Advanced Security Scanning

RedKit is mlab's infrastructure scanning engine. It lets you run targeted security assessments on domains you own, combining reconnaissance, vulnerability detection and compliance checks in a single configurable scan.

RedKit requires domain ownership verification before scanning. You must add a DNS TXT record to prove you control the target domain.

What is RedKit

RedKit is an automated security scanner that runs a suite of modular checks against your web infrastructure. Unlike standard domain scans, RedKit performs deep, active testing with configurable modules across three categories:

  • Recon — passive and active discovery (subdomains, ports, technologies, DNS, WAF detection)
  • Vulnerability — active testing for common web vulnerabilities (SQLi, XSS, SSRF, open redirects, etc.)
  • Compliance — verification of security best practices (CSP, DNSSEC, TLS ciphers, cookie flags, etc.)

Each scan produces a detailed report with findings categorized by severity, exportable as a PDF document.

Domain verification

Before scanning, you must prove ownership of the target domain by adding a DNS TXT record. This prevents unauthorized scanning of third-party infrastructure.

  • Go to Account → Infrastructure
  • Enter the domain you want to scan
  • Add the provided TXT record to your domain's DNS configuration
  • Click verify — once confirmed, the domain appears in your RedKit dashboard

Verified domains persist across scans. You only need to verify a domain once.

Running a scan

Once your domain is verified, you can launch a scan from the RedKit dashboard:

  • Select the verified domain you want to scan
  • Optionally specify a subdomain target (e.g. www, api)
  • Enable or disable individual modules in each category
  • Click Launch scan

Scans run asynchronously. You can close the page and come back later — the results page auto-refreshes every 30 seconds until the scan completes.

Scan quotas depend on your plan: Free (1 lifetime), Pro (5/month), Team (20/month), Enterprise (unlimited).

Results & reports

When a scan completes, findings are presented as individual cards grouped by module. Each finding includes a severity level:

Critical High Medium Low Info

Each finding card shows the module name, a description of the issue, and evidence data when available.

  • A severity summary bar at the top provides a quick overview
  • The full scan history is available at RedKit → History
  • Click Export PDF to generate a printable report with cover page, severity breakdown and detailed findings

Quotas & plans

RedKit scans consume quota based on your subscription plan. The remaining quota is displayed on the scan configuration page before launch.

  • Free — 1 scan (lifetime)
  • Pro — 5 scans per month
  • Team — 20 scans per month
  • Enterprise — Unlimited
