What it sells: Nagomi Security

What AI Exposure Eliminators does[3][4]
AI Exposure Eliminators run investigations against live environment changes once the unified exposure picture is built. The agents run the full investigation, pick the neutralization path, route the work, and validate the close without prompting. Eliminators check reachability, evaluate existing controls, and chain what attackers would chain.
What Agentic Exposure Operations does[3][5]
Agentic Exposure Operations closes exposure at the root. It continuously investigates, catches, neutralizes, and validates the close across identity, attack surface, misconfigurations, and vulnerabilities. Nagomi automatically investigates, neutralizes, and validates every close.

What it sells: Nucleus Security

What Nucleus Data Core does[5]
The Nucleus Data Core is a system of record for assets, exposures, and threats. The Nucleus Data Core transforms fragmented data into unified, live exposure context. Nucleus says every AI decision and action is grounded in the Nucleus Data Core.
What Nucleus ServiceNow App connector does[7]
The Nucleus ServiceNow App connector integrates directly with ServiceNow through the Nucleus Security for Vulnerability Response app. The app runs directly on a customer's ServiceNow environment and enables integration with Vulnerability Response. The app has several different integrations, including assets and vulnerable items.

About Nagomi Security

Nagomi Security sells a platform that turns the tools its customers already own into a coordinated defense. Nagomi states its mission as preventing the preventable breach. Nagomi says security teams have a coordination problem rather than a tool problem. Nagomi says vulnerability scanners flag what is broken, EDRs see what is running, and configuration tools manage what is deployed.[5]

Nagomi began with the question of whether security controls are actually working. Nagomi's work started as automated security controls assessment and grew into a full operating model for how security teams detect, investigate, remediate, and verify exposure. Nagomi calls that operating model Exposure Ops.[5]

Nagomi's agents proactively hunt the exposure paths adversaries would actually exploit and surface why it matters, what changed, and how to close it. Customers authorize one-click fixes, and the agents select the path to neutralize each exposure: hardening configs, deploying controls, or patching when ready. Nagomi's agent continuously verifies that fixes hold from the sensor itself, not from a ticket status.[3]

Eliminators check reachability, evaluate existing controls, and chain what attackers would chain. A team of specialists handles triage, enrichment, correlation, and validation in coordination. When new attacker behavior appears in the wild, Eliminators test it against the customer's environment, controls and chains.[3]

Nagomi's agents run the full investigation, pick the neutralization path, route the work, and validate the close without prompting. Customers review the case and approve the action. Nagomi connects to the EDR, identity, firewalls, and vulnerability tools its customers already own to build a single, correlated exposure picture. Nagomi says standalone RBVM and CAASM consoles collapse into one agentic operating model.[3]

Nagomi connects via read-only APIs, so there are no software agents to deploy on endpoints. Agentic Exposure Operations closes exposure at the root. Across identity, attack surface, misconfigurations, and vulnerabilities, Agentic Exposure Operations continuously investigates, catches, neutralizes, and validates the close. Nagomi automatically investigates, neutralizes, and validates every close.[1][3][5][7][8][9]
