Revoke Inappropriate Data Sharing

Securing data for the world’s most innovative organizations

Problem

Hidden access creates invisible risk

Traditional security approaches can't address today's document sharing or collaboration challenges:

Majority of organizations have files accidentally shared with everyone on the internet

IT teams spend 12+ hours weekly manually fixing permissions issues

Employees routinely share sensitive documents with unmanaged personal accounts

No visibility exists into critical documents shared with former employees or vendors

Without comprehensive access governance, your intellectual property remains exposed to unauthorized access.

Solution overview

There’s an easier, more scalable way to stop secrets sprawl.

Audit document permissions

Remove historical exposure at scale and use automation for future enforcement. Maintain real-time visibility into document sharing changes with instant alerts for high-risk activities. Prevent access sprawl before it creates security vulnerabilities. .

Data access remediation

Instantly identify inappropriate sharing across SaaS apps and remediate access issues at scale. Fix thousands of risky document permissions with just a few clicks and set up tailored policies to automate remediation.

Secure collaboration platforms

From public GitHub repos to Slack connect channels, Confluence spaces to Salesforce records and more - uncover blind spots across your SaaS apps. Combine deep historical audits with continuous real-time monitoring for inappropriate data sharing.

Automated employee offboarding protection

Eliminate residual access risks from incomplete offboarding processes. Automatically identify and revoke document access for departed employees. Instant visibility into every document with a public or company link and shared with personal email accounts.

External sharing control

Prevent data leaks by monitoring and managing document access for vendors, contractors, and other external parties. Automatically revoke access when collaborations end.

Your digital perimeter is porous and permission chaos reigns

Every day, sensitive documents are shared with personal accounts, ex-employees, and even the open internet while legacy tools remain blind to this exposure. The average organization has thousands of inappropriately shared documents creating invisible risk vectors that remain undetected until it's too late.

Nightfall offers a smarter, more scalable solution

Enhanced accuracy

Nightfall’s industry-leading GenAI detection engine pinpoints PII, PCI, PHI, secrets, and credentials with fewer false positive alerts.

Unparalleled visibility

Monitor sharing and permissions settings across SaaS apps to identify risks in real time.

Automated workflows

Security teams can maintain a secure SaaS environment and ensure continuous compliance by responding to security issues the instant they pop up.

SaaS security posture

Nightfall leverages generative AI (GenAI) for a dynamic and responsive management approach to your SaaS security posture.

Monitor download events across SaaS apps and endpoints

Detect download events and uploads to unsanctioned locations in real time.

Set alert thresholds based on the number of downloads that occur in a certain time frame (e.g. “10 downloads in 24 hours”).

Reduce noise by tailoring policies according to:

High-risk users, such as departing employees

High-risk content, such as specific files, folders, or drives

High-risk data types, such as PII, PCI, PHI, secrets, or credentials

Get actionable alerts or respond in the Nightfall console

Configure alerts to Slack, Teams, Jira, email, or your SIEM of choice.

Review rich metadata for relevant users and content in the Nightfall console, including recent activity logs.

Take immediate action by suspending user access to SaaS environments.

Send custom messages to educate employees about policy violations either in-app or via Slack, Teams, or email.

How It Works

Comprehensive historical audit

Instantly discover all document permissions, sensitive information in public channels or repositories across your SaaS apps. Identify every inappropriately shared file, external collaborator, and risky user within hours of deployment - not the months required by traditional tools.

Create granular audits by selecting exact criteria: date ranges, file age, specific app locations, permission settings, users, and more. Get complete visibility with full context of permission changes in the console

Real-time monitoring

Detect inappropriate sharing the moment it happens with continuous monitoring that catches risky behavior before data leaves your control. Automatic alerts flag high-risk sharing patterns without overwhelming your team.

Schedule delayed remediation actions to execute after minutes, hours, days or weeks - allowing legitimate collaboration then automatically revoking access when work completes.

Automated, bulk remediation

Apply tailored policies to high-risk users or groups synchronized from Okta, Entra ID, or Google Directory. Create specialized rules for departing employees that maintain productivity before offboarding.

Fix thousands of permission issues with a few clicks. Automatically change public links to private, revoke ex-employee or external partner access, or update sharing settings across your entire shared drives in seconds instead of weeks of manual work.

AI-powered risk scoring and human firewall

Our risk-scoring assesses context - identifying documents in public locations as higher risk than those in private locations as one of the many heuristics - prioritizing your most critical exposures.

When users share with external accounts, prompt them to provide business justification, creating accountability and awareness.

Frictionless deployment

Secure your sensitive assets within a day - not months. API-based integration with SaaS apps to get started in minutes. Protect Google Workspace, Microsoft 365, Slack, and more without disrupting users.
