According to CRN, SentinelOne unveiled a sweeping AI security strategy at its OneCon 2025 conference in Las Vegas, launching multiple products from recent acquisitions including its $180 million Prompt Security buy and $225 million Observo AI deal. The company debuted Prompt Security for Employees to combat “shadow AI” across 15,000 services, plus AI code assistant protection and security for custom AI applications, all generally available now. They also introduced Wayfinder Threat Detection and Response services through a Google Cloud partnership and expanded Purple AI with agentic auto-investigations currently in preview. CEO Tomer Weingarten stated that much of the cybersecurity technology sold over the past decade will become “irrelevant” as AI agents transform the landscape.

The platform play is everything now
Here’s the thing about SentinelOne’s moves – they’re not just adding features. They’re building what they hope will become the central nervous system for enterprise security. When the CEO openly says most of what we’ve been selling for the past decade will become irrelevant, that’s a pretty bold statement. But it makes sense when you look at where AI is taking us.
Basically, they’re betting that companies will want one platform to manage all their AI security risks rather than a dozen point solutions. The Prompt Security acquisition gives them visibility into employee AI usage across thousands of tools. The Observo AI deal helps optimize data pipelines. And the Google partnership brings threat intelligence. It’s all about creating this comprehensive ecosystem.
Who wins and loses in this shift?
If SentinelOne’s vision plays out, the traditional SIEM market could get absolutely rocked. Their claim that Singularity AI SIEM is “the only SIEM on the market” that can analyze data before it’s added to the system? That’s a direct shot at established players. And when you combine that with agentic investigations that can handle everything from discovery to response recommendations, you’re talking about replacing a lot of manual security work.
But here’s the interesting part – they’re not just going full automation. The Wayfinder managed services combine AI with “elite-level” human experts. So they’re acknowledging that for now at least, you still need people in the loop. The question is, for how long? If these AI agents get good enough, even those premium MDR services might eventually get automated.
What this means for pricing and competition
Look, when a company spends $405 million on two acquisitions in quick succession, they’re playing for keeps. SentinelOne is clearly trying to position itself as the AI security leader before the market fully consolidates. The open-source Purple AI MCP Server on GitHub is a smart move too – get developers building on your platform and you create serious lock-in.
Pricing in this new AI security world is going to be fascinating. Will companies pay premium prices for AI agents that theoretically reduce their staffing costs? Or will competition drive prices down as automation becomes table stakes? One thing’s for sure – the cybersecurity landscape Weingarten describes, where AI agents displace traditional tools, creates massive opportunities for providers who get there first. The race is officially on.
