Web Security Tools
Identify exposed services with port scanning, audit TLS configuration for weak ciphers and outdated protocol versions, check HTTP security headers for missing or misconfigured policies, and probe for common web vulnerabilities — all run from our network against any public host. More aggressive scanning tools require a login to prevent abuse. For continuous security posture monitoring, pair these with SSL Monitoring and HTTP Monitoring →
Vulnerability Scanners
-
Port Scanner
Polite TCP-connect port scan of a single public host (max 128 ports) with optional banner grab.
-
Web Vulnerability Scanner login
Scan a web server for known vulnerabilities, misconfigurations, and dangerous files.
-
TLS Implementation Fingerprinter login
Identify the TLS stack and version behind a server by probing its handshake behaviour.
-
HTTP Security Headers Grader login
Fetch a URL and grade its HTTP security headers — CSP, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, and more.
-
HSTS Preload Checker login
Verify whether a domain qualifies for and is listed on the HSTS preload list.
-
CSP Policy Evaluator login
Parse and grade a Content-Security-Policy header, flagging unsafe directives and common bypass vectors.
-
WordPress Scanner login
Scan a WordPress site for vulnerable plugins, themes, weak passwords, and known CVEs.
-
CMS Vulnerability Scanner login
Scan Drupal, SilverStripe, and Moodle installations for known vulnerabilities and misconfigurations.
-
Multi-CMS Scanner login
Scan WordPress, Joomla, and Drupal sites for vulnerabilities, outdated components, and common misconfigurations.
-
OWASP ZAP Web Scanner login
Full dynamic application security testing (DAST) scanner — crawls and probes a web application for OWASP Top 10 vulnerabilities.
-
Web Application Scanner login
Scan a web application for XSS, SQL injection, file inclusion, XXE, and other common vulnerabilities.
-
Threat Surface Probe login
Run community-maintained templates against a target to detect CVEs, exposed panels, misconfigurations, and default credentials.
-
OCSP Revocation Checker login
Query the OCSP responder for a certificate and verify it has not been revoked.
-
CAA Record Checker login
Look up a domain's CAA DNS records to verify which Certificate Authorities are authorised to issue certificates for it.
-
Exposed Admin Panel Detector login
Probe a web server for exposed admin panels, login pages, and sensitive paths — /wp-admin, /.env, /.git, /phpmyadmin, and similar.
-
Site Exposure Scanner
Probe a website for exposed config files, backup dumps, admin panels, and missing security headers — the same ~120 checks attackers run.
-
Site Standards Check
Verify a site publishes security.txt, robots.txt, sitemap.xml, app-linking files, and other well-known disclosure standards.
-
Deep TLS Security Audit login
Exhaustive TLS audit — protocol support, cipher suites, certificate chain, and 20+ known vulnerability checks (Heartbleed, ROBOT, POODLE, BEAST, and more).
Monitor this automatically
NetTests can run these checks on a schedule, preserve historical results, compare changes over time, and alert you the moment something breaks.
