Protect against internal and external threats to data in Office 365

Skyhigh captures a complete record of all user activity in Office 365 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. In response, Skyhigh takes immediate action to suspend access or force multi-factor authentication to reinforce Office 365 security.

  • 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. In response, Skyhigh can alert security admins and terminate access. Privileged User Analytics identifies risk from dormant administrator accounts, excessive permissions, and unnecessary escalation of privileges and user provisioning.

  • Compromised accounts

    Skyhigh detects compromised account activity in Office 365 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. In real time, Skyhigh responds to threats and protects data by requiring additional authentication factors. Darknet Intelligence reveals user accounts for sale online that are at risk of compromise.

Office 365 data loss prevention

Office 365 data loss prevention

Skyhigh enforces DLP policies for data at rest and in motion to ensure compliance with regulations and internal policies. Skyhigh supports rules based on keywords, data identifiers, and regular expressions. Enforcement actions include alerting, tombstoning, blocking, and quarantining. 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 all Office 365 applications and other cloud services in a unified interface. 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 Office 365, not in Skyhigh’s platform, for added security.

  • Flexible DLP platform

    Skyhigh can integrate with leading on-premises DLP solutions from Symantec, EMC RSA, Intel McAfee, and Websense to enforce existing DLP policies. Skyhigh brokers content inspection by on-premises solutions, acts as an enforcement point to apply actions to files in the cloud, and registers enforcement actions in the on-premises DLP solution that maintains the policy.

Analyze sharing and enforce collaboration policies

Skyhigh audits collaboration activity and visually summarizes all sharing events within the organization, with partners, with personal emails, and via untraceable shared links. Secure Collaboration enforces collaboration policies based on sharing activity and document content, and can take action by modifying permissions and links.

Analyze sharing and enforce collaboration policies

“Using Skyhigh along with Microsoft Graph, companies can leverage the massive productivity gains enabled by Office 365 while meeting their various compliance, threat protection and data security requirements.”

Rob Lefferts, General Manager, Extensibility at Microsoft

“Skyhigh helps us securely enable high-impact cloud services like Office 365 while ensuring data security and compliance with HIPAA and HITECH.”

Mark Dunkerley, Manager of Messaging, Mobile and Video Services

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

Mike Benson, Chief Information Officer

“When IT can bring the audit committee and executive members together and they are comfortable using the cloud, it is huge. Skyhigh is mitigating and lowering risk. It's a fact.”

Jeff Haskill, Chief Information Security Officer

Key Features

Threat Protection

Office 365 SOC

Delivers a threat protection dashboard and incident-response work flow for potential insider threats, privileged user threats, and compromised accounts.

Threat Modelling

Correlates multiple anomalous events within Office 365 or across Office 365 and other cloud services to accurately separate true threats from simple anomalies.

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 Access 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, zombie administrator accounts, inappropriate access to data, and unwarranted escalation of privileges and user provisioning.

Configurable Sensitivity

Provides an adjustable sensitivity scale for each anomaly type with real-time preview showing the impact of a change on anomalies detected by the system.

Cloud Activity Monitoring

Provides a comprehensive audit trail of all user and administrator activities to support post-incident investigations and forensics.

Darknet Intelligence

Identifies stolen credentials acquired in phishing attacks and leaked from breached cloud services to reveal users and services at risk.


Shadow IT Discovery

Identifies any shadow IT cloud services employees are using in place of the corporate standard, OneDrive, Yammer, and SharePoint.

Coaching and Enforcement

Displays just-in-time coaching messages guiding users from unapproved services to Office 365 and enforces granular policies such as read-only access.

On-Demand Data Scan

Identifies sensitive data stored at rest in Office 365 with the ability to schedule periodic scans based on date range, user, sharing status, and file size.

Usage Analytics

Identifies all users and groups accessing Office 365 and reveals which users are accessing sensitive data.

Collaboration Analytics

Visually summarizes sharing with third-party business partners, personal emails, and internal users and reports on policy exceptions.


Cloud Data Loss Prevention

Enforces DLP policies based on data identifiers, keywords, and regular expressions across data stored at rest and data uploaded or shared in real time.
