Enforce data loss prevention policies across Slack

Skyhigh enforces DLP policies for files and messages across Slack channels to ensure compliance with regulations and internal policies. Skyhigh supports DLP rules based on keywords, data identifiers, user groups, and regular expressions. Enforcement actions include coach users, notify administrator, block, encrypt, quarantine, and tombstone. Leverage pre-built industry templates, create custom policies in Skyhigh, or leverage policies in an existing on-premises DLP solution.

Unified DLP reporting and remediation

Skyhigh reports on DLP violations in Slack and other cloud services in a unified interface with highlighted excerpts revealing the exact content that triggered the DLP policy. During review, if a file does not violate a policy, the reviewer can rollback the remediation action to restore the file and/or its sharing permissions. Quarantined files are stored in a secure account within Slack, not in Skyhigh’s platform, for added security.

Deep integration with on-premises DLP solutions

With Skyhigh you have the option of leveraging our best-in-class DLP engine or the policies in your existing on-premises solution such as Symantec DLP, Intel McAfee DLP, Forcepoint DLP, and more. Skyhigh optionally performs a first-pass content inspection, brokers inspection by the on-premises solution, acts as an enforcement point to apply policies to data in the cloud, and registers enforcement in the on-premises solution that maintains the policy.

Detect internal and external threats

Skyhigh captures a complete record of all user activity in Slack and leverages machine learning to analyze activity across multiple heuristics and accurately detect threats. As a comprehensive cloud security platform, Skyhigh can detect cross-cloud threats that involve usage across Slack and other cloud services. As threats are resolved, Skyhigh automatically incorporates this data into its behavioral models to improve detection accuracy.

Insider threats

Skyhigh automatically constructs a behavior model with dynamic and continuously updated thresholds for each user and team to identify activity indicative of insider threat, whether the threat is accidental or malicious. Using Guided Learning, you can fine tune the detection of cloud-based threats by providing feedback to the system that is incorporated into models of user behavior to more accurately detect future threats.

Compromised accounts

Skyhigh detects compromised account activity in Slack based on brute force login attempts, logins from new and untrusted locations for a specific user, and consecutive login attempts from two locations in a time period that implies impossible travel, even if the two logins occur across two cloud services. Darknet Intelligence reveals user accounts for sale online that are at risk of compromise.


Secure BYOD access to Slack

Skyhigh enforces fine-grained access policies, such as allowing document preview on unmanaged devices but preventing downloads to devices without appropriate endpoint security. Skyhigh can also integrate with identity management solutions to require additional factors of authentication for users based on device or access patterns.

“Skyhigh allows us to extend DLP outside the perimeter and into the cloud, and the user experience is seamless.”

Mike Benson, Chief Information Officer

“Our users never see Skyhigh even though it is a key part of our IT security strategy, allowing us to keep our users and data safe so they can have global access from any device.””

Jeff Haskill, Chief Information Security Officer

“Skyhigh helps us understand how employees use Salesforce to identify insider threats, compromised credentials, and excessive privileged user access.”

Mike Bartholomy, Senior Manager, Information Security

Make Slack your corporate standard

Skyhigh identifies collaboration solutions that employees use in place of the corporate standard, Slack, and provides a risk rating for each service. Using Skyhigh, you can enforce risk-based governance controls and coach users to Slack to improve collaboration while also reducing cost and risk.

Compliance

Cloud Data Loss Prevention

Enforces DLP policies based on data identifiers, keywords, and structured/unstructured fingerprints across data at rest and uploaded or shared in real time.

Secure Collaboration

Enforces external sharing policies based on shared links and content and educates users on acceptable collaboration policies.

Pre-Built DLP Templates

Provides out-of-the-box DLP templates and a broad range of international data identifiers to help identify sensitive content such as PII, PHI, or IP.

Structured Data Fingerprinting

Fingerprints billions of unique values stored in enterprise databases and systems of record and supports exact match detection of each value.

Unstructured Data Fingerprinting

Fingerprints sensitive files and detects exact match and partial or derivative matches with a policy-defined threshold for percentage similarity to the original.

Multi-Tier Remediation

Provides coach user, notify administrator, block, apply rights management, quarantine, tombstone, and delete options and enables tiered response based on severity.

Policy Violation Management

Offers a unified interface to review DLP violations, take manual action, and rollback an automatic remediation action to restore a file.

Match Highlighting

Displays an excerpt with content that triggered a DLP violation. Enterprises, not Skyhigh, store excerpts, meeting stringent privacy requirements.

Closed-Loop Policy Enforcement

Optionally leverages policies in on-premises DLP systems, enforces policies, and registers enforcement actions in the DLP system where the policy is managed.

Governance

Shadow IT Discovery

Discovers all shadow IT cloud services employees are using in place of the corporate standard, Slack.

Coaching and Enforcement

Displays just-in-time coaching messages guiding users from unapproved services to Slack and enforces granular policies such as read-only access.

User Behavior Analytics

Automatically builds a self-learning model based on multiple heuristics and identifies patterns of activity indicative of a malicious or negligent insider threat.

Account Compromise Analytics

Analyzes login attempts to identify impossible cross-region access, brute-force attacks, and untrusted locations indicative of compromised accounts.

Privileged User Analytics

Identifies excessive user permissions, inactive accounts, inappropriate access, and unwarranted escalation of privileges and user provisioning.

Malware Protection

Identifies and blocks known signatures, sandboxes suspicious files, and detects behavior indicative of malware exfiltrating data via cloud services and ransomware.
