Little Snitch is a popular Mac app that detects outbound connections and lets you set up rules to block those connections. Once installed, Little Snitch monitors your internet traffic and every time it detects an outbound connection, for example, Adobe Reader trying to access the internet, it pops up a window and ask you if you want to allow the connection one time, or make a rule to allow Adobe Reader to access the Internet but just not go to adobe.com

In short, Little Snitch is one of the best apps, to keep an eye on your Mac’s Internet connections. But, do we really need an alternative? Well, for starters, it costs you over $40 and upgrades are extra. This alone can be a reason to look for alternatives that cost nothing or at least relatively cheaper than Little Snitch.

Little Snitch Alternatives for Mac

1. Murus Lite

Mac’s own firewall comes with one of the best features available in network firewalls called the PF (packet filter). However, for some users, it may seem a little complex to use and this is where Murus comes in the picture.

Murus brings the PF feature of a firewall in an intuitive, drag & drop based interface that lets you define your own rule set and control the network permissions on your mac. What makes it different from the existing inbuilt firewall? Well, here’s the catch. Common firewalls like Mac’s own PF, restrict and monitor the inbound and outbound network traffic based on attributes like IP address, ports, protocols etc. and by restricting the network functions itself, it affects all the applications. Murus, on the other hand, helps to use PF feature to convert the network firewall into an application firewall wherein you can allow or restrict movement of data packets for each application individually which even helps in restricting spreading of virus, worms or data leak by an application.

Price: Murus comes in three versions: Murus Lite (Free), Murus Basic ($10), and Murus Pro ($17). While Murus lite is the free version of the application, Murus Basic and Murus Pro are the paid versions that come packed with some extra features like logs Visualizer, Vallum, and all companion apps.

2. Radio silence

Radio Silence is yet another application to control your app specific firewall functions. It has one of the simplest interfaces which allows you to keep a tab on applications. Softwares that try to connect with a remote server outside the user’s control are blocked instantly. The Firewall has its eye on the incoming traffic, Radio Silence does the opposite and looks for outgoing traffic too.

Little Snitch vs Radio Silence

Initially, Little Snitch gives you too many notifications about connection, which may feel overwhelming to some users. Although, it goes away after few weeks of usage.

Radio silence, on the other hand, is quite silent in the functionality as it runs in the background. without any active tabs, icon display or pop-ups. Once you block an app with Radio Silence, it stays blocked, there is no notification or pop-ups, ever.

Price: Radio Silence costs around $9 and comes with a testing trial of 30 days. You get your money back if it doesn’t meet your expectations. There’s also a 24-hour free trial available for those who want to test this software’s limits in a single stretch.

3. Private Eye

Private Eye, a real-time network monitoring application that allows monitoring of your live connections made by an application. The app also indicates the presence of an online server where such information is being transmitted.

It displays all attributes of the live connections that the applications in your system have to the web like the time of connection and the IP address of the server connected to.

Although you can filter and view the results by application or by incoming and outgoing traffic, Private Eye doesn’t have the power to alter any of these connections. You get just enough information to know when an app connects to a server without authorization.

Price: Private Eye is a free application.

4. Hands off

Hands off is one of the most trusted applications and alternative to Little Snitch when it comes to network privacy. It is also an all-rounder application that gives protection both as the network firewall and application-specific firewall. It controls both inbound and outbound traffic of an application.

Hands off is a little different from other similar applications. It protects and monitors the disk access, and giving an intuitive and user-friendly interface. This app monitors and blocks access to the files stored in your system from online servers and also from the local applications. It prevents the applications from seeking IP address, accessing disk data, erasing disk data, and even storing cookies. Its disk management is so strict that it even controls the read and write permissions of the disk data files even if the applications have access to the files but the interface and usage come in handy.

Price: Hands Off is otherwise an expensive application ($49) but can be tried and tested for free with limited functionality. The advanced functions of the application are accessible in the paid version. The tutorial file that tags along with the application setup is informative.

5. TCPBlock

TCPBlock is by far the lightest application based firewall available for mac and is absolutely free. It also monitors and protects both inbound and outbound traffic on your mac and can prevent certain applications from opening network connections to unknown servers while you are online.

