Sophos Responsible Disclosure Policy

As a security company, keeping our customers safe is Sophos’s primary concern. Sophos is a member of the Cloud Security Alliance. All Sophos products are created with security in mind, security from attacks against the systems we are protecting, and attacks on our software itself. Sophos also uses a Secure Development Lifecycle to bake security into its products from design through development and release. However, sometimes vulnerabilities escape detection, or new exploits are released after the product is already on the market.

At Sophos we investigate all vulnerability reports and implement the best course of action in order to protect our customers.

If you are a security researcher and have discovered a security vulnerability in our products, we appreciate your help in disclosing it to us in a responsible manner.

If you identify a verified vulnerability in compliance with Sophos’s Responsible Disclosure Policy, Sophos commits to:

  • Provide prompt acknowledgement of receipt of your vulnerability report (within 48 business hours of submission)
  • Work closely with you to understand the nature of the issue and work on timelines for fix/disclosure together
  • Notify you when the vulnerability is resolved
  • Publicly acknowledge your responsible disclosure (if you wish credit for such disclosure)

In Scope:

  • All vulnerabilities in Sophos products and online resources except those defined as Out of Scope

Out Of Scope

  • Resource exhaustion attacks against Sophos online products and services.

Sophos supports responsible disclosure, and we take responsibility for disclosing product vulnerabilities to our customers. We ask the security research community to give us an opportunity to correct a vulnerability within a reasonable time frame before publicly disclosing same, in order to ensure that Sophos has developed and thoroughly tested a patch and made it available to licensed customers at the time of disclosure.

Responsible disclosure guidelines suggest that customers have an obligation to patch their systems as quickly as possible, and it is customary to expect patching to be completed within 30 days after release of a security patch or update. Sophos advises its customers that those who exploit security systems often do so by reverse engineering published security updates and therefore encourages its customers to patch promptly.

Working together as a security community, we can ensure the best possible security for everyone.
