Low risk. 3 critical or high findings in GDPR outside view, SSL/TLS and 1 other check.
Webflow is a leading SaaS technology company specializing in no-code website building, CMS, hosting, and optimization solutions. Founded in 2013 and headquartered in San Francisco, Webflow serves a broad audience including web designers, developers, agencies, enterprises, freelancers, and startups. The platform enables users to design, build, and launch custom responsive websites visually without writing code, positioning itself strongly in the no-code market segment with enterprise-grade offerings and extensive integrations. Technically, Webflow leverages a modern tech stack including its proprietary CMS, Amazon AWS hosting and DNS services, and integrates marketing and analytics tools such as Marketo, Datadog, Intellimize, and Drift chat. The website is well-optimized for performance, mobile responsiveness, accessibility, and SEO, reflecting a mature digital infrastructure and strong technical implementation. From a security perspective, Webflow enforces HTTPS, employs multiple security headers, and uses a reputable domain registrar with consistent WHOIS data. However, DNSSEC is not enabled, and there is no public vulnerability disclosure policy or security.txt file, indicating areas for improvement. Privacy compliance is well addressed with clear privacy and cookie policies and GDPR adherence. Contact information is primarily available via forms and structured data, with no explicit public emails or phone numbers. Overall, Webflow presents a high level of professionalism, trustworthiness, and technical maturity. The platform is well-positioned in the market with strong branding, comprehensive service offerings, and a secure, performant website. Strategic recommendations include enabling DNSSEC, publishing a vulnerability disclosure policy, and enhancing incident response contact transparency to further strengthen security posture and 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
3 findings rated critical or high. Fix these first.
GDPR outside view
These are the privacy signals visitors and data protection authorities look for under GDPR.
- 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
- GDPR Art. 7
- ePrivacy Art. 5(3)
- NIST PT-4: NIST SP 800-53 Rev. 5 PT-4: Consent
- High
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
- RFC 8996
- RFC 7568
- Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: tls_versions TLSv1.2, TLSv1.3
- NIS2 21(2)(h)
- IR 2024/2690 9.2(b): Implementing Regulation (EU) 2024/2690, Annex point 9.2(b): Cryptography
- NIST SC-8(1): NIST SP 800-53 Rev. 5 SC-8(1): Cryptographic Protection
- High
DNS health
DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.
- High
Weak SPF Policy
SPF record has permissive policy allowing any server to send email
What to do: Use -all or ~all qualifier for better email security
- High

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 notes
Notes
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.
