87/ 100Good

On September 11, 2026 the Site Spider crawled 279 pages and 146 assets of www.thompsonoptics.com, starting from https://www.thompsonoptics.com/. It scored 87 out of 100, a good result. 9 of 27 checks found something to fix, led by sitemap coverage (141), meta descriptions (103), heavy assets (4); 7 checks passed. Most of the points went to sitemap coverage (−3.5), meta descriptions (−3.4), heavy assets (−2.4). 11 checks found something the score does not count, listed as noted. 10 checks were not run because the crawl fetched nothing for them. The list below shows each check's result, the fix plan, when present, explains what to do first, and the security review at the end of the page covers headers, transport, libraries and exposed files.

Security review

Written by gpt-4o-mini from 16 checks over the crawl

This review identifies security issues on your website. Key concerns include missing HTTP Strict Transport Security (HSTS), which could expose users to interception. Additionally, sensitive information like a Google API key is publicly accessible, and server software version details are disclosed. These issues necessitate prompt action to enhance your site's security.

  • 0 high
  • 2 medium
  • 2 low
  • 1 info
  1. 1

    Missing HTTP Strict Transport Security (HSTS)Medium

    Why it matters: Without HSTS, users may be intercepted when accessing the site without HTTPS.

    Fix: Implement the Strict-Transport-Security header with a value of 'max-age=31536000; includeSubDomains'.

    Evidence: HTTP Strict Transport Security

  2. 2

    Leaked Google API KeyMedium

    Why it matters: A publicly visible API key can be abused if not restricted.

    Fix: Restrict the API key by HTTP referrer in the Google Cloud console.

    Evidence: Keys and secrets in page code

  3. 3

    Server Version DisclosureLow

    Why it matters: Revealing server software versions allows attackers to exploit known vulnerabilities.

    Fix: Configure your server to hide version information by setting 'server_tokens off' in nginx.

    Evidence: Software version disclosure

  4. 4

    Third-Party Scripts Without Integrity ChecksLow

    Why it matters: Scripts from other domains can be compromised, affecting your site.

    Fix: Implement Subresource Integrity (SRI) for all external scripts, or establish a Content-Security-Policy that includes these domains.

    Evidence: Third-party scripts

  5. 5

    Disclosure of Sensitive Paths in robots.txtInfo

    Why it matters: These paths may be targeted by attackers but do not restrict access.

    Fix: Ensure proper access controls are in place beyond just listing in robots.txt.

    Evidence: Sensitive paths in robots.txt

  • FoundSoftware version disclosureLow

    Responses reveal the exact server or framework version, which lets an attacker look up known vulnerabilities for it without guessing.

    • server: nginx/1.26.3 (425 responses)
  • FoundKeys and secrets in page codeMedium

    1 credential-like value found in code served to every visitor: Google API key.

    • Google API key AIzaSy…uY (39 chars) in https://www.thompsonoptics.com/: browser keys are expected in pages, but must be restricted by HTTP referrer and API in the Google Cloud console
  • NoteThird-party scripts

    Scripts run from 2 other domains without Subresource Integrity, so a compromise of any of them changes what runs on this site. (Tag managers and analytics rarely support SRI; a Content-Security-Policy that names these hosts is the usual control.)

    • www.googleadservices.com (40 script tags)
    • ecpbuilder.com (37 script tags)
  • NoteSensitive paths in robots.txt

    robots.txt lists 2 paths that look private. robots.txt is public and does not restrict access, so it doubles as a map for anyone probing the site; those paths need real access control.

    • Disallow: /wp-admin/
    • Disallow: /wp-login.php
