Teleskope has launched a native Slack integration on the Slack App Marketplace, bringing its data security posture management and data loss prevention controls into Slack Enterprise Grid.
The pitch is aimed at security teams with a familiar problem: Slack is where employees move fast, paste too much, attach the wrong file and occasionally turn a compliance program into a chat thread. Teleskope for Slack is designed to detect, classify and remediate sensitive data across messages, files, canvases and lists, including content already sitting in Slack before the integration is installed.
Teleskope said the integration handles detection and remediation in under two seconds under a guaranteed service-level agreement. That is the technical hook. Many Slack security products stop at alerts, which still leave a human to chase the user, open a ticket or clean up the exposed data elsewhere. Teleskope is trying to collapse that loop into the place where the exposure happened.
The product can tombstone content, notify the sender or require a business justification before releasing the material. Those actions happen inside Slack rather than in a separate console, and the company says the workflow creates an audit trail for security teams.
The distinction matters because Slack has become operational infrastructure, not a side channel. Customer records, contracts, product plans, credentials and internal analysis often pass through chat before they reach systems with stricter controls. Retrospective scanning is also a practical requirement, since installing a new DLP tool does not make yesterday’s leaked spreadsheet disappear.
According to Teleskope, Slack’s own native DLP is limited to Enterprise Grid, can tombstone content, and relies on manually written policies rather than machine-learning-driven classification. Teleskope also says Slack’s native DLP does not scan historical content already present in the platform. The new Teleskope for Slack Enterprise Grid integration is meant to cover both new and existing Slack data.
Ramp is cited as a customer using Teleskope across Slack and Google Workspace. The fintech company has 44 policies spanning those services, with all remediation workflows automated and roughly one hour a week of active management, according to figures provided by Teleskope.
A Ramp security leader said the switch did not require employees to change how they used Slack day to day. “The lift and shift was so seamless that users didn’t even realize we had changed platforms,” the security leader said. The same person said Teleskope “built exactly what we needed” and continued to deliver at Ramp’s pace.
Teleskope was founded in 2022 by Elizabeth “Lizzy” Nammour, a former Airbnb data security engineer, and is headquartered in New York City. Its customers include Ramp, Chevron Phillips, Notion, Polymarket, Alloy, EarnIn and Aprio. The company raised a $25 million Series A in 2026 led by M13, with Primary Venture Partners and Lerer Hippeau participating, bringing total funding to more than $32 million.
Nammour said customers wanted risk handled where employees already work rather than forcing users into another security tool. That is the right product instinct, though the useful test will be how well the classification works when Slack content is messy, informal and full of context that traditional DLP systems tend to miss.
