anti-virus yes

auditing currently not - it's on the roadmap

Any idea when will CEPA for auditing be available?

Or even better, when will the file filtering be implemented?

planned for the next major release - for timeline you need to ask your local EMC or partner presales

simple file filtering based on file extension should work now - just like it does on VNX - that doesnt require CEPA

Any news about CEPA support on Unity ?

same plan - same answer - ask your local contact - no roadmap info on a public forum
