(Reuters) -CrowdStrike shares fell about 3% before the bell on Thursday after the cybersecurity firm's weak quarterly revenue forecast signaled the lasting effects of a botched update last year that caused a global outage.

The company projected third-quarter sales broadly in line with analysts' expectations as incentive programs and discounts tied to the outage weigh on the timing of subscription revenue, as it lets customers pick more products or extend usage.

Last year, a faulty update to CrowdStrike's Falcon sensor software triggered a Windows malfunction and caused technology systems in hospitals, banks, and airports to go dark.

The company's second-quarter revenue jumped 21%, indicating cybersecurity demand remains strong despite the volatility due to investments in artificial-intelligence-powered safety systems amid a rise in digital threats.

Morningstar analysts said on Thursday the share price reaction was largely "due to inflated near-term expectations baked into the stock going into the earnings report."

CrowdStrike's shares have gained 23.5% so far this year.
