Passive website inspection

Website evidence report for visibility, usability and trust

We fetch the public pages of your site and surface concrete evidence: visibility, structure, page performance, accessibility and baseline technical security.

  • Public pages only
  • Email verification
  • No active security testing
  • Evidence-backed report

What is inspected

Multi-page inspections only start after email confirmation or another form of authorisation.

Bot protection: Cloudflare Turnstile. Technically required under § 25 (2) (2) TTDSG. See the privacy policy for details. Open privacy policy

The inspection only fetches publicly reachable pages. No logins, no port scans, no active security probing.

How the inspection runs

Four steps. Fully automated. Results in minutes.

  1. 1

    Enter domain

    Provide your domain and a business email. Authority is verified through your domain.

  2. 2

    Confirm email

    Click the confirmation link. That authorises the passive inspection.

  3. 3

    Public pages are inspected

    Up to 25 public pages are fetched and analysed for visibility, structure, performance, accessibility and passive security.

  4. 4

    Read the short report

    You get the result link by email — with score, top findings and a link to the full evidence report.

  5. 5

    Request the full report or implementation

    After reading the short report you can unlock the full evidence report or request implementation.

What is inspected

  • Discoverability: indexing, titles, descriptions, structure
  • Usability: mobile rendering, forms, obvious blockers
  • Technical: page performance, redirects, image and cache hints
  • Baseline security: TLS, security headers and cookie hints from normal page loads

What is not inspected

  • No protected areas
  • No exploitation of weaknesses
  • No password, login or port testing
  • No security testing without a written engagement

From the passive short check to implementation

The short check and the full evidence report inspect public pages only — no port scanning, no exploit probes, no testing of authenticated areas. After the report we implement the fixes. A penetration test is a separate engagement that requires a signed scope.

10+ years enterprise experience

Penetration tests and implementation are delivered by engineers with more than ten years of experience in enterprise software and security.

For agencies & partners

Inspect client domains with authority proof

When your email does not match the target domain, prove authority via a DNS TXT record or request manual approval. Built for agencies inspecting client sites.

  • DNS TXT verification for cross-domain inspections
  • Lead dashboard for your pipeline
  • White-label report delivery (on request)
  • API access for automated inspections

Frequently asked questions

Everything important about the passive short inspection.

  • So we can confirm that the requester is connected to the domain. For agencies and external operators, DNS TXT verification or a manual approval are available.

  • Yes. Authorise client domains via DNS TXT record or operator approval, without needing an email at the client domain.

  • The full evidence report is €49 (no VAT charged under § 19 UStG, German small-business rule). It includes every finding with evidence, a prioritised action plan, a PDF download, and unlimited follow-up audits for 90 days.

  • No. The short inspection is purely passive — only public pages. Active testing is a separate engagement with a signed scope.
