This Sophos SF SW/Virtual Network Protection subscription gives you UTM-level traffic inspection on up to 1 CPU core with a 4GB RAM ceiling. Thirty-six-month term, so you're not chasing a renewal every twelve months. Deploy it in software, wire it into your virtual network, and stop worrying about what's sneaking through.
