Head-to-Head
Nudge vs. Obsidian
Nudge spots new app sign-ups from email signal. Obsidian shows your SOC what's happening inside the apps your business actually runs on.
Nudge tells you about new sign-ups and OAuth grants. Obsidian shows your SOC what's happening inside the apps you've already sanctioned: identity, activity, integrations, and data movement.
Nudge surfaces apps and engages users. Obsidian's detections run continuously inside sanctioned apps, tuned on 500+ real SaaS incident response engagements, catching session abuse, OAuth misuse, and identity threats at runtime.
Nudge alerts on supply chain events via email. Obsidian traces blast radius across identity, activity, and integrations in one platform, so the SOC closes the incident in one place.
Nudge Security uses email as a primary signal source to discover SaaS and AI sign-ups, automate onboarding and offboarding workflows, and steer users toward sanctioned alternatives. It's lightweight, fast to deploy, and effective for IT-hygiene and shadow SaaS rationalization programs. In March 2026, Nudge added AI agent discovery in early access, extending the same model to agents built in enterprise SaaS platforms. The architecture is anchored in email signal and user engagement workflows.
Obsidian's Knowledge Graph ties identity, permissions, token grants, integrations, and activity together across every connected application. When a third-party vendor is compromised, Obsidian doesn't wait for the disclosure. Network effects mean that signal is already flowing across every environment we protect.
The result is faster investigations, cleaner blast radius attribution, and remediation decisions backed by what actually happened, not what could have.

Nudge is a SaaS Discovery and User Engagement platform. Its center of gravity is finding new SaaS and AI usage, steering users toward sanctioned alternatives, and automating IT-hygiene workflows like onboarding and offboarding.
Obsidian secures SaaS and AI as one system. AI Security. SaaS Security. One platform that does both right. It combines SSPM, SaaS Supply Chain Resilience, AI Security Posture Management, and Identity Threat Detection and Response in a single platform, with the visibility, runtime protection, and continuous governance to act across every application, agent, and integration. Discovery is a starting point. Obsidian is where SaaS incidents close.
Why it matters
A new SaaS sign-up is the start of risk, not the end of it. Where Nudge tells you a tool exists, Obsidian tells your SOC what's happening inside it. The breach surface lives inside the apps your business already trusts. That's where Obsidian operates.
Because discovery is only the starting point. Obsidian gives security teams visibility into what’s happening inside the SaaS and AI apps their business actually runs on: identities, activity, integrations, data movement, and agent behavior. That’s how teams move from knowing a tool exists to detecting, investigating, and closing real SaaS incidents.
Yes. Obsidian discovers shadow SaaS and AI through direct integrations with 200+ apps plus browser telemetry, then layers identity, activity, integration, and policy context on top. Discovery is part of the platform, but the real value is what Obsidian does next: runtime detection, identity threat response, integration-risk investigation, and AI agent governance.
Obsidian’s detections run continuously against activity inside sanctioned SaaS apps, tuned on 500+ real SaaS incident response engagements. That means the SOC can see what was accessed, by whom, through which session, token, integration, or agent, and across which downstream systems.
Obsidian ties integrations to identity, activity, and data movement across connected apps. When a third-party app or integration is compromised, the SOC can trace which records were touched, which identities were affected, how access spread, and where the blast radius landed.
Obsidian secures AI agents as part of the broader SaaS control plane. Teams get agent discovery, runtime activity context, and policy enforcement over what agents can access and do inside business-critical apps.
