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

Smart Sender is a technology company offering a SaaS chatbot platform that integrates with multiple popular instant messengers such as Telegram, Viber, WhatsApp, Instagram Direct, Facebook Messenger, Skype, VKontakte, Kik, Line, and WeChat. The platform focuses on automating customer engagement, increasing sales, and improving customer loyalty through chatbots, autoresponders, and automated sales funnels. The website presents a professional and consistent brand image with clear pricing plans and calls to action for free trials and registration. Technically, the website is built using modern JavaScript frameworks, primarily Vue.js, and incorporates common analytics and marketing tools like Google Analytics and Facebook Pixel. The site is mobile-optimized with good SEO practices and a moderate performance profile. Security-wise, HTTPS is enforced, and CSRF tokens are present, but there is room for improvement in implementing additional security headers and publishing explicit security policies. The security posture is solid but could benefit from enhanced transparency around incident response and vulnerability disclosure. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. No direct contact emails or phone numbers are provided, which may limit immediate customer support access but is common for SaaS platforms relying on account portals. Overall, the website and business appear legitimate, professional, and trustworthy with no signs of malicious activity or content safety concerns. Strategic recommendations include enhancing security headers, publishing a security policy, and providing incident response contacts to further strengthen trust and compliance.

Priority findings

5 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"

    • High

      Missing Content-Security-Policy header

      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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Smart Sender operates in the competitive chatbot SaaS market, targeting businesses that want to automate customer communication across multiple messaging platforms. Its multi-channel approach and integration with popular messengers provide a competitive advantage. The business model is subscription-based with free and pro tiers, allowing scalability for small to enterprise clients. The presence of community links and documentation indicates an active user engagement strategy. The company leverages third-party platforms for marketing and analytics but maintains a custom-built website, suggesting technical maturity. No parent or subsidiary companies were identified, indicating an independent operation. The lack of direct contact information on the website suggests a focus on self-service and online account management.

Security posture

The website enforces HTTPS and includes CSRF tokens, indicating attention to basic web security. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces the overall security posture. No explicit security policy or incident response information is published, which is a gap in transparency and readiness. The use of third-party analytics and marketing scripts introduces potential privacy and security risks, though these are industry standard. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is moderate with room for improvement in headers and policy disclosures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  2. Publish a dedicated security policy page detailing security practices, data protection measures, and incident response procedures.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses to improve transparency and trust.
  4. Regularly audit and update third-party scripts and dependencies to minimize vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance with evolving standards.

Technical notes

Notes

The website uses a modern JavaScript framework (Vue.js) for frontend rendering, combined with popular UI libraries like Owl Carousel and FSLightbox for interactive elements. Analytics and marketing integrations include Google Analytics, Google Tag Manager, and Facebook Pixel, enabling user behavior tracking and retargeting. The site is mobile-optimized with responsive images and viewport settings. No CMS was detected, indicating a custom or bespoke platform. Performance appears moderate based on script usage and image assets. The presence of CSRF tokens suggests backend integration with security in mind. Hosting provider details are not explicitly disclosed. Overall, the technical infrastructure is contemporary and suitable for a SaaS platform but could benefit from enhanced security configurations and performance optimizations.
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.
