When an app tries to connect to the internet, you get a notification. But you can also set rules for inbound activity too. Just like Little Snitch and Lulu, Vallum intercepts outgoing connections from your Mac’s various apps.

Pros: Does a good job and is completely freeĬons: Not much control over temporary rule Block stops all traffic, while passive applies only existing rules. It can run in a few different modes: Passive, Block and no icon. Lulu is only meant to block outgoing connections, but you could pair it with the macOS firewall if you’re worried about incoming connections. Make no mistake: Lulu doesn’t offer the same level of control as in Little Snitch. You also get a network monitor, so you can keep an eye on what Mac apps are doing what in real-time As well as changing the block or allow status, you can delete rules altogether or add domains or ports to the rules. Lulu can either apply the rules based on processes or on the domain level.Īfter that, you can head into the app to edit your rules. You can then block or allow the connection, either temporarily or permanently. When it’s enabled, you receive notifications whenever an app tries to connect to the internet.

Lulu works in pretty much the same way as Little Snitch. Pros: Lots of options that put you in controlĬons: A bit pricey and maybe too advanced for beginners It’s a little expensive but worth it if you need total control. Although the focus is very much on outgoing connections, Little Snitch can also control incoming connections to a lesser degree. And you want to avoid notifications, you can run Little Snitch in Silent Mode, which will allow or deny all connections. Using Little Snitch’s built-in Network Monitor, you can view and analyze any processes that are showing network activity. So you could allow an app to connect to certain servers but not others. These rules are based not only on the app that’s trying to connect to the internet but also the domain it’s trying to connect to. You can then edit these rules in the Little Snitch client. When you choose to block or allow an app access to the internet, Little Snitch creates a rule. You can also set it for a certain period of time or permanently. And you can apply that decision once, or until you restart your Mac, quit the app or log out. You can then choose whether to allow the connection or to block it.

Install Little Snitch, and whenever an app tries to connect to the internet, you’ll get a notification. If you want something more user friendly, you’ll need a third-party firewall. The macOS firewall isn’t built to do this, but it is possible with PF (Packet Filter), macOS’s more advanced firewall that can only be controlled via the Terminal command line. That includes malware, which may try to send your data to hackers. In that scenario, you might be at risk of poor security or even a fake network.Īnother good reason to use a firewall is to control which Mac apps can connect to the internet. One such case is when you’re connected to a public network - for example, if you hook your MacBook up to wi-fi in a hotel. The combination of these factors is why Apple doesn’t make a big deal about the macOS firewall.īut there are times when a firewall app can be a handy thing to have on your Mac. On top of that, your router will also have its own firewall, so in most cases you don’t need any extra protection. That’s partly due to the fact macOS doesn’t run services that listen for network connections.

Specifically the fact that Mac users generally don’t need any extra firewall software to be enabled.

But macOS comes with a firewall built in - and by default, it’s turned off. Best balance of cost and features: Vallumīefore buying a firewall for your Mac, you first have to decide whether you actually need one.
