Hi

Two advises, get this report offline a.s.a.p. because your website is now known and prown to attacks. (happy to see it appears not to be vulnerable to SQLi attacks)

You purchase Acunetix without knowing how to fix XSS? Please explain... are you learning pentesting and have big budgets?

Next to understand XSS scripting. It is about executing a script from user input, this is not good but can be easily avoided if you install MS URLSCAN.
I see you are using IIS 7 so this tool will work perfectly.

Please know Acunetix uses pretty 'safe' Cross Side (java) Scripts to test your website, if a 'blackhat' visitor catches this report before you fix the issues he can create BIG DAMAGE to your website. (deface it, upload other content etc etc)

Simplest advise i can give you is install URLSCAN from Microsoft like advised.

If you really want to show this report to more people please take it offsite and anonymise it.

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

Yes of course.

First URLSCAN is a tool made by Microsoft which prevents users to input dangerous characters like < % ' etc. This is the most easiest way to protect against XSS.

If not desired (which i can understand if e.g. you only have one production server so you cannot test it) you should filter your scripts.
Acunetix has this page for you or your developers to read. LINK

Last thing i could recommend it installing ACUSENSOR in your project. This gives you an even better pentest results and will advise on how to improve your source code. For the latter you need .NET3.5 installed on the IIS server.

i had a quick look at your website and found some very dangerous flaws which should be fixed right away.
