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

Byter Ltd is a London-based digital marketing and social media agency offering a comprehensive range of services including SEO, social media management, advertising, content creation, influencer marketing, web development, and email marketing. The company targets businesses seeking to enhance their digital presence and marketing effectiveness. The website reflects a professional and consistent brand image with good content quality and clear navigation, supporting its market position as a specialized agency in the hospitality and broader digital marketing sectors. Technically, the website is built on WordPress with modern tools such as WPBakery Page Builder and Yoast SEO Premium. It integrates multiple analytics and marketing technologies including Google Analytics, Facebook Pixel, HubSpot, and others, demonstrating a mature digital infrastructure. Hosting is provided by Hostinger, a reputable provider, and the domain is well-registered with a long history. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks DNSSEC and explicit security headers. There is no visible security policy or incident response information, which could be improved. Privacy compliance is partial; while a cookie consent mechanism is present, explicit privacy and cookie policy pages were not found in the provided data. The extensive use of tracking technologies suggests a need for clear privacy disclosures. Overall, the website is professional and trustworthy with a solid business foundation. Strategic improvements in privacy policy publication, security headers, and DNS security would enhance its security posture and compliance standing.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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

Byter Ltd operates as a small digital marketing agency focused on delivering a wide array of services to businesses, particularly in hospitality and related sectors. Its competitive advantage lies in the breadth of services from SEO to influencer marketing and web development, supported by integrations with leading marketing platforms. The business model is service-oriented, generating revenue through client engagements. The company demonstrates growth potential through digital maturity and marketing tool adoption. Partnerships with platforms like HubSpot and Mailchimp indicate a strong ecosystem. The website content and structure support a professional image, aiding customer acquisition and retention.

Security posture

The security posture of Byter Ltd's website is moderate. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. The lack of published security policies and incident response contacts indicates limited transparency and preparedness for security incidents. The extensive use of third-party tracking scripts necessitates vigilant management to avoid vulnerabilities. No critical vulnerabilities or exposed sensitive data were detected. Enhancing security headers, enabling DNSSEC, and publishing security policies would significantly improve the security maturity.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Publish a comprehensive privacy policy and cookie policy pages clearly accessible from the website footer or header.
  4. Establish and publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update third-party scripts and plugins to minimize vulnerabilities and ensure compliance with privacy regulations.

Technical notes

Notes

The website is built on a WordPress CMS platform using WPBakery Page Builder and Yoast SEO Premium for content management and SEO optimization. It employs a modern tech stack including jQuery and integrates multiple analytics and marketing tools such as Google Analytics, Facebook Pixel, HubSpot, and others. Hosting is provided by Hostinger, a reputable provider. The site shows good mobile optimization and moderate performance. Accessibility features are basic but present. The technical implementation supports a professional and functional website 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.
