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

Serco Comercial S.A. de C.V. is a Mexican commercial and manufacturing company specializing in products that improve food safety, liquid and air filtration, and laboratory equipment. With over 30 years of market presence, it serves a broad range of clients from small businesses to multinational corporations across Mexico. The company offers a comprehensive portfolio including inocuity testing products, filtration solutions, disinfectants, laboratory materials, and specialized software, complemented by training and advisory services. Their market position is strong within the manufacturing and industrial sectors, supported by recognized clients and consistent branding. Technically, the website employs multiple versions of Bootstrap and an outdated jQuery library, which may affect performance and security. The site is moderately optimized for mobile and accessibility, with basic SEO practices. The presence of Olark live chat enhances customer engagement. However, the lack of modern security headers and cookie consent mechanisms indicates room for improvement in compliance and security posture. From a security perspective, the site uses HTTPS but lacks visible security headers and uses outdated JavaScript libraries, posing potential vulnerabilities. No incident response or security policies are publicly disclosed. Privacy policy exists but is basic and externally hosted. Contact information is clearly presented, enhancing trust. No signs of blocking or WAF interference were detected, allowing full content access. Overall, the website is professional and trustworthy but would benefit from technical modernization, enhanced security practices, and improved privacy compliance to reduce risk and strengthen 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

9 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

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

Serco Comercial operates in the manufacturing and commercial sector focused on food safety and filtration products. Their competitive advantage lies in their 30-year history, broad product range, and service offerings including training and technical support. The business model combines product sales with value-added services, targeting industrial clients in food, pharmaceutical, cosmetic, and nutraceutical industries. The company maintains partnerships with recognized brands and has a visible client portfolio featuring major Mexican companies. Growth indicators include diversified product lines and digital presence with multiple related domains. Strategic observations suggest opportunities in enhancing digital security and compliance to align with evolving regulatory requirements and customer expectations.

Security posture

The current security maturity level is moderate with HTTPS enabled but lacking critical security headers such as Content Security Policy, HSTS, and X-Frame-Options. The use of an outdated jQuery version introduces potential vulnerabilities. No public incident response or security policies are found, indicating limited transparency in security governance. Privacy compliance is minimal with no cookie consent mechanism and a basic privacy policy. The absence of a vulnerability disclosure program or security.txt file reduces the ability to manage security incidents proactively. Overall, the security culture appears functional but could be significantly improved by adopting modern best practices and compliance frameworks.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Develop and publish detailed privacy and cookie policies with explicit consent mechanisms to improve GDPR and local compliance.
  4. Establish a formal incident response process and publish contact channels for security issues (e.g., security@ or abuse@ emails).
  5. Consolidate CSS frameworks to a single modern Bootstrap version to improve site performance and maintainability.

Technical notes

Notes

The website uses a combination of Bootstrap versions 3, 4, and 5, which may cause CSS and JavaScript conflicts affecting user experience and maintainability. jQuery 1.4 is outdated and poses security risks. The site loads CSS and JS from reputable CDNs, improving availability. Mobile optimization is basic but functional. SEO metadata is present but could be enhanced with structured data (none detected). No CMS is detected, indicating a custom or static site. Hosting provider details are not available from the provided data. Performance is moderate, with potential improvements by streamlining resources and updating libraries. Accessibility features are minimal but present. Overall, the technical infrastructure is functional but requires modernization to meet current web standards and security expectations.
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.
