# Details
Slack workspaces grow in unexpected ways once departments start creating their own channels, guests get added for vendor collaborations, and Connect channels link external partners to internal conversations. With Pro plans at $8.75 per active user monthly and Business+ tiers at $15, unmanaged seat counts translate directly to budget overruns that compound each billing cycle. Access reviews confirm that only current employees hold active Slack accounts, that guest permissions stay limited to appropriate channels, and that admin roles remain assigned to people who genuinely need workspace control.

Governing Slack access involves challenges that extend well beyond basic seat counts and login tracking. The platform offers granular controls including workspace roles, channel-level permissions, guest restrictions, and Connect channel access for external organizations. A former contractor might retain guest access to sensitive project channels months after their engagement ended. A departed employee could still have admin permissions on workspace settings nobody remembered to audit. Slack provides member lists, role assignments, and activity data through its admin dashboard and APIs, but correlating this data with HR records and manager input requires manual effort that rarely happens consistently.

Third-party tools address this gap through SCIM integration, SSO authentication patterns, or direct API connections. Some pull user lists, roles, guest accounts, and channel memberships directly from Slack for automated certification workflows. Others detect Slack usage through identity provider data without application-level visibility into specific channel permissions. This article examines eight platforms worth considering for Slack access reviews in 2026, covering how each handles discovery, review workflows, and compliance documentation.

## Torii

Torii [https://www.toriihq.com] connects to Slack through its native integration, pulling employee names, email addresses, job titles, departments, user status, license assignments, license types, and historical usage patterns. This visibility extends beyond simple login data to show which employees actively participate in channels versus those holding seats they no longer use. The platform combines SaaS management with identity governance in a unified interface, making it possible to run access certifications while tracking spend and identifying license optimization opportunities.

Torii approaches Slack access reviews through automation and contextual intelligence. AI flags accounts that appear anomalous based on peer group analysis, surfaces inactive users who might be candidates for license reclamation, and routes certification requests to the appropriate managers without manual intervention. Reviewers can approve or deny access directly from Slack notifications themselves, and remediation actions flow back to Slack automatically when integration permissions allow deprovisioning.

Slack-specific fields available through Torii include employee name, email, title, department, user status, license status, license types, and historical usage by employee. Guest accounts and external collaborators appear alongside regular workspace members, providing complete visibility for access reviews that need to cover both internal employees and outside parties.

Pros:
- Deep Slack integration surfaces user status, license types, and historical usage patterns that SSO-only connections miss entirely
- AI-powered anomaly detection identifies over-privileged accounts and flags access patterns that deviate from peer group norms
- Combined SaaS management and identity governance eliminates the need for separate tools to track spend and run certifications
- Slack notifications let reviewers complete access certifications without switching contexts or logging into another dashboard

Cons:
- Pricing positions Torii as an enterprise solution that may exceed budgets for smaller organizations with straightforward access review needs
- Cloud-focused architecture means organizations seeking on-premise deployment will need to look elsewhere

## Nudge Security

Nudge Security discovers Slack accounts through a fundamentally different approach than most governance platforms. Rather than requiring connectors or browser extensions, the platform monitors email confirmations and account creation messages to build a complete inventory of who signed up for Slack workspaces and when. This catches accounts created outside official IT channels, including trial workspaces that employees spun up before the company standardized on Slack Enterprise Grid.

The Nudge Security [https://www.nudgesecurity.com/] access review workflow uses behavioral prompts rather than mandatory enforcement. When the platform identifies Slack accounts needing review, it sends nudges via Slack itself or email asking users to confirm whether they still need access. This approach achieves an 83% compliance rate according to the company, compared to roughly 32% for traditional blocking methods. The platform also tracks authentication methods for each Slack account, showing whether users log in through SSO, OAuth, or direct credentials.

For quarterly Slack access audits, Nudge Security compresses what typically takes one to two weeks into a few days of focused work. The User Access Review Playbook automatically categorizes accounts and creates compliance groupings, while auditor-ready reports document all actions taken during the certification cycle. Supply chain breach alerts notify security teams when Slack or connected apps experience security incidents.

Pros:
- Email-based discovery finds Slack accounts that connector-dependent tools miss, including shadow workspaces and trial accounts created before official procurement
- Full SaaS inventory becomes available in approximately 75 minutes without agents or browser extensions required
- Offboarding Playbook identifies all Slack access for departing employees, eliminating manual effort to find abandoned accounts

Cons:
- Behavioral nudges guide rather than enforce, meaning users can ignore prompts if organizational culture does not support compliance
- Requires Google Workspace or Microsoft 365 for email-based discovery to function properly
- Cannot provision or deprovision Slack accounts directly since the platform focuses on discovery and behavioral engagement

## Zluri

Zluri [https://www.zluri.com/] connects to Slack through its 300+ pre-built connectors, pulling user data alongside entitlements from across the SaaS stack. The platform uses what the company calls a patented nine-method discovery engine that provides visibility beyond SSO-managed accounts to include local accounts, external collaborators, and guest users that might escape identity provider detection. For Slack specifically, this means seeing guest accounts and Connect channel participants alongside regular workspace members.

Access reviews in Zluri support multiple reviewer levels with automated workflow progression between stages. When a first-level manager approves Slack access, the certification automatically routes to a second-level reviewer if organizational policy requires it. Automated reminders prevent delays, while bulk approval capabilities let reviewers process low-risk accounts quickly. Users report reducing full-day audit processes to roughly 30 minutes once workflows stabilize.

The platform flags orphaned accounts, over-privileged users, and external accounts with excessive access through AI-powered risk identification. Customizable inactivity thresholds help identify dormant Slack accounts that could be downgraded to free tier or removed entirely. Closed-loop remediation means reviewers can deprovision users directly from the certification interface when Zluri has sufficient API permissions.

Pros:
- Multi-level reviewer support handles complex approval chains where Slack access decisions require sign-off from multiple stakeholders
- AI-powered risk identification automatically flags orphaned accounts and external users with excessive workspace permissions
- Users report reducing quarterly audit processes from full days to under an hour once certification workflows are configured

Cons:
- Some niche applications lack native integrations, though Zluri works to enable custom connector development upon request
- Reporting customization options feel limited when stakeholders need specific data cuts not covered by default templates
- Workflow editor navigation can be confusing without clear labeling for complex multi-stage certifications
