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

BlockSurvey is a privacy-first survey platform founded in 2019, offering secure, AI-powered survey creation and analysis tools. Positioned as a privacy-conscious alternative to traditional survey providers, it emphasizes end-to-end encryption, data ownership, and compliance with major security standards such as SOC2, ISO 27001, HIPAA, and GDPR. The platform targets businesses, enterprises, researchers, students, and non-profits seeking secure and efficient survey solutions. Technically, the website is built on Angular 13, hosted behind Cloudflare DNS, and uses modern web technologies with strong mobile optimization and SEO practices. Security posture is strong with HTTPS, encryption, and no ads or trackers, though DNSSEC is not enabled and explicit security headers are not visible in the provided data. Privacy compliance is good but lacks explicit privacy and cookie policies in the analyzed content. Overall, the site demonstrates high professionalism, trustworthiness, and technical maturity.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. 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

  3. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

BlockSurvey operates in the technology sector, focusing on privacy-centric survey tools enhanced with AI capabilities. Its business model is SaaS-based with free and paid tiers, including discounts for students and non-profits. The company leverages certifications and compliance to differentiate itself in a competitive market dominated by legacy survey platforms. Customer testimonials and social proof reinforce its market position. The company maintains a consistent brand and strong social media presence. The use of privacy protection in WHOIS is justified given the nature of the business. No suspicious patterns or inconsistencies were found in domain registration or website content.

Security posture

The security posture of BlockSurvey is robust, with end-to-end encryption of survey data, no ads or tracking, and compliance with recognized standards (SOC2, ISO 27001, HIPAA, GDPR). The website uses HTTPS exclusively and avoids common privacy pitfalls. However, the absence of DNSSEC and explicit security headers in the provided data suggests room for improvement. No incident response or vulnerability disclosure information is publicly available, which could be enhanced to improve transparency and trust. No vulnerabilities or exposed sensitive data were detected in the content analyzed.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish explicit privacy and cookie policies with clear consent mechanisms to improve privacy compliance.
  3. Add a security.txt file or dedicated page for vulnerability disclosure and incident response contacts.
  4. Implement and explicitly declare security headers such as Content-Security-Policy and X-Frame-Options.
  5. Maintain transparency by providing incident response contact channels and updating compliance documentation regularly.

Technical notes

Notes

The website is a modern single-page application built with Angular 13, leveraging Cloudflare for DNS and likely CDN services. It uses custom fonts and optimized images, with Google Tag Manager for analytics. The site is mobile-optimized, fast-loading, and SEO-friendly with proper meta tags and structured data. No CMS detected, indicating a custom-built platform. The technical infrastructure supports the business model well, though enabling DNSSEC and enhancing security headers would further strengthen the technical security posture. No technical debt or legacy technology indicators were found.
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.
