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

Slickstream is a technology company specializing in providing engagement tools for bloggers and website publishers. Their SaaS platform offers advanced search, content discovery, user engagement features, and analytics to improve visitor experience and increase traffic. The company positions itself as a niche provider focused on enhancing website engagement with minimal technical integration. Technically, the website is built on the HubSpot CMS platform, utilizing modern JavaScript libraries and marketing tools such as Google Analytics and Facebook Ads Pixel. The site is mobile optimized and demonstrates good SEO and accessibility practices. Security posture is solid with HTTPS enforced and secure forms, though explicit security headers and incident response policies are not publicly documented. Privacy and cookie policies are comprehensive and GDPR compliant. However, the absence of WHOIS data for the domain reduces trustworthiness and raises questions about domain registration transparency. Overall, the website is professional and trustworthy, but the domain registration opacity is a notable risk factor.

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

Slickstream operates in the technology sector, targeting bloggers and content publishers with a SaaS business model. Their key services include search, discovery, engagement tools, and analytics portals. The company leverages partnerships and case studies with known blogs to demonstrate effectiveness. Their marketing ecosystem includes HubSpot and Google platforms, supporting lead generation and user tracking. The business appears small but focused, with consistent branding and positive user testimonials. The lack of direct contact emails or phone numbers suggests a preference for contact via web forms. The company maintains a privacy-conscious approach with clear policies. The absence of WHOIS data is unusual and may warrant further investigation to confirm legitimacy.

Security posture

The website enforces HTTPS and uses secure forms, indicating a baseline security maturity. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no publicly available security policy or incident response information, limiting transparency. No vulnerabilities or exposed sensitive data were found in the HTML content. Tracking and marketing scripts are used responsibly with consent mechanisms in place. Overall, the security posture is good but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide direct company contact emails and phone numbers to improve business credibility and user trust.
  5. Investigate and resolve the lack of WHOIS domain registration data to ensure domain legitimacy and reduce risk.

Technical notes

Notes

The website is built on the HubSpot CMS platform, integrating modern JavaScript libraries such as jQuery and Tiny Slider for UI components. It uses Google Analytics and Google Tag Manager for analytics and marketing tracking, along with Facebook Ads Pixel for retargeting. The site is mobile responsive with good SEO meta tags and Open Graph data for social sharing. Performance is moderate, likely influenced by external scripts and HubSpot hosting. Accessibility is basic but present. There is no evidence of outdated or vulnerable libraries. The technical infrastructure is solid for a small SaaS provider but could benefit from performance optimizations and enhanced security headers.
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.
