Network Penetration Testing Service Internal and External
I provide comprehensive network penetration testing services to evaluate how resilient your internal and external infrastructure is against real world attacks.
This service simulates how an actual attacker would attempt to gain access move laterally escalate privileges and compromise critical systems within your environment. The goal is not just to identify weaknesses but to understand real impact and attack paths.
External Network Penetration Testing
External testing focuses on what an attacker can reach from the internet.
What I Test
Public facing IP ranges and network services
Open ports exposed services and misconfigurations
Firewall and perimeter control effectiveness
VPN gateways remote access services and authentication mechanisms
Outdated software and exploitable vulnerabilities
Objective
Determine whether an external attacker can gain an initial foothold into your network and identify paths to deeper compromise.
Internal Network Penetration Testing
Internal testing assumes the attacker already has limited access such as a compromised user device or internal network presence.
What I Test
Internal network segmentation and trust boundaries
Privilege escalation opportunities
Lateral movement across systems
Credential exposure and reuse
Critical server and service access
Objective
Evaluate how far an attacker can move inside the network and what damage they can realistically cause.
Methodology
Threat modeling based on your network architecture and business context
Manual testing supported by controlled tooling
Chaining of misconfigurations vulnerabilities and trust relationships
Careful validation to avoid operational disruption
Focus on realistic attack scenarios rather than isolated issues
Deliverables
Executive ready report with clear risk assessment
Technical findings with exploitation evidence
Attack path diagrams showing how compromises chain together
Actionable remediation guidance prioritized by impact
Optional retesting to validate fixes
Who This Is For
Organizations preparing for audits or compliance reviews
Enterprises validating network hardening efforts
Security teams seeking real world attack simulation
Businesses wanting assurance beyond vulnerability scans
Value You Get
Clear visibility into real network risk
Understanding of how attackers move inside your environment
Prioritized fixes that actually reduce exposure
Improved confidence in your defensive controls
If your network supports business critical systems and sensitive data
I help you understand how it can be attacked and how to stop it before it matters.
