Scanners
Apply one twa checklist across a domains file
Opinionated twa web audits, one pass over a domain list.
overview
What twa-loop does
twa-loop takes a file of domain hostnames and runs the same twa checklist on each one: security headers, cookie attributes, common development ports, and TLS posture. One run gives a hygiene read across an estate instead of a single site.
Flags match twa and apply per host. Enable -s for testssl certificate and cipher review, -w to also audit the www variant, and -d to skip development-port probes. Verbose mode (-v) writes detail to stderr.
Trickest runs twa-loop as a managed scanner node that reads a domains file and emits a file plus a results folder. Place it after subdomain enumeration or a live-host filter when you want one baseline for every host.

use cases
Where twa-loop fits
Baseline-audit a whole subdomain list
Feed twa-loop the output of subdomain discovery so every host gets the same header, cookie, and TLS checklist in one pass.
Find the odd host out
Run a consistent audit across the estate to surface the one host with a missing header or weak cipher while every other host is clean.
Include TLS review at scale
Enable -s so testssl runs against each domain, extending the audit to certificate validity and protocol versions for the whole list.
Cover apex and www everywhere
Turn on -w so both the apex and www host of every domain in the file are audited, catching per-host redirect and header drift.

Choosing twa-loop
Use twa-loop when you have a host list and want the same opinionated baseline on every domain. For a single host, use twa. For WAF fingerprinting or template CVE coverage, chain wafw00f or nuclei after it.
twa
Same checklist for one domain instead of a file.
nikto-list
Broader nikto checks over a host list. twa-loop stays a tighter, fixed audit.
wafw00f
Fingerprints the WAF in front of each host. Complements the twa-loop baseline.

Run twa-loop yourself
A file of domains feeds twa-loop, which runs the opinionated twa checklist against each host and writes the per-host audits as a queryable output.
