Formstack is a well-established SaaS company founded in 2006, specializing in no-code form building, document generation, eSignatures, and workflow automation solutions.

The website demonstrates a mature technical infrastructure leveraging modern web technologies such as Webflow CMS, Google Tag Manager, Microsoft Clarity, and Drift chatbot, indicating a high level of digital maturity and performance optimization. Security posture is robust with HTTPS enforcement, security headers, and consent management, though explicit security policies and incident response contacts are not publicly disclosed.

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

2 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 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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Formstack operates in the technology sector, offering SaaS solutions that integrate with major platforms like Salesforce, Amazon S3, PayPal, Stripe, and HubSpot. Their business model focuses on subscription-based revenue streams targeting enterprise and mid-market customers across industries such as healthcare, finance, education, and software. The company maintains a strong partnership ecosystem and provides extensive resources including blogs, webinars, and customer stories to support customer engagement and growth. The presence of multiple physical offices in the United States and a consistent brand identity further reinforce their market credibility.

Security posture

The website exhibits a mature security posture with HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR compliance. Use of reCAPTCHA and bot protection tools enhances security against automated threats. However, the absence of a publicly accessible security policy, incident response contact, and vulnerability disclosure program represents gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the content. The overall security maturity is good but could be improved by publishing formal security documentation and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and practices.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance with standards such as WCAG.
  5. Maintain WHOIS transparency or provide justification for privacy protection to improve trust.

Technical notes

Notes

The website is built on Webflow CMS and leverages a modern technology stack including Google Tag Manager, Microsoft Clarity, Drift chatbot, and Osano for consent management. Performance is optimized with fast loading times and mobile responsiveness. SEO is well addressed with proper meta tags and structured data (JSON-LD). The technical implementation is robust with no visible technical debt or deprecated libraries. Opportunities exist to further improve accessibility and publish more detailed security and compliance documentation to reduce operational risks.
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.
