Nov 28 (Reuters) - Splunk (SPLK.O) beat quarterly estimates for revenue on Tuesday, helped by resilient demand for its cybersecurity offerings in an uncertain economy. Cisco Systems (CSCO.O), which cut its annual revenue and profit forecasts earlier this month, entered into an agreement to buy Splunk for about $28 billion in September to strengthen its software business. Splunk is known for its strengths in the area of data observability, which helps companies monitor their systems for cybersecurity risks and other threats. Splunk's total annual recurring revenue for the third quarter ended Oct. 31 rose 15% to $4 billion. It reported total revenue of $1.07 billion, beating analysts' expectations of $1.03 billion, according to LSEG data.
