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

BuySellAds is a technology-driven advertising platform that connects publishers and marketers through powerful advertising solutions including native ads, programmatic ads, and exclusive ad networks. The company targets advertisers seeking contextual advertising across websites, newsletters, and podcasts, and publishers looking to monetize their audiences. The website demonstrates a mature digital presence with professional design, clear navigation, and strong branding supported by client testimonials and success stories. Technically, the site is built on HubSpot CMS with modern JavaScript frameworks and uses HTTPS with analytics integration. However, the absence of explicit privacy and cookie policies, lack of security headers, and missing WHOIS domain registration data present areas of concern for security and trust. Overall, the platform is credible and functional but would benefit from enhanced transparency and security best practices.

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.

  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

  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

BuySellAds operates in the advertising technology sector, offering a marketplace and tools for publishers and advertisers to connect. Its business model includes self-serve platforms, programmatic solutions, and curated ad networks targeting niche audiences such as developers, crypto enthusiasts, and designers. The company has established partnerships with notable brands and leverages HubSpot for marketing and analytics. The presence of multiple product offerings and a diverse audience segmentation indicates a strategic approach to market penetration and revenue diversification. The lack of publicly available WHOIS data is a minor risk factor but does not detract significantly from the company's operational credibility.

Security posture

The website enforces HTTPS and uses secure login portals for advertisers and publishers, indicating a baseline security posture. However, the absence of common security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is publicly available, which limits transparency and preparedness perception. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The security posture is adequate but could be improved by implementing recommended headers, publishing security policies, and enhancing privacy compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against web vulnerabilities.
  3. Publish a vulnerability disclosure policy and incident response contact information to increase transparency and trust.
  4. Improve accessibility features to meet compliance standards and enhance user experience for all users.
  5. Verify and publish domain WHOIS information to strengthen domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built on HubSpot CMS, leveraging Alpine.js for interactivity and SVG for graphics, ensuring a modern and responsive design. It uses web fonts efficiently and loads analytics scripts from HubSpot. The site is mobile optimized with responsive layouts and accessible navigation. Performance appears moderate with asynchronous script loading. However, there is room for improvement in SEO metadata completeness and accessibility compliance. The technical infrastructure supports a professional user experience but should incorporate enhanced security headers and privacy features to align with best practices.
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.
