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.

Priority findings

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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

Opium Protocol occupies a niche in the DeFi derivatives market, enabling users to create and trade decentralized derivatives without coding expertise. Its business model revolves around protocol fees, liquidity provision incentives, and governance token utility. The platform's partnerships with leading DeFi projects like 1inch, AAVE, UMA, and RealT enhance its market position and ecosystem integration. The presence of a DAO and grant programs indicates a community-driven growth strategy. Revenue streams likely include trading fees and staking rewards. The target audience is sophisticated DeFi users and developers seeking customizable financial instruments. The backing by reputable investors and contributors signals strong growth potential and market credibility.

Security posture

The security maturity of Opium Protocol is commendable, with multiple audits passed and an ongoing bug bounty program that incentivizes vulnerability reporting. The protocol architecture minimizes liquidation risks by avoiding margining at the base layer, reducing attack surfaces. However, the absence of DNSSEC and security headers on the website suggests room for enhancement in web security practices. No direct incident response contacts or security policies are published, which could be improved to bolster trust. Privacy compliance is partial, lacking cookie consent despite tracking usage. Overall, the platform demonstrates a proactive security culture but should address web security and privacy gaps to meet higher compliance standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  3. Add a cookie consent banner/mechanism to comply with privacy regulations and inform users about tracking.
  4. Publish explicit security policies and incident response contact information to improve transparency.
  5. Enhance privacy compliance by detailing data retention policies and GDPR adherence measures.

Technical notes

Notes

The website employs a modern tech stack including JavaScript frameworks, Swiper.js for UI components, and integrates with YouTube iframe API for video content. Analytics are managed via Google Analytics and Twitter tracking pixels, orchestrated through Google Tag Manager. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and good SEO practices. However, the lack of CMS identification suggests a custom or static site approach. Performance is moderate, with potential for optimization in loading times and accessibility features. The technical infrastructure supports the platform's complex DeFi functionalities but should improve security configurations and privacy mechanisms to reduce 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.
