Do you perform both vulnerability assessment and penetration testing?

Yes. The engagement includes identifying weaknesses and validating whether they can be exploited in practice.

What level of access is required for testing?

Testing is typically performed with assumed or provided access, such as a standard user or domain user account.

What is included in the testing scope?

Scope includes internal systems, services, Active Directory, and network segments. Final scope is defined during engagement setup.

Do you test Active Directory environments?

Yes. Testing includes enumeration, privilege escalation paths, and misconfiguration analysis.

Will testing impact internal systems?

Testing is conducted in a controlled manner to minimize disruption, depending on the agreed scope.

Do you test lateral movement and privilege escalation?

Yes. Testing focuses on how access can be expanded across systems and identities.

Do you provide retesting after fixes are implemented?

Yes. Retesting is included to verify remediation.

What will be delivered at the end of the engagement?

A report with validated findings, including reproduction steps, impact, remediation guidance, and mappings to CWE, CVSS, OWASP, and CVE where applicable.

INTERNAL / NET

InternalNetworkPenetrationTesting

Internal Network Vulnerability Assessment and Penetration Testing (VAPT) to identify and validate real security risks across internal systems, identities, and privilege escalation paths.

IDENTITY // LATERAL // PRIVESC // DETECT // IDENTITY // LATERAL // PRIVESC // DETECT

Service Overview

Internal Network Penetration Testing focuses on identifying weaknesses within enterprise environments from the perspective of an internal or authenticated attacker.

The assessment evaluates how access can be expanded after initial entry, how credentials can be abused, and how privileges can be escalated across systems and identity infrastructures. This includes testing how internal services are exposed, how trust relationships are configured, and how systems can be accessed or compromised through lateral movement.

The objective is to determine how an attacker can move within the environment, what systems can be reached, and how sensitive data or domain-level control can be obtained. Findings are validated to ensure they represent real and actionable risk.

Attack Path Validation

From initial access to domain compromise

Weaknesses are assessed across systems, services, and identity controls, focusing on how issues such as credential exposure, misconfigurations, or weak permissions can be combined to escalate privileges, move laterally, and compromise critical systems.

Benefits

Clear visibility into internal risk

Identifies how internal systems and identities can be abused after initial access.

Focus on privilege escalation and lateral movement

Highlights paths that lead to high-impact compromise.

Confirmed exploitability of attack paths

Validates whether access can be expanded across the environment.

Accurate understanding of internal security posture

Reflects how the environment behaves under real attack conditions.

Why Choose VulnXperts

What We Test

A structured review of how internal systems, services, and identities can be accessed and abused to expand access, escalate privileges, and reach critical assets.

How we approach testing

Testing begins with limited or assumed access, followed by systematic enumeration, exploitation, and validation of how access can be expanded across systems and identity boundaries.

Automated vulnerability discovery and baseline risk assessment

Manual penetration testing for validation, exploitation, and attack path confirmation

Internal network reconnaissance and service enumeration (TCP/UDP scanning, fingerprinting)

Network topology, segmentation, and trust boundary mapping

Attack surface identification across internal services and management interfaces

Credential exposure and abuse (weak passwords, reuse, spraying, NTLM relay)

Authentication and authorization testing across internal systems

Validation of outdated, unpatched, or unsupported systems and software (CVE-based, EOL exposure)

Local and domain-level privilege escalation (Windows/Linux)

Credential extraction (LSASS, SAM, NTDS, cached credentials)

Active Directory enumeration (users, groups, permissions, trusts)

Active Directory attack path analysis (ACL abuse, privilege escalation paths)

Kerberos abuse (Kerberoasting, AS-REP roasting, ticket misuse)

Delegation abuse (unconstrained, constrained, RBCD)

AD CS misconfiguration testing (certificate abuse, escalation scenarios)

GPO misconfiguration and abuse testing

Lateral movement using compromised credentials or sessions

Internal pivoting (port forwarding, SOCKS proxying, cross-segment access)

Network segmentation bypass testing

Name resolution poisoning (LLMNR, NBT-NS, mDNS, WPAD)

Exploitation of internal services (SMB, LDAP, RDP, WinRM, SSH, HTTP/S, databases)

Service-level vulnerabilities (command execution, misconfigurations)

Injection and input handling testing where applicable

File-based vulnerabilities (LFI, RFI, path traversal on internal apps)

Sensitive data exposure (file shares, backups, configs, logs)

Persistence mechanisms (scheduled tasks, services, registry, GPO-based persistence)
