Nudge Security is a shadow-IT discovery product with AI added as one of many categories. GreyScape.ai is AI-native — shadow AI discovery, AI spend control, EU AI Act compliance, approved-models policy, and a tamper-evident audit log built around the AI use case from day one. For the AI-specific problems mid-market companies face this quarter, GreyScape is the cleaner answer.
Pick GreyScape.ai if…
AI is your urgent surface — EU AI Act enforcement in 53 days, AI spend climbing 20-30% month over month, ChatGPT Enterprise vs personal-card Plus, and approval/budget workflows you need running this week. You want discovery + spend + compliance + approved-models policy in one tool, self-serve at $3/user/month, with a 14-day refund and no procurement cycle.
Pick Nudge Security if…
Your immediate problem is non-AI SaaS sprawl — hundreds of CRM, marketing, and OAuth-grant signups across business units that need broad inventory and identity-grant governance, with AI as a relatively minor slice of the surface.
Run GreyScape as your AI platform
If you're already running a shadow-IT platform like Nudge for the broader SaaS surface, GreyScape.ai layers on top for the AI-specific work — AI spend, EU AI Act register, approved-models policy, AI-vendor billing reconciliation. The data we collect doesn't overlap with theirs; the AI workflows are ours alone.

AI-native discovery, end to end
Browser extension catching Cursor, Claude.ai, Perplexity, midjourney.com and the niche tools nobody emails a signup for. Card-feed and receipt parsing that picks up ChatGPT Plus expensed on a personal card. Direct billing connections to OpenAI, Anthropic, and GitHub. The first week with GreyScape you typically uncover 3-5 AI vendors you didn't know existed — Nudge's email-based discovery misses most of those.
AI spend control that pays for itself
Per-user, per-vendor, per-token attribution. Org/team/project budgets with soft alerts at 75% and hard caps at 100%. Anomaly detection flags a runaway loop before EOM. Nudge doesn't track AI spend at all. If your AI bill grew 8× in 4 months, this is the capability that earns the seat.
EU AI Act compliance shipped, not on a roadmap
Per-system risk classification against Annex III. Obligation catalogue mapped to Articles 4, 9-17, 26, 27, 49, 50, 71, 73. Evidence vault with file uploads. FRIA template. Article 50 transparency triggers. One-click audit pack export for market-surveillance authorities. With enforcement in 53 days, this is the only working operational layer in this category.
Approved-models policy + provisioning
Org-wide allowlist of which AI models (GPT-4 family, Claude Sonnet/Opus, Gemini, local Llama) employees can use. Approval workflow auto-issues service-account keys on approval. Nudge surfaces accounts that exist; we close the loop on policy + provisioning.
Tamper-evident audit log + SIEM forwarding
Wave 8.5 shipped a cryptographically chained audit log — SHA-256 chain over each row via a Postgres trigger, with structural verification. Plus a webhook-style SIEM forwarder covering Splunk HEC, Sentinel, Elastic, Datadog, and LogScale. Defensible evidence story for ISO 42001 and EU AI Act Article 12. Nudge's audit story is logs, not chained evidence.
Self-serve at a real price, with a refund
$3/user/month, published, self-serve signup, 14-day money-back. For a 100-seat team that's $3,600/year. Nudge is enterprise-quoted with multi-week procurement cycles — fine at 500+ seats, but adds 4-12 weeks of delay for mid-market buyers who need shadow AI under control now.
Narrow scenarios where the honest recommendation is them, not us. For the typical mid-market buyer wrestling with shadow AI, EU AI Act, and AI spend in one quarter, GreyScape.ai is the cleaner answer.
Broad non-AI SaaS coverage
Nudge has years of fingerprints across thousands of non-AI SaaS tools — CRM, design, productivity, dev tools. If your goal is inventorying the long tail of generic SaaS your team signed up for outside IT, that breadth is real. We're deliberately AI-focused.
OAuth grant inventory
Nudge surfaces third-party OAuth grants attached to SaaS accounts and helps revoke high-risk ones. It's a useful identity-side capability outside our AI scope.
Bottom line
Nudge Security is a competent shadow-IT product. GreyScape.ai is the AI-native platform built for the urgent AI problems you actually have this quarter — EU AI Act enforcement, AI spend sprawl, ChatGPT-on-personal-cards, approval workflows. For the mid-market buyer choosing one tool to solve AI governance end to end, the answer is GreyScape.
Yes, for any company whose urgent problem is AI specifically. GreyScape.ai is AI-native — discovery, spend, EU AI Act compliance, approved-models policy, audit trail — built for the AI use case end to end. Nudge is a shadow-IT product that bolted AI on as one of many categories. If AI is what's keeping you up at night, GreyScape is the cleaner pick.
No. Nudge surfaces SaaS sign-ups via email logs but doesn't parse AI-vendor billing, attribute spend to users, track per-token cost, or enforce budgets. GreyScape.ai ships all of it, plus anomaly detection that catches a runaway prompt loop before EOM.
Nudge has no dedicated EU AI Act module as of June 2026. GreyScape.ai ships a working compliance layer: per-system risk register against Annex III, obligation catalogue mapped to the Articles that matter (4, 9-17, 26, 27, 49, 50, 71, 73), evidence vault, FRIA template, Article 50 transparency triggers, and a one-click audit pack export.
GreyScape.ai is $3/user/month on Standard, published on the pricing page, self-serve, with a 14-day refund. Nudge is enterprise-quoted with no public price; reports suggest annual contracts starting in the low five figures. For a 100-seat mid-market team, GreyScape is about $3,600/year; Nudge typically runs $25k-50k.
Five minutes from sign-up to a working dashboard with the demo workspace pre-seeded. Connect your AI-vendor billing accounts (OpenAI, Anthropic, GitHub) in another 10 minutes, and you're live on your real data. Nudge requires a sales motion, security review, and contract — typically 4-12 weeks.
Yes — GreyScape.ai is your AI platform, Nudge is your broader shadow-IT platform if you need that surface separately. The data we collect doesn't overlap; the AI workflows (spend, EU AI Act, approved-models) only exist on our side.
The demo workspace has seeded data — shadow AI findings, AI spend, budget alerts, compliance register — so you can click through GreyScape.ai in 5 minutes and decide.
