Cloud-technology cybersecurity company CrowdStrike (CRWD) kicked off its initial public offering on a high note on Tuesday, opening for trading at $63.50 a share, well above its IPO price of $34.

The Sunnyvale, Calif.-based company, which uses the slogan "Breaches Stop Here," was expected to price its 18 million Class A shares at between $28 and $30 a share, netting it approximately $600 million.

CrowdStrike joins several other big tech companies that have taken the IPO route this year, including Uber (UBER) , Pinterest (PINS) , Zoom Video (ZM) and Lyft (LYFT) -- and one big non-tech IPO, Beyond Meat (BYND) .

Office-messaging platform provider Slack is expected to follow later this month.
