Risk levelMedium

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

Oaktree Specialty Lending Corporation operates as a business development company providing investors access to Oaktree Capital Management’s credit platform. The company focuses on generating income and capital appreciation through flexible financing solutions emphasizing risk control and consistency. The website presents a professional and content-rich experience with investor relations, press releases, and market insights. Technically, the site uses modern frameworks such as Bootstrap 5 and is built on Sitefinity CMS, but suffers from slow load times and lacks a valid SSL certificate, impacting security posture. The security configuration is weak with no HTTPS, no security headers, and no DNSSEC, exposing the site to potential risks. Privacy compliance is well addressed with Evidon consent management and clear privacy and cookie policies. Overall, the site is functional and professional but requires urgent security improvements to protect users and enhance trust.

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. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

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

The company is positioned as a significant player in the finance sector, leveraging Oaktree Capital Management’s global investment expertise. Its business model centers on providing credit and financing solutions to companies while offering investors access to these opportunities. The website supports investor engagement with press releases and insights but lacks direct contact information, which may limit immediate customer interaction. The partnership ecosystem includes the parent company and investor relations subdomain. Growth indicators are implied through recent press releases and market commentary. The company maintains a consistent brand presence and professional content, supporting credibility in the financial services market.

Security posture

The current security posture is weak due to the absence of a valid SSL certificate and HTTPS enforcement, which is a critical vulnerability. The lack of security headers and DNS security measures further increases risk exposure. No incident response or vulnerability disclosure policies are publicly available, limiting transparency. However, the site does implement cookie consent management and uses reputable analytics tools with privacy considerations. The absence of contact information for security or incident reporting is a gap. Immediate remediation of SSL and security headers is recommended to improve security maturity and user trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC and configure CAA records to protect DNS and certificate issuance.
  4. Publish a security policy and vulnerability disclosure page including contact channels for incident reporting.
  5. Optimize website performance to reduce load times and improve user experience.
Technical notes

Notes

The website is built using Sitefinity CMS with Bootstrap 5 and jQuery for frontend components. Evidon scripts manage cookie consent, and Google Tag Manager is used for analytics. The site loads a large number of resources (106) and has a large page size (~200KB), resulting in slow load times (~13 seconds). Mobile responsiveness is good, but accessibility is basic. SEO is supported with meta tags and Open Graph data. Hosting appears to be via Cloudflare, but SSL is not properly configured, which is a significant technical risk. The site lacks modern security features such as HSTS, OCSP stapling, and session resumption. Overall, the technical infrastructure is modern but requires security and performance improvements.
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.
