FieldNote: Scanned firewall, found TCP ports open: 25, 80, 443

One time, I had a phone call from the ISP for the company I was working at and they said they did a firewall scan without notifying us. Ok, thanks for that, but next time, be honest and let us know when you are going to perform a penetration test and we’ll be happy to
