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

ISG - International Service Group is a well-established HR consulting company founded in 1999, specializing in recruiting, executive search, training, and personnel management services. With over 800 employees and more than 60 offices worldwide, ISG holds a strong market position as a leading personnel consulting provider in Europe and beyond. Their business model focuses on delivering tailored HR solutions across multiple industries including automotive, finance, technology, and healthcare. The website content is professionally presented, targeting businesses seeking comprehensive HR services internationally. Technically, the website is built on WordPress with modern plugins such as Gravity Forms and uses LiteSpeed Cache for performance optimization. However, the site currently lacks a valid SSL certificate and does not support modern TLS protocols, which significantly impacts its security posture. The site includes a cookie consent mechanism and privacy policy, indicating awareness of privacy compliance, but lacks explicit security or incident response policies. From a security perspective, the absence of HTTPS and modern encryption protocols is a critical vulnerability that exposes users to risks. While some security headers like HSTS are present, the overall SSL/TLS configuration is poor. There are no detected vulnerabilities related to common exploits, but the lack of encryption is a major concern. WHOIS data confirms the legitimacy and consistency of the domain registration with the business claims. Overall, ISG's website demonstrates strong business credibility and content quality but requires urgent security improvements to protect user data and enhance trust. Strategic recommendations include immediate installation of a valid SSL certificate, enabling modern TLS protocols, and implementing additional security headers and policies to improve the security posture 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

6 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

ISG operates in the HR consulting sector with a diversified service portfolio including recruiting, executive search, training, media services, and temporary staffing. Their extensive international footprint with offices in over 45 countries supports a global client base. The company leverages a professional digital presence with multilingual support and targeted job listings, indicating a mature business model focused on B2B services. Their competitive advantage lies in their broad industry expertise and international network. The website content and social media presence reinforce their market positioning as a trusted HR partner. Revenue streams likely include consulting fees, placement fees, training programs, and media advertising services. The company shows growth potential through sustainability consulting (ISG Green) and digital transformation of HR services.

Security posture

The current security maturity level is low due to the absence of a valid SSL certificate and lack of HTTPS support, which is a critical vulnerability. The server uses nginx but does not enable any TLS protocols or strong cipher suites, exposing the site to potential interception and data compromise. Security headers are minimal, with only HSTS present. The site uses Google reCAPTCHA on forms, which helps mitigate spam but does not compensate for the lack of encryption. No explicit incident response or security policies are published, indicating limited transparency in security governance. Compliance with GDPR is partially demonstrated through privacy and cookie policies, but security controls need significant enhancement to meet best practices and regulatory expectations.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site immediately.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and configure strong cipher suites to secure communications.
  3. Implement additional security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
  4. Publish a clear security policy and incident response plan accessible to users and partners.
  5. Regularly audit and update server and application security configurations to address emerging threats and compliance requirements.

Technical notes

Notes

The website is powered by WordPress 6.8.1 with the Gravity Forms plugin for form management and LiteSpeed Cache for performance optimization. The server runs nginx 1.22.1 and DNS is managed by PixelX name servers. The site uses jQuery and custom JavaScript for UI interactions and lazy loading of images. Despite modern CMS and caching technologies, the lack of SSL/TLS support severely impacts security and trust. Performance metrics are not available, but caching and lazy loading indicate efforts to optimize speed. The site is multilingual with hreflang tags for multiple languages, enhancing SEO and user experience. Accessibility is basic with some ARIA labels and semantic HTML. SEO is supported by meta tags, Open Graph, and JSON-LD structured data for rich snippets.
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.
