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

AOTsend operates as a specialized Managed Email API provider focusing on transactional email services such as OTP, 2FA, verification, and notification emails. The company positions itself as a cost-effective and reliable alternative to larger providers like Amazon SES, emphasizing high delivery and inbox rates, secure API-based sending, and anti-spam mechanisms. The website demonstrates a mature technical infrastructure using modern frontend frameworks and analytics tools, though lacks some advanced security headers and explicit privacy compliance mechanisms. Security posture is moderate with strengths in email content review and IP reputation management but could improve with enhanced headers and incident response transparency. Overall, the business appears legitimate and professional, though the absence of WHOIS data introduces some uncertainty. Strategic recommendations include improving security headers, privacy compliance, and publishing security policies to enhance 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

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 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. GDPR outside view

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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

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

AOTsend targets developers and businesses requiring transactional email APIs, offering a SaaS model with pay-per-use pricing at $0.28 per 1000 emails. Its niche focus on triggered transactional emails differentiates it from broader email providers. The company leverages dedicated IP pools and multi-IP rotation to maintain high delivery rates and IP reputation. Customer testimonials and detailed documentation support credibility. The partnership ecosystem includes related email API and brand service providers. The business model is lean, technology-driven, and focused on stable, secure email delivery with global reach. Growth indicators include comprehensive API documentation, multi-language code examples, and active customer support via Telegram.

Security posture

The website enforces HTTPS and employs anti-spam and email content review mechanisms to protect email sending integrity. However, the lack of visible security headers such as CSP, HSTS, and X-Frame-Options reduces overall security robustness. No explicit incident response or vulnerability disclosure policies are published, limiting transparency. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism detected. The absence of WHOIS registrant data reduces trust slightly. Overall, security maturity is moderate with room for improvement in web security best practices and compliance documentation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  3. Publish a formal security policy and incident response contact information to improve transparency and trust.
  4. Consider creating a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and conduct audits to improve compliance and user experience.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap 5, Font Awesome, Feather Icons, jQuery, and AOS for animations. Analytics are implemented via Google Analytics and Baidu Analytics. The site is mobile responsive and well-structured with clear navigation and comprehensive content. However, no CMS or hosting provider information is evident. Performance is moderate with no major issues detected. The absence of advanced security headers and cookie consent mechanisms indicates technical debt in security and privacy compliance. The WHOIS data is missing, which may indicate privacy protection or recent registration, representing a potential risk factor. Overall, the technical infrastructure supports the business model but requires enhancements in security and compliance.
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.
