Identify Network Weaknesses Before Attackers Breach Your Perimeter
Enterprise networks remain a primary target for cyber attackers seeking unauthorized access, lateral movement, and full environment compromise. Whether attacks originate externally from the internet or internally from compromised user accounts, insecure network configurations and unpatched systems create high-risk entry points.
BugFoe, an ISO 27001:2022 certified Managed Security Service Provider (MSSP), delivers comprehensive Internal and External Network Penetration Testing services designed to identify exploitable vulnerabilities, validate security controls, and assess real-world attack paths across enterprise infrastructure.
Our assessments simulate sophisticated attacker behavior to uncover weaknesses that traditional vulnerability scans fail to identify.
What Is Network Penetration Testing?
Network Penetration Testing is a controlled security assessment that evaluates the security posture of an organization’s internal and external network infrastructure by simulating real-world cyberattacks. The goal is to identify vulnerabilities, misconfigurations, and trust relationships that attackers could exploit to gain unauthorized access.
BugFoe’s network testing covers:
- External-facing infrastructure
- Internal enterprise networks
- Servers, endpoints, and network devices
- Active Directory and identity services
- Segmentation and trust boundaries
Why Network Penetration Testing Is Critical
Attackers rarely rely on a single vulnerability. Instead, they chain multiple weaknesses together to move laterally and escalate privileges. Network penetration testing reveals how individual issues combine into high-impact attack paths.
Common Network Risks Identified
- Unpatched systems and exposed services
- Weak authentication mechanisms
- Insecure network segmentation
- Misconfigured firewalls and ACLs
- Weak Active Directory controls
- Privilege escalation paths
- Lateral movement opportunities
- Insecure legacy protocols
Strengthen Your Network Defenses Today
Enterprise networks are complex and constantly evolving. Regular penetration testing is essential to identify weaknesses before attackers exploit them.
BugFoe Network Penetration Testing Methodology
Our methodology aligns with PTES, NIST, and MITRE ATT&CK, while incorporating real-world attacker tradecraft.
Scope Definition and Attack Surface Mapping
We begin by defining the testing scope and understanding network architecture.
Activities include:
- IP range and asset identification
- Network topology analysis
- External exposure assessment
- Identification of critical systems and data
This ensures precise and risk-focused testing.
External Network Penetration Testing
We simulate attacks from an external threat actor with no prior access.
Testing includes:
- Perimeter scanning and enumeration
- Service and version identification
- Exploitation of internet-facing vulnerabilities
- Firewall and intrusion detection bypass attempts
- Credential exposure testing
This phase evaluates your first line of defense.
Internal Network Penetration Testing
We simulate attacks originating from inside the network, such as compromised endpoints or malicious insiders
Testing includes:
- Network enumeration and discovery
- Credential harvesting and abuse
- Active Directory attacks
- Lateral movement techniques
- Privilege escalation attempts
Internal testing reveals the potential blast radius of a breach.
Active Directory and Identity Attack Simulation
Active Directory is often the ultimate target in enterprise attacks.
We test for:
- Weak password policies
- Kerberos and NTLM attacks
- Misconfigured group policies
- Delegation and trust abuses
- Domain privilege escalation
Segmentation and Trust Boundary Assessment
We evaluate network segmentation effectiveness.
Testing includes:
- VLAN and subnet isolation validation
- Firewall rule testing
- Access control enforcement
- Cross-zone attack attempts
Poor segmentation significantly increases breach impact.
Risk-Based Reporting and Attack Path Analysis
Each finding is analyzed to identify:
- Attack paths
- Business impact
- Likelihood of exploitation
- Risk severity
This enables strategic remediation planning.

Find The Right Answers To Your Questions
Our FAQs section provides clear answers to common concerns about.
What is the difference between internal and external testing?
External testing simulates internet-based attacks, while internal testing simulates attacks from within the network.
Do you test Active Directory environments?
Yes. Active Directory testing is a core component.
Will testing disrupt operations?
No. Testing is controlled to avoid business disruption.
Can testing be performed remotely?
Yes. Both internal and external testing can be conducted remotely or on-site.
