Probably, that might be the inside news. Though this is what our TAM had to say when the product got EOSL and we wanted to be sure that it does not have any potential impact.
We will continue to provide definition update for SAV9 as SAV10 is still supported and both product use the same definition file.
When SAV9 will be EOSL, basically we will not test anymore the definition on this product like we do for SAV8 or older version, so it can happened some issue with new engine for example that generate some problem with the product.
To be honest, at the moment we don’t have this kind of error with SAV8, so I don’t think it will happened with SAV9.
So to reply to your question, yes, we will continue to provide definition update to SAV9, but for a support point of view, we will recommend to you to upgrade to a higher (supported) version because if some bug are detected, we will not fix it anymore (i.e: Sygate SSE 4.1).
