Infrastructure
Penetration Testing

Internal and external network assessments that enumerate real attack paths, exploit unpatched systems, and demonstrate the true impact of infrastructure vulnerabilities.

Overview

Your network perimeter and internal infrastructure are under constant pressure from automated scanners, vulnerability brokers, and skilled adversaries. Our infrastructure penetration testing engagements go further — operating with genuine attacker tradecraft to identify, chain, and exploit vulnerabilities that lead to meaningful compromise.

External Infrastructure Assessment

We simulate a threat actor with no prior access and no insider knowledge — starting from nothing but your organisation's public footprint. We enumerate exposed services, identify misconfigurations and unpatched vulnerabilities, and attempt to gain an initial foothold. Where access is achieved, we demonstrate the realistic impact: credential exposure, service compromise, or a pivot point into your internal network.

Internal Infrastructure Assessment

We simulate an attacker who has already crossed the perimeter — whether through phishing, a compromised credential, or a malicious insider. Starting from a position of limited internal access, we map your Active Directory environment, identify privilege escalation paths, and attempt to achieve domain or enterprise-wide compromise. This assessment answers the question most organisations struggle with: if an attacker gets in, how far can they go?

Combined Engagement

Both assessments can be run as a single continuous engagement, demonstrating a full kill chain from initial external access through to internal domain compromise — the closest simulation of a real-world targeted attack. Every finding is manually validated. No raw scanner output, no false positives handed to your team to triage. Our operators follow the same methodology as real threat actors: we don't stop at identifying a vulnerability, we follow the path to its worst-case business impact.

Testing Methodology
01

External Reconnaissance

OSINT gathering, DNS enumeration, certificate transparency analysis, ASN mapping, and passive service fingerprinting to understand your externally visible attack surface before any active scanning begins.

02

Network Scanning & Service Enumeration

Comprehensive port scanning and service version detection across all in-scope IP ranges. Banner grabbing, protocol analysis, and identification of running services cross-referenced against known vulnerability databases.

03

Vulnerability Identification & Validation

Manual validation of all identified vulnerabilities to eliminate false positives. We cross-reference CVE databases, vendor advisories, and our own research to confirm exploitability in your specific environment and configuration.

04

Controlled Exploitation

Safe exploitation of confirmed vulnerabilities to demonstrate real-world impact. Safe exploitation parameters are agreed during scoping to protect production systems while still proving meaningful access.

05

Post-Exploitation & Lateral Movement

From initial foothold, we attempt credential harvesting, lateral movement, persistence, and privilege escalation — demonstrating how far an attacker can progress from a single compromised host.

06

Reporting & Debrief

Full technical report with attack narrative, evidence, risk ratings, and remediation recommendations. Executive summary and debrief session with your technical and leadership teams. Retest included as standard.

What Makes Levantis Different

We approach every infrastructure engagement with an attacker mindset — not as a compliance exercise. Our operators exploit what they find and chain vulnerabilities together, exactly as a real adversary would. Every critical finding is raised immediately, not held for the final report.

Reports are written by the operator who conducted the testing. You receive clear, evidence-backed findings with direct remediation guidance — and we remain available throughout your remediation effort.
