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

Whalebone, s.r.o. is a cybersecurity company specializing in user-centric, no-installation security solutions aimed at telcos, ISPs, enterprises, and government institutions. The company positions itself as a global leader in telco cybersecurity deployments and leads the DNS4EU project to secure DNS resolution for EU citizens and institutions. Their key products include Whalebone Aura, Immunity, and Peacemaker, targeting different market segments with multi-layered digital protection services. The website reflects a professional and consistent brand with clear messaging and customer testimonials, indicating strong market presence and trust. Technically, the website is built on HubSpot CMS and integrates modern marketing and analytics tools such as Google Analytics 4, Google Tag Manager, Facebook Pixel, and LinkedIn Insight Tag. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Security posture is strong with HTTPS enforced and secure forms, though explicit security headers and vulnerability disclosure mechanisms are absent. The WHOIS data is incomplete and malformed, limiting direct verification of domain registration details. Despite this, the website content and business information suggest legitimacy. Contact information includes a company email and a contact form, but no explicit phone numbers or social media links were found. Privacy and cookie policies are not explicitly present, indicating an area for compliance improvement. Overall, Whalebone demonstrates a mature digital presence with a solid security foundation but should enhance transparency around privacy policies, incident response, and domain registration details to improve 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.

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"
  References

  - CAPEC-103
  - ASVS V3.4.6
  - OWASP Secure Headers: OWASP Secure Headers Project recommends X-Frame-Options: deny
  - RFC 7034
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

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.

Counted in this score

SSL/TLS: 75
Security headers: 45
Email security: 70
DNS health: 65
Network security: 0
GDPR outside view: 83
Average: 56
After the cap: 49

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 · found on this site
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

Whalebone operates in the cybersecurity sector with a focus on telecommunications, government, and enterprise markets. Their business model leverages SaaS-like cybersecurity products that require no installation, facilitating mass adoption and reducing churn. The company has established partnerships with major telcos such as Tele2, Telefonica, and A1, and serves over 300 telecom providers globally. Leadership in the DNS4EU project highlights strategic positioning within the EU cybersecurity landscape. Revenue streams likely include B2B and B2G contracts for cybersecurity services. The company targets a broad audience from telcos to end consumers, emphasizing user-centric security. Growth indicators include active participation in EU projects and multiple customer testimonials. The partnership ecosystem is robust, with visible logos of prominent clients and collaborators. Operationally, the company uses HubSpot for marketing and analytics, indicating a modern digital marketing approach.

Security posture

Whalebone's website enforces HTTPS, ensuring encrypted communications. The site uses secure forms with required fields, minimizing input risks. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense in depth. No security.txt or vulnerability disclosure policy is present, which could hinder coordinated vulnerability reporting. The WHOIS data is incomplete, limiting domain trust verification. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The company does not publicly display incident response or security policy information, which could be improved to demonstrate security maturity. Overall, the security posture is good but could benefit from enhanced transparency and technical hardening.

Recommendations

Publish explicit privacy and cookie policies with clear GDPR compliance statements.
Implement and publish a security policy and incident response page to improve transparency.
Add security headers such as CSP, HSTS, and X-Frame-Options to strengthen site security.
Provide a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
Verify and publish complete WHOIS domain registration information or use layered access to improve trust.

Technical notes

Notes

The website is built on the HubSpot CMS platform, leveraging modern web technologies and marketing integrations including Google Analytics 4, Google Tag Manager, Facebook Pixel, and LinkedIn Insight Tag. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured JSON-LD data describing the organization. Performance is moderate, with asynchronous loading of scripts and deferred CSS. The site uses custom fonts (Inter and Poppins) and FontAwesome icons. No outdated or vulnerable libraries were detected. The hosting provider is not explicitly identified. The site lacks some advanced security headers and explicit privacy/cookie policy pages, which are areas for technical improvement. Overall, the technical infrastructure supports a professional and functional web presence suitable for the company's business needs.

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.
