I'm sorry, but unfortunately still do not know why it has 20,000 fewer rules in its database, compared with a publicly available database of Snort, which is used for IPS Astaro. Does this mean that we have less secure network with Astaro 8200?
Many of the rules in the community database version of snort have not been rigorously tested and can frequently cause false positives. As well, there are many rules which don't work or have long ago been superseded. Astaro is a commercial product, so must be more diligent about the rule sets that it uses, so as not to cause issues for its' paying business customers.
This does not make it less secure, but more tuned for efficiency and usability.
