Quorum Cyber - Data Loss Prevention Managed Service using Microsoft Purview

Quorum Cyber

Quorum Cyber's Data Loss Prevention Managed Service leveraging the power of Microsoft Purview

Our Data Loss Prevention (DLP) service provides the design and deployment of DLP policies. This stage defines the tuning, severity, and priority for the business with regards to the exfiltration and oversharing of sensitive information.

Once this is in place, Quorum Cyber will onboard your tenant into the Security Operations Centre (SOC) for the set-up of DLP signals into Sentinel and provide oversight into Quorum Cyber’s Clarity solution.

The aim of this service is to provide a comprehensive solution that will help prevent data loss and protect the customer’s data to meet regulatory and compliance requirements such as GDPR and financial data regulations across Microsoft 365 Exchange/SharePoint services and endpoints such as Windows 10/11/macOS.

Design/Deploy:

Our team will work with your business to define DLP policies such as GDPR/financial regulations. However, the initial packaged offering will include: • GDPR information—Personally Identifiable Information (PII) • Financial information—data related to credit card or bank numbers • Custom—identified by the customer. Examples include data types, classification, and boundaries.

These policies will help identify and prevent sensitive data from leaving the organisation. Our team will take into consideration the different types of data, such as PII and financial data, and work with the business to define the severity and priority of each policy.

Tuning:

Quorum Cyber will tune the DLP policies to ensure that the number of alerts generated within a period of time is manageable. Our target is to keep the number of alerts to a maximum of 20 per month. This will help the business focus on the critical alerts that require immediate attention. Alerts over this cadence will be at additional cost in reference to the current managed service taken with Quorum Cyber. The signals for DLP can derive from the Microsoft 365 services, such as Email (Exchange Online) and sharing out of the platform (SharePoint Online, OneDrive for business). If the customers are set up with Quorum Cyber’s Managed Extended Detection & Response (XDR) service, these signals can also come from the endpoint for common exfiltration activities.

Severity:

Our team will assist the customer in defining the severity of each DLP alert, although it will be the priority that is set by each individual customer. This enrichment of the alerts will help the SOC team triage the alerts, so they are dealt with accordingly and the correct prioritisation given to the response. Critical alerts are dealt with promptly in accordance with the SOC team’s SLAs, while less critical alerts can be addressed later through weekly digests.

Ingesting DLP alerts into Sentinel:

Our team will ensure that DLP alerts are ingested into Microsoft Sentinel (Microsoft’s cloud-native Security Information and Event Management (SIEM) solution). These details are fed into Quorum Cyber’s Clarity solution as a single pane of glass for our customers to consume incidents through dashboards, reports, and triaged alerts.

Conclusion:

Our managed DLP service provides a comprehensive solution that will help prevent the loss and exfiltration of sensitive data. Quorum Cyber will work with the business to define DLP policies that are aligned to their business, while ensuring the policies work through testing and tuning, and help define the severity and priority of each policy. As a minimum, we will also provide a weekly digest so our customers can clearly see what’s happening with their data across their Microsoft solutions and be able to provide an advanced, full-service offering that enhances DLP alerts through a managed SOC process, direct feedback to the business, and DLP incident response services. Our service relies on the automation and logic within the platform that’s customised to each customer’s business needs.
