- Fork: https://github.com/northpolesec/santa (actively maintained)
5. ESFang (WithSecure)
ESFang is a tool devised for modular consumption of EndpointSecurity Framework (ESF) events from the MacOS environment, designed to overcome issues like silent data dropping and strict event type consumption.
- Repository: https://github.com/WithSecureLabs/ESFang
- Language: Objective-C
- Features: Modular ESF event consumption, configurable event filtering
6. Swift ES Helper Libraries
A module to expose the Endpoint Security library to Swift, allowing you to import the C based Endpoint Security framework into your Swift code.
- Repository: https://github.com/knightsc/EndpointSecurity
- Purpose: Swift wrapper for ES C APIs
π― Recommendations for Your XDR/OXDR Development
Given your focus on security architecture through threat modeling and XDR platform development, Iβd recommend:
- Start with Red Canary Mac Monitor - Most actively maintained, Swift-based, comprehensive feature set
- Study AtomicESClient - Clean educational implementation for understanding ES fundamentals
- Reference Sinterβs architecture - Despite being archived, it solved many real-world authorization challenges
- Consider ESFang for telemetry patterns - Good reference for handling ES data ingestion at scale
The ecosystem shows that Swift is increasingly becoming the preferred language for macOS security tooling, aligning with Appleβs strategic direction and offering the memory safety advantages youβd want in security-critical code.
Rust and eBPF Requirements
π― Top Matches for Rust And EBPF Requirements

File System Monitoring with inotify Integration: ingraind uses eBPF to collect file access patterns and integrates with existing monitoring stacks like StatsD for metrics collection.
Network Connection Tracking: Aya-based projects demonstrate creating eBPF sampling profilers and network monitoring tools with performance optimization in mind.
π‘οΈ Security-by-Design Considerations
Threat Modeling Perspective: These projects address key attack vectors:
- Process execution monitoring for detecting malicious process spawning
- File system access tracking for data exfiltration detection
- Network connection monitoring for C2 communication detection
- Kernel module loading detection for rootkit prevention
Defensive Programming Practices:
- Pulsarβs Rust implementation provides memory safety and extreme performance even in constrained environments
- HarfangLabβs experience shows Rust EDR agents provide better performance with <50ms response times and can handle 500k events per minute
π Getting Started
For your XDR/OXDR platform development, Iβd recommend starting with Pulsar as it most closely matches your dependency requirements and provides a complete modular framework. The foniod project offers a more mature, production-ready codebase if you need immediate deployment capabilities.
All these projects demonstrate security automation patterns and provide excellent foundations for building custom security monitoring solutions with the exact capabilities you specified.
