SaaS security
Protect your SaaS applications
Expel integrates directly with apps like GSuite, Slack, and GitHub and monitors activity 24x7 to stop risky user behavior, data exposure, or sneaky configuration changes.
Our difference
See what’s happening in your SaaS applications
Our detection strategy results in secure SaaS applications by focusing on suspicious user activity and giving you a clear view of real risks.
Monitor suspicious user activity
We look for the human element—unusual logins, sketchy data downloads, or unauthorized access—to spot threats that others might miss.
Detect suspicious changes
We track admin setting changes, new privileged accounts, and unexpected external data sharing to keep your critical SaaS applications locked down.
Cover key MITRE ATT&CK tactics
Get coverage for initial access, persistence, privilege escalation, and credential access using your existing SaaS authentication and admin logs.
Expel MDR
Our approach to SaaS security
Expel watches your cloud-based apps like Google Workspace, Dropbox, and Slack to protect sensitive data. Our approach provides critical visibility into how that data is used and focuses on detecting behaviors that signal data exfiltration, such as unusual login patterns, excessive downloads of Personally Identifiable Information (PII), or unauthorized access to sensitive files. When a threat is detected, we provide context-rich alerts and can automatically take action, like disabling a user account, to shut it down fast.
MDR Benefits
Why Expel for SaaS security?
It’s not just about finding SaaS security threats. It’s about making your entire security program stronger, starting with the apps your organization uses every day.
Get more from your SaaS security
We don’t rely on out-of-the-box vendor alerts. We integrate directly with your SaaS applications to build high-fidelity detections that find what others miss.
Context that helps you act faster
Alerts are automatically enriched with user roles, location, and other metadata, giving analysts the full picture to triage alerts from any source.
Keep your code secure
We monitor code repositories like GitHub for suspicious changes and risky user activity to protect your developers’ workflows.
See the signal, not the noise
Our advanced detection engine and analytics means your team spends less time on phantom threats and more time on what matters.
Connect SaaS activity to other threats
SaaS signals support investigations across identity or insider risk scenarios, connecting risky behaviors to the big picture across your tech stack.
Continuously updated detection logic
We author hundreds of user authentication detections and add more regularly, so our analytics are always current with the latest attacker techniques.

Frequently asked questions
SaaS applications store sensitive data and are accessed via the internet with identities as the primary control plane. Attackers target SaaS to exfiltrate data, abuse OAuth tokens, and establish persistence. Perimeter-based security tools don’t monitor SaaS activity, so dedicated detection and response is required.
Expel integrates directly with apps like GSuite, Slack, Box, Workday, Salesforce, GitLab, and GitHub and monitors activity 24×7 to stop risky user behavior, data exposure, or configuration changes. We provide visibility into data usage by detecting exfiltration behaviors like unusual logins, excessive PII downloads, or unauthorized sensitive file access. Detected threats trigger context-rich alerts and rapid, automated containment, such as disabling user accounts.
Attackers use OAuth to grant persistent access to SaaS applications without needing passwords. Expel monitors for suspicious OAuth application grants, including third-party apps requesting broad permissions and access tokens issued outside normal patterns. When confirmed malicious, we can revoke the OAuth grant immediately.
A CASB enforces access policies and provides visibility into SaaS usage. Expel’s SaaS security goes further by actively monitoring SaaS behavioral signals through direct integrations for indicators of compromise, investigating anomalies, and responding to confirmed threats. CASB is a control. Expel is the detection and response layer covering what happens when controls are bypassed.
