The integrations page says Nagomi connects to the security tools in its customers' environments, and lists tool categories such as Identity and Access Management (IAM) and Cloud Security Posture Management (CSPM). The home page frames its offer as a move from exposure overload to autonomous control. The support policy ties support to a paid subscription.From its own pages, the company sells mainly to security teams that already run a cloud scanner, and it offers a page for each scanner it lists. One use case page addresses teams facing more criticals than any team can absorb. This is our reading of the pages, not a recommendation.

How they differ

CISO Tribune files both Nagomi Security and Tamnoon under Exposure prioritisation and CTEM as the primary category, and Tamnoon also under Managed security service providers. It also sells Agentic Exposure Operations, an operating model covering identity, attack surface, misconfigurations, and vulnerabilities. Nagomi connects to the EDR, identity, firewalls, and vulnerability tools its customers already own to build a single exposure picture.

Tamnoon sells Tami, its AI Cloud Security Agent, which enriches each alert with context. Tamnoon also sells an engine that investigates findings from existing scanners and runs remediations it has proven safe through the customer's own change process. Tamnoon builds remediation workflows in Jira and Microsoft Teams, and creates tickets in ServiceNow. One media enterprise used Tamnoon's managed cloud security service to move from Check Point CloudGuard to Wiz.

Both companies work on top of tools customers already run, but they describe the work differently: Nagomi Security describes agents that select a path and validate the close, while Tamnoon describes an engine that declines findings it cannot prove safe. Nagomi Security is privately held, and Tamnoon was established in 2021 with investors that include cybersecurity industry experts and angel investors. On March 19, 2026, Nagomi Security announced Agentic Exposure Ops, and on September 30, 2026, it announced a partnership and native integration with Recorded Future.

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.

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]
