CCIE Security is probably useful, although that's more CCIE + Security than some abstract security cert, too, and specifically for network security, and specifically the kind of network you get in a corporate environment, not a startup/saas.
I'm not sure how I feel about SANS/GIAC. Absurdly expensive IMO, but potentially actually has some value for sysadmins doing system security. I can't think of what CISSP is actually good for, except maybe trivial pursuit - crappy consultant edition.
Somewhat related - about 2 years ago, my employer had a bunch of us go through the SANS/GIAC GSSP training & certification. Some of the material was pretty boring and of questionable utility, but we had a good instructor and some of the hands-on parts where we were finding vulnerabilities was actually really fun.
I'm under no illusions about the certification's marketplace value and I doubt I would have ever paid for the course/cert on my own, but it felt like one of the better formal trainings I've been through in my professional career (which, granted, isn't saying a whole lot by itself).
Also, the certificate comes mounted on a comically oversized plaque, which provides some entertainment value.
But to be clear: I believe pretty firmly that for technical / software security, the CISSP is useless.
