- Shadow IT & Shadow AI detection — surface every third-party app, OAuth grant, and AI tool connected to your core systems, sanctioned or not.
- OAuth risky vendors detection — match every discovered OAuth grant against a database of 3,000+ vendors and score the vendor itself, not just the app.
- SaaS access reviews — a continuous, always-current view of who has access to what, so certifications stop being a spreadsheet fire drill.
- Cross-system sync — automatically enforce the access decisions you make, replicating users and groups across your SaaS stack in real time.
Why SaaS needs a different kind of IGA
Modern organizations run an average of 110 SaaS applications, and companies estimate that roughly 70% of the business apps they use today are SaaS (per Statista). Most of those apps were never chosen by IT — they were signed up for with a company email and an OAuth click. Legacy IGA platforms (SailPoint, Saviynt, and similar) were built for on-prem directories and enterprise SSO/SCIM integrations. That model breaks down for SaaS sprawl for two reasons:- Visibility gaps. If an app isn’t connected to your IdP, it’s invisible to traditional IGA — that’s exactly where Shadow IT and Shadow AI live.
- Cost. Native user/group sync (SCIM) is usually locked behind Enterprise-tier SaaS plans that cost 2.5x more on average than Pro/Team plans.
Shadow IT & Shadow AI detection
You can’t govern access to an app you don’t know exists. Synk.to uses the Admin API access you already grant it on systems like Google Workspace, Microsoft Entra ID, and Microsoft 365 to enumerate:- Every third-party OAuth grant connected to your core identity providers — not just the apps IT provisioned.
- AI tools and agents employees have authorized with company credentials, including copilots, browser extensions, and autonomous agents with standing OAuth access to email, drive, or chat data.
- Self-issued integrations such as Google Apps Script projects, which function as OAuth apps employees create for themselves and that rarely show up in a standard app inventory.
OAuth risky vendors detection
Knowing an app is connected isn’t the same as knowing whether the company behind it can be trusted with your data. Synk.to matches every discovered OAuth grant against a database of 3,000+ vendors, using stable OAuth client/app IDs — and vendor or product name matching as a fallback — to resolve a discovered app to the company that built it. Each vendor record carries:- Company details — site, employee size, country, founding year, public/private status, and funding stage.
- Compliance & trust posture — certifications (SOC 2, ISO 27001/27701/42001, FedRAMP, HIPAA, PCI DSS, CSA STAR, HITRUST), privacy policy, DPA, trust center, bug bounty, status page, SLA uptime, data residency, and SSO/SAML or SCIM support.
- Products & OAuth apps — every product a vendor ships, each with its own catalog of OAuth client/app IDs, so a discovered grant resolves to the exact product, not just the parent company.
SaaS access reviews
Discovery tells you what’s connected. Access reviews tell you whether the access it holds is still appropriate — the core question of identity governance: should this access exist at all? Synk.to turns access reviews from a periodic, manual export-and-compare exercise into a continuous process:- Centralized visibility into user and group entitlements across every connected SaaS system, in one table.
- Drift and risk detection — over-privileged users, orphaned accounts, and admin rights left behind by former contractors or employees.
- Audit-ready reporting for SOC 2, ISO 27001, HIPAA, and similar frameworks, without stitching together spreadsheets from each app.
- License rationalization by surfacing accounts and seats nobody is using anymore.
User Access Reviews
Read the full breakdown of how Synk.to elevates access reviews for SaaS-heavy organizations.
Getting started
To start using Synk.to, you need to connect Google Workspace or Entra ID — your core identity provider is what powers Shadow IT/Shadow AI detection, access reviews, and sync:
To get started, Synk.to only needs read-only permissions on your identity provider — enough to power Shadow IT/Shadow AI detection and access reviews while keeping exposure and risk to a minimum. Read-write access is only needed later, if you want Synk.to to enforce access changes automatically.
From findings to enforcement: how Synk.to connects to your systems
Detection and reviews surface what needs to change. Synk.to’s sync engine is what actually closes the loop — enforcing access decisions across your stack instead of leaving them as a report. Synk.to connects to each SaaS system using its regular Admin API — the same API used for detection — which typically manages users and groups without requiring an Enterprise plan. To connect a system, you provide a limited API key or OAuth access, at one of two levels:- Read-write access to groups, read-only access to users. Synk.to can keep group membership in sync across systems, but won’t create, suspend, or delete user accounts.
- Read-write access to both groups and users (recommended). This unlocks the full platform — Synk.to can automatically provision new users across your SaaS stack, deprovision or suspend users who leave, and keep user info updated as it changes.
