External Penetration Testing
At Nextdoorsec, we take external penetration testing to the next level. We use simulated hacking attacks to test the effectiveness of your IT security defenses against real-world threats. Our experienced engineers perform open-source intelligence gathering to find sensitive information that can be used to exploit potential vulnerabilities in your external network. We also conduct thorough scanning and enumeration to identify possible weaknesses in your systems and assess the extent of the damage a real attacker could cause. With our external penetration testing, you can rest assured that your organization is prepared to defend against external threats.
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.
