I worked for a ISP. A cable company. We were getting our local offair channels from a site that was in easy reception of them. They had a large amount of bandwidth and did the same thing for dish and direct tv. The man who ran network side had a stroke and died. The hack that ran the broadcast side of their main business took over. Next thing I know I’m having all kinds of problems with our multicast tunnel. I port scanned the IP range and discover they have opened the whole thing up. We had a conference call where I detailed my concerns. Later that day the hack called my boss with his boss on the line and we had another meeting where I told them that they were exposed with default passwords and it could be a real problem.
After I was given verbal permission to demonstrate my concerns with some limitations I took over all default password equipment and sent a large amount short stories to their printers. I ended it with the story superiority by Author C. Clark. Some back and forth a day later and they needed a new sysadmin.
For a small to medium sized business pfsense is the only solution that makes sense. The only requirement is that you have a actual sysadmin on staff and not a vendor jockey.
