Teleskope Launches on Slack Marketplace, Strengthening DSPM with Native Remediation
Teleskope, the agentic data security platform that resolves data exposure instead of just flagging it, announced Teleskope for Slack, a native integration now live on the Slack App Marketplace. The integration discovers, classifies, and remediates sensitive data across every message, file, canvas, and list, in real time and across content that existed in Slack before the integration was installed.

Slack has become core communication infrastructure for organizations of every size. Until now, security teams have had no native way to enforce data policy at the point a message or file is created inside it. Most tools built for Slack detect a problem and send an alert. None of them close the loop. Native Slack DLP, available only on Enterprise Grid, can tombstone content, but depends on manual policy authoring, has no machine-learning-driven classification, and has no way to scan what is already sitting in the platform.
Teleskope brings the same automated remediation to Slack that it applies everywhere else. Real-time detection, native enforcement, and a full audit trail, without an external ticketing loop or a separate console.
Detection, notification, and tombstoning all happen inside Slack itself, the same place the message was sent. Policies are not limited to a binary block or allow. A policy can tombstone content outright or notify the sender and require a business justification before the content is released, putting judgment back into the workflow instead of a hard stop.

Historical discovery scans messages, files, canvases, and lists that already existed in Slack before Teleskope was installed, not just risk created going forward.

Built for Security Teams, Invisible to Everyone Else
Ramp uses Teleskope across both Slack and Google Workspace, enforcing their policies in real time. When Ramp moved its data security workflows onto Teleskope, the transition required no retraining and no change to how employees used Slack day to day.
“The lift and shift were so seamless that users didn’t even realize we had changed platforms,” said a security leader at Ramp.
“I’ve been in the DLP space for a long time and tested a lot of providers. Teleskope is the latest and greatest. They built exactly what we needed, moved fast, and continue to deliver at Ramp’s pace,” the security leader added.
