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

ProfiSMS is a Czech-based telecommunications company specializing in SMS marketing and customer communication platforms. With a strong market presence and a claim of 18 years in operation, it offers a comprehensive suite of messaging services including bulk SMS, 2-way SMS, SMS Voice, and Viber messaging. The company targets businesses and developers seeking efficient and reliable communication channels, supported by extensive API integrations and professional tools. The website reflects a mature digital presence with excellent content quality, clear navigation, and mobile optimization. Technically, the site employs modern technologies such as Google Tag Manager, reCAPTCHA, and Chatwoot for live chat support, indicating a well-maintained infrastructure. Security practices are evident in the use of HTTPS, end-to-end encryption claims, and a detailed cookie consent mechanism, although explicit security policies and incident response contacts are not publicly available. The absence of WHOIS data is a minor concern but does not significantly detract from the overall legitimacy given the professional presentation and business references. Strategic recommendations include enhancing transparency around security policies and improving HTTP security headers to further strengthen 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.

Priority findings

9 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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
    • High

      Missing Content-Security-Policy 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

ProfiSMS holds a leading position as the largest SMS aggregator in the Czech Republic, supported by partnerships with major operators and GSMA-certified SMS hubs. Its business model is B2B SaaS with tiered pricing based on SMS volume, supplemented by additional professional services such as text identifiers and unsubscribe management. The company benefits from a parent company, Vercom, which likely provides additional resources and market reach. Client testimonials from reputable companies reinforce its market credibility. The platform's integration capabilities with popular systems like Salesforce and Bloomreach indicate a strategic focus on seamless automation and developer adoption. Growth indicators include a high volume of monthly messages and a broad service portfolio. The company’s marketing and analytics tools are well integrated, balancing effective user tracking with privacy compliance.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and end-to-end encryption for messaging services. The cookie consent mechanism is comprehensive, allowing granular user control and compliance with GDPR. However, the lack of visible HTTP security headers such as CSP, HSTS, and X-Frame-Options suggests room for improvement. No explicit security policy or incident response information is published, which could hinder transparency and user trust. The use of reputable third-party services like Google reCAPTCHA and Chatwoot enhances security and user interaction safety. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security maturity is good but could be elevated by publishing formal security documentation and implementing additional HTTP headers.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and verify HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance WHOIS transparency or provide domain registration details to improve trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager for analytics and marketing, Google reCAPTCHA for bot protection, and Chatwoot for live chat support. The frontend is built with responsive design principles, likely leveraging Bootstrap or similar frameworks for layout and navigation. Performance appears optimized with asynchronous script loading and preconnect hints for fonts. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data describing the organization. Accessibility features are present but could be further enhanced with ARIA roles and landmarks. Hosting details are not explicitly identified, but the use of HTTPS and CDN resources suggests a professional hosting environment. Overall, the technical implementation supports a fast, secure, and user-friendly experience with opportunities for incremental improvements in security headers and accessibility.
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.
