Morgan Stanley’s Meta Marshall on Where AI Will Disrupt Cybersecurity Markets
Meta Marshall, managing director, Morgan Stanley
The cybersecurity vendor market is at an inflection point, with frontier lab entrants poised to either accelerate growth or disrupt it. The outcome depends largely on which market segments they can realistically compete in.

“There is always going to be best of breed. Platformization means getting to 20 or 30 vendors from 50 or 60 vendors; it doesn’t mean going to one or two,” said Meta Marshall, managing director at Morgan Stanley. The $270 billion security market remains the prize. But unlocking it requires moving artificial intelligence adoption from consumer experimentation into enterprise frameworks where security budgets reside.
Marshall said the biggest exposure is in batch-based, lower-accuracy segments such as threat monitoring, where large language models can process alerts at scale. Real-time systems, including network and identity security, remain more defensible due to speed and accuracy constraints.
In this video interview with Information Security Media Group at RSAC Conference 2026, Marshall also discussed:
- Why security concerns and innovation overload are the two biggest inhibitors of enterprise AI adoption;
- How AI adoption mirrors the early consumer-to-enterprise arc of cloud computing;
- Why identity security vendors must innovate to address non-human identities or risk being replaced.
Marshall is Morgan Stanley’s cybersecurity, network and equipment analyst. Prior to joining Morgan Stanley, she was vice president of the Technology Investment Banking group at Bank of America Merrill Lynch. Marshall specializes in technology sector research with a focus on cloud communications, networking and infrastructure software.
