As far as I know these are the well known protocols that offer PFS

Are there any other well known protocols? Have any of these been shown to be insecure?

    $\begingroup$ One terminology nit: IPsec (RFC4301) itself doesn't provide perfect forward secrecy, as IPsec just handles the packet encryption (and other packet handling); perfect forward secrecy is a property of the keying protocol. Hence, it is IKE (both IKEv1 and IKEv2) that offers PFS; however IPsec keyed with a different protocol might not. $\endgroup$ – poncho Feb 27 '15 at 16:54
