Is it possible to connect 2 firewalls directly for a site-to-site VPN?

Is there a way to connect 2 Cisco firewalls directly to establish a site-to-site VPN over straight-through cabling? I need the features of the firewalls on each side of the networks but I don't want to lose throughput. In the past, you could do this with a switch in the middle but I hated having that extra device to keep up with.

I think it's possible with crossover cables but I'm also don't want to lose throughput.

Any features on modern enterprise firewalls that would allow this? Cisco preferred if possible but I'm comfortable with other brands if it's definitely possible.
