Understand Your Exposure: What’s Visible and Vulnerable to the Outside World
External infrastructure penetration test provides a crucial, real-world assessment of your organisation's internet-facing assets. At CypherLeap, we simulate attacks from an external threat actor's perspective, without any prior internal knowledge of your systems.
This assessment aims to uncover what external threat actors could achieve on your internet-facing assets, identifying exploitable vulnerabilities in your firewalls, web servers, email gateways, and other public-facing infrastructure before malicious actors can find and exploit them. It's about revealing your external attack surface, helping you proactively strengthen your perimeter defences against genuine cyber threats.
Our Offensive Security Services team executes test cases outlined by the Penetration Testing Execution Standard (PTES) and/or the Open-Source Security Testing Methodology Manual (OSSTMM).
Realistic Adversary Simulation to Measure True External Exposure
External Infrastructure assessments are mostly conducted using an Un-authenticated, Black-Box approach to mimic an external adversary.
- Black-Box Assessment
- Un-Authenticated
Assessment in which the testing team will have no prior knowledge about the targeted environment, systems and endpoints.
The unauthenticated testing approach provides your business with visibility into what a potential threat actor could access and/or compromise with only access to the agreed testing scope.

Frequently Asked Questions
Do you test cloud-hosted infrastructure like AWS, Azure, or GCP?
Yes. We perform thorough assessments on cloud-hosted services, including public IPs, virtual machines, web apps, APIs, and cloud security configurations always within the approved scope.
Will your test disrupt our live services?
No. All testing is designed to avoid service interruptions. We coordinate closely with your team, ensuring testing is safe, controlled, and compliant with operational constraints.
How often should external penetration testing be performed?
At minimum, annually or after significant infrastructure changes. More frequent testing is recommended for high-risk industries or critical applications exposed to the internet.
