About Operant AI

Operant AI sells one platform covering Endpoints, Agents, MCPs, and AI applications. Operant AI describes its platform as discovering, detecting, and defending all AI, agents, and MCP in real time. Operant AI says many customers start with Endpoint Protector or Agent Protector and add MCP Gateway and AI Gatekeeper as their AI footprint expands. Operant AI says all plans include the full Operant platform and differ in depth, deployment options, and the level of partnership.^[5]

Endpoint Protector enforces AI trust boundaries on the laptop. Endpoint Protector discovers Shadow AI tools, coding agents, and MCP clients on employee devices. Endpoint Protector monitors agent loops and blocks prompt injection, data exfiltration, and malicious shell execution directly on the device. Operant AI's endpoint coverage provides governance and runtime detection for coding and coworking agents running on employee endpoints.^[5]

Agent Protector inventories all AI agents operating within an organization's infrastructure. Agent Protector covers managed agents deployed through official channels and unmanaged agents running in cloud environments, SaaS platforms, and development tools. Agent Protector blocks the action inline when an agent attempts to access resources outside its established patterns, escalate privileges, or exhibit signs of data exfiltration. Agent Protector analyzes agent behavior patterns to identify and prevent security threats before they execute. Agent Protector monitors behavior, detects threats, and blocks attacks from zero-click exploits to data exfiltration and rogue agents. Operant AI's cloud agent coverage provides runtime security for homegrown and cloud-native agents, with support for AWS and Azure.^[5][6]

Operant Semantic Firewall understands the intent behind every agent action and enforces an allow, block, or redact decision inline, in real time. Operant AI reads the meaning of every prompt, plan, tool call, command, and data payload before it executes. Operant Semantic Firewall holds an agent to its assigned purpose across the whole session, catching drift from manipulation or its own initiative. Operant Semantic Firewall enforces access by data sensitivity, honoring the classification labels governance tools already set. Operant AI can redact the sensitive part of an action and let the agent keep working within scope, instead of killing the workflow.^[7]

Operant AI provides visibility and controls for every MCP server, client, tool, and connection in an environment, with MCP registries, white list and black lists, and NHI access controls. Operant AI catalogs MCP tools and discovers AI agents in real time across all environments. Operant AI detects prompt injections, jailbreaks, tool poisoning, and unauthorized access patterns across all MCP client and server interactions in real time. Operant AI implements MCP trust zones with real-time blocking of untrusted servers and tools. Operant AI prevents leaks of sensitive data and intellectual property through flow blocking and automatic redaction. Operant AI enforces least privilege execution controls and detailed access permissions for MCP tool usage.^[8]

AI Gatekeeper detects and blocks unauthenticated and unauthorized AI behavior in real time. Operant AI's AI application coverage is an LLM gateway with native firewall, offering multi-provider routing, request inspection, and traffic security for every AI application. Operant AI's 3D Runtime Defense provides real-time security across every cluster and every cloud, from infra to APIs. Operant AI detects and prioritizes AI-specific risks such as prompt injection, LLM poisoning, model theft, and sensitive data leakage. Operant AI applies in-line auto-redaction and obfuscation of sensitive and PII data.^[5][9][10]

Operant API & Cloud Protector catches and blocks malicious traffic at ingress and egress. Operant AI protects internal and third party API interactions with K8s-native controls for protocol specific authentication, authorization, traffic rate limiting, and API to API microsegmentation. Woodpecker provides flexible and extensible red teaming frameworks for K8s, APIs, and AI models and agents, and enables multi-layer threat simulation across runtime, APIs, and LLM integrations. Woodpecker covers prompt injection, jailbreaks, model theft, sensitive data leakage, and more.^[11][12]

