Sounds like these companies should hire all you guys to do 24/7 monitoring. What are your rates? Do you offer social integration?
This company holds multiple millions of customer dollars, don't be so complacent. I'm fairly sure Havelock can afford to have one guy sit a night shift and alert who ever is needed if something goes wrong, and then post regular updates as things progress. It is actually bewilderingly simple.
>One guy sit on a night shift
I believe data centers already do this free-of-charge (Haha, free, more like 'included in other fees') due to the security of the hardware and data on them. Anyway, it wouldn't be a guard/guy walking around doing it, it'd be a computer program (on a server else-where) checking in every five minutes or so, checking all the common things, site, database, uptime, speed, users, balance, temperatures, ssh sessions, etc...
browsing securities section since few months but not heard of havelock 
Don't browse security section. Ever. I browse the new posts thingy at the top left, click what seems interesting.
