Shares of ZScaler (ZS.O) and other cybersecurity firms have declined sharply after the company issued weaker-than-expected guidance for the current quarter.

The sell-off has rippled through the sector, with investors reassessing risk exposure in the space.

ZS.O shares are down over 10% in early trading, with peers like CrowdStrike and Palo Alto Networks also seeing declines.

However, analysts caution that the move is more reflective of ZScaler's internal challenges than a systemic threat to the broader cybersecurity market.

The cybersecurity sector had been gaining momentum in recent weeks, with ZScaler's upcoming earnings report drawing particular attention.

The company's revised outlook, which cited ongoing customer budget constraints and slower deal cycles, has triggered a broader selloff.
