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

Invoice Ninja is a mature SaaS platform providing free and paid invoicing software tailored for small businesses, freelancers, and service professionals. The company offers a comprehensive suite of tools including invoicing, expense tracking, project management, payment gateways, and automation integrations. The website is professionally designed with consistent branding and clear navigation, supporting multiple languages and platforms including web and mobile apps. Technically, the site is built on WordPress with Elementor and uses Cloudflare DNS for performance and security. Security posture is good with HTTPS and domain management best practices, though explicit security headers and policies are not evident. Privacy compliance is weak due to missing privacy and cookie policies and lack of consent mechanisms. Overall, the domain WHOIS data supports legitimacy with a long registration history and no privacy protection. Strategic improvements in privacy compliance and security transparency would 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

7 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

    • 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

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

Invoice Ninja positions itself strongly in the invoicing software market, competing with established players like Zoho, Freshbooks, and Invoice2Go. Its business model is SaaS with a freemium approach, offering free invoicing software with paid upgrades and additional features. The target audience includes freelancers, small business owners, and service professionals seeking efficient billing and project management tools. The company maintains a referral program and provides product demos to attract users. Partnerships with related service providers like event scheduling and demo platforms indicate a growing ecosystem. The company has been operational since 2013, indicating stability and market experience.

Security posture

The website enforces HTTPS and uses domain status locks to prevent unauthorized changes, reflecting good domain security practices. However, the absence of DNSSEC and missing security headers such as Content Security Policy, HSTS, and X-Frame-Options reduce the overall security posture. No explicit security or incident response policies are published on the site, and no vulnerability disclosure or security.txt files are found. The site uses Google Analytics for tracking without visible cookie consent, which may pose privacy compliance risks. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security maturity is moderate but could be improved with enhanced headers and transparency.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR compliance.
  3. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  4. Publish a security policy and incident response plan on the website, including contact channels for security issues (e.g., security@ or abuse@ emails).
  5. Introduce a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting and improve security culture.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor page builder and Rank Math SEO plugin, indicating a contemporary and SEO-optimized infrastructure. The tech stack includes JavaScript and jQuery libraries, with assets loaded from the site and trusted external sources like YouTube and Cloudflare. Hosting and domain registration are managed by reputable providers (GoDaddy and Cloudflare). Performance is moderate with good mobile optimization and accessibility basics. The site supports multiple languages and includes structured data (JSON-LD) for SEO and social media integration. Technical risks include missing DNSSEC and lack of advanced security headers, which could be addressed to reduce attack surface and improve resilience.
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.
