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

Coil Technologies is a small technology company specializing in Web Monetization through the Interledger protocol. The company offers subscription memberships for users to access monetized web content and provides tools for content creators to monetize their offerings. Recently, Coil announced the sunsetting of its products and the transition of Interledger stewardship to the Interledger Foundation, signaling a strategic shift in its business operations. The website reflects this transition with clear communication and resources for users. Technically, the website is built on modern web technologies including Webflow CMS, Google Fonts, and jQuery, hosted via Cloudflare. The site is mobile optimized and performs moderately well, with good SEO and basic accessibility features. However, some improvements could be made in accessibility and performance optimization. From a security perspective, the site uses HTTPS and has domain transfer protections in place, but lacks DNSSEC and explicit security headers such as Content-Security-Policy or X-Frame-Options. There is no published security or incident response policy, and no cookie consent mechanism is implemented despite having a privacy policy. These gaps suggest room for improvement in security posture and compliance. Overall, Coil.com presents a professional and trustworthy web presence with good business credibility and content quality. The domain is well-established and consistent with the company’s history. The site is safe for general audiences with no adult or questionable content. Strategic recommendations include enhancing security headers, implementing cookie consent, publishing security policies, and enabling DNSSEC to strengthen trust and compliance.

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"

  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

Coil Technologies occupies a niche market position as an early innovator in Web Monetization and Interledger technology. Its subscription-based business model targets both content consumers and creators, providing a platform for micropayments and monetization. The company’s decision to sunset its products and transfer stewardship to a neutral foundation indicates a strategic pivot towards ecosystem development rather than direct service provision. The company maintains a lean operation with a small size and focuses on technology innovation. Partnerships with the Interledger Foundation and related organizations are key to its ecosystem strategy. Revenue streams primarily come from membership subscriptions and platform services. The company’s transparent communication and clear privacy and terms policies enhance its credibility in the market.

Security posture

Coil.com demonstrates a moderate security maturity level. The use of HTTPS and domain transfer protection are positive indicators. However, the absence of DNSSEC and security headers reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of published security and incident response policies and absence of a vulnerability disclosure program indicate gaps in compliance and readiness. Data protection practices appear aligned with GDPR as indicated by the privacy policy, but cookie consent mechanisms are missing. Incident response contact channels are not publicly available, which could delay response to security events. Overall, the security posture is adequate but would benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a clear security policy and incident response plan accessible on the website.
  4. Add a cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  5. Establish and publish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built using Webflow CMS with integration of Google Fonts and jQuery libraries, hosted on Cloudflare infrastructure. The site is mobile optimized with responsive design and moderate performance. SEO is supported by proper meta tags and Open Graph tags, although no JSON-LD structured data was detected. Accessibility features are basic but present. The domain is stable and well maintained with a long registration history. Technical debt appears low, but opportunities exist to improve security configurations and performance optimizations. No critical technical risks were identified that would impact business operations.
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.
