Their market position is that of a specialized provider offering cloud-hosted, scalable web solutions primarily targeting businesses, entrepreneurs, e-commerce projects, agencies, and specialists.

Technically, the website leverages modern technologies including Bootstrap, Google Tag Manager, Hotjar, and is hosted on Amazon Web Services, ensuring good performance and mobile optimization. Security posture is solid with HTTPS and multi-factor authentication mentioned, though explicit security headers and incident response policies are not publicly documented.

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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

  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

OptimWeb operates in the technology and e-commerce sectors, providing custom web and e-shop development services. Their business model focuses on tailored solutions with cloud infrastructure, targeting SMEs and startups in the Czech Republic. The company leverages partnerships with clients and agencies, emphasizing flexibility and long-term collaboration. Revenue streams likely include project-based development and ongoing maintenance. The presence of client testimonials and references indicates a solid reputation and customer satisfaction. The company maintains a professional online presence with clear navigation and comprehensive service offerings. However, the lack of publicly available WHOIS data may warrant further verification for business due diligence. No evidence of subsidiaries or parent companies was found.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, DNSSEC mentioned as standard, and multi-factor authentication for user access. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, no explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), or X-Frame-Options were detected, which are recommended to enhance protection against common web attacks. There is no publicly available security policy or incident response contact information, which could improve transparency and readiness. No vulnerabilities or exposed sensitive data were identified in the analysis. The use of third-party analytics and tracking tools like Google Analytics and Hotjar is balanced with privacy controls. Overall, the security posture is good but could be strengthened by adopting additional HTTP security headers and publishing security policies.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and tracking tools to ensure they do not introduce security or privacy risks.
  5. Verify and publish domain WHOIS information to enhance domain transparency and business credibility.

Technical notes

Notes

The website is built using modern web technologies including Bootstrap for responsive design, Google Fonts for typography, and JavaScript libraries for analytics and user behavior tracking (Google Tag Manager, Hotjar). Hosting is provided by Amazon Web Services, ensuring scalability and reliability. The site demonstrates fast loading times, mobile optimization, and good SEO practices with proper meta tags and structured data (JSON-LD). The CMS appears custom-built, tailored to client needs. There is no evidence of technical debt or outdated libraries. Opportunities exist to improve security headers and formalize security policies. Overall, the technical infrastructure supports a professional and performant web presence aligned with business goals.
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.
