Network Penetration Testing Services
Perimeter and internal network audits targeting unpatched software vulnerabilities, weak VPN controls, and exposed server ports.
Comprehensive Network Assessment Modules
1. External Perimeter Port & Service Audits
Exhaustive TCP/UDP port enumeration and banner-grabbing to detect exposed databases (Postgres, MongoDB, Redis, Elasticsearch), management interfaces (SSH, RDP), and legacy unauthenticated services.
2. VPN & Corporate Remote Access Testing
Evaluating OpenVPN, IPsec, WireGuard, and enterprise gateways for split-tunneling leaks, outdated firmware CVEs, brute-force vulnerabilities, and multi-factor authentication (MFA) bypasses.
3. Internal Network Segmentation & Lateral Movement
Simulating compromised workstation scenarios to assess VLAN segmentation, Active Directory Kerberoasting, LLMNR/NBT-NS spoofing, and privilege escalation pathways.
4. Firewall & Zero-Trust Architecture Review
Auditing cloud security groups, web application firewalls (WAF), and ingress routing rules to eliminate overly permissive CIDR blocks (0.0.0.0/0) and unsegmented staging subnets.
Network Pentesting Methodology & Executive Deliverables
Our certified penetration testers follow NIST SP 800-115 and PTES standards, combining automated discovery with manual protocol verification. We provide actionable remediation guides, firewall rule modifications, and an executive attestation letter for compliance auditors.
Frequently Asked Network Pentesting Questions
What is the difference between external and internal network penetration testing?
External testing evaluates internet-facing assets (firewalls, routers, VPN gateways, public DNS, exposed cloud endpoints) from an outsider's perspective. Internal testing simulates an attacker who has already breached the perimeter or an insider threat, testing segmentation, Active Directory, and lateral movement.
Will network security testing cause disruptions or bandwidth throttling?
No. We calibrate our network port enumeration rates and packet transmission thresholds to avoid overwhelming firewalls, IDS/IPS sensors, or application servers. Testing can also be scheduled during off-peak maintenance windows.
Do you audit Active Directory domains and Kerberos configurations?
Yes. Our internal network assessments include Kerberoasting, AS-REP roasting, BloodHound relationship mapping, ACL misconfiguration analysis, and privilege escalation vectors across hybrid Entra ID / Active Directory domains.
Is your pentest report accepted by SOC 2, ISO 27001, and enterprise vendor auditors?
Yes. Our deliverables include an executive summary, CVSS v3.1 technical vulnerability breakdown, evidence screenshots, remediation steps, and an official Third-Party Attestation Letter suitable for compliance auditors.
