Security score

47/100

Risk levelHigh

0–100, higher is better. How it is calculated

The website finisar.com is currently inaccessible, returning a 400 Bad Request error with minimal HTML content served by openresty. Due to this, no business, security, or compliance information can be extracted or analyzed. The lack of accessible content prevents assessment of the company's market position, services, or technical infrastructure. The website appears to be blocked or misconfigured, resulting in a critical failure to deliver content. From a technical perspective, the site shows no metadata, scripts, or forms, indicating either a server misconfiguration or intentional blocking. No security headers or SSL configuration details are available, which raises concerns about the site's security posture. The absence of privacy, cookie, or terms of service policies further indicates non-compliance with common regulatory standards. Security posture evaluation is severely limited due to the lack of accessible content. No incident response contacts, security policies, or vulnerability disclosures are present. The site likely fails to meet basic security and privacy compliance requirements. Overall, the risk assessment is high due to the inability to verify any security controls or business legitimacy. Strategic recommendations include resolving the server error to restore website accessibility, implementing HTTPS with proper SSL configuration, adding comprehensive privacy and cookie policies, and publishing clear contact and security information to improve trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

No business intelligence data could be extracted due to inaccessible website content. No information on market positioning, business model, revenue streams, or partnerships is available. The domain finisar.com is known externally as a technology company specializing in optical components, but this cannot be confirmed from the current website data.

Security posture

The current security posture cannot be assessed due to lack of accessible content. No security headers, SSL details, or security policies are present. The site returns a 400 error, which may indicate misconfiguration or blocking. No evidence of compliance with GDPR or other regulations is found. Incident response readiness and vulnerability disclosure practices are unknown.

Recommendations

  1. Resolve the 400 Bad Request error to restore website accessibility.
  2. Implement HTTPS with valid SSL certificates and verify configuration.
  3. Add comprehensive privacy and cookie policies with consent mechanisms.
  4. Publish clear contact information including security incident contacts.
  5. Implement security headers and conduct vulnerability assessments.

Technical notes

Notes

The website currently serves only a minimal 400 Bad Request error page generated by openresty/1.25.3.1. No HTML metadata, scripts, or forms are present. No CMS or frameworks can be detected. Hosting provider details are unknown. Performance and mobile optimization cannot be evaluated. The site lacks SEO and accessibility features. This indicates a critical technical failure or intentional blocking preventing content delivery.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
