Security report for arcus.uk.com

Arcus Consulting LLP · Construction & Property Consulting · United Kingdom

High risk. 9 critical or high findings in GDPR outside view, SSL/TLS and 2 other checks.

Security score

47/100

Risk levelHigh

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

The website's security posture is critically weak, exposing the business to significant risks including data breaches, regulatory non-compliance, and reputational damage. The absence of HTTPS encryption is a fundamental flaw impacting data confidentiality and trustworthiness. Key security headers are missing, increasing susceptibility to common web attacks such as clickjacking, content injection, and cross-site scripting. GDPR compliance is severely lacking, with no privacy policy or cookie consent mechanisms, risking legal penalties and loss of customer trust. The lack of an information security framework, incident response, and business continuity planning indicates unpreparedness for cyber incidents. Email security measures like DMARC and DKIM are insufficient, raising the risk of phishing and spoofing attacks. Exposure of high-risk services like FTP further amplifies vulnerability to unauthorized access. Immediate remediation is essential to protect sensitive data, maintain regulatory compliance, and safeguard the business’s reputation.

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

9 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

  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 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';…

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.

Technical notes

Notes

The most critical findings include the complete lack of HTTPS encryption (SSL/TLS), which exposes all data exchanges to interception and man-in-the-middle attacks. Missing security headers like Strict-Transport-Security, X-Frame-Options, and Content-Security-Policy leave the site vulnerable to clickjacking, MIME-type sniffing, and cross-site scripting attacks. GDPR-related deficiencies, including absent privacy policies and cookie consent, expose the organization to regulatory fines. The absence of an information security framework, security policies, incident response, and business continuity plans highlights gaps in governance and incident preparedness. Email security weaknesses such as non-enforcing DMARC and missing DKIM records increase phishing risks. Additionally, the presence of an unsecured FTP service is a critical network security risk, potentially allowing unauthorized data access or modification.
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.
