Little Snitch is probably the best investment in software I've done in the past few years. Although I've tried and removed many other security programs in the past, Little Snitch is going to stay.

Installation is a piece of cake and the information provided by the program is excellent for beginners and pro's alike. Once you get over the annoying start by answering to each and ever request to access the internet, the program quietly monitors your machine. Today I trapped the first real Trojan that tried to access my machine via the JavaApplicationStub. Via the browser, the Trojan was accessing a server to which I was logged on! I was able to kill it with a single click.

Little Snitch is well worth the money and does what it promises. Furthermore, it has a VERY slick and smooth user interface and is easy to understand. If you are serious about security (which you should be), Little Snitch is a must!

Etwas mehr Übersicht welches Programm was wo hin senden will.
Zu kontrollieren was man senden und nicht senden möchte ist eigentlicher Standard dem jeden etwas mehr Kontrolle seiner Daten gewährt.
Für meine begriffe sollte dieses Programm Standard auf jeden Computer sein !!!

Have been using this app for years and I don't think I've ever had an issue with it. There is a learning curve but when you consider what it does that should be somewhat expected. I love having control over my incoming and outgoing network connections. The internet can be a dangerous place and for me a properly configured Little Snitch is a must have on any Mac I use.

I'm using the latest 3.3. Anyone know of a way to TEMPORARILY (as in like a toggle) block all connections, period, overriding all rules? I know selecting Stop Network Filter will allow everything, I want the opposite, block everything. Just temporarily, then toggle back to normal with rules in effect again.

There are hints on the web about creating a separate profile, in that profile, there would be just one rule, block everything. Then switch back and forth between profiles. This seems 'hacky' and I can do it, just wondering if I missed something in the manual about some flip switch or toggle.

Another way I've done it is to go to OS X System Preferences and switch to a network profile that has no enabled network adapters, but this isn't quite what I want. For testing purposes, I want apps to see that there is a connection, but not be able to get access.

So decided to try creating a new Profile, first time I've played with this feature. Apparently by default all my current rules (some 150+) are enabled by default for ALL profiles, so when I created a new profile called 'Block All', it inherited all my rules.

So, then I thought, okay, I just have to delete them all in the Block All profile. Well deleting a rule that is enabled in all profiles, deletes it in ALL profiles. Unchecking the 'On" box in any profile, unchecks the rule in ALL profiles.

So after about an hour of playing around, I can NOT figure out how to move all my rules into a profile called Default, and have none of them 'Enabled in all profiles'. Whatever action I take on any rule, gets applied in all profiles. What I was trying for is to be able to flip back and forth between a profile called 'Default', which would contain what used to be all my rules listed under "Enabled in all profiles", and a profile called "Block All", which would have two rules for 'Any Process', Deny All Incoming and Deny All Outgoing.

after an email conversation back and forth with ObjectDev support, it appears the only method at this time to temporarily block all traffic is to create a new profile. The new profile will unfortunately inherent all your rules from the "Enabled in all profiles" group, but the saving grace is that rule precedence will force all of those rules to be overriden by two rules that blocks in and out traffic for all processes/apps.

It isn't very clean, and you have to understand rule precedence, but it works. I DO want to say support was extremely courteous and responsive, my experience with support in this situation bought them a good deal of customer loyalty from me.

I suggested to them in future releases the following:
1) a system wide 'kill switch' toggle that will immediately block all in and out traffic overriding all rules
2) a rethinking of the 'Profiles' feature, especially how old rules get automatically enabled in all profiles. There should be a way to start a new profile with a completely blank slate.
3) tie profiles to the user login, and allow password protection, so one could for example ensure that your children operate with one profile, and the parent with another. I realize this is borderline beginning to cross over into a security / firewall program territory, but in many ways LS is already kind of a front end to managing your firewall anyways, with far greater control and ease than what you can do in System Prefs/Firewall
4) separate from the profiles feature, optional user password protection to prevent LS changes would be nice.

I think ObjectDev sees their market right now as primarily the individual techie person with a fairly high level of system knowledge and experience working on a single system or systems only the individual uses. And that is probably true and fine. I think there is a market too for network administrators or heads of family who have to manage systems with multiple users. The Profiles feature is a good start, I look forward to further improvements.

I think that the network monitor need more performance improvements, especially when you do a mouse over, it doesn't appear in a fluid way, I'm still testing but that's my first impression of the preview 3.

I've had no KP's with 2.4.4 on Lion. There is one glitch in the configuration settings though -- you can't open the "Choose System Process" dialog when adding a new rule.

In french, sorry.

J'aime beaucoup Little Snitch mais il y a un problème avec cette version 2.3.3.

Le chargement de certains flux RSS dans Safari est ralenti. Constatation identique sur certains sites d'actualité (Le Monde, Liberation, etc...) ou simplement sur MacUpdate.

La roue crantée dans la barre d'adresse n'arrête pas de tourner.

J'ai aussi constaté un ralentissement dans le chargement de Safari Webpage Preview Fetcher.

Revenu à la version 2.3.2 tout est entré dans l'ordre.

Vous avez peut-être bloqué un plugin important sans vous en apercevoir? J'avais bloqué flash sans faire exprès, et il m'a fallu pas mal de temps pour m'en rendre compte. Je vous conseille de passer vos Rules au peigne fin pour voir si le programme ne fait pas d'excès de zèle.

Is anyone having the problem with Little Snitch that it keeps allowing callouts from apps and/or system processes that had a rule to DENY callouts? I know LS inside and out and am absolutely positive that it's setup correctly, so it's definitely not human error. Nevertheless, it keeps letting the system process mach_kernal (which is known to LS as Mac OS X Kernal) callout even though just this morning I set up a rule to block it, then checked again tonight with the same result.

D'oh, there it goes again!

I'd like to know whether others are having this problem, or just me.

Thanks.
