Vulnerability discovery and disclosure policy

Version 1.3– November 2022


Sylvania considers that the safety, privacy and security of our customers is one of its top priorities. We design and make products and services with the best quality and reliability possible. Despite our efforts to implement the best possible security measures, vulnerabilities may still be present in our products and services.

This document describes Sylvania’s policy for receiving reports related to potential security vulnerabilities in its products and services, the company’s procedures in handling a report and the company’s standard practice with regards to informing customers of verified vulnerabilities.

Everyone is encouraged to report identified vulnerabilities, regardless the type of service or products. Researchers, partners, customers or any other source are welcomed to report any vulnerabilities found.


This policy applies to the following systems and services:

Note for researchers: Any service not expressly listed above are excluded from scope and are not authorised for testing.


We request that you:

  • Notify Feilo Sylvania first and as soon as possible after you have discovered a real or potential security issue
  • Make every effort to avoid privacy violations, degradation of system performance, degradation of user experience, disruption to production systems, and destruction or manipulation of data.
  • Only use exploits to the extent necessary to confirm a vulnerability’s presence.
  • Do not use an exploit to compromise or extract data, establish command line access and/or persistence, or use the exploit to “pivot” to other systems.
  • Once you’ve established that a vulnerability exists or encounter any sensitive data (including personally identifiable information, financial information, or proprietary information or trade secrets of any party),you must stop your test, notify us immediately, and not disclose this data to anyone else.
  • Give Feilo Sylvania reasonable time to resolve the issue
  • Do not use Network denial of service (DoS or DDoS) tests or other tests that impair access to or damage a system or data

If these guidelines are followed, no legal action will be taken against any persons discovering and reporting a vulnerability.
