May 26 (Reuters) – Zscaler forecast fourth-quarter revenue below estimates on Tuesday, signaling intensifying competition in the cybersecurity market ​as enterprises scrutinize spending on cloud ‌security products, sending shares down 15% in extended trading.

• Despite the push to secure modern IT environments, Zscaler faces competition from larger rivals ‌such ​as Palo Alto Networks, ⁠which are vying ⁠for more market share with their own platform offerings.

• Zscaler primarily competes in the Secure Access Service Edge (SASE) market, which ​combines networking and security into a single platform to connect users, devices ⁠and applications from anywhere.

• ⁠SASE is one of the ​fastest-growing segments of cybersecurity as cloud adoption ​driven by the artificial intelligence boom continues ‌to transform network security architectures.

• The cloud-based security solution provider expects fourth-quarter revenue between $875 million and $878 million, below analysts’ ⁠average estimate of $878.6 million, according to data compiled by LSEG.

• Zscaler expects adjusted profit between $1.08 and $1.09 ⁠per ‌share in the fourth quarter, ⁠compared with estimates of $1.03.

• The company ​reported ‌revenue of $850.5 million in the ​third quarter, ⁠above estimates of $835.4 million.

• Its third-quarter total operating expenses rose about 25% to $687.5 million from $547.5 million a year ago.
