Kerio 4.2 vs. Kerio 2.15

I uninstalled the (bloated) Norton NIS 2005 and replaced it with Kerio 4.2 and AVG AntiVirus 7.0.338, and I am pleased with both the performance and net resource savings (NIS 2005 versus Kerio 4.2 + AVG 7.0). I understand that Kerio 2.15 would result in more resource savings, but I am unclear as to the performance differences between 4.2 and 2.15. Can someone point out the performance capability difference between 4.2 and 2.15?

 

Kerio 2.15 is a very light and simple firewall with no frills, where as Kerio 4.2 contains lots of extras such as web content filtering, IDS etc.

Both are pretty good, but Kerio 4.2 is slower than Kerio 2.15, uses more memory and the GUI (not the firewall) is prone to lock up's when using P2P programs.

 

As Syncman9 points out, I think Kerio 2 might give slightly better performance. Better logging as well, and uses only 5.7mb ram on my 2k machine here.

Also, if you want a good free AV you might try Avast. It is even better than AVG (in my humble opinion of course)...

 

kerio 2.15 is lighter on resources, but Kerio 4.x provides a HIPS (Host Intrusion defense system) i believe (think of it as another layer of defense). However, 4.x is a bit bloated, but not that much. The only problem with kerio 2.15 is that it is not that secure on its own (fails leaktests). If you decide to go with kerio 2.15 (be sure to use the BZ ruleset) try and get proccessguard or a similar program (safe 'n sec comes to mind) to run with it.

Also, try out some more free antiviruses. Avast and Antivir both have better detection rates i believe, and keep bitdefender free as an alternate scanner.

 

Yes... Avast! I think is very compatible w/ Kerio 4.2 and w/ the Avast! Network Shield and WebShield you are a way more safer than AVG.

 

Did anybody test Kerio 2.1.5 with online tests?

I am behing router and would be nice if somebody can test it just to make sure i can install it on friends PC.

 

If you have Kerio with BZ's ruleset, everything will be stealthed*. Online tests i did were from : grc.com, pcflank.com (With Quick Test, even a fully stealthed router will not be stealthed. Pcflank is buggy), Sygate Scan, blackcode.com.

 

I use AVAST with ZA free.

I feel Kerio 2.1.5 is a great application, but I am not sure about AVG, detection is not as good!
