Sleekplan is a technology company founded in 2020 that offers an all-in-one user feedback tool designed to help businesses collect, discuss, and prioritize customer feedback. Their platform integrates feedback boards, public roadmaps, changelogs, and satisfaction surveys (CSAT and NPS) to streamline product management and customer engagement. Positioned as a competitive SaaS solution, Sleekplan targets businesses and product teams seeking to enhance their feedback loops and product development transparency. The website demonstrates a professional and consistent brand presence with excellent content quality and user experience. Technically, Sleekplan employs a modern technology stack including Vue.js for frontend development, integrates analytics tools like Google Analytics and PostHog for user behavior tracking, and uses AWS for hosting infrastructure. The site is well-optimized for performance, mobile responsiveness, and SEO, with clear navigation and accessibility considerations. Cookie consent and privacy compliance mechanisms are implemented effectively, reflecting good digital maturity. From a security perspective, the website enforces HTTPS, uses clientTransferProhibited domain status, and anonymizes IP addresses in analytics. However, DNSSEC is not enabled, and explicit security headers are not evident, suggesting room for improvement. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns with the business claims, showing a consistent and legitimate domain registration. Overall, Sleekplan presents a low-risk profile with a strong security posture and compliance awareness. Strategic recommendations include enabling DNSSEC, publishing a vulnerability disclosure policy, enhancing security headers, and providing incident response contact details to further strengthen trust and security posture.

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

4 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 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

    • High

      Weak DKIM Key

      DKIM selector 'google' uses 1016-bit key

      What to do: Use at least 2048-bit RSA keys for DKIM

  3. 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

  • 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

Sleekplan operates in the competitive user feedback and product management SaaS market, offering a comprehensive platform that covers the entire feedback lifecycle from collection to roadmap sharing and satisfaction measurement. Their business model is subscription-based with a free trial, targeting small to medium-sized businesses and product teams. The company leverages integrations with popular tools like Intercom, Jira, Slack, and GitHub to embed itself into existing workflows, enhancing customer stickiness. Positive customer testimonials and high ratings on platforms like G2 and Capterra indicate strong market acceptance and user satisfaction. The presence of an affiliate program suggests active marketing and growth strategies. The company appears focused on transparency and user engagement, which are key competitive advantages in this sector.

Security posture

Sleekplan demonstrates a mature security posture with HTTPS enforced site-wide and domain registration protections such as clientTransferProhibited status. The website includes a cookie consent mechanism compliant with GDPR, and IP anonymization is enabled in analytics tools. However, the absence of DNSSEC and limited visible security headers indicate potential areas for enhancement. No incident response or vulnerability disclosure information is publicly available, which could be a gap in transparency and readiness. No signs of exposed sensitive data or vulnerable libraries were found. Overall, the security posture is good but could be improved by adopting additional DNS and HTTP security best practices and publishing clear security policies and contact channels.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Publish a security.txt file or a dedicated vulnerability disclosure policy page to facilitate responsible reporting of security issues.
  3. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear incident response contact information, such as a security@ or abuse@ email address, to improve transparency and responsiveness.
  5. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using modern frontend technologies, primarily Vue.js, and integrates several third-party services including Google Tag Manager, PostHog analytics, and Partnero marketing tools. Hosting is inferred to be on AWS based on DNS servers. The site is well-optimized for performance and mobile responsiveness, with a clean and professional design. SEO best practices are followed with proper meta tags and canonical URLs. Accessibility features are present but not deeply detailed. The use of asynchronous and deferred script loading improves page load times. Cookie consent is managed via Cookie Script, ensuring compliance with privacy regulations. Overall, the technical infrastructure supports a robust and scalable SaaS platform with good user experience and compliance readiness.
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.
