60/100

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

F-Secure Corporation is a well-established Finnish cybersecurity company with over 35 years of experience and a global user base exceeding 30 million. The company offers a comprehensive suite of cybersecurity products including antivirus, VPN, identity protection, and scam protection, targeting both consumers and service providers. Their business model is subscription-based, emphasizing digital security and privacy. The website is professionally designed, multilingual, and rich in content, reflecting a mature digital presence. Technically, the site uses modern frameworks like Next.js and is hosted on Netlify, with good mobile optimization and SEO practices. However, the current SSL/TLS configuration is invalid or missing, which is a critical security concern that needs immediate remediation. Security headers are properly set, but the lack of valid HTTPS reduces the overall security posture. The site complies with GDPR and provides comprehensive privacy and cookie policies. Overall, the domain registration and WHOIS data align well with the company's identity, supporting high legitimacy and trust. Strategic recommendations include renewing SSL certificates, enabling modern TLS protocols, and enhancing security best practices to improve trust and compliance.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

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

F-Secure holds a strong market position as a trusted cybersecurity provider with a broad product portfolio addressing multiple aspects of digital security and privacy. Their partnerships with major telecom operators like Vodafone, Virgin Media, Swisscom, and Telia enhance their market reach and credibility. The company targets individual consumers, families, and service providers, leveraging subscription revenue streams. Their free tools and educational content support customer engagement and brand loyalty. The website's clear navigation and multilingual support indicate a global strategy. The business model focuses on recurring revenue through software subscriptions, complemented by strategic partnerships and affiliate programs. The company's long history and certifications from AV-TEST reinforce its competitive advantage in the cybersecurity industry.

Security posture

The website demonstrates a moderate security maturity level with proper security headers such as HSTS, X-Content-Type-Options, and X-Frame-Options configured. However, the absence of a valid SSL certificate and disabled TLS protocols represent significant vulnerabilities that could expose users to risks and undermine trust. No evidence of incident response policies or vulnerability disclosure programs was found on the site. The site does not expose sensitive data or show signs of vulnerable libraries. Privacy compliance is strong with clear policies and consent mechanisms. To enhance security posture, immediate action is required to fix SSL/TLS issues and implement OCSP stapling and session resumption. The current security score is moderate but can be significantly improved with these measures.

Recommendations

  1. Renew and properly configure SSL/TLS certificates to enable HTTPS and support modern TLS versions (1.2 and 1.3).
  2. Implement OCSP stapling and session resumption to improve SSL performance and security.
  3. Publish a clear security policy and incident response contact information to enhance transparency and trust.
  4. Establish a vulnerability disclosure program and security.txt file to encourage responsible reporting.
  5. Continue enhancing privacy compliance and user consent mechanisms to maintain GDPR adherence.
Technical notes

Notes

The website is built on a modern React-based framework (Next.js) and hosted on Netlify, indicating a contemporary and scalable infrastructure. The site is well-optimized for mobile devices and accessibility, with good SEO practices including meta tags and Open Graph data. Performance metrics are moderate, with no explicit load time data but efficient resource usage implied by the use of CDN and preloading fonts. The site uses Google Tag Manager and Mixpanel for analytics and marketing, reflecting a mature digital marketing strategy. However, the SSL/TLS configuration is currently invalid or missing, which is a critical technical risk. Addressing this will improve security and user trust. Overall, the technical stack is modern and well-implemented, with room for improvement in security configuration.
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.
