69/100

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

Måns Gullberg operates as an SEO expert and entrepreneur primarily through his company Modifinder AB, founded in 2013. The business focuses on providing affordable and quality search engine optimization services to Swedish companies, with a strong track record of success and client satisfaction. The website presents a professional image with clear business information, social media presence, and published SEO-related content, positioning the company as a credible player in the Swedish SEO market. Technically, the website is built on a modern stack including HTML5, CSS3, and JavaScript, with integration of Google Analytics and Tag Manager for tracking. The site is mobile optimized and accessible, with good SEO practices implemented. Security-wise, HTTPS is enforced, but the site lacks advanced security headers and published security policies. The absence of privacy and cookie policies is a notable compliance gap. The WHOIS data for the domain is missing, which raises concerns about domain registration legitimacy despite the professional website content. Overall, the site scores well on content and technical implementation but needs improvements in privacy compliance and domain registration transparency.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Modifinder AB is a small-sized SEO agency targeting Swedish businesses seeking to improve their Google search rankings. The company leverages over a decade of experience and partnerships, such as with TodaysWeb, to deliver effective SEO solutions. The business model centers on service delivery in SEO consulting and internet marketing. The website content and external references indicate a stable market position with a loyal client base. The company maintains active social media profiles and publishes SEO-related interviews and articles, enhancing its industry credibility. However, the lack of company domain email and physical address on the website may limit trust for some clients. The partnership ecosystem includes TodaysWeb, contributing to the company's success. Growth indicators include a decade-long operation and hundreds of client successes.

Security posture

The website enforces HTTPS and uses reputable analytics and tracking tools. However, it lacks critical security headers such as Content-Security-Policy and Strict-Transport-Security, which could improve protection against common web attacks. No forms collect sensitive data, reducing risk exposure. There is no published privacy policy, cookie policy, or security incident contact information, which are important for GDPR compliance and incident response readiness. The absence of WHOIS data for the domain is a significant anomaly that impacts trustworthiness. Overall, the security posture is moderate but requires enhancements in policy transparency and technical security controls to meet best practices and regulatory requirements.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance site security.
  3. Add a security.txt file or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Use a company domain email address for contact information to improve business credibility and trust.
  5. Investigate and resolve the missing WHOIS data issue to ensure domain registration transparency and legitimacy.

Technical notes

Notes

The website is built using modern web standards with clean HTML5 and CSS3, and enhanced by JavaScript for interactivity and tracking. It uses the N.nu CMS platform. Google Analytics and Google Tag Manager are integrated for visitor analytics, supplemented by Redistats tracking. The site is mobile responsive and accessible with good SEO meta tags and structured data (JSON-LD) describing the person and organization. Performance is moderate, with no major issues detected. However, the hosting provider is not explicitly identified. The site lacks advanced security headers and privacy compliance mechanisms, which are technical debt areas to address. Overall, the technical infrastructure supports a professional and user-friendly experience but can be improved for security and compliance.
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.
