The platform offers comprehensive tools for managing partners, tracking performance across multiple channels, and automating payments and reporting. Positioned as a trusted solution for top companies, Everflow emphasizes data-driven growth and operational efficiency. Technically, the website is built on a modern Webflow CMS platform, leveraging a robust tech stack including Google Tag Manager, Facebook Pixel, HubSpot, and Apollo.io for analytics and marketing automation. The site is well-optimized for performance, mobile responsiveness, and accessibility, with a clean, professional design that supports a positive user experience. From a security perspective, Everflow demonstrates strong practices including HTTPS enforcement, SOC 2 certification, and comprehensive privacy and GDPR compliance policies. While explicit security headers and incident response contacts are not prominently published, the overall posture is solid with no evident vulnerabilities or exposed sensitive data. Overall, Everflow presents a low-risk profile with a mature digital presence, strong business credibility, and adherence to privacy and security standards. The lack of WHOIS data due to privacy protection is common for SaaS businesses and does not detract from the legitimacy of the company.

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 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

Everflow operates in the competitive partner marketing and affiliate management sector, targeting businesses that seek to optimize revenue through diversified partner channels. Its curated marketplace and extensive integrations provide competitive advantages by simplifying partner discovery and campaign management. Revenue streams likely include subscription fees for platform access and managed payout services. The company actively engages its community through events, educational resources, and certification programs, indicating a strong ecosystem approach. The business model is SaaS-based with a focus on performance marketing, appealing to medium to large enterprises. The platform's emphasis on data transparency and automation positions it well for sustained growth and market differentiation.

Security posture

The security posture of Everflow is robust, supported by HTTPS encryption, SOC 2 certification, and detailed privacy and GDPR policies. The website employs multiple tracking and analytics tools, balanced with cookie consent mechanisms to maintain compliance. No critical vulnerabilities or exposed sensitive information were detected in the analysis. However, the absence of publicly available incident response contacts and a vulnerability disclosure policy represents an area for improvement. Overall, the company demonstrates a mature security culture appropriate for its industry and business size, with room to enhance transparency and responsiveness to security incidents.

Recommendations

  1. Publish explicit security headers such as X-Frame-Options and X-Content-Type-Options to improve protection against clickjacking and MIME sniffing.
  2. Establish and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  3. Provide clear incident response contact information on the website to facilitate timely communication in case of security events.
  4. Regularly review and update privacy and cookie consent mechanisms to ensure ongoing compliance with evolving regulations.
  5. Enhance transparency around data retention policies and third-party integrations to build greater user trust.

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries and integrations with marketing and analytics platforms such as HubSpot, Apollo.io, and Facebook Pixel. The use of Google Tag Manager and embedded Walnut demos indicates a sophisticated approach to user engagement and data collection. Performance is optimized with CDN-hosted assets and responsive design for mobile devices. The technical implementation reflects a well-maintained infrastructure with minimal technical debt. Opportunities exist to further modernize security headers and improve incident response readiness to mitigate potential risks impacting business continuity.
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.
