About Neo

Neo sells security for AI and agentic software across every endpoint, SaaS app, and cloud service. Neo sees every AI agent, app, extension, skill, and MCP server on devices, in browsers, and across SaaS apps and cloud, checks its configuration, and enforces policy before any action runs. Neo maps an organization's teams, people, endpoints, agents, MCP servers, skills, and everything they reach.[2][4][5]

Neo addresses a situation in which few teams can say which agents run on their fleet, what each one can reach, or what it did yesterday. Neo describes agents as acting with the employee's own access, so that most tools see the employee. Neo describes code, keys, and customer data reaching AI through prompts, pastes, uploads, and agent reads, with some tools training on what they receive. Neo describes MCP servers, skills, subagents, plugins, and extensions as arriving faster than anyone can review them, with already approved apps shipping new AI features without a review.[5]

Neo Node enforces policy on the laptop, on macOS, Windows, and Linux. Neo Node deploys through the MDM a customer already runs, with no kernel module and no reboot, and decides each agent action with allow, ask, or block. Neo works as a layer inside the tool, in user land with no kernel component, where Neo sees the agent's actions and decides before they run. Inside Claude Code, Neo Node reads the model, MCP servers, skills and plugins that Claude Code loads. Neo Node reads the whole session rather than only the command. On managed endpoints, the hooks of Neo keep running if switched off and come back if deleted. Neo enforces before the action runs, at the tool call in tools with a Neo connector and at launch for the rest.[5][6]

Neo Console starts from a customer's organization and its teams, taken from the identity provider. Neo Console finds settings that give an agent more reach than its work needs. Neo inventories every AI app, agent, and MCP server on each device, scopes what each can touch, and decides each action before it runs. Neo inventories every AI tool and model on devices, browsers, and SaaS, sanctioned or not, with owner, version, and publisher. Neo checks each tool's setup and version and flags drift from a customer's baseline. Neo decides every prompt, tool call, file access, and network request on the device before it runs.[4][5][6]

Neoverse is the intelligence layer for AI apps and tools, and Neoverse is publicly available. Neoverse checks every extension, package, skill, and MCP server before it runs, and Neo blocks a hijacked or malicious release fleet-wide. Neoverse rates an unsigned server loaded by an agent as Unsafe on first sight. Neoverse rates as Malicious an MCP server that copies session memory to an outside store its listing never names, and Neo blocks it by policy when the agent loads it. Neo inspects data on the device before it reaches an AI tool, stops it or points the person to the approved tool, and flags tools set to train on a customer's data.[5][6]

Neo covers ChatGPT, Claude, Gemini, Copilot, Salesforce, and every other AI app that teams sign into, with work and personal accounts kept separate. Amazon Bedrock, Cursor Cloud, GitHub Actions, and n8n sit under the same policy as the laptop. A single killswitch in Neo ends every active AI agent session in the estate, and no new session can start until the switch is lifted. Neo can end every session, running or new, the moment several agents break from normal behavior at once. Neo follows the agent inside each tool on the endpoint and into the SaaS apps and cloud deployments it acts through, with one product and one policy for all AI security and control.[1][4][5][6]
