The short version
An AI security platform is a bundle. The current product pages describe some mix of AI asset discovery, posture management, a gateway, runtime defense, red teaming, model scanning, and compliance reporting, sold as one enterprise product.
An agent firewall is one control. Pipelock sits on the agent’s routed network path, inspects HTTP, WebSocket, and MCP traffic, and blocks configured unsafe findings. With a signing key configured, it can emit signed action receipts for mediated decisions that verify offline against the operator’s key.
The platform question is about shape, not quality. Broad and managed, or narrow and verifiable.
How the platforms describe themselves
Prisma AIRS from Palo Alto Networks lists six components: AI Gateway, Agent Security, AI Red Teaming, AI Runtime Security, AI Model Security, and AI Posture Management. Compared in depth on Pipelock vs Prisma AIRS.
Noma Security positions a unified platform for end-to-end AI security, with offerings for the agents employees use on endpoints, agents running on SaaS platforms, and homegrown agents.
NeuralTrust lists TrustGuard for agent runtime security, TrustGate as an agent gateway that connects agents to models and tools, and agent posture management.
WitnessAI positions an AI security and governance platform: shadow AI discovery, an inventory of applications, MCP servers, and agents, and runtime defense for models, applications, and agents.
Runlayer and Backslash Security are control planes aimed at MCP access and developer endpoints, compared in depth on their own pages.
What a platform gives you that a firewall doesn’t
Discovery and inventory. Which agents, MCP servers, and AI applications exist across the organization. A firewall sees only the traffic routed through it.
Posture and reporting. Dashboards, compliance reports, and a vendor to hand an auditor. Pipelock maps its controls to OWASP, NIST 800-53, and the EU AI Act, and can emit signed receipts when configured, but it is not a reporting product.
Red teaming and model scanning. Platform components that test agents and models before and during deployment. Out of a firewall’s scope.
One contract. Procurement, support, and a named vendor behind everything.
What a firewall gives you that a platform doesn’t
Rules you can read. Every pattern and normalization pass is in a public repository. None of the platform pages read for this comparison publishes its detection logic.
A boundary you can run anywhere. One binary next to any agent, on a laptop, a CI runner, or a server, with no vendor service in the path.
Evidence a third party can check. With a signing key and allow-path receipt enforcement configured, Pipelock refuses to forward an allowed mediated request whose signed receipt cannot be emitted. The verifier checks signed receipts offline against a published key. The platform pages read for this comparison describe audit trails and reporting; they do not document a receipt format, a verifier, or a published key.
A fail-closed default you can inspect. A timeout or parse failure on a mediated path blocks the request. With a signing key configured, block decisions produce signed receipts.
Side-by-side
| AI security platform | Agent firewall | |
|---|---|---|
| Shape | Bundle of discovery, posture, gateway, runtime, red teaming, reporting | One control on the agent’s network path |
| Buying motion | Procurement and contract | Download and run; paid tiers for coordination and fleet |
| Detection logic | Not published on the pages read | Open source |
| Evidence | Vendor dashboards and audit trails | Signed receipts when configured, verifiable offline |
| Runs without the vendor | Varies: NeuralTrust documents a data plane that runs in your VPC or on-prem with a control plane in its cloud or yours; the other pages read do not document a vendor-free mode | Yes |
| Covers the whole estate | That is the pitch | Only what is routed through it |
How to use both
A platform for the estate and a firewall where a provable boundary matters. The two do not compete on the wire. The platform tells you what exists and how it is doing; the firewall reads traffic a specific agent routes through it and can emit signed receipts when configured. Teams that need a receipt an outsider can verify can put the firewall on those hosts alongside other controls.
