Rafinerija ulja Modriča, operated by OPTIMA Grupa d.o.o., is a medium-sized regional manufacturer specializing in motor oils, lubricants, base oils, paraffins, and specialized products for extreme conditions. Established in 2022, the company holds a strong market position as the largest regional producer with distribution across more than 22 international markets. Their business model focuses on manufacturing, toll blending, and private label services, targeting automotive and industrial sectors. The website reflects a professional digital presence with clear branding, product information, and multiple contact channels. Technically, the site is built on WordPress with modern libraries and SEO optimizations, hosted via GoDaddy with DNS on european-server.com.

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.
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.
Critical
Unable to retrieve SSL certificate
Could not establish secure connection to retrieve certificate information
What to do: Check if the server is accessible and SSL/TLS is properly configured
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"

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.

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.

Business context
Business profile
The company leverages its long-standing tradition and modern blending technology to offer over 250 products, including motor oils, base oils, paraffins, and specialized lubricants for harsh environments. Their strategic location in Europe facilitates efficient market access. The partnership with OPTIMA Grupa d.o.o. enhances their operational capabilities. The website's content and social media presence indicate active engagement with customers and stakeholders. Revenue streams likely include direct product sales, toll blending contracts, and private label manufacturing. Growth indicators include recent domain registration and expanding product portfolio. The company maintains a professional image with consistent branding and trust signals such as certifications and approvals from major automotive manufacturers.
Security posture
The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. No DNSSEC is enabled, which is a potential security enhancement area. The absence of explicit security headers like Content-Security-Policy or X-Frame-Options reduces defense-in-depth. The use of Gravity Forms with validation and no visible exposed credentials indicates good input handling. No known vulnerabilities or malware indicators were detected. However, the lack of published security policies or incident response contacts suggests limited transparency in security governance. Overall, the security posture is moderate to good but could benefit from enhanced headers, DNSSEC, and published security documentation.
Recommendations
Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
Publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and enhance user trust.
Add explicit security and incident response policies on the website, including contact channels for security issues.
Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
Automated reading of the public site. Ratings are indicative.

Technical notes
Notes
The website is built on WordPress CMS using a custom theme 'rafinerija-ulja-modrica' and integrates several modern JavaScript libraries including jQuery, GSAP, Swiper.js, and Lightbox PhotoSwipe for enhanced UI/UX. SEO is managed via Yoast SEO plugin with proper meta tags and structured data (JSON-LD) for improved search engine visibility. Hosting is provided through GoDaddy with DNS servers at european-server.com. Performance is moderate with asynchronous script loading and preconnect hints. Mobile optimization is good with responsive design and viewport meta tags. Accessibility is basic with some ARIA attributes and a11y speak regions. Overall, the technical infrastructure is modern and well maintained but could improve accessibility and 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.
