No one here can represent Apple.
Apple includes built-in security and anti-malware software. Details: Apple Platform Security - Apple Support
Squint, and more than a little of the add-on anti-malware looks and works like malware too, but with an end-user license agreement and an installer.
Some of the better-known Mac anti-malware was caught and fined for collecting and reselling personally-identified metadata including online purchases. Not fined because they collected and sold that metadata, but fined because they didn’t disclose that activity in the end-user license agreement. And we all carefully read those agreements.
Some of the other better-known add-on anti-malware for macOS was showing a false positive for months, for a component of macOS.
None of the add-on anti-malware can scan the contents of your iPhone, as the built-in anti-malware blocks that. The add-on anti-malware can scan your network traffic and collect your metadata.
And the ever-popular add-on “coffee shop” VPNs, which badly solve a problem that hasn’t existed for a decade or so, but do so in a way perfect for collecting personally-identified metadata.
Or shorter: No. Not outside of environments end-point security, and those are administered by an IT group.
