Security Risks of Collaboration Tools Like Teams, Zoom and Slack
SECURITY RISKS OF COLLABORATION TOOLS LIKE TEAMS, ZOOM AND SLACK
Teams, Zoom, Slack and shared files make work easier and leak data when set up loosely. Here are the risks and the settings that fix them.
Teams, Zoom, Slack, SharePoint and Google Drive hold more of your business than email does now. Chats, client files and meeting recordings all live there. Loose settings turn them into easy targets.
The common risks
- Oversharing. "Anyone with the link" sharing that never expires.
- Guest sprawl. Outside users who still have access long after a project ends.
- Phishing in chat. Attackers now send malicious links and fake help desk messages through Teams chat.
- Unmanaged devices. Staff opening client files on personal phones and home PCs.
- Recordings and transcripts. Meetings capture sensitive details and get stored indefinitely.
- Shadow apps. Free tools staff sign up for without IT knowing.
The fixes
- Set sharing defaults to people inside your organization, with link expiration for outside shares.
- Review guest accounts every quarter.
- Block external chat from unknown domains unless you need it.
- Require MFA and use Intune to control which devices can open company data.
- Set retention rules for recordings.
We handle these settings in Microsoft 365 and Google Workspace, and set up Teams Phone and conference rooms with security in mind from day one.
