Added OpSec macOS Tool to Detection Category.

[Lennolium]

I added the macOS OpSec-enhancing Application 'swiftGuard' to the category 'Detection, Alerting and Automation Platforms'. If you think it would fit somewhere else, please feel free to edit.

It's a lightweight tool that safeguards your systems USB ports for any unauthorized access and initiates a shutdown or hibernation in case of threat detection.

Disclaimer:
I'm an computer science student and developed this app by myself. I did not want to offensively spam/advertise my work here. I really think, it would improve this curated list and help others.

Guidelines:

• Search previous suggestions before making a new one, as yours may be a duplicate.
• Make an individual pull request for each suggestion.
• Use the following format: [PACKAGE](LINK) - DESCRIPTION.
• New categories, or improvements to the existing categorization are welcome.
• Keep descriptions short and simple, but descriptive.
• End all descriptions with a full stop/period.
• Check your spelling and grammar.
• Make sure your text editor is set to remove trailing whitespace.
