Best Practices
Use Multiple Feeds
No single feed catches everything. Combine several for best coverage.
Check Confidence Levels
Not all entries are equal. High-confidence data is more reliable.
Monitor False Positives
Even good feeds occasionally include false positives. Have a whitelist ready.
Keep Feeds Updated
Stale threat data is almost useless. Ensure regular updates.
