How Strac Slack DLP Works?

Continuous & Historical Scanning

Strac detects, classifies, and redacts sensitive data elements using 100s of built-in machine learning detectors and custom configurations set by customers.

Redaction aka Masking

Strac masks (aka redacts) sensitive data in messages and files. However, if needed, authorized personnel can still view these redacted contents via Strac’s UI Vault, ensuring confidentiality without blocking critical access.

DLP Remediation

Alerting: Notifies admins when sensitive data (e.g., PII, PHI) is detected in Slack messages or files.
‍Redaction: Automatically removes sensitive data from Slack messages in real-time.
‍Deletion: Permanently deletes sensitive messages or file attachments to prevent unauthorized access.

Public, Private Channels & DMs

Strac’s capabilities span across all Slack communication channels, ensuring consistent protection whether the interactions are on public channels, private channels, direct messages (DMs), or group DMs.

Slack Pro, Business+, Enterprise Plans

Independent of the Slack subscription tier, Strac delivers its robust security measures consistently, ensuring every user benefits from its protective shield - ranging from Pro, Business Plus to Enterprise Plans

Slack DSPM (Data Discovery)

Slack DSPM gives visibility into sensitive data already stored in Slack—across messages, files, channels, DMs, and Slack Connect. It identifies what data exists, who has access, and where exposure risks are. Perfect complement to DLP’s real-time controls.

What our customers say

Hear from companies who leveraged Strac to secure and accelerate their business

“Strac protects our customer support communication channels”

To protect our clients as well as ourselves, we needed a secure way to protect our communication channels for security and compliance reasons. We used Strac's Email Redaction solution where Strac protects all our employee inboxes. The redaction experience is beautiful, easy, and secure. It catches all kinds of sensitive pdfs, jpegs, images, word docs, and even in email bodies. The integration was up and running in a few minutes. The service offered by Strac's team is the best I have seen as we work with a lot of SaaS providers.

We Highly Recommend Strac to all businesses who want to protect their SaaS apps.

Head of IT at Trivium

“Strac secures our PII on customer support and on backend servers”

On our Intercom customer support, anyone can send sensitive data to a business and a business is liable even if they did not ask for it. Strac solves that huge problem by automatically redacting sensitive data that is shared over Intercom with their accurate machine learning technology. We also leveraged Strac's Zero Data architecture via tokenization & proxy APIs so that we don't have to worry about touching sensitive data and documents on our backend servers. Strac dramatically reduces security and SOC compliance risks for us while significantly improving security posture for Seis. Strac's solutions were extremely easy to integrate (literally in few minutes) and scaled to meet our needs.

“Loved Strac's Interceptor Solution”

We leverage Strac's tokenization & interceptor solution so that we don't have to worry touching sensitive SSNs and can leverage Strac's security expertise in building hundreds of security controls.

We could also detect identity fraud using Strac's unique tokenization solution which we are really happy with. That saved us a ton of financial losses and headaches. We are looking forward to integrating with various other Strac solutions deep into our tech stack.

Slack DLP Use Cases

Scenario

A healthcare provider uses Slack channels to communicate patient updates and treatment plans. However, staff might accidentally share PHI—like medical record numbers, diagnoses, or lab results—in a public channel instead of a private one.

How Strac's Slack DLP Helps

Strac’s Slack DLP solution automatically scans messages and attached files for protected health information. When it detects PHI, Strac instantly redacts, redacts on a delay or quarantines the sensitive data, ensuring patient privacy and HIPAA compliance. Real-time alerts and incident tracking tools also enable administrators to swiftly respond to any compliance risks.

Scenario

An employee or sometimes customer shares a PDF of a customer's ID document (DL/Passport) or credit card number in a slack channel for quick review. Unbeknownst to them, the file is accessible by a broader audience in Slack, creating a potential PCI-DSS compliance risk.

How Strac's Slack DLP Helps

With Strac’s Slack DLP, financial institutions can enforce policies to detect and mask/redact credit card numbers and other financial identifiers. When sensitive data is found, Strac either redacts it on the fly or prevents the file from being shared entirely. Detailed reporting features also allow compliance teams to demonstrate PCI-DSS adherence and streamline audits.

Scenario

A tech startup frequently shares proprietary code snippets, product roadmaps, and strategic documents in Slack. An employee might accidentally post these materials in a channel that contractors or external partners have access to.

How Strac's Slack DLP Helps

Strac’s Slack DLP solution scans all shared content—text, images, and attachments—for keywords and patterns associated with IP or confidential data. It can quarantine files or redact text in real-time, limiting exposure to only authorized channels. If sensitive material does slip through, Strac’s audit trail allows security teams to quickly trace and mitigate the incident.