Operant AI describes deployment as a single step helm install with zero instrumentation and zero integrations. Operant starts in observe-only mode by default, and customers decide when and where to enable enforcement. Operant AI offers VPC, on-premise, and air-gapped deployments on the Enterprise plan. Operant AI says pricing scales with the breadth and depth of its customers' AI surface, including endpoints under management, agents in production, and the governance needed across MCPs and AI applications. Operant AI supports workloads from coding agents on employee laptops to cloud agents across any infra, including LLM apps, AI agents, MCP servers, microservices, APIs, and traditional environments. Operant AI covers SaaS agents including Glean, Salesforce Agentforce, and Microsoft Copilot.^{[5][9][11][12][13][14]}

About P0 Security

P0 Security sells runtime access control that preserves identity and context while enforcing authorization as sensitive actions are attempted. The P0 Runtime Access platform combines discovery of where privilege and access exist, control of access and actions at runtime and an audit trail of what happened. P0 Security gives visibility and control over what agents, users and machines can access and do, in one platform.^{[1][2][3][4][5]}

P0 Security describes a problem in which organizations have too much standing privilege, too many credentials and too little visibility into who can do what. P0 Security says AI agents are becoming active participants in enterprise systems: they authenticate, call APIs, execute commands and move data, often on behalf of a human, another agent or a machine. P0 Security states that security teams need to understand what has access, enforce policy across the full action chain and preserve the context needed to explain every decision and action.^[3][4][5]

P0 Security continuously identifies agents, users and machines, along with the privileges, access paths and relationships behind them. P0 Security surfaces standing access and risky connections. P0 Security can grant just-in-time privilege, deny unauthorized actions or require human approval. P0 Security provisions native access in the target based on the task the agent is working on, subject to policy. P0 applies time-bound, purpose-specific permissions based on the action being requested and the context around it. P0 Security can grant access only for the task at hand and revoke it automatically when the approval window or task ends.^[3][5]

P0 identifies whether a task was initiated by a human, a machine or an agent, and preserves that originator context alongside the acting agent. P0 preserves the originator, the acting agent and the delegation chain between them, so policy can evaluate the full identity behind the action instead of trusting the agent credential alone. P0 Security evaluates every agent action before execution based on identity, context and intent. P0 Security replaces static permissions and implicit trust with real-time, policy-driven authorization. A data layer in P0 Security maps all access back to the IdP-defined identity. P0 extends authorization across the full agent action chain, from the originating user through agents, tools and into the target system. P0 evaluates identity, tool access and permissions together at runtime instead of treating them as separate controls.^[1][3][6][7]

P0 Security tracks privilege drift, policy exceptions and access changes so teams can support audits, compliance and investigations.^[3]

P0 integrates with the identity, infrastructure, collaboration and target systems already in an environment, with SDKs and APIs for extending enforcement into custom applications and workflows. P0 Security provides an SDK that brings runtime authorization into MCP servers, using JWTs and IdP claims to map user identity to the tools, actions and resources users are allowed to access.^[3][5]

P0 Security says it has worked through agent access patterns with customers and design partners as they build and deploy agents in production and pre-production environments. In one pattern, a user asks an agent to inspect service account permissions, troubleshoot access or make an IAM change. In that pattern, P0 keeps the user and agent identities linked from the start, so the requester remains part of the authorization context. For actions that change permissions, P0 Security can check whether the user is on call, whether a matching ticket exists or whether some other approval condition has been met. In a reporting workflow, a Reporting Agent may receive a request, call a BigQuery Agent to retrieve data, then use that result to generate a report. P0 carries the context forward when the Reporting Agent delegates part of the work to a downstream agent. In the coding agent use case, P0 evaluates the specific action, target resource, engineer scope, agent capability and any required business context, such as a matching Jira ticket or approved change window. P0 grants short-lived access only to the resource and action in scope once a request is approved. In a headless SRE case, a PagerDuty incident or other approved trigger starts the workflow, and a registered workload launches the SRE agent without a person actively operating it. An AI security company used P0 to replace broad, standing developer access with just-in-time, policy-driven access across GCP, SSH and emergency workflows, while keeping Okta, PagerDuty, Slack and CLI workflows intact.^{[2][3][5][8][9][10][11][12][13]}
