The top AI-SPM vendors in 2026 are Wiz (Google), Palo Alto Networks, Noma Security, HiddenLayer, Zenity, Orca Security, Cato Networks, Aqua Security, AccuroAI and Akto — split between platform modules and independents after eighteen months of heavy consolidation.
Ranking AI security posture management vendors in 2026 means ranking a market that just reorganised itself. Five independent AI security companies were absorbed by platforms in under two years — Protect AI into Palo Alto, CalypsoAI into F5, Aim Security into Cato, Robust Intelligence into Cisco, and Wiz itself into Google for $32 billion, closed March 2026. The independents that remain raised at scale: Noma to $132 million total, HiddenLayer past $155 million, Zenity to roughly $185 million. The real decision is no longer "which AI-SPM tool" but "platform module or specialist" — and this ranking is built accordingly. For the category definition, start with our AI-SPM explainer; for a capability-matrix cut of the same market, see our 2026 vendor landscape.
What is AI-SPM, and how is it different from DSPM and CSPM?
The cleanest working distinction: CSPM finds misconfigurations in cloud infrastructure; DSPM finds where sensitive data lives and who can reach it; AI-SPM inventories and hardens the AI layer itself — models, agents, pipelines, training data and AI services — including risks the older categories were never designed to see: model poisoning, prompt-injection paths, exposed model endpoints and shadow AI.
Vendors converge on this. Wiz defines AI-SPM as the discipline that "discovers, monitors, and remediates risks specific to AI models, pipelines, datasets, and services running across cloud environments," and claims to have coined the term as the first CNAPP to ship it — a vendor claim, but uncontested. Palo Alto calls AI-SPM "the security response to AI adoption." Gartner, paraphrased via Cyberhaven's summary since the primary research is paywalled, frames AI-SPM tools as scanning infrastructure to discover deployed models, assistants, agents and their data pipelines, inside the broader AI TRiSM umbrella. One Gartner-derived statistic explains the posture emphasis: per vendor recaps of the 2025 AI TRiSM Market Guide, Gartner expects 80% of AI failures to come from internal misuse, oversharing or unintended outputs, not external attacks.
If your AI estate is mostly employees using SaaS AI rather than self-hosted models, note that AI-SPM overlaps but does not coincide with an AI control plane — our control plane pillar maps the difference, and if you are wondering whether Microsoft's native tooling already covers you, we have answered that separately.
Who are the top 10 AI security posture management vendors in 2026?
Ranking criteria: breadth of AI-estate discovery, depth of posture and scanning capability, runtime and agent protection, and evidence of enterprise traction. One row below is ours; we disclose it and rank it where the evidence puts it, not where marketing would.
1. Wiz (Google Cloud)
Launched AI-SPM in November 2023, billed as the first CNAPP to do so. Strongest at AI-BOM — a centralised bill of materials tracking every model, service, SDK and pipeline — plus misconfiguration rules for OpenAI and Bedrock services, attack-path analysis, and AI-SPM for agents. The $32 billion Google acquisition closed 11 March 2026; Wiz keeps its brand inside Google Cloud. Buyers on AWS and Azure should ask how neutral a Google-owned posture tool stays.
2. Palo Alto Networks (Prisma AIRS)
Prisma AIRS launched at RSAC 2025 spanning model scanning, posture management, red teaming, runtime security and agent security; the Protect AI acquisition (completed July 2025, estimated at $650–700 million by Jefferies analysts) was folded in fully with AIRS 2.0 in October 2025. The widest dev-to-runtime span on this list, priced and packaged for existing Palo Alto estates.
3. Noma Security
The strongest specialist claim to end-to-end "data and AI lifecycle" coverage: supply chain, AI-SPM discovery of agents and MCP, and runtime protection. $132 million raised in under two years. Credibility marker: Noma's researchers found ForcedLeak, the CVSS 9.4 Salesforce Agentforce flaw. No public pricing.
4. HiddenLayer
Model-security heritage (scanning, genealogy, AI-BOM in AISec 2.0) now extended to agentic runtime; named in the 2025 Gartner AI TRiSM Market Guide and listed for US federal procurement via AWS. $100 million Series B announced September 2026. The pick when model supply chain integrity is your lead requirement.
5. Zenity
Agent-layer governance for the business platforms where agents actually get built — Copilot Studio, Agentforce, low-code estates — with posture and inline enforcement. $125 million Series C in August 2026 with SoftBank, Hitachi and LG among the backers. Less about cloud model pipelines, more about the agent sprawl in your tenant.
6. Orca Security
Agentless AI-SPM via SideScanning since March 2024: sensitive data in training sets, data-poisoning risk from editable training data, misconfigurations mapped to the OWASP LLM and ML Top 10 lists, and detection across 50+ model types per CSO Online's buyer's guide. The lowest-friction way to add AI posture to an existing cloud security programme.
7. Cato Networks
Bought Aim Security in September 2025 — Cato's first acquisition, officially undisclosed, roughly $350 million per Calcalist — and now sells "AI Security (AISEC)" inside its SASE platform, covering employee AI use, private AI apps and development pipelines from the network layer. The consolidation play.
