LIFELOCK ACTUALLY HAS DMARC Enforcement. THE BAD NEWS: Norton Doesn't.
Now for the bad news. With LifeLock, you also get "Norton with LifeLock" for your personal computer. Sadly, Norton.com themselves are not protected. I can't fault the LifeLock CISO. It's the LifeLock marketing team, which succumbed to the Norton marketing team's giveaway. Given that 43% of the PC hijacking taking place bypasses Norton technology (see my MadCISO article here), my advice is simple: Get LifeLock and say thanks but no thanks to their free Norton suite.
