Security report for stackagency.co.uk

Stack Communications Ltd · Other · United Kingdom

High risk. 6 critical or high findings in Network security, SSL/TLS and 2 other checks.

Security score

49/100

Risk levelHigh

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

Stack Communications Ltd appears to be a UK-based communications or agency service provider founded in 2023. The website content is minimal but indicates a professional service offering. However, the domain WHOIS data is unavailable due to a domain registration error indicating the domain name contains too many parts and cannot be registered. This raises concerns about the domain's legitimacy and registration status. Technically, the website uses Bootstrap 3.3.7 and standard web technologies but lacks modern security features such as HTTPS and security headers. No privacy or cookie policies are present, and no contact information or social media links are found, limiting trust and compliance indicators.

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. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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
    • 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

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. GDPR outside view

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

    • 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 · found on this site
  • 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

The company targets business clients seeking communications or agency services in the UK. The business model is service-based, but no detailed services or market positioning information is available. The lack of contact details and domain registration issues may hinder customer trust and business growth. There is no evidence of partnerships or subsidiaries. The website's content and branding are consistent but basic, indicating a small-sized enterprise with limited digital maturity.

Security posture

The security posture is weak due to the absence of HTTPS, security headers, and privacy compliance mechanisms. No incident response or vulnerability disclosure information is available. The domain registration issues further reduce trustworthiness. The website does not appear to use any advanced security frameworks or certifications. There is a risk of data exposure or interception due to lack of encryption and security best practices.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure communications.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance statements.
  3. Add clear contact information including company emails and phone numbers.
  4. Configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Resolve domain registration issues or migrate to a properly registered domain.

Technical notes

Notes

The website uses Bootstrap 3.3.7 and standard HTML5 and CSS3 technologies. The site appears moderately optimized for performance and mobile devices but lacks advanced SEO and accessibility features. No CMS or hosting provider information is detected. The absence of analytics or tracking scripts suggests minimal data collection. The technical infrastructure is basic and could benefit from modernization and security enhancements.
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.
