ShortPixel is a well-established technology company specializing in image optimization services primarily targeting WordPress users and website owners seeking to improve site speed and SEO through advanced image compression and format conversion technologies. The company offers SaaS products including WordPress plugins and CDN-based adaptive image delivery, positioning itself as a leader in the web performance optimization niche. The website demonstrates a mature digital presence with comprehensive content, customer testimonials, and clear product offerings. Technically, the website employs modern frameworks such as Bootstrap and JavaScript libraries like Tippy.js and Popper.js, leveraging Cloudflare for DNS and CDN services to ensure fast performance and global reach. Analytics and marketing tools like Google Analytics, Google Tag Manager, and ProfitWell are integrated for user tracking and subscription management. The site is mobile-optimized and SEO-friendly, with proper meta tags and structured content. From a security perspective, the site uses HTTPS with a valid SSL configuration and domain transfer protection. However, DNSSEC is not enabled, and no explicit security policies or incident response contacts are publicly disclosed. No vulnerabilities or exposed sensitive data were detected in the content.

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

3 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

  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

ShortPixel operates in the competitive image optimization market, focusing on WordPress users and web developers. Its competitive advantages include proprietary SmartCompress technology, support for next-gen image formats (WebP, AVIF), and seamless integration via plugins and CDN services. The business model is subscription-based SaaS with additional revenue from plugin downloads and usage credits. The company has a medium-sized footprint with a founding date in 2014, indicating stability and experience. The presence of extensive customer testimonials and positive reviews highlights strong customer satisfaction and support quality. The ecosystem includes partnerships with WordPress and CDN providers, enhancing market reach.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and domain transfer protection. The use of Cloudflare DNS and CDN adds resilience and DDoS mitigation capabilities. However, the absence of DNSSEC and lack of published security policies or incident response contacts represent areas for improvement. No signs of exposed credentials, malware, or phishing were found. Privacy compliance is well addressed with clear cookie and privacy policies and consent mechanisms. The security posture is good but could be enhanced by adopting additional security headers and transparency around incident response.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Implement additional HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  4. Consider providing direct company contact information for support and security inquiries.
  5. Maintain and regularly audit third-party scripts and analytics tools to minimize tracking risks.

Technical notes

Notes

The website uses a modern and robust technical stack including Bootstrap for responsive design, JavaScript libraries for enhanced UI interactions, and Cloudflare for DNS and CDN services ensuring fast global delivery. The site is well-optimized for mobile devices and SEO, with comprehensive meta tags and Open Graph data. Analytics and marketing tools are integrated for user behavior tracking and subscription management. Performance is fast with optimized images and lazy loading techniques. Technical debt appears low, but enabling DNSSEC and improving security headers would further modernize the infrastructure.
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.
