Ask HN: Review my idea and free web app (for site monitoring)
I submitted a similar post a while ago, but it seems that my msg was lost (yes, I shouldn't have set a URL).
Anyway, what we developed is more than just a normal site monitoring that checks if a site is up or not, but a new concept of Network-based integrity monitoring (NBIM).
The idea is to monitor the integrity of network/Internet assets, similarly to what we are used with file-based integrity. In a nutshell, it will verify that important parts of your Internet presence have not being altered.
Our beta product, NBIM, offers this functionality to detect changes (malicious or not) on web pages, http headers, whois database, DNS, host, HTTPS pages, and SSL certificates (with more to come). If anything ever changes, you get an email alert (or tweet to be cool) almost in real time showing a diff between the old and new snapshot.

Comments about the idea, page design, implementation, concept, etc are welcome!
Thanks!
