Disclosure Policy

Our Responsible Vulnerability Disclosure Policy
The following Cybellum Zero Day Disclosure Policy outlines how Cybellum handles
responsible vulnerability disclosure to product vendors, Cybellum customers, and the general
public. It also reassures product vendors that there is a professional and standard set
of guidelines they can expect to be utilized throughout the disclosure process.

Policy
Cybellum will responsibly and promptly notify the appropriate product vendor of a
security flaw with their product(s) or service(s). The first attempt at contact will be
through any appropriate contacts or formal mechanisms listed on the vendor Web site,
or by sending e-mail to security@company.com with the pertinent information about the
vulnerability. Simultaneous with the vendor being notified, Cybellum may distribute
new security to its customers.

If a vendor fails to acknowledge Cybellum’s initial notification within five (5) business days,
Cybellum will initiate a second formal contact by a direct telephone call to a
representative for that vendor. If a vendor fails to respond after an additional five (5)
business days following the second notification, Cybellum may rely on an intermediary
to try to establish contact with the vendor. If Cybellum exhausts all reasonable means
in order to contact a vendor, then Cybellum may issue a public advisory disclosing its
findings fourteen (14) business days after the initial contact.

If a vendor response is received within the timeframe outlined above, Cybellum will
allow the vendor ninety (90) days to address the vulnerability with a patch. At the end of
the deadline if a vendor is not responsive or unable to provide a reasonable statement
as to why the vulnerability is not fixed, Cybellum will publish a limited advisory
including mitigation in an effort to enable the defensive community to protect the user.
We believe that by doing so the vendor will understand the responsibility they have to
their customers and will react appropriately.

We realize some issues may take longer than the deadline due to complexity and
compatibility reasons and we are willing to work with vendors on a case-by-case basis.
To maintain transparency into our process, if any vulnerability is given an extension we
plan on publishing the communication we’ve had with the vendor regarding the issue
once it is patched. We hope that this level of insight into our process will allow the
community to better understand some of the difficulties vendors have when remediating
high-impact bugs. Cybellum will make every effort to work with vendors to ensure they
understand the technical details and severity of a reported security flaw. If a product
vendor is unable to, or chooses not to, patch a particular security flaw, Cybellum will
offer to work with that vendor to publicly disclose the flaw with some effective
workarounds. In no cases will an acquired vulnerability be ‘kept quiet’ because a
product vendor does not wish to address it.

Cybellum will formally and publicly release its security advisories on its Web site and
on selected security mailing list outlets.
