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

Phaistos is a well-established digital advertising and R&D company based in Greece, operating since 1997. The company specializes in delivering tailored advertising solutions that connect brands with their target audiences across various digital platforms including websites, OTT & TV apps, and DooH sectors. Their market position is strong within the Greek advertising ecosystem, supported by partnerships with numerous agencies and media suppliers. The website reflects a professional and consistent brand image with clear messaging and comprehensive contact information. Technically, the website is built on WordPress with modern integrations such as Google Analytics and reCAPTCHA for security and tracking. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although some improvements in accessibility and security headers could be made. Performance is moderate, with a clean and structured design. From a security perspective, the site uses HTTPS and implements basic security measures like CAPTCHA and cookie consent. However, it lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or suspicious elements were detected. Privacy compliance is addressed with a privacy policy and cookie banner, indicating GDPR awareness. Overall, the website presents a low-risk profile with strong business credibility and a good security posture. Strategic recommendations include enhancing security headers, publishing security policies, and improving accessibility to further strengthen 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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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.

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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

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

Phaistos operates in the media and technology sectors, focusing on digital advertising solutions for agencies, brands, and media suppliers. Their business model revolves around providing innovative ad-tech and tailored advertising campaigns leveraging data-driven insights. The company has a broad partnership ecosystem including major Greek media and advertising agencies, indicating strong market penetration and influence. The presence of multiple office locations and a history dating back to 1997 suggest stability and medium company size. Revenue streams likely include advertising technology services, campaign management, and media supplier partnerships. Growth indicators include expansion into new digital sectors such as DooH and continuous technology evolution. The company’s competitive advantage lies in its R&D focus and strategic innovation combined with data analytics, enabling impactful and engaging advertising campaigns. Their website and branding reinforce a professional and trustworthy image, supporting business development and client acquisition.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and Google reCAPTCHA protecting the contact form against automated abuse. The presence of a cookie consent banner aligns with privacy regulations. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. There is no visible security policy or incident response contact information, which could hinder effective communication in case of security incidents. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses well-maintained WordPress plugins, but regular audits are recommended to mitigate plugin-related risks. Overall, the security posture is good but can be improved by adopting additional security best practices and formalizing incident response procedures.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ email addresses).
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility features to improve compliance and user experience for all visitors.
  5. Conduct regular security audits of WordPress plugins and dependencies to identify and remediate vulnerabilities promptly.

Technical notes

Notes

The website is built on a WordPress CMS platform, leveraging popular plugins such as Contact Form 7 and Google reCAPTCHA for form security. The use of SVG graphics and modern CSS indicates a contemporary design approach. Google Analytics is integrated for visitor tracking and performance monitoring. The site is mobile responsive with good navigation clarity and SEO optimization. Performance is moderate, with potential for improvement through optimization of assets and caching strategies. No critical technical debt or outdated technologies were identified. Hosting provider details are not explicitly available from the HTML content. Overall, the technical infrastructure supports the business needs effectively but could benefit from enhanced security configurations and performance tuning.
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.
