Trusted Internal Penetration Testing Services
During an internal penetration test, a Nextdoorsec engineer simulates an attack from inside the network just like blind penetration testing, identifying potential host vulnerabilities through network scanning. Our team then executes both common and advanced internal network attacks such as LLMNR/NBT-NS poisoning and man-in-the-middle attacks, token impersonation, kerberoasting, pass-the-hash, golden ticket, and more. Our goal is to gain access to hosts through lateral movement, compromise domain user and admin accounts, and exfiltrate sensitive data, ultimately providing a comprehensive evaluation of your organization’s internal security posture.

At Nextdoorsec, we follow industry-standard methodologies such as NIST SP 800-115 Technical Guide to Information Security Testing and Assessment and OWASP Testing Guide (v4) to provide offensive cybersecurity services to our clients. In addition to these, we also use customized testing frameworks to ensure that our testing covers all aspects of your IT infrastructure and helps you identify and remediate vulnerabilities before attackers can exploit them.
At Nextdoorsec, we start each project by gathering customer goals and obtaining rules of engagement. This ensures that we fully understand our client’s needs and requirements, allowing us to tailor our offensive cybersecurity services to best meet their needs.
We kick off our offensive cybersecurity services by performing a thorough scanning and enumeration process. This helps us identify any potential vulnerabilities, weak spots, and possible exploits that can compromise your organization’s security.
Nextdoorsec will exploit possible vulnerabilities to confirm them. This helps us assess each vulnerability’s effect on your IT infrastructure. Once successful access has been obtained, additional discovery will be conducted to explore the extent of the potential risks.
Nextdoorsec carefully documents all identified vulnerabilities, successful and unsuccessful exploitation attempts, and overall company strengths and weaknesses to provide comprehensive and actionable reports to our clients.
