脆弱性の開示ポリシー

At Netskope, we take our responsibility to protect our users’ information and the services we provide to them very seriously.

We want security researchers to feel comfortable reporting vulnerabilities they’ve discovered, as set out in this policy so that we can remediate them and help us keep our information safe.

This policy describes what systems and types of research are covered under this policy, how to send us vulnerability reports, and how long we ask security researchers to wait before publicly disclosing vulnerabilities.

Guidelines

We require of you to:

Make every effort to avoid privacy violations, 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. Do not use an exploit to compromise or exfiltrate 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 encountered any of the sensitive data outlined below, you must stop your test and notify us immediately.
Keep confidential any information about discovered vulnerabilities. For details, please review the Coordinated Disclosure section.

Scope

This policy applies to the following domains:

Any services not expressly listed above, such as any connected services, are excluded from the scope and are not authorized for testing.

Additionally, vulnerabilities found in our service providers’ systems fall outside of this policy’s scope and should be reported directly to the service provider according to their disclosure policy (if any). If you are not sure whether a system or endpoint is in scope or not, contact us at PSIRT@netskope.com before starting your research.

A subset of these systems may be eligible for bounties. Check our program page on BugCrowd for the current list of bounty-eligible systems.

The following test types are not authorized:

User interface bugs or typos.
Network denial of service (DoS or DDoS) tests.
Physical testing (e.g. office access, open doors, tailgating), social engineering (e.g. phishing, vishing), or any other non-technical vulnerability testing.

If you encounter any of the below on our systems while testing within the scope of this policy, stop your test and notify us immediately:

Personal identifiable information
Financial information (e.g. credit card or bank account numbers)
Proprietary information or trade secrets of companies of any party
Denial of Service or situations where the site and application are not responding

コンプライアンス

If you comply with this policy during your security research and do not compromise the security of our systems, or the safety or privacy of our users, we will work with you to understand and resolve the issue quickly, and will not initiate or recommend legal action related to your research.

Reporting a vulnerability

In addition to our Bug Bounty program, we accept and discuss vulnerability reports via email at PSIRT@netskope.com. We also ask that if the BugCrowd program is not open or available please share any vulnerabilities with PSIRT@netskope.com and we will work to get you recognition via the BugCrowd program when it becomes available. Reports may be submitted anonymously. Note: We do not support PGP-encrypted emails. For particularly sensitive information, submit through our BugCrowd program.

We prefer reports via BugCrowd but will respond to reports through any of the above channels. Note, however, that only reports submitted via BugCrowd will be eligible for bounties, where applicable.

Reports should include:

Description of the location and potential impact of the vulnerability.
A detailed description of the steps required to reproduce the vulnerability. Proof of concept (POC) scripts, screenshots, and screen captures are all helpful. Please use extreme care to properly label and protect any exploit code.
Any technical information and related materials we would need to reproduce the issue.

Please keep your vulnerability reports current by sending us any new information as it becomes available.

We may share your vulnerability reports with US-CERT, as well as any affected vendors or open source projects.

Coordinated Disclosure

Netskope is committed to patching vulnerabilities within 90 days or less and disclosing the details of those vulnerabilities when patches are published. We know that public disclosure of vulnerabilities can be an essential part of the vulnerability disclosure process and that one of the best ways to make software better is to enable everyone to learn from each other’s mistakes.

At the same time, we believe that disclosure in absence of a readily available patch tends to increase risk rather than reduce it, and so we ask that you refrain from sharing your report with others while we work on our patch. If you believe there are others that should be informed of your report before the patch is available, please let us know so we may consider other arrangements.

We will want to coordinate an advisory with you to be published simultaneously with the patch, but you are also welcome to self-disclose if you prefer. By default, we prefer to disclose everything, but we will never publish information about you or our communications with you without your permission. In some cases, we may also have some sensitive information that should be redacted, and so please check with us before self-disclosing.
