report with severity, CVSS scores, remediation guidance, and a signed attestation letter.
Is this an external infrastructure or network penetration test?
Yes. The external pentest covers your internet-facing network and infrastructure - exposed hosts, ports, and services - alongside the web applications and APIs running on them. Connect a GitHub repository to add white-box source-code analysis for deeper coverage.
How much does an external penetration test cost?
TurboPentest external penetration testing starts at $99 per target for the Audit-Ready tier, versus $4,000 to $25,000 per target for a traditional external pentest engagement. Pricing is per target (a domain, host, or IP), with no minimums or contract, and volume discounts kick in at 10+ targets. Deeper tiers (Threat-Hunt $299, Adversarial-Depth $699) add more AI agents and longer analysis for higher-risk targets.
How often should you run an external penetration test?
At least annually and after any change to your internet-facing footprint - a new service, subdomain, or release. Because TurboPentest returns results in hours from $99 per target, many teams run an external pentest every release or continuously in CI/CD instead of once a year.
Build your external pentest quote
Most attack surfaces are more than one target. Size yours below - flat $99 per target, volume discounts as it grows - then start with your primary domain.
A target is one domain, host, or IP. Most external attack surfaces have several - price them all at a flat $99 each.

A traditional external pentest of this scope runs $20,000 - $125,000. No minimums, no contract, results in hours.
