Zscaler agreed to buy managed detection and response (MDR) specialist Red Canary as it looks to expand into the security operations centre. 

Red Canary promised that its products will “continue to integrate with the 200+ technology and security products they currently do, and we’ll keep expanding that number” and committed to existing partners. 

Zscaler CEO Jay Chaudry said the deal would "accelerate our vision of AI-powered SOC of the future". Terms of the deal were not disclosed. 

One unattributed third-party report put the acquisition figure at $4 billion but The Stack could not immediately confirm the sum with Zscaler. 

Red Canary provides a security automation orchestration and response (SOAR) and can plug into EDR’s from the likes of Crowdstrike, Microsoft, and SentinelOne, as well as pulling telemetry from cloud control planes. 

The acquisition comes just over a year after Zscaler spent $340 million on Israeli security risk data startup Avalor, with Chaudry stating the company would use data from Avalor to help train its "security specific" LLMs.

(Red Canary claimed in January that its AI agents had reduced incident investigation time for SOC analysts by an average of 90%.)

The startup reported ARR of $140 million in its most recent earnings.

CEO Brian Beyer promised existing customers would see a "seamless experience" as the two companies combined "strategic parts" of their security and IT stack, and promised existing partners like CrowdStrike and Palo Alto Networks, would remain "critical to our strategy."

Zscaler will share more details in Q3 earnings on May 29.
