Steve Levinson Resized

"You know, Jeff Man didn’t just get into cybersecurity, he helped build the whole thing. Back in the day, he was at the NSA, knee-deep in cryptography before most of us even knew what a cipher was. Fast forward a few decades, and the core team that makes up OBS Cybersecurity was already taking shape.

Several of us worked together at VeriSign in the mid-2000s, cutting our teeth on PCI and a few years later, we found ourselves building at a cybersecurity practice at OBS.  Jeff took a detour, spent some time with a buddy’s company, but in 2018, he finally joined us.

While Jeff is still breaking things and petting the cat the wrong way, he’s still asking the tough questions of clients, partners, and co-workers alike, and let’s be honest, still making compliance sound way cooler than it actually is.  And when it comes down to it, humans learn best through song and story, and there’s no better storyteller than Jeff!"  ~   Steve Levinson, Vice President RSP
