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

NESTRO PETROL a.d. operates the largest network of petrol stations in Bosnia and Herzegovina, managing over 80 retail locations under the NESTRO brand. The company offers various loyalty card programs targeting both individual and corporate customers, enhancing customer retention and engagement. The website reflects a mature business with a clear market position supported by its parent company OPTIMA Grupa d.o.o. The digital presence includes interactive maps, promotions, and news updates, catering to a general audience primarily in the Serbian language with options for Russian and English. Technically, the website utilizes a traditional tech stack including jQuery 1.11.1, Bootstrap, and Google Analytics for tracking, alongside Raygun for error monitoring. While the site is mobile optimized and well-structured, some technical debt is evident due to the use of outdated libraries and lack of modern security headers. The absence of DNSSEC and security policies indicates room for improvement in security posture. Security-wise, the domain is well-established with a consistent WHOIS record and clientTransferProhibited status, indicating domain ownership protection. However, the lack of DNSSEC, security headers, and outdated JavaScript libraries present potential vulnerabilities. No explicit privacy or cookie policies were found, which may impact GDPR compliance. The site does not appear to be blocked or protected by a WAF, allowing full content access. Overall, the website is professional and functional with moderate security and privacy compliance. Strategic improvements in security headers, updated libraries, and explicit privacy documentation would enhance trust and compliance. The business is credible with a strong market presence but should address technical and compliance gaps to reduce risk and improve user trust.

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

8 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"

      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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

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

NESTRO PETROL holds a dominant position in the Bosnian fuel retail market, leveraging a large network of stations and loyalty programs to maintain customer loyalty. The business model focuses on retail fuel sales supplemented by value-added services such as corporate cards and family-oriented loyalty cards. The company benefits from its affiliation with OPTIMA Grupa, which provides a broader industrial and commercial ecosystem. Partnerships with regional refineries and international entities like Zarubezhneft further strengthen its supply chain and market reach. The website's multilingual support and digital tools indicate a customer-centric approach aimed at broad demographic segments. Growth indicators include active promotions, news updates, and mobile app offerings. The partnership ecosystem is well integrated, supporting operational and marketing efforts.

Security posture

The current security posture is moderate but has notable gaps. The domain registration is transparent and consistent with business claims, which is positive. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces protection against DNS spoofing and clickjacking attacks. The use of an outdated jQuery version (1.11.1) exposes the site to known vulnerabilities that could be exploited. No explicit incident response or security policy pages were found, limiting transparency on how security incidents are handled. The lack of cookie consent mechanisms and privacy policies also indicates potential GDPR compliance issues. The site uses HTTPS as implied by external scripts but no direct SSL configuration details were provided. Overall, the site would benefit from modern security best practices and compliance documentation to improve its security maturity and reduce risk.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Upgrade jQuery and other JavaScript libraries to supported, secure versions to mitigate known vulnerabilities.
  4. Publish clear privacy and cookie policies along with a consent mechanism to improve GDPR compliance.
  5. Develop and publish an incident response policy and provide dedicated security contact channels to enhance transparency and readiness.

Technical notes

Notes

The website is built on a traditional web stack using Bootstrap for responsive design and jQuery 1.11.1 for client-side scripting. Google Analytics and Google Tag Manager are used for user tracking and analytics, while Raygun provides error monitoring. The site is mobile optimized with a clear navigation structure and interactive elements such as carousels and maps. However, the use of an outdated jQuery version indicates technical debt and potential security risks. No modern CMS or frameworks like React or Angular are detected, suggesting a custom or legacy CMS. Performance is moderate with no explicit indicators of optimization or CDN usage. Accessibility features are basic, and SEO optimization is minimal with no structured data or Open Graph tags detected. Overall, the technical infrastructure supports the business needs but requires modernization and security enhancements.
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.
