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

Plume.org is a blockchain-focused platform specializing in scaling Real World Assets (RWAs) by transforming traditional assets into crypto-native financial tools. The company, MetaBase58 Cayman Limited, operates a public blockchain called Plume Chain and offers a suite of products including stablecoins, developer tools, and wallets tailored for RWA finance. The website targets developers, financial technology users, and blockchain ecosystem participants, positioning itself as an emerging player with a growing partner ecosystem. Technically, the site leverages modern web technologies such as Webflow CMS, Cloudflare DNS, Google Tag Manager, and Cookiebot for consent management, demonstrating a mature digital infrastructure with good mobile optimization and SEO practices. Security-wise, the site enforces HTTPS, uses domain locking statuses, and implements cookie consent, but lacks DNSSEC and explicit security or incident response policies. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though it could improve transparency by publishing terms of service and contact information.

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

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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

Plume operates in the technology and finance sectors, focusing on blockchain infrastructure for RWAs. Its business model revolves around providing blockchain products and developer tools to enable seamless integration and scaling of real-world assets onchain. The company has established partnerships with notable ecosystem players such as Nest Credit and Ondo Finance, enhancing its market position. The platform's offerings include a native stablecoin (pUSD), ETH liquid staking token (pETH), and a wallet solution (Plume Passport), indicating diversified revenue streams and a comprehensive ecosystem approach. The presence of accelerator programs and developer hubs suggests a growth-oriented strategy targeting blockchain developers and financial institutions. Despite the absence of direct contact details on the website, the company maintains a professional online presence with consistent branding and quality content.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and domain status protections preventing unauthorized changes. The use of Cookiebot indicates compliance with cookie consent regulations, and Google Analytics is implemented with transparency. However, the absence of DNSSEC is a notable security gap that could expose DNS spoofing risks. No security.txt or vulnerability disclosure policies are published, limiting external security engagement. The lack of explicit incident response contacts and security policy pages reduces transparency in handling security events. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security maturity is good but could be enhanced by adopting DNSSEC, publishing security policies, and providing incident response contacts.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a security.txt file and a dedicated security policy page to facilitate vulnerability reporting and improve transparency.
  3. Add explicit incident response contact information, such as security@ or abuse@ email addresses.
  4. Create and publish a terms of service page to clarify user agreements and legal protections.
  5. Include clear contact information such as company emails or phone numbers to improve trust and user support.

Technical notes

Notes

The website is built using Webflow CMS and hosted with Cloudflare DNS services, leveraging modern front-end technologies including HTML5, CSS3, JavaScript, Google Fonts, and Lottie animations for enhanced user experience. Google Tag Manager and Cookiebot are integrated for analytics and privacy compliance. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site uses multiple external trusted domains for content delivery and partner integrations. Technical risks are minimal but include the lack of DNSSEC and limited accessibility compliance. Overall, the technical infrastructure supports a professional and scalable online presence suitable for a blockchain technology company.
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.
