在当今世界，Windows和Mac操作系统都已经内置了防火墙。在安全性方面，内置防火墙完成了一半的工作，而您首选的安全套件附带的防火墙则完成了剩下的工作。没有太多理由再考虑安装独立的个人防火墙了。
当然，在某些特定情况下，您希望确保绝对最低限度的安全性。这意味着您可能需要另一个防火墙层。与互联网上某些人所说的相反，仍有大量可用的防火墙产品可供选择，包括付费和免费的。
您应该考虑安装的最佳第三方防火墙(The Best Third-Party Firewall You Should Consider Installing)
补充一下已经说过的内容，您的WiFi路由器还具有自己的防火墙，可与设备操作系统的内置产品以及您选择的安全套件一起使用。它使用网络地址转换(T)( NAT ) 为每个设备(N)分配(NAT)一个(A)仅在本地网络中可见的范围内的 IP 地址。即便如此，对于某些人来说，这可能还不够。
还有一些极其罕见的情况，即计算机直接连接到互联网，在这种情况下，额外的防火墙将被证明是更有益的。在让您在路上，在咖啡馆或酒店房间使用公共WiFi的情况下，拥有路由器不会让您受益。这使您处于更容易受到网络攻击的不利位置。对于这些情况，您可能需要额外的防火墙或虚拟(P)(Virtual Private Network (VPN))私有(V)网络((N) VPN )。
幸运的是，尽管有些付费产品可能会试图在不必要的功能上欺骗您，但免费产品应该在现有功能的基础上提供大量额外的保护。

Do You Need a Third Party Firewall on Mac and Windows?
In today’s world, bоth Windows and Mac operating systems already come with a buіlt-in firewall. When it comes to security, the built-in firewall does half the job whіlе the firewall that comes with your preferrеd security suite does the rest. There’s not much reason to consider installing a standalone personal firewall anymore.
Of course, there are specific situations in which you’d want to ensure the absolute minimum of security. This would mean you may need another firewall layer. Contrary to what some may say on the internet, there are still plenty of available firewall products, both paid and free, from which to choose.
The Best Third-Party Firewall You Should Consider Installing
Just to add to what has already been said, your WiFi router also has its own firewall to go along with both the built-in product from your device’s operating system as well as your chosen security suite. It uses Network Address Translation (NAT) to assign each device an IP address within a range only visible within a local network. Even then, for some this may still not be enough.
There are also those incredibly rare cases where a computer connects directly to the internet, in which case, an additional firewall would prove more beneficial. In circumstances that place you on the road, using public WiFi either at a cafe or hotel room, having a router will not benefit you. This puts you in the unwanted position of being more vulnerable to cyberattacks. For these occasions, you may need an additional firewall or Virtual Private Network (VPN).
Luckily, although there are paid products that may attempt to swindle you on unnecessary features, the free ones should provide plenty of additional protection on top of what is already there.
Understand that most third-party firewalls will attempt to take control of how programs use your network and connect to the internet. This is to ensure security and limit the chances for a network breach. Adding another firewall can also help sure up any of the weaknesses of your existing security measures.
A top choice in third-party firewall protection is ZoneAlarm Free Firewall, and it has been for some time. When paired together with a top free antivirus, or its own built-in antivirus component, you have the foundation of a great security system.
ZoneAlarm is one of the most popular Windows firewalls available. It is light, easy to use, fully-featured, and free. One of the more useful features is the added benefit of connecting to DefenseNet, which is a live database of real-time threats that alert your firewall to incoming attacks.
The firewall includes a “stealth mode” which protects your connections from hackers, includes identity protection services, and blocks malware. It hides open ports, identifies abnormal traffic, disables malicious programs, and offers 5GB of online data backup vis iDrive. If you are in the US, you can call on the company for victim recovery assistance in the case of identity theft.
ZoneAlarm updates itself automatically and you can install it on Windows 7, 8, 8.1, and 10 operating systems. Anyone who uses the internet a lot, either for leisure or business, will find that it’s an excellent choice for home wifi networks and laptops looking to connect to public internet hubs.

All you’ll need to get started is an internet connection for the download and an email address for the activation.

What About MacOS?
Contrary to popular belief, MacOS can face serious issues when dealing with intruders just as Windows does. In similar fashion, the biggest threat to a MacOS device is when using the internet on a public connection. It’s in these moments where you’ll wish you had additional protection.
When it comes to Mac, there are two possible solutions for a third-party firewall based on your budget. Those in need of free support should look into Avast for Mac for their troubles. It’s been a large name in the antivirus market for some time now and offers great software packages that include firewalls.
Norton Antivirus and Vallum are preferential if you’re okay with spending a little money. Between the two, Vallum is the only one that contains a firewall app on its own. Its design complements the macOS firewall, capable of intercepting connections at the application layer and keeping them locked down until you decide how to proceed.
Vallum is the most recommended out of the three for your protection. It allows for a custom app list with customizable pre-defined rules to decide which apps are allowed access to the internet. You can either block or allow apps quickly and easily using the drag and drop support feature. Put a stop to outbound connections in varying ways such as geo-location, pre-defined scheduling, or a host of other methods.
Installing Vallum
Vallum serves as a great little tool to help monitor all of your applications’ connections. You can purchase a single license for $15 including a full money back guarantee within 15-days if unsatisfied with the product.

- Once downloaded, double click on the icon and allow it to install.
Vallum’s default configuration is unintrusive and will not require any interaction whatsoever. All you’ll need to do is drag and drop an app’s icon from Finder over into the main Vallum window if you want it blocked.
Vallum will remain in the corner of your Mac’s menu bar so that it doesn’t intrude and pollute your Dock or desktop.
