AI-powered external penetration testing services

External penetration testing challenges the security of all of your perimeter systems, which are  the systems that can be accessed directly from the internet. These systems are often the most easily and frequently attacked since they are easily accessed.

Penti’s autonomous agents and human external penetration testers replicate the actions malicious attackers employ, like chain attacks, OSINT techniques, phishing, exploiting weak passwords and default logins. Penti’s external network pentests will pinpoint your organization’s security weaknesses by combining AI-powered efficiency and human cybersecurity experience.

FAQ

[  01  ]

What is Penti’s external network pentesting?

Penti’s external network pentesting is an AI-powered assessment that evaluates internet-facing infrastructure, or perimeter systems, to identify exposed services, misconfigurations, and exploitable weaknesses.

[  02  ]

How is this different from traditional network vulnerability scans?

Unlike basic scans, Penti validates findings and focuses on attacker-relevant exposures rather than theoretical or low-impact issues.

[  03  ]

What types of assets are tested?

Penti assesses public IP ranges, domains, network services, cloud-hosted systems, and externally accessible infrastructure.

[  04  ]

Does this include exploitation testing?

Yes. Penti safely validates findings to confirm exploitability without disrupting production environments.

[  05  ]

Is this suitable for cloud and hybrid environments?

Absolutely. Penti continuously adapts to dynamic cloud, hybrid, and multi-vendor environments where external exposure frequently changes.

[  06  ]

Does this replace internal pentesting?

No. External network pentesting complements internal assessments by focusing on perimeter and internet-facing risk.

[  07  ]

How does this support compliance requirements?

Findings provide defensible evidence for audits and help demonstrate proactive management of external attack vectors.
