I love both your Network Scanner and Switch Port Mapper - Great job on both.
I am sending this message just to make a suggestion. It would be great to have the option to pull SSL certificates as part of netscan. Now that certs have to be renewed every year, having a column that said the DNS name of the cert on anything running on 443 would really help when trying to make sure you didn't miss renewing anything. Throw the expiration date in as well and it would be fantastic.
Either way awesome software and great job - Thanks.
