Hi, i'll not only provide you list of open ports and DNS entries but i can also provide you with the software/Application running on these ports in most cases.

I have previous experience doing this type of work. After verifying the port is open, I will also do a banner grab so that you can understand what service is running on that port. This is something some of the other bidders may not know. Services are not required to use specific port numbers so while a server might have port 80 open, it might not actually be a web server running on that port. A banner grab will attempt to identify that service which I will also include. I will provide you a formal report including statistics from my findings. I ask for 1 day to perform the scan and another day to document and provide a professional report. Thanks, JITNC1
