About this plugin
Techbox Firewall is a fast, lightweight Web Application Firewall (WAF) for WordPress. It inspects every
request and blocks common attacks — SQL injection, cross-site scripting (XSS), remote code execution,
directory traversal, malicious bots, and bad requests.
Techbox Firewall is part of the Techbox Shield family and is designed to pair with
Techbox Login Security for complete front-door
protection: the firewall stops malicious requests, while Login Security guards the login itself.
What you get
- WordPress-layer WAF — loads early and screens every request, on any host, no.htaccess or server
changes required.
- Core attack rules — SQL injection, XSS, RCE, LFI/RFI, path traversal, malicious user-agents and
bad bots, and anomalous requests.
- Signed rule updates — optional (off by default); enable weekly or daily when you want fresher rules, verified before apply.
- Learning mode — on by default so you can watch and log before you enforce.
- IP allow / block lists — block known-bad addresses and allow-list your own office or VPN.
- Activity log — see exactly what was blocked and why, with a clean, plain-English record.
- Safe-mode recovery — a built-in way back if a rule or setting ever gets in your way.
Built for real people, not just developers
Security software is often written for experts. Techbox Firewall is different: smart defaults,
plain-English settings, and a clear view of what it is blocking — so first-time site owners and seasoned
agencies both feel at home.
Privacy
Firewall logs, IP lists, and settings stay on your WordPress site. Logs may include IP addresses,
request paths, and matched rule IDs so you can audit blocks — remove or restrict access if your
policies require it.

External services
This plugin can optionally download fresher attack-detection signatures from a feed service
operated by Techbox Design. It is off on a fresh install and stays off until you switch it on.
- Service: https://feeds.techboxdesign.com/firewall/v1/ — a JSON signature document plus a
detached signature file.
- When: Only after an administrator turns on Allow this site to contact the Techbox
signature feed under Firewall → Rule updates. With that off, the plugin makes no request to
the service at all, from any trigger. With it on, you choose between manual checks only, weekly,
or daily.
- Data sent: An ordinary HTTPS GET via the WordPress HTTP API. No account, no licence key, and
no visitor personal data.
- What comes back: Detection signature data — a match expression per entry, plus a category,
a score, and which parts of a request to inspect. Every field is validated against an allow-list
and the document’s signature is verified before anything is stored. Nothing downloaded is
executed, evaluated, included, or unserialised, and no plugin, theme, or add-on is installed or
updated by this service. org only.
- If it is unavailable: The signatures bundled with the plugin are always active, so protection
does not depend on this service being reachable or enabled.
- Terms of Use: https://techboxdesign.com/terms-and-conditions/ (see “Optional signed rule
feed”)

You can withdraw permission at any time; doing so also cancels any schedule.
