• It performs frequent security assessments on production hosts and addresses vulnerabilities that could potentially compromise the environment. It also conducts security checks on the Slack infrastructure to identify threats that violate the terms of service.

Does Slack have a built-in DLP?

No Slack relies on third-party apps for DLP functionality, so a dedicated solution is crucial for HIPAA compliance. If your organization needs to comply with HIPAA regulations, it's essential to have a DLP solution in place when using Slack. 

Slack Connect and DLP

With Slack Connect's Data Loss Prevention (DLP) feature, securing cross-company collaboration just got easier. You can now, 

• minimize the risk of sharing sensitive and confidential information with external organizations,
• monitor all channels and direct messages sent and received by your organization's users, ensuring that nothing breaches your established policies, and
• control your data and collaborate with external partners confidently and seamlessly

But that’s not all, here are a few benefits of Slack Connect and DLP⬇️

1. Admin privileges

The organization's primary owners and members with admin system roles can assign DLP admin system roles to other members. DLP admins can enhance security by creating custom rules using regular expression (regex) format to effectively flag messages or files for administrative action.

They have the flexibility to choose whether to hide tombstone messages or files until they can be reviewed. This feature leads to an efficient review process, ensuring that potential violations are not overlooked. DLP admins play a crucial role in maintaining compliance by reviewing rule violations and taking appropriate action on flagged messages and files.

2. Security alerts

Managing alerts for policy violations in your organization has never been easier. With the Slack DLP dashboard, you'll receive instant alerts whenever a member sends a message that violates a DLP rule. From the dashboard, you can efficiently handle these alerts by archiving them, deleting the corresponding message, or restoring it if it was initially hidden. 

3. Seamless data management

Ensure seamless data management within your organization with advanced retention settings in Slack. Rest assured that messages and files sent by your members will be subject to your organization's retention policies. 

Any content received from individuals outside of your company will be handled based on their respective organization's retention settings. In addition, Slack’s message editing and deletion settings are tailored specifically for your organization. Only members of your team can edit or delete messages sent by them, ensuring complete control over communication within your workspace.

4. Powerful encryption

Starting September 2020, Enterprise Key Management (EKM) is now available for Slack Connect. This update ensures that messages and files sent by members of your organization are encrypted using your own keys. And here's the best part - if you're already an EKM customer, this encryption will also be applied retroactively to previous communications. If other companies are also EKM customers, any messages or files they send you will be encrypted with their keys. With EKM, you can ensure the utmost security and protection for all your communications on Slack Connect.

5. Content regulation

Organizations can now leverage e-discovery and data loss prevention (DLP) solutions to effectively review and regulate content across channels and DMs shared with individuals from other companies. 

The Discovery API allows all organizations to access and read content in channels and DMs shared with external parties. However, only messages and files sent by members of your own organization within a channel or DM can be edited or deleted using the Discovery API. While using user methods, the Discovery API will return the display names of members from external organizations. 

However, this information will not be displayed alongside the conversation history. Regardless of an organization's email display settings, email addresses of members from external organizations will be returned via Discovery API.

Essential functionalities for a DLP

When considering data loss prevention (DLP) functionalities for Slack, it is crucial to look for these essential features. 

1. Content analysis

The DLP solution should be able to scan messages, files, and other content shared within channels and direct messages. It should be able to analyze the content for sensitive information like personally identifiable information (PII), financial data, intellectual property, or any other confidential information. By ensuring a robust content scanning feature in your DLP solution for Slack, you can proactively identify and prevent potential data breaches or leaks. This ultimately helps safeguard your organization's reputation and ensures compliance with regulatory requirements.

2. Flexibility

Organizations should be free to establish and tailor DLP rules to meet their unique requirements for data security. Administrators should be able to establish guidelines and scenarios that result in policy breaches using specific patterns or keywords. It should also monitor policy violations and take appropriate actions.

3. Real-time alerts

The DLP solution should provide real-time alerts and notifications to notify administrators promptly of policy violations. This lets them immediately address the violation, minimizing data loss or exposure risks. Additionally, the automated actions offered by the DLP solution ensure consistent policy enforcement. Based on the severity of policy violations, these automated actions may include warning the user, blocking the message from being sent, or quarantining the content for review.

4. Actionable insights

DLP solutions should provide visibility into policy breaches, data leakage events, and trends to enable robust reporting and auditing capabilities. These insights help companies assess their situation and make well-informed decisions to improve it.

5. Slack DLP Integration with other tools

It should integrate seamlessly with other tools to improve enterprise data security options. It should ensure total security using data loss prevention solutions, security information and event management (SIEM) systems, or other applicable safety measures.

6. Customization

It should provide the option to add custom detectors, rules, keywords, regexes, and pre-built detectors that cover a wide range of data types. It should be able to scan files and messages from various file categories, including xls/xlsx, doc/docx, CSV, plain text, ppt/pptx, PDF, HTML, and others.
