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

3 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.

    • 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

    • 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

  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

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.
  • 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

Persollo operates in the influencer marketing technology sector, leveraging AI and machine learning to provide brands and agencies with actionable insights and sales tools. Its competitive advantage lies in combining deep analytics with instant checkout functionality, reducing friction in social commerce. The business model is SaaS-based, targeting small to medium-sized enterprises and marketing professionals. The company maintains partnerships with related services such as HeyLink.me for link management, enhancing its ecosystem. Growth indicators include a well-maintained domain since 2014, active social media presence, and a portfolio of case studies and blog content. The platform's focus on transparency, audience quality scoring, and brand safety aligns with market demand for trustworthy influencer marketing solutions.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and use of reputable third-party services like Stripe for payment processing. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No explicit incident response or security policy pages were found, which could impact trust and compliance. The site does not expose sensitive data in its HTML and uses secure forms for data collection. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected, which may pose GDPR compliance risks. Overall, the security posture is moderate to good but would benefit from enhanced security controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  4. Publish an explicit security policy and incident response contact information to enhance transparency and trust.
  5. Regularly audit third-party libraries and dependencies to ensure no vulnerable components are used.

Technical notes

Notes

The website is built using modern front-end technologies including React and Semantic UI, ensuring a responsive and interactive user experience. Hosting on DigitalOcean with Cloudfront CDN provides fast content delivery and scalability. Integration with Stripe enables secure payment processing. The site includes tracking pixels from Facebook and Twitter for marketing analytics. Performance is optimized with preloading of critical CSS and asynchronous loading of scripts. Accessibility and SEO are addressed with proper meta tags, Open Graph data, and mobile optimization. Technical debt appears low, but security enhancements and privacy compliance improvements are recommended to reduce risk and improve user trust.
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.
