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

Jellyfish.tech is a Ukraine-based full-stack web and mobile development agency established in 2015. The company specializes in customer-centric IT consulting services, focusing on scalable and high-performing digital experiences. Their key services include MVP development, custom web and mobile development, software modernization, product discovery, and EdTech solutions. The agency positions itself as a reliable partner for businesses seeking agile and result-driven software development, leveraging modern technologies such as Python, Django, React, and FastAPI. Technically, the website is built on WordPress and hosted on DigitalOcean, utilizing a modern tech stack with integrations for analytics and marketing tools like Google Analytics, Facebook Pixel, Hotjar, and Calendly. The site is mobile-optimized with good SEO practices and a professional design. However, some accessibility features could be improved. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks DNSSEC and explicit security headers. Forms are protected with Google reCAPTCHA, but there is no published security policy or incident response contact. The WHOIS data is public and consistent with the business profile, indicating a legitimate and stable domain. Overall, Jellyfish.tech demonstrates a solid business and technical foundation with room for improvement in privacy compliance and security best practices. Strategic enhancements in these areas would strengthen trust and regulatory adherence.

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 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. 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

  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

Jellyfish.tech operates in the competitive IT consulting and software development market, targeting businesses that require full-stack web and mobile solutions. Their use of Agile Scrum methodology and focus on MVP development provide a competitive advantage by enabling faster time-to-market and iterative delivery. The company leverages partnerships with technology providers and maintains an active social media presence to enhance brand visibility. Revenue streams likely include project-based consulting and ongoing development services. Growth indicators include recent case studies featuring AI and EdTech projects, signaling adaptation to emerging market trends. The absence of direct contact emails and phone numbers suggests a controlled lead generation approach via contact forms.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and form protection via reCAPTCHA. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents potential vulnerabilities. No incident response or security policy information is publicly available, which may hinder rapid response to security events. Data protection practices are implied but not explicitly documented, indicating a compliance gap with GDPR and related regulations. The use of multiple third-party analytics and marketing tools increases the attack surface and data privacy considerations. Overall, the security posture is adequate for a mid-sized agency but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement and publish comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Develop and make publicly available a security policy and incident response contact information to improve transparency and readiness.
  4. Publish a detailed privacy policy and terms of service to enhance GDPR compliance and user trust.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end leveraging Angular, React, and React Native technologies for development services. Hosting is provided by DigitalOcean, indicating a reliable infrastructure. The site uses multiple external scripts for analytics, marketing, and user engagement, including Google Tag Manager, Facebook Pixel, Hotjar, Calendly, and Mailchimp. Performance is moderate with good mobile optimization and SEO practices. The technical stack supports agile development and continuous integration/delivery pipelines as indicated by case studies. Opportunities exist to reduce technical debt by updating security configurations and improving accessibility 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.
