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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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.

Dark web exposure

Add-on

Leaked records that mention blackfish.co, from OffSeq Breach.

No leaked records found

Breach holds no records for blackfish.co right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

Blackfish operates in the technology sector as a service provider specializing in software development and design. Their business model focuses on delivering end-to-end digital solutions combining creative design and technical development. The company targets businesses requiring sophisticated digital products and branding, leveraging a strong portfolio of projects and client testimonials to maintain competitive advantage. Recognitions from Clutch and Deloitte Fast 50 enhance their market credibility. Their partnership ecosystem includes reputable industry platforms and media. Growth indicators include recent projects and active social media engagement. The company maintains a medium size with over 25 professionals and a presence in multiple countries through client work.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and domain registration protections such as clientDeleteProhibited status. However, DNSSEC is not enabled, which is a recommended enhancement for DNS security. No explicit security policies or incident response contacts are published, which could improve transparency and readiness. The use of multiple third-party analytics and tracking scripts introduces potential privacy and security considerations, though no vulnerable libraries or exposed sensitive data were detected. The absence of a security.txt or vulnerability disclosure page limits the ability for external security researchers to report issues. Overall, the security posture is solid but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  3. Add a security policy page and incident response contact information to improve transparency.
  4. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Consider adding a security.txt file or vulnerability disclosure page to facilitate responsible reporting.

Technical notes

Notes

The website is built on WordPress CMS with a custom theme and uses popular plugins such as Contact Form 7 and Yoast SEO. It integrates multiple analytics and tracking services including Google Analytics, Hotjar, Smartlook, and Facebook Pixel, indicating a mature approach to user behavior analysis and marketing. Video content is embedded via Vimeo, and DNS is managed through Cloudflare, though DNSSEC is not enabled. The site shows good mobile optimization and SEO practices with proper meta tags and structured data (JSON-LD). Performance is moderate, with some heavy visual elements and animations. Accessibility is basic but could be improved. Overall, the technical infrastructure supports a professional digital presence with room for security and performance enhancements.
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.
