On September 23, Palo Alto Networks rose 3.14% in regular trading, trading at $385.91/share, with turnover of $543 million. The stock continued its upward momentum following a series of positive catalysts.

On the news front, Palo Alto Networks launched Unit 42 Continuous Frontier AI Defense, an agentic offensive security service designed to continuously identify, validate, and remediate enterprise cyber exposures. The service uses a proprietary multi-model AI harness integrating Anthropic's Claude Mythos 5, OpenAI's GPT-5.6-Cyber, and open-weight models combined with Unit 42's threat intelligence expertise. The offering provides an initial full-estate baseline scan followed by continuous testing as an organization's environment evolves.

The launch adds to a string of bullish developments. Morgan Stanley recently raised its price target to $410 from $394, maintaining an overweight rating, while the stock was officially added to the S&P 100 Index on September 21. The company also reported strong fiscal Q4 results, with adjusted EPS of $1.02 beating the $0.98 estimate and revenue of $3.41 billion exceeding the $3.35 billion consensus, as next-generation security ARR reached $9.1 billion, up 63% year over year.
