XProtect, also known as “File Quarantine”, is the in-built anti-malware system for Mac OS operating systems. It is in effect, Apple’s analog of Microsoft’s Windows Defender suite. XProtect is a Mac’s primary defense against infection from malicious software such as viruses, trojans, and spyware.
How Does XProtect Work?
XProtect is installed on a Mac by default, and will also automatically update as part of a set routine. Unlike many other anti-malware programs, XProtect is very light on system resources and runs silently in the background. A fundamental difference with other programs is that it is not constantly monitoring the system (hence why it is CPU-light). Instead, it mostly comes into play just to scan downloads. When an application initiates a download, XProtect will check the file and compare its contents to known virus definitions. If a potential threat is discovered, the user will be alerted.
Is XProtect Secure Enough
While Apple has made improvements to XProtect due to a changing threat environment, it is nonetheless intended to offer basic protection — and not much more. In addition, because it focuses solely on major malware-types, it arguably neglects lesser-known grayware such as Potentially Unwanted Programs (PUPs), crypto mining software, and annoying adware.
That said, it is not invincible against traditional malware either. Last year for example, it was reported that the AdLoad trojan was slipping through XProtect’s defenses and infecting Macs. Once a Mac is infected, AdLoad installs a Man-in-The-Middle (MiTM) web proxy to hijack search engine results, and also installs its own malicious LaunchAgents. At the same time, there are other threats capable of bypassing XProtect, such as Shlayer, which has reportedly infected over 10% of all Apple computers.
With the above in mind, it is quite clear that while XProtect is better than no protection, it is not sufficient to fully protect your Mac in the context of an ever-changing threat environment.
