Well,ZA does have SPI. On this website there are the feature lists. http://www.zonealarm.com/store/support/zaas/generalFAQs.jsp#3 I honestly doubt that Checkpoint wouldn't put full SPI inside ZA since they bought them. Regarding awards:I'm not sure if they were established themselves,but if you look in every review of them,you'll see that ZA blocks almost everything to get installed on your computer-and I don't believe they fake test results. It seems to me that other security testers who don't like ZA hate ZA and they want shutdown ZA's production... And again if you don' believe that take me as an user of ZA Pro and Nod32 antivirus(with Outpost Pro and Nod32 on the second computer and Jetico2 on the 3rd computer). Since I got ZA Pro I was testing its inbound protection (of course, you need to configure it to get maximum protection) against malware-loading websites. I don't want to name them,because i believe it's forbidden to post such links, however if you don't have adequate protection you will be infected. The main problem with these websites is that as long as you're connected they'll try to install malware... From my personal experience,I've never been infected while using ZA Pro (at maximum protection). The reason why I know this is because I had for extra case Spyware Doctor (but I deactivated its real-time protection while using ZA Pro's real-time spyware protection), Lavasoft Ad-Aware, Super-Antispyware and a few other antiviruses to check if there are any malware samples inside my computer,I found nothing,ZA found nothing, and my computer has never been compromised/zombified. So these awards mean something,it's not just awarding with no reason. You can believe or you don't have to believe me,it's your choice,but with ZA Pro I was the most secure (even more secure than with Outpost Pro). That's why, despite all marketing and establishment,yes ZA's techies are doing their job excellent. If ZA is bad I would already have malware samples installed on my computer, but I don't have them-any of them. The only problem is that right now ZA's techies are having problems with Vista compatibility. Cheers!
