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

Formspree is a US-based SaaS company founded in 2014 that provides a form backend, API, and email service tailored for developers and businesses seeking easy integration of custom forms without server code. The company enjoys a strong market position, trusted by over 500,000 users including freelancers, agencies, and Fortune 500 companies, with key clients such as Amazon, OpenAI, IBM, and Adobe. Their offerings include JavaScript and HTML form solutions, spam filtering powered by machine learning, and direct integrations with popular platforms, positioning them as a reliable form solution provider in the technology sector. Technically, the website is built using the Hugo static site generator and hosted on Cloudflare, leveraging modern analytics tools like Google Analytics, Amplitude, and PostHog for user behavior tracking. The site demonstrates excellent design quality, mobile optimization, and SEO practices, ensuring a fast and accessible user experience. However, some improvements could be made in security headers and cookie consent mechanisms to enhance privacy compliance. From a security perspective, Formspree enforces HTTPS, employs machine learning spam filters, and integrates reCaptcha and custom spam rules to protect form submissions. The domain registration data is consistent with the business claims, indicating legitimacy. While no critical vulnerabilities were detected, the absence of explicit security headers and incident response contacts suggests room for strengthening their security posture. Overall, Formspree presents a professional, trustworthy, and technically mature web presence with a solid business model and market reputation. Strategic enhancements in privacy compliance and security disclosures would further solidify their standing and user trust.

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

5 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Formspree operates in the technology sector as a SaaS provider specializing in form backend and email services for developers and businesses. Their competitive advantage lies in simplifying form integration without server code, appealing to a broad audience from freelancers to large enterprises. Revenue streams likely include subscription plans and premium features. The company maintains a robust partnership ecosystem with integrations to major platforms like Airtable, Slack, Salesforce, and Zapier. Growth indicators include a large user base and endorsements from Fortune 500 companies. The website content and branding reflect a consistent and professional approach, supporting their market presence and operational transparency.

Security posture

Formspree exhibits a mature security posture with enforced HTTPS, domain transfer protection, and advanced spam filtering using machine learning. The use of reCaptcha and custom spam rules further mitigates abuse risks. However, the lack of visible security headers (e.g., CSP, HSTS) and absence of a public vulnerability disclosure or security.txt file indicate potential compliance gaps. Incident response readiness is unclear due to missing contact channels for security issues. Data protection practices appear adequate, supported by GDPR compliance and privacy policies. Overall, the security culture is positive but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to harden the website.
  4. Introduce a cookie consent banner or mechanism to comply with privacy regulations and inform users about tracking.
  5. Provide clear incident response contact information, including security and abuse email addresses, to improve transparency and trust.

Notes

The website is built on a modern static site generator (Hugo) and hosted via Cloudflare, ensuring fast load times and robust CDN support. The tech stack includes JavaScript libraries for analytics and user tracking (Amplitude, PostHog, Google Analytics). The site is well-optimized for mobile devices and accessibility, with comprehensive meta tags and SEO-friendly structure. No deprecated or vulnerable libraries were detected in the provided content. Technical risks are minimal, though the absence of some security headers and cookie consent mechanisms represent areas for modernization and compliance enhancement.
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.
