Internal Network Penetration Test
From Foothold to Domain Administrator
Your internal network—LANs, servers, file shares, endpoints, and Active Directory. Subtle misconfigurations, outdated software or weak credentials let cyber criminals or insider threats escalate privileges and move laterally to gain domain‑wide control.
With your authorization, we simulate internal adversary techniques to map attack paths and remediate gaps. Using a mix of automated tooling and hands‑on analysis, we identify critical vulnerabilities, credential weaknesses, Kerberos and ACL abuses, lateral‑movement vectors, and hidden misconfigurations. This is paired with validated, non‑destructive proof‑of‑concepts and prioritized fixes. Ready to secure your internal network? Contact us today for a free consultation.
What is Internal Network Penetration Testing?
Internal Network Penetration Testing simulates an attacker already inside your fortress—pivoting across segments, exploiting weak accounts, escalating access, and compromising the domain. We reveal how far threats can roam. Our hybrid approach ensures a comprehensive, controlled engagement:
- Automated Testing: Aevora Operators will leverage tools such as Nmap, Nessus, Metasploit, and Gowitness for rapid asset discovery and vulnerability scanning. These actions provide quick insight to the internal network. The team will also perform more targeted protocol enumeration with tools like BloodHound, NetExec, and Impacket. Some examples of these tools is gathering data through LDAP queries to find configuration flaws and digging in readable SMB shares to discovered stored sensitive data such as credentials which will be used in lateral movement.
- Manual Testing: We poison network protocols such as LLMNR, NBT-NS, and MDNS to intercept authentication attempts and capture credentials using tools like Responder. Our operators will also manually craft evasion and chaining (e.g., Kerberoasting with custom scripts, pass-the-hash variants)—exposing subtle flaws like misconfigured GPOs, unpatched SMB shares, or custom app backdoors that bots ignore. We also target often-overlooked services such as SCCM (System Center Configuration Manager) and ADCS (Active Directory Certificate Services), leveraging misconfigurations and weak implementations to escalate privileges, move laterally, and gain persistent access within the internal network.
Spotlighted vulnerabilities:
- Privilege Escalation Paths
- Credential Exposure and Dumping
- Default Credentials
- ADCS Vulnerabilities
- Segmentation Failures
- Legacy Protocol Risks (e.g., NTLM relay)
It’s the ultimate internal stress test: We roam free (safely) to cage the real adversaries.
Our Methodology
At Aevora, we don’t do one-size-fits-all. Our penetration testing follows industry-leading frameworks like MITRE ATT&CK and NIST, tailored to your unique environment. Here’s how we deliver results:
- Scoping & Reconnaissance: We collaborate with you to define targets, rules of engagement, and business-critical assets—ensuring zero disruption to your operations. During this time we also discuss specific goals to see if you would like us to attempt to pivot into other network ranges. Aevora operators will also perform passive reconnaissance during scoping to get a general intelligence perspective on the target company and staff.
- Vulnerability Scanning & Enumeration: If you’ve ever wondered if your baseline Nessus scan was enough, the answer is no. We use several different tactics, techniques, and procedures to uncover vulnerabilities at scale. Our operators and their extensive knowledge is where the real value comes in. We scan for vulnerabilities present on in scope hosts and manually probe various protocols such as SMB shares for sensitive data.
- Exploitation & Proof-of-Concept : Rather we start from no access or an assumed breach scenario, we are attempting to exploit vulnerabilities and misconfigurations to traverse the environment and ultimately compromise the domain. All exploitation is conducted in a safe and responsible way to avoid disruption to operations. The team also seeks to find realistic proof of concepts that easily demonstrate impact and include clear steps for reproducing.
- Post-Exploitation Analysis : We don’t stop after a vulnerability is found. Instantly the question, “What is the worst thing that could happen?” gets asked. Aevora operators seek to chain vulnerabilities and move around the environment for additional access.
- Comprehensive Reporting & Remediation Guidance : You’ll receive a detailed report with executive summaries, technical findings, risk ratings (CVSS-scored), and step-by-step fix recommendations. Plus, we offer re-testing at a discount to verify remediations.
All of Aevora’s operators possess the highly coveted OSCP certification and we also have more network tailored certifications such as the OSEP and PNPT. With Aevora you are getting the best and you can have confidence that every test is thorough, confidential, and compliant with standards like PCI-DSS, HIPAA, and GDPR.
Why Choose Aevora for Your Internal Network Pen Test?
In a sea of cybersecurity firms, Aevora stands out because we prioritize your success. Here’s what sets us apart:
- Adaptive and Capable: We have compromised a large number of internal networks. From small companies to massive enterprises—we will find every angle and pry with precision and resilience. Aevora operators are required to remain knowledgeable on the latest security trends, tooling, techniques, and network security concepts.
- Rapid Turnaround: Most engagements are completed in 2-4 weeks. Importantly, we are flexible and are ready to work around the timelines that you require. Engagement length is primarily determined by the size of the internal footprint and Aevora’s testing schedule.
- Transparent Pricing: Starting at $5,000 per week for standard engagements. While scoping, we will analyze the internal network landscape and any specific custom goals established. Custom goals in some scenarios can impact engagement complexity. These details can fluctuate pricing as every internal environment is designed differently and we strive to meet your key goals.
- Ongoing Partnership: Beyond the engagement, you will have access our threat intelligence feeds and quarterly health checks to stay ahead of emerging risks. This is completely free. We want to be your go-to experts year-round. We prioritize your success.
Who Benefits From Our Internal Network Pen Tests?
This service is essential for:
IT and Infrastructure Teams: Gain a clear understanding of your organization’s internal attack surface. Our tests identify misconfigurations, exposed services, and other weaknesses that could be exploited by attackers. The insights we provide help teams prioritize remediation and implement long-term security improvements across network architecture and internal defenses.
Security Teams: Understand the full scope of risks once an adversary gains access to your internal environment. Our assessments reveal hidden vulnerabilities, validate the effectiveness of existing controls, and deliver actionable recommendations to fortify your organization’s security posture against internal threats.
Organizations with Complex Internal Networks: Whether managing on-premises servers, cloud-hybrid environments, or remote access systems, our tests ensure these assets don’t become weak points. Regular internal penetration testing is vital to secure critical infrastructure, especially as organizations scale and adopt new technologies.
Heavily Regulated Industries: Meet strict compliance requirements such as PCI-DSS, HIPAA, and GDPR. Our penetration tests provide the necessary evidence and risk insights to satisfy auditors and regulators. If you have specific compliance requirements, be sure to let us know during scoping.
Companies Preparing for Funding, Acquisition, or Compliance Audits: Demonstrate a mature security posture to investors, acquirers, or auditors. A clean, professional penetration test report shows due diligence and builds confidence in your internal network security.
Businesses of All Sizes: From startups building their first internal networks to enterprises managing global infrastructure, every organization benefits from securing its internal assets. Automated scans miss critical context—our manual testing provides the depth needed to protect your internal network, data, and reputation.
