Your external network is the most visible (and vulnerable) part of your infrastructure.
The traditional concept of a "perimeter" has shifted. With the rise of hybrid cloud assets and remote-access gateways, your attack surface is likely larger and more complex than your documentation suggests. For a sophisticated adversary, these aren't just services; they are a series of interconnected entry points.
At Mongoose, we provide more than just a vulnerability list. Our External Network Penetration Testing is a rigorous, manual interrogation of your public-facing footprint. We simulate the persistent techniques of real-world threat actors to identify the architectural flaws and configuration gaps that automated tools overlook.
While automated scanning is a necessary component of security hygiene, it is fundamentally limited in its ability to detect the subtle, logic-based flaws that professional threat actors exploit.
The Intelligence Gap
Automated tools focus on "known-knowns"; common software signatures and unpatched services. They are incapable of:
Logic & Trust Analysis:
Identifying cases where the interaction between two services creates an exposure that doesn't exist when they are viewed in isolation.
Vulnerability Chaining:
Manually pivoting between minor findings to achieve a critical compromise of the infrastructure.
Protocol-Level Interrogation:
Deep, manual probing of custom or complex protocols that standard scanners often misidentify or fail to test thoroughly.
Our testing is built upon the CREST framework, incorporating the technical rigour of NIST SP 800-115 and the Penetration Testing Execution Standard (PTES). This ensures a repeatable, high-quality engagement that meets the most demanding corporate and regulatory standards.
Advanced Reconnaissance & Digital Shadow Mapping
We begin by mapping your organisation's entire digital footprint. This phase identifies the "forgotten" assets that often provide an attacker's first foothold.
Infrastructure OSINT:
Subdomain Discovery:
Credential Intelligence:
Comprehensive Attack Surface Enumeration
We perform a granular interrogation of all identified assets. This is an exhaustive process of identifying every active service and its associated version, configuration, and potential for exploitation.
Infrastructure Fingerprinting:
Edge Service Auditing:
Public-Facing Cloud Assets:
Vulnerability Research & Manual Exploitation
This is the core of our technical work. We don't just report a vulnerability; we research its specific impact within the context of your network.
Vulnerability Chaining:
Custom Exploit Development:
Logic & Configuration Testing:
Post-Exploitation & Risk Analysis
If a vulnerability is discovered, we evaluate its potential for further movement and the broader risk to the organisation.
Pivot Analysis:
Impact Assessment:
We provide the technical depth required by IT teams and the strategic clarity needed by stakeholders.
Zero False Positives:
Every finding is manually verified and documented with clear Proof-of-Concept evidence.
Actionable Remediation:
We don't just list vulnerabilities; we provide the exact technical steps required to secure your infrastructure.
Strategic Insight:
Our reports identify the root causes of exposure, helping you improve your overall security posture rather than just patching symptoms.
