The troubled federal Obamacare website is not secure and needs to be shut down and rebuilt from scratch, cybersecurity expert Morgan Wright told CNBC on Thursday.
"It's not secure. We would not put our family on it. We wouldn't tell anybody to get on it; not at this time, not in the near future. There's not a plan to fix this that meets sniff test of being reasonable," Wright told CNBC's "Squawk Box" two days after he testified before a House panel looking into the problems.
"Many of the systems were already vulnerable," said Wright, a former law enforcement officer and now CEO of Crowd Sourced Investigations, a start-up that uses social media and crowdsourcing to try to solve crimes. "It would be very easy at this point to take the site down."
"There's no way to fix this plane while it's in flight. You have to put it on the ground," he continued. "We need to start all over again. We need health-care 2.0."

The online federal exchange, HealthCare.gov, has been plagued with technology problems since its launch on Oct. 1. Government officials and contractors have been making improvements overnight for weeks with the goal of having it running smoothly by the end of the month. It's a job Wright said he would never want: "You got a better chance of seeing God, because I wouldn't take the job."
"You can't achieve the outcome you want based on the current structure," he said, adding that building a whole new website would take "people from the private sector, not government contractors."

"You could do this with a team of 25 to 50 people and be done in less than a year," Wright said.