TCPBlock is implemented as a loadable kernel module which contains all the blocking logic. You can configure it in the System Preferences > TCPBlock preference pane or with the TCPBlock command line utility. All the configuration changes are made in a configuration file on the hard disk of your mac.

Price: Although TCPBlock has discontinued from the market, its previous versions are still available to download for free. It requires only 1.1 MB of your disk space. TCPBlock has the best reviews that an application can get and is still one of the favorites amongst the users. The only catch in using the available version of this application is turning off the SIP (System Integrity Protection). SIP when deactivated, allows third-party applications to run on your mac.

6. Security Growler

Little Snitch is still hands-down the best connection alerting software available for Mac, we suggest to check it out if you want a comprehensive firewall/alerting system, and are willing to pay a few bucks to get it. Security Growler, on the other hand, is centered around monitoring log files for any kind of pattern. It doesn’t just monitors the TCP connection table but also alerts you of Sudo events, Keychain authorization events, and anything else you can think of that’s reported to a log file.

This app is significantly more lightweight than Little Snitch, it comes in at <15MB of RAM used, simply because it aims to solve a simpler problem than Little Snitch. This application is not designed to prevent malicious connections, that’s what firewalls are for, it’s just meant to keep an unobtrusive log, and alert you whenever important security events are happening. The more informed you are, the better you can protect yourself.

Security Growler is a menu bar based application that sends you notifications whenever one of its monitored patterns have a log update. One thing that sets it apart from other applications, Prowl which sends you notifications over your iPhone and iPad.

7. LuLu

LuLu by Objective see is another popular opinion amongst Mac users who wish to keep a check on their system’s network activity. The reason for its popularity is because the software is open source, has no ads whatsoever, and comes with all features.

LuLu aims to block all unauthorized outgoing connections unless you specifically allow them. You can choose to allow local or third-party apps and services from the separated menu available. The app interface is pretty simple yet extensive and its operations are so simple that even a child could use it.

When you first install the app you can choose to allow or disallow Apple programmes and previously installed third-party apps. These settings could be later changed from preferences. Under the ‘rules’ head, you can select the services and apps you wish to block from using network services. The app even has a passive mode where it will allow all new apps and still work in silence for the previously installed apps.

Little Snitch Alternatives for Windows

While there is no true alternative to Little Snitch in Windows, we found two applications that came close.

8. Glasswire

GlassWire is quite a simple app which allows you to monitor changes in the system like microphone, webcam or apps in general. It also comes with a firewall feature just like Little Snitch, however, it isn’t that powerful. For example, Little Snitch can allow or refuse to authorize the specific domain and ports of an application trying to access a server online. GlassWire on the other hand only allows or block all connections an application attempts to initiate. There is no option to make specific rules for an app in Glasswire.

Price: Glasswire follows the freemium model, The free version of Glasswire shows you which program is connected to which IP address. Although, the paid version of Glasswire has “ask to connect” feature, which gives you a pop-up when an app attempts to make a connection.

9. Net Limiter

Compared to Glasswire, Net Limiter is a similar alternative to Little Snitch on Windows. West coast vst free download. Once installed, the app shows you the list of all apps that are making connections to the internet along with their present download and upload speed. You can block network connectivity on individual programs or even restrict how much bandwidth a particular app gets.

Price: Net Limiter is a paid app that cost $29, however it comes with a full 30 days trial.

Little Snitch Alternatives

So, these were some of the free and paid alternatives to Little Snitch. It would be nice if Apple would build such detailed functionality into macOS, but they won’t do it for as simple a reason that it’s too hard to use for a regular mac user. So, you can either spend a few bucks and buy little snitch, or use these alternatives, whatever you use, let us know your thoughts and experiences in the comments. And if you ask my opinion, I’d suggest LuLu because of its intuitive UI and simple controls.

Find out which applications are phoning home or collecting and sending data on your Mac using this handy utility.

Little Snitch Network Monitor is a macOS application that tells you exactly where your data is going to and coming from on the internet. This is a useful tool for rooting out malware on your computer or identifying which applications are hogging all your data. It can also tell you if a website is hijacking your computer to mine cryptocurrency, or otherwise redirecting your data to shady locales.