8. Aqua Security
"Secure AI," unveiled April 2025, covers the full lifecycle "from code to cloud to prompt," with AI cloud service configuration checks explicitly labelled AI-SPM and runtime protection needing no code changes. Natural fit where Aqua already owns your container security.
9. AccuroAI
Disclosure: this is us. Our posture strength is the shadow side of the estate — discovery against a 1,400+ tool catalog, with customers measuring a 94% reduction in shadow AI within 30 days — paired with runtime enforcement at a self-reported <38ms p99 across 14M+ daily prompts, and compliance mapping to 8 frameworks that customers report makes audit prep 11× faster. We are 15 enterprises strong, not a thousand; we rank ourselves ninth on traction, not capability, and you should verify our claims in a 72-hour pilot like you would anyone else's. Start with the agent security platform.
10. Akto
API-security roots, aggressive agentic pivot: MCP security in June 2025, then a full Agentic Security Platform in September 2025 — agent and MCP server discovery, 1,000+ exploit tests, automated red teaming and runtime guardrails. Thinly funded ($4.5 million seed led by Accel India) but shipping fast. Its own survey — vendor research, weigh accordingly — found 69% of enterprises deploying AI agents while only 21% have the visibility to secure them.
Also watch: Cranium (the KPMG spin-out, strong on compliance mapping, with an EU AI Hub built with KPMG and Microsoft), Mindgard (offensive AI security, $30 million Series A in August 2026), Operant AI (runtime and MCP security), and Lasso Security (GenAI guardrails; a 2025 Gartner AI TRiSM Representative Vendor — funding omitted because public sources conflict).

The pricing column is the category's quiet scandal: not one of the ten publishes list pricing. Budget conversations run on marketplace signals and quotes, which is worth remembering when a vendor's ROI deck seems suspiciously precise.
How big is the AI-SPM market?
Honest answer: young, fast-growing, and measured mostly by firms you should quote with hedges. SNS Insider sizes AI-SPM at $5.78 billion in 2025, projecting $50.46 billion by 2035; Globe Market Research lands nearby at $6.8 billion for 2026. Both are smaller research shops — treat the figures as directional — and do not confuse them with the far larger "AI for cybersecurity" market most headline reports measure. The harder signal is M&A: platforms paid real money (an estimated $650–700 million for Protect AI, $180 million announced for CalypsoAI — F5's SEC filings record $145.2 million of actual cash paid — and a reported $350 million for Aim) because customers were already asking for the capability.
How should you evaluate an AI-SPM vendor?
- Module versus standalone first. Most buyers get AI-SPM as a module of a platform they already own; the consolidation decision matters as much as any feature. Standalone specialists win where the platform's module trails their roadmap by quarters.
- Agentless discovery of the full estate, shadow AI included. Per both Orca's and AccuKnox's buyer's guides — self-interested, but right — discovery breadth and attack-path prioritisation are the two most differentiating criteria. Ask exactly what requires extra instrumentation to see.
- Continuous scanning, not snapshots. CSO Online's buyer's guide stresses this given how fast AI estates change; citing Microsoft's 2026 Cyber Pulse report, it notes the average enterprise manages 37 agents, over half without security oversight — a figure we pass along secondhand.
- Demand a live runtime demo. Make the vendor block a prompt injection or an agent misuse attempt in front of you, not show an inventory dashboard. Posture without enforcement is a very expensive spreadsheet.
- Probe the vendor's origin. A CSPM heritage means strong cloud coverage and weak agent context; a model-scanning heritage means the reverse. Blind spots follow birthplaces.
- Check stack integration. SIEM, SOAR and DLP integration determines whether findings become tickets or wallpaper.

FAQ
What is the difference between AI-SPM, DSPM and CSPM?
CSPM finds cloud infrastructure misconfigurations; DSPM finds and classifies sensitive data and its exposure; AI-SPM inventories and hardens AI assets themselves — models, agents, pipelines and training data — covering AI-specific risks like model poisoning, prompt-injection paths and shadow AI that the older categories miss.
Do I need AI-SPM if I already have a CNAPP?
Check what your CNAPP's AI module actually covers — Wiz, Orca and Aqua all ship real AI-SPM capabilities. The gaps appear around SaaS AI usage, employee shadow AI and agent runtime behaviour, which cloud-posture heritage tools observe poorly. Many enterprises run a CNAPP module plus a specialist for exactly those gaps.
What does AI-SPM cost?
No major vendor publishes list pricing; deals are quote-based, and platform modules are usually priced as add-ons to existing licences. Use proof-of-concept commitments as leverage — a vendor confident in discovery should be willing to show you your own shadow AI before you sign.
Which AI-SPM vendors are still independent in 2026?
Noma Security, HiddenLayer, Zenity, Akto, AccuroAI, Cranium, Mindgard, Operant and Lasso remain independent as of September 2026. Wiz (Google), Protect AI (Palo Alto), Aim Security (Cato), CalypsoAI (F5) and Robust Intelligence (Cisco) have been absorbed — and the funding pace suggests the independents' list will shorten again before 2027.
