TL;DR
- HiddenLayer concentrates on the model itself: file scanning, adversarial ML detection, and monitoring of LLM inputs and outputs, delivered mainly through SaaS.
- AccuKnox secures the model and the infrastructure around it, pairing AI-SPM posture management with eBPF runtime enforcement from KubeArmor.
- The AccuKnox Prompt Firewall sits inline at the AI gateway (Azure APIM, AWS API Gateway, LiteLLM, Bifrost AI) and can block, alert, or redact before a prompt reaches the model.
- AI-DR in AccuKnox reads CloudTrail and Azure logs to surface shadow AI, unapproved notebooks, and risky AI resource creation. HiddenLayer does not ingest cloud infrastructure logs for this.
- Deployment differs sharply: AccuKnox ships the same feature set on SaaS, on-prem, and air-gapped installs, while HiddenLayer is SaaS-first with limited disconnected support.
Frequently Asked Questions: AccuKnox vs HiddenLayer
Does AccuKnox replace HiddenLayer, or sit alongside it?
Most teams replace it. HiddenLayer's strength is model-layer analysis, and AccuKnox covers that same ground with static scanning of Pickle, TensorFlow SavedModel, GGUF, and DDUF files, then adds AI-SPM posture, AI-DR, and eBPF runtime enforcement in one console. If you already run HiddenLayer for supply chain scanning, AccuKnox can be introduced at the gateway and runtime layers first.
What is the architectural difference between a Prompt Firewall and a prompt analyzer?
A prompt analyzer inspects traffic and raises detections from the application side. The AccuKnox Prompt Firewall runs inline at the gateway (Azure APIM, AWS API Gateway, LiteLLM, Bifrost AI), so a jailbreak attempt or a PII leak can be blocked or redacted before it reaches the model or the user. No changes are required on the model side.
Can either platform run in a fully air-gapped environment?
AccuKnox can. On-prem and air-gapped installs carry the same feature set as SaaS, with single-node, managed Kubernetes (EKS, AKS, GKE), and AWS AMI control plane options. HiddenLayer documents a hybrid disconnected mode but is built SaaS-first.
Which platform finds shadow AI?
AccuKnox AI-DR ingests CloudTrail and Azure logs to discover unapproved notebooks, models, and AI services across AWS, Azure, and GCP, then flags risky AI resource creation against a baseline. HiddenLayer detects threats inside AI interactions but does not read cloud infrastructure logs for discovery.
How does each handle agentic AI and MCP servers?
Both sandbox MCP tools. AccuKnox goes further on identity, issuing SPIFFE-based workload identity to agents and applying OpenFGA authorization with upstream caller sequence tracking, plus auto-discovery of agents and MCP servers across clouds.
