The data on your Mac, which is often private or important, can be vulnerable to prying eyes, malicious hackers or other threats. Luckily, encryption software is here to help. Encryption is a good way to protect your data. This article talks about the best encryption software for Mac to protect your apps, emails, disks, folders, files and some other important or sensitive data. There’s even free Mac encryption software, which is also covered in the article.

 

Why do we encrypt?

You may keep private or confidential information, personal or work related, on your Mac, such as personal photos, bank information, business documents, etc. If the device is lost or stolen, the leak of information could potentially lead to fraud, blackmail, identity theft or other threats. Encryption makes your information inaccessible or unreadable by an unauthorized third party. That’s why Mac encryption apps can be helpful, if not necessary.

Cons

Also, I’d like to briefly talk about keystroke encryption software for Mac. Such software is supposed to protect users against keyloggers (which are often used to steal information like passwords). There’s actually no perfect software for this. Using this type of software isn’t a very effective way to protect against keyloggers. The more effective practice is to avoid keylogging malware in the first place.

Factors to consider when choosing the best encryption software for Mac

The type of encryption you need Some encryption apps such as AppCrypt are good at protect your apps, some excel at protecting files and folders, and some have a reputation for email encryption. It depends on your needs.

The level of security There are various encryption algorithms. Different apps may use different algorithms. Some are weak (but still helpful enough for many), and some are stronger. Certain Mac encryption apps with stronger security may be a bit hard to set up and use for inexperienced users.

Encryption speed The speed is a factor that many people would consider. When it comes to encrypting large files or even entire drives, the speed is particularly important.

Ease of use Encryption software that is too complex can be overwhelming to a novice. An intuitive and user-friendly one is better.

Open-source software or not There are some free encryption software for you to choose, but free things are not necessarily good, similarly, encryption programs you need to pay are not always good, but you always get choices to try the applications for free before you pay for it.

Final words

The above are the top 8 Mac encryption apps. All of them have their own features, advantages, and disadvantages. Before deciding which one to use, you’d better tested them to better understand the functions, speed, and compatibility. If the key feature satisfies your demands, you can first try the encryption software for Mac to lock your apps, emails, files, folders, USB drives, or other items.