Little Snitch is easy to use and free to try. In this quick overview, I’ll show you how it works and what it does.

Where is my data going?

The most prominent element of the Little Snitch window is the global map that shows the geographic location of where your data is going to and coming from. In most cases, this won’t mean much—servers are located all over the globe, and just because your computer sends a packet or two to Romania or Switzerland isn’t particularly suspicious.

But if you are noticing strange traffic from an unknown application or a high volume of data being sent to a particular location, then it might be worth looking into. For example, it’s completely normal for Amazon Prime Video to be sending a bunch of data from Seattle since that’s where Amazon’s located. But it’d be more peculiar if your banking or financial application or website were sending data to North Korea at odd hours of the night.

How much data am I sending/receiving?

If it feels like you’re using up more data than you should on a monthly basis, Little Snitch can provide some insight. On the right-hand side is the summary which shows your overall data upload and download numbers. It also shows some statistics that highlight which connections are sending and receiving the most data.

For me, my Backup and Sync from Google is the major data hog. That’s pretty much expected since I use it to sync my photos and videos from iCloud to Google Photos. Red flags in this section would be unfamiliar applications sending lots of data, or applications sending lots of data when you’re not using them. This may be a case of bloatware or it could be malware or a virus. Or, it could be an application that you forgot you had and it’s working as designed.

Which programs are sending and receiving data?

On the left-hand side, you can see an exhaustive list of all connections sending amounts of data large and small. The bulk of the items here will be 100% normal system processes—stuff that Apple uses just to make macOS run smoothly. When you expand these out, you’ll notice they are phoning home to Apple.com, which means you can usually ignore it.

What’s interesting are the annoying third-party programs that occasionally send and receive data in the background. Many applications will have updaters or “helpers” that stay in contact with the developers servers for various reasons, such as checking for application updates. The amount of data is usually small, but if this bothers you, you can block these connections (see below).

Which websites are collecting my data or sending me data?

This one’s a bit eye-opening: when you visit a website, you’re making far more connections than just to the URL in your browser bar. Any given page may have dozens or more elements, scripts, and content from other servers. In some cases, this is perfectly normal. For instance, at groovyPost.com, we host our images on a content delivery network to help balance our server loads and make pages load faster depending on your geographic location.

But when you expand out your Google Chrome item, you’ll see pings from advertisers, analytics services, and other sites as well. Usually, this isn’t a cause for alarm—this is just the nature of the internet. Most websites and publishers are upfront about their use of third-party analytics services and advertising platforms.

Little Snitch Free

That being said, there is potential for abuse. Last year, reports of websites hijacking your CPU to mine for Bitcoin came out. This is called “crypto jacking” and although it’s not really a privacy threat, most consider it unethical to hog your resources so publishers can profit. Little Snitch will tell you if a website is surreptitiously using your web browser to mine cryptocurrency by showing you traffic to domains like Coinhive.com.

Allowing and Denying Connections

The recommended operation mode for Little Snitch is “Silent Mode – Allow Connections.” This lets you watch the traffic going across the transom without actively interfering with any of it. The other options: “Silent Mode – Deny Connections” and “Alert Mode” will quickly grind everyday internet activity to a halt.

The idea is that if you do find a suspicious connection, you can choose to block it on a case by case basis. To do that, simply right-click the connection and choose Deny Connection. Little Snitch will block data from that connection.

Conclusion

Little Snitch is a handy application for monitoring and managing your incoming and outgoing network data on your Mac. The Demo Mode is pretty much unrestricted—pretty much the only limitation is that it will turn itself off every three hours, and you have to restore it. This means that if you suspect that you have malware on your computer or that a website is up to no good, you can use the Demo Mode of Little Snitch to investigate completely for free. If you do want to get a full license, it’ll cost you a little under $50.

Little Snitch does a great job of what it does. What it doesn’t do is monitor traffic on other devices on your network, including internet of things devices, smart home devices, voice-activated assistants, smart TVs, tablets, smartphones, etc. For those devices, you’ll need another solution which we’ll cover in a future post.
