Phishing Simulation Cyber Security Awareness Month
John is professional throughout the process and easy to communicate with, despite the time difference.
He is highly solution-oriented and detail-oriented. John also delivered a well-structured report that provided a clear overview of the findings, methodology, and relevant statistics, which was very valuable.
I appreciate the collaboration and look forward to working with John again in the future.

Bundled Penetration Testing - Web, API and Mobile
Hired for a web application penetration test and was impressed with the quality of work. The findings were technically detailed — not just a list of CVEs, but actual exploitation paths with proper risk context. The final report was well-structured and easy to hand off to the engineering team to act on.
Communication throughout was clear and responsive, and everything was delivered on time without needing to chase. Exactly what you want from a security engagement — no surprises, solid output.
Would hire again for future audits.

Steps for completing your project
After purchasing the project, send requirements so John can start the project.
Delivery time starts when John receives requirements from you.
John works on your project following the steps below.
Revisions may occur after the delivery date.
Planning and Reconnaissance
This stage involves defining the scope and goals of a test, including the systems to be addressed and the testing methods to be used. It also involves gathering intelligence to better understand how a target works and its potential vulnerabilities.
Vulnerability Scan
The next step is to understand how the target system will respond to various intrusion attempts and asses it for known weaknesses.
