The simple answer is, yes. Technical product issues will be investigated using existing maintenance process of Sophos, on the basis that the problem can be replicated in their testing environments on the platforms listed in the Sophos Protection for Linux release notes. Only the last two minor releases of a tested platform version are fully supported. Earlier minor releases will receive the best efforts and may fall outside the scope of Sophos Support. For a list of tested platforms and other important details about this product, see Sophos Protection for Linux release notes.
