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.
Nudge is built for discovery and IT-hygiene programs: finding shadow SaaS sign-ups, automating onboarding and offboarding workflows, steering users toward sanctioned alternatives. If your program ends at finding what's there, Nudge is built for that scope. The gap is what happens after discovery. When a session is hijacked inside Salesforce, when an OAuth token is being abused against your data, when an integration is compromised and exfiltrating records, discovery alone doesn't catch any of it. Obsidian closes that gap: continuous activity from inside 200+ sanctioned apps, behavioral detections tuned on 500+ real SaaS incident response engagements, and identity, activity, and integrations tied together so the SOC can detect, investigate, and close incidents in one platform.
Yes. Obsidian discovers shadow SaaS and AI through direct integration with 200+ apps plus browser telemetry, then layers activity, identity, and integration context on top. Discovery is one of multiple capabilities the platform delivers, alongside runtime threat detection, identity threat response, integration-risk investigation, and AI agent governance. More on our telemetry sources.
Nudge alerts customers about vendor breach events through email when its signal sources surface them. Obsidian's detections run continuously against activity inside sanctioned apps, tuned on 500+ real SaaS incident response engagements. The difference shows up in incident reconstruction: an email alert tells you something happened; Obsidian tells you what was accessed, by whom, and across which downstream systems.
Obsidian traces each integration to identity, activity, and data movement across the connected apps. When a third-party integration is compromised, the SOC sees which records the integration touched, which identities were affected, and how access spread. Nudge surfaces inventory and alerts; Obsidian traces blast radius.
Nudge added AI agent discovery in early access in March 2026, extending its email-signal model to agents built inside enterprise SaaS platforms. Obsidian goes further: agent discovery plus runtime activity context, plus policy enforcement on what agents access and do inside the apps. The depth of inside-the-app context is the differentiator.
Nudge's strength is discovery and user engagement. Buyers running shadow SaaS rationalization, automated onboarding/offboarding, and end-user behavior workflows have described Nudge as a strong fit, including one prospect who called it “very unique in the market” for that scope. If your program ends at discovery and user steering, that's real value. Where the program needs to extend, into runtime threat detection, integration-risk investigation, identity threat response, and AI agent runtime governance, that's where Obsidian is built to operate.
