Why Prompt Security Built a New AI Security Category, Not Just Features

Enterprises now face an estimated $4.63 million cost per shadow AI breach, with AI usage inside companies growing 61x in just two years. Prompt Security launched in August 2023 to tackle this explosive risk and secured a reported $250 million acquisition by SentinelOne in August 2025.

This isn’t about protecting isolated AI features — it’s about building a platform that governs all AI interactions at the enterprise level, converting AI security from a line item into a strategic control layer.

“I wasn’t trying to win a feature race; I was building a new category,” says Itamar Golan, Prompt Security’s co-founder and CEO.

Enterprises that embed AI security holistically avoid reactive patchwork and gain lasting leverage.

Why AI Security Is More Than a Feature

Conventional wisdom treats generative AI security as tangential or narrowly technical — focusing on stopping prompt injection or blocking tools. This misses the systemic explosion of shadow AI and data leakage risks.

Unlike feature-centric startups, Prompt Security positioned itself as a comprehensive AI security control layer. That means protecting every touchpoint — browsers, IDEs, internal tools, and AI agents — at runtime, not only inside explicit IT sandboxed AI.

This shift flips the constraint. Protection is no longer a point solution but an embedded platform function sitting at the CISO’s strategic table, creating new budget authority and long-term relevance — a system-level move rather than tactical firefighting.

Strategic restraint repositions AI risk from a governance headache to a platform advantage. This echoes leveraged positioning seen in finance where system design trumps quick fixes.

Enterprise Complexity: A Hard Constraint Turned Advantage

While others resisted, Prompt Security embraced enterprise complexity early, building self-hosted and hybrid deployment models that cover real-world enterprise surfaces.

This choice produced a durable moat. Competitors relying on cloud-only or feature-limited models cannot replicate the enterprise-ready platform that integrates tightly with the broad AI attack surface. It’s a constraint repositioning: investing upfront in complex enterprise requirements yields outsized later returns.

This differs sharply from startups chasing vanity logos or rapid volume. Instead, Prompt Security went deep with fewer, serious customers, embedding into their AI governance and risk practices to co-evolve the product.

For readers, this mirrors lessons from operational shifts in technical organizations where embracing complexity accelerates lasting leverage.

From Incident to Insight: Why AI Democratizes Exploit Risk

A pivotal moment was a breach at a regulated customer-facing AI agent. Despite standard security controls, a non-technical user cleverly manipulated AI conversation to extract highly sensitive customer data.

This democratization of hacking — where creativity beats coding skill — fundamentally expands AI’s attack surface and compresses time to exploit discovery. It forced Prompt Security to double down on runtime protections and cross-tenant data leakage prevention.

This incident reframes the security constraint: AI is no longer a black box to defend but a complex interface demanding proactive dynamic safeguards, a system response rather than perimeter defense.

Much like lessons from Anthropic’s AI security exposure, this reveals why integrated platforms outperform bolt-on features.

What Comes Next? Platform Integration Unlocks Scale

Now under SentinelOne, Prompt Security extends AI runtime protection across endpoints, identities, and cloud workloads via the Singularity Platform.

Combining model-agnostic safeguards with broad surface area coverage—spanning OpenAI, Anthropic, Google’s LLMs, and on-prem models—creates a wide defensive moat few can match.

This is not incremental product enhancement; it’s a platform-level leap that shifts the entire cybersecurity cost and risk equation.

Enterprises that embed AI security early gain defensive leverage that protects IP, customer trust, and operational continuity across the AI adoption curve.
