Penetration testing -

At Nextdoorsec, we understand that every organization has unique security needs and requirements. That’s why we offer customized security consulting services tailored to meet your organization’s specific needs. We don’t believe in a “one size fits all” approach to security. Sometimes, off-the-shelf security assessments may not be enough to address your organization’s specific vulnerabilities and risks.

Our IT consulting company with experienced security professionals is equipped to provide specialized technology consulting services designed to meet your organization’s unique needs. Whether you need help developing a comprehensive security strategy, conducting a risk assessment, or implementing a specific security solution, we can help.


Our Methodology

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.

"In the world of cybersecurity, we know that Murphy's Law always applies: if anything can go wrong, it will."

🕛 Murphy coined this phrase in the early 1950s. Do you want to risk your company’s reputation with a debilitating hack?
