Govern internal and external collaboration in Slack

Netskope provides data security and compliance for Slack

Netskope for Slack

Slack is a popular enterprise collaboration service, used in organizations large and small. However, while teams can easily communicate and share files through Slack, this also creates opportunity for inadvertent sharing of sensitive data or threats such as malware to slip through.

Netskope for Slack gives you the visibility and control needed of Slack and its integrated ecosystem services so you can secure sensitive data and guard against cloud threats such as cloud malware. Gain surgical visibility into usage of Slack and its integrated ecosystem services, granular access controls, data loss prevention, and threat and malware protection. With Netskope, you have a complete risk dashboard on users, devices, and activities within Slack across public channels, messages, posts, snippets, and files. Enforce policies on messages and files that may contain sensitive information or even take action to restrict files shared through cloud storage links such as Box or Dropbox. Automated workflows such as quarantine and legal hold move potentially risky files for review into a dedicated Slack channel for security admins to review. Resolve policy violations through a single incident management dashboard in Netskope for closed-loop remediation.

Key Features

All-mode architecture

The unique Netskope all-mode architecture offers you a full array of deployment options to gain visibility and control of Slack as well as its ecosystem of connected services, whether your users are on premises or remote, using a web browser, mobile app, or sync client. Options include out-of-band API introspection into Slack as well as forward and reverse proxy modes for real-time policy controls for Slack and its ecosystem.

  • API introspection provides direct, out-of-band connection into Slack
  • Reverse proxy covers Slack access from outside your network
  • Forward proxy covers any cloud service, including Slack and its ecosystem
  • Different modes can be combined to expand your coverage
Deep context

Netskope gives you a deep understanding of your organization’s usage of Slack and of any ecosystem services that share data with Slack. You can view details such as user, device, location, service, activity, and data, and assess risk by understanding how sensitive data in Slack is being shared.

  • Understand usage by identity, service, activity, and data
  • Distinguish between different Slack instances
  • Mitigate risk of inappropriate sharing and public links
  • Focus policies on specific risky activities
Granular control

Only Netskope gives you granular visibility and control over all of your cloud services and websites. Rather than take a coarse-grained approach by blocking services and websites, set your security policies based on identity, service or website, activity, and data. Choose from actions such as block, alert, bypass, encrypt, quarantine, and coach for policy enforcement.

  • Enforce policies across all cloud services and websites based on identity, service, activity, and data
  • Protect sensitive data with Netskope DLP
  • Mix and match policy elements to carve out risk without blocking services
Comprehensive DLP

Netskope DLP protects sensitive data in the cloud with accuracy and precision, with the ability to inspect all sanctioned and unsanctioned cloud services as well as traffic to websites. Sensitive content is detected across 1000+ file types and across structured and unstructured data, using 3,000+ data identifiers, metadata extraction, proximity analysis, fingerprinting, exact match, and more.

  • Control sensitive data in Slack and en route to and from all cloud services
  • Get the highest degree of accuracy with fingerprinting and exact match
  • Further increase accuracy with keyword dictionaries, global data identifiers, and more
  • Target DLP policies using context like user, group, device, service, and activity
Threat protection

Netskope is the only CASB with complete threat defense for Slack and its service ecosystem, combining unparalleled cloud visibility with multi-layered threat detection and integrated remediation workflows. Netskope can quickly detect, prevent, and remediate the effects of cloud threats, which too often evade existing security solutions.

  • Threat protection with unique cloud vantage point
  • Detect anomalies that could indicate an active threat
  • Proprietary threat intelligence from Netskope Threat Research Labs complemented by 40+ external sources

Top Use Cases

Control access

Detect all access to Slack, regardless of where your users are located or what device they are using. Apply the appropriate access control policy based on the situation. For example, allow users on unmanaged devices to view content in Slack but restrict other activities such as downloads and shares to protect sensitive data.

Stop threats

Slack makes it easy to share, but this same capability makes cloud services like Slack an attractive target for malicious actors. Protect your organization from cloud threats such as malware and ransomware and also detect unusual data movement or user activity that could indicate the presence of an active threat in your environment.

Prevent data loss

Netskope provides a unique vantage point across all of your cloud services to help you detect data movement that could signal a data exfiltration attempt by an insider. Netskope anomaly detection combined with our DLP capabilities can correlate the download of sensitive data from Slack with the upload of the same data to a personal cloud service.

Coach users

Make your users part of your Slack security solution. Netskope can provide your users with automated, customized coaching messages to address undesirable cloud activities. For example, you can coach them to use Slack when they try to use a personal cloud collaboration tool, or warn them about sensitive data handling policies when they try to upload sensitive data to a risky cloud service.
