Network Penetration Testing Services
Securexocean's network penetration testing delivers a thorough manual-led assessment of your internal and external network environment, identifying exploitable weaknesses before they are used as breach entry points.
SERVICE INTRODUCTION
Network penetration testing evaluates the security of your IT infrastructure by simulating the tactics, techniques, and procedures used by real threat actors. Unlike vulnerability scanning, it involves active manual exploitation to confirm real-world impact and assess how far an attacker can move through your environment once inside.
Securexocean conducts external assessments targeting internet-facing assets and internal assessments simulating post-breach lateral movement scenarios. All engagements follow PTES, NIST SP 800-115, and CIS Controls frameworks, executed by OSCP and CEH certified practitioners with enterprise network testing experience.
THREAT LANDSCAPE
Enterprise networks carry significantly more attack surface than most organizations actively monitor or test. Exposed management interfaces, unpatched network devices, weak firewall configurations, and flat internal architectures create conditions where a single compromised entry point can lead to full environment takeover.
Attackers targeting network infrastructure combine automated enumeration with manual exploitation of misconfigurations and authentication weaknesses. Internal networks, typically undertested relative to web applications, frequently contain lateral movement paths allowing escalation from a low-privilege user to domain administrator without triggering security alerts.
WHAT WE IDENTIFY AND VALIDATE
Exposed administrative interfaces accessible from external networks
Unpatched operating systems and network devices with known CVEs in production
Default or weak credentials on routers, switches, firewalls, and management consoles
Firewall misconfigurations permitting unauthorized access to internal network segments
Insecure VPN configurations and remote access authentication weaknesses
Active Directory attack paths including Kerberoasting, AS-REP roasting, and pass-the-hash techniques
SMB and RPC vulnerabilities enabling lateral movement across internal segments
Network segmentation failures allowing unauthorized cross-segment access
DNS misconfiguration and zone transfer exposure
Cleartext protocol usage transmitting credentials and sensitive data across the network
IP range definition, assessment type, excluded systems, and testing windows agreed and documented before work begins. NDA executed prior to any information exchange or credential sharing.
Port scanning, service fingerprinting, OS detection, and network topology mapping across the defined scope. External assessments include passive OSINT gathering on exposed infrastructure and internet-facing services.
Automated scanning combined with structured manual analysis identifying misconfigured services, unpatched systems, weak authentication implementations, and exploitable network protocols.
Manual exploitation of confirmed vulnerabilities assessing real breach depth. Post-exploitation activities include privilege escalation, lateral movement across network segments, credential harvesting, and domain enumeration where rules of engagement permit.
Severity-prioritized findings report delivered with full exploitation evidence and network-specific remediation guidance. Walkthrough conducted with your infrastructure and security teams to address questions and guide remediation prioritization.
Verification testing on remediated findings. Closure report issued confirming resolution, formatted for compliance audit evidence and client security assurance documentation.
TOOLS AND TECHNIQUES
Our team uses port scanners, network vulnerability scanners, exploitation frameworks, Active Directory enumeration and attack tooling, credential auditing utilities, packet capture and traffic analysis tools, and post-exploitation frameworks adapted to the target environment. All automated output is manually reviewed and validated. Findings are not included in reports without practitioner confirmation of exploitability and assessed business impact.
Network security posture and priority risk areas for leadership stakeholders.
Technical findings with CVSS v3.1 scores, CVE references, exploitation evidence, and step-by-step reproduction details.
Separate findings sections for external and internal assessments where both are in scope.
Compliance mapping against ISO 27001, PCI DSS, NIST CSF, or RBI Framework where applicable.
Prioritized remediation recommendations specific to your network architecture and device environment.
Post-remediation retest report formatted for audit submission.
COMPLIANCE RELEVANCE
Require documented technical vulnerability management and network security controls. Regular network penetration testing provides direct evidence of both.
Network-level technical safeguard evaluation requirements under the Security Rule are satisfied through documented, regular penetration testing of infrastructure handling ePHI.
Mandate internal and external penetration testing annually and after significant infrastructure changes within cardholder data environments.
Mandates periodic vulnerability assessments and penetration testing for banks, NBFCs, and regulated payment system operators across internal and external network environments.
