What it’s for
A template-driven scanner: it checks targets against a large community library of known issues and misconfigurations.
Where it shines
- Fast, and great for wide coverage or CI pipelines
- Community templates cover a lot of ground
Where it falls down
- Template quality varies, so false positives happen
- It finds the known, not the novel — and can be loud
My take
