External penetration testing
External Penetration Testing is a cybersecurity assessment method designed to identify and exploit vulnerabilities exposed on the internet.
At Patrowl, we conduct automated black-box testing and manual grey-box testing, seamlessly integrated into our SaaS platform.
What is an external penetration testing ?
Imagine your business as a house. You have installed strong locks, an advanced alarm system, and surveillance cameras. But… have you ever tested if your front door is really secure?
An external pentest is like hiring a security expert to try and break in—just like a real attacker would. Their goal? Test your defenses and identify security weaknesses before a real intruder exploits them.
4 steps for an effective external pentest
👉 We handle time-consuming tasks, so you can focus on remediation.
Map your exposed assets: Continuously detect publicly accessible resources and mitigate risks from Shadow IT.
Prioritize vulnerabilities – 0 false positives guaranteed: Every security flaw is human-validated to provide a reliable, actionable report.
Implement a clear action plan: Prioritized based on vulnerability impact, enriched with Indicators of Compromise (IOCs), and transferable in one click to your ITSM.
Automate tracking & retests: Run continuous security monitoring and validate patches automatically.
Certified security experts
Our pentesters hold industry-leading certifications:
SANS GIAC (GPEN, GWAPT, GXPN) – Advanced cybersecurity expert certifications.

Objectives of an external penetration testing – Save Time & Improve Visibility
Optimize your vulnerability management
Stop wasting time on repetitive security tasks. Automate detection & remediation, so you can focus on high-impact security improvements.
Gain full visibility over your attack surface
No more surprises – Continuously monitor exposed assets, Shadow IT risks, and digital threats to stay ahead of attackers.
Receive actionable alerts – without false positives
No more endless reports – Get real-time alerts only for confirmed critical vulnerabilities (CVE, misconfigurations, OWASP flaws).
Verify, fix & retest continuously
Ensure every fix is effective with automated retests and real-time monitoring to detect new threats immediately.
With Patrowl, We Simulate Cyberattacks to:
Identify weaknesses in your digital "house" before hackers do.
Test all possible entry points: doors, windows, or even small gaps in your security perimeter.
Provide a clear action plan to enhance security & prevent intrusions.
Don't let cybercriminals find vulnerabilities before you do!
FAQ
What is the final step in an external safety test?
The remediation phase, during which any vulnerabilities discovered are corrected and verified via a retest.
What are the advantages and disadvantages of internal and external testers?
Internal testers: In-depth knowledge of systems, but potentially biased.
External testers: More realistic perspective, but higher cost.
How many types of penetration test are there?
There are several types of pentest, including internal, external, application, network and social engineering.
What is an external safety audit?
A test that simulates attacks from the Internet to identify and correct vulnerabilities.
How much does an external penetration test cost?
Prices vary according to the complexity of the environment tested and the depth of the analysis. Often, these tests cost several tens of thousands of euros for a single one-off evaluation. Patrowl, on the other hand, offers a sliding scale of charges and continuous protection throughout the year.
