How fast is the AI Security market expected to grow?

Industry researchers project the AI in cybersecurity segment to expand from about $22.4 billion in 2023 to roughly $60.6 billion by 2028. This growth is driven by the dual need to use AI for defense and to secure AI systems themselves across cloud and enterprise environments.

Where are investors concentrating capital within AI Security?

Capital is flowing to platforms that can deploy AI at scale for cloud posture, detection, and response, as well as to specialists that secure models, data, and AI supply chains. Late-stage rounds favor companies with strong enterprise traction, while early-stage funding targets LLM guardrails, adversarial testing, and MLOps security.

What regulatory frameworks are influencing enterprise buying decisions?

The NIST AI Risk Management Framework is becoming a reference point for governance, measurement, and continuous oversight of AI systems. In Europe, obligations stemming from the EU AI Act are prompting organizations to integrate model risk management with existing security and compliance programs.

What are the biggest technical challenges in securing AI systems?

Key challenges include preventing prompt injection and data leakage, detecting model poisoning, and ensuring provenance across training data and model dependencies. Organizations also grapple with aligning developer-friendly guardrails with security policies, without slowing product teams.

What should enterprises and investors watch over the next year?

Watch for standardized procurement checklists tied to AI governance frameworks, increased consolidation as platforms integrate specialist controls, and metrics-based buying focused on measurable risk reduction. Sectors with strict compliance requirements—finance, healthcare, and the public sector—are likely to lead adoption and budget growth.

AI Security investment accelerates as enterprises harden GenAI

The new frontier of cybersecurity funding

AI Security has moved from a niche concern to a board-level budget priority as companies embed generative AI across products and workflows. The market for AI-powered cyber tools and the security of AI systems is projected to expand from roughly $22.4 billion in 2023 to $60.6 billion by 2028, according to industry analysts, reflecting a rapid shift in enterprise spending toward automated detection, model governance, and supply chain controls, according to industry reports.

Unlike past hype cycles, this wave is grounded in two converging needs: using AI to defend sprawling cloud environments at machine speed, and securing the AI itself—models, prompts, training data, and pipelines—against adversarial manipulation and leakage. This builds on broader AI Security trends, including the rise of model risk management, red-teaming-as-a-service, and AI-native threat detection.

Capital flows: mega-rounds, resilience, and M&A

Deal flow has rebounded from 2023’s trough as investors coalesce around high-growth platforms and clear enterprise use cases. In May 2024, cloud security leader Wiz raised $1 billion at a $12 billion valuation to scale AI-driven prevention and posture management across multicloud estates, underscoring investor appetite for security platforms that can operationalize AI at scale, as reported by CNBC.

Beyond headline rounds, late-stage capital is selectively funding companies that secure the AI stack itself—covering model monitoring, adversarial testing, and AI supply chain scanning—while early-stage investors back specialized guardrails for LLM applications. Overall cybersecurity funding showed signs of recovery in 2024, with deal counts and growth rounds stabilizing as buyers prioritized consolidation and ROI, data from analysts shows. Strategic buyers have also been active, with public vendors absorbing niche capabilities in model governance, data lineage, and agent safety to round out platform narratives.

Demand drivers: regulation, risk, and real incidents

Regulatory tailwinds are reshaping procurement. The U.S. government’s AI Risk Management Framework is emerging as a baseline for enterprise controls, emphasizing governance, measurement, and continuous monitoring across model lifecycles; its adoption is expanding into highly regulated sectors, per NIST guidance...
