One thing that often gets overlooked in these comparisons is distribution latency.

Detecting a phishing domain internally is one problem, but pushing a verified block to billions of browsers worldwide is a completely different operational challenge.

Systems like Safe Browsing have to worry about propagation time, cache layers, update intervals, and the risk of pushing a false positive globally. A specialized vendor can update instantly for a much smaller customer base.

That difference alone can easily look like a “miss” in snapshot-style measurements.
