Proofpoint on Demand

Proofpoint on Demand is a cloud-based cybersecurity platform that offers a wide range of services to protect businesses against cyber threats. This includes email security, threat intelligence, information protection, and compliance solutions. The Proofpoint on Demand app for Sumo Logic provides insight into the functioning and effectiveness of your email security policies, allowing you to make informed decisions to improve security posture. This app will further provide information about the encryption status of the communication.

Key features of the Proofpoint on Demand app include:

• Email security monitoring. Monitor message traffic to detect and prevent spam, phishing, and other email-borne threats.
• Compliance monitoring. Monitor email communications for compliance with internal policies and external regulations such as Data Loss Prevention (DLP), Domain-based Message Authentication, Reporting and Conformance (DMARC), and other relevant regulations.
• Incident investigation. Quickly investigate potential security incidents by searching and analyzing email security and compliance data. This includes identifying the source of a security threat and the extent of its impact.
• User behavior monitoring. Monitor behavior related to email communication to identify potential insider threats or unauthorized access.

Log types

This app uses Proofpoint on Demand source to collect the data from Proofpoint on Demand (PoD) Log Service and uses the secure WebSocket (WSS) protocol, which securely stores the required authentication, scheduling, and state tracking information.

Set up collection

To set up Cloud-to-Cloud Integration Proofpoint on Demand Source for the Proofpoint on Demand app, follow the instructions provided. These instructions will guide you through the process of creating a source using the Proofpoint on Demand Source category, which you will need to use when installing the app. By following these steps, you can ensure that your Proofpoint on Demand app is properly integrated and configured to collect and analyze your Proofpoint on Demand data.

Installing the Proofpoint on Demand app​

To install the app, do the following:

1. From the Sumo Logic navigation, select App Catalog.
2. In the Search Apps field, search for and then select your app.
   Optionally, you can scroll down to preview the dashboards included with the app.
3. To install the app, click Install App.
4. Click Next in the Setup Data section.
5. In the Configure section of the respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category, and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Your app will be installed in the Installed Apps folder and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, updating with full graphs and charts over time.

Viewing Proofpoint on Demand dashboards​​

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filter with template variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.

Message Monitoring

The Proofpoint on Demand - Message Monitoring dashboard offers valuable insights into message traffic, such as the number of distinct sender and receiver domains, geo-locations of senders, and blocked messages. It also tracks trends in the actions taken on messages and provides a list of the top 10 senders and receivers. Leveraging this information gives you a better understanding of the email traffic patterns and takes action to improvise email security posture.

Security Overview

The Proofpoint on Demand - Security Overview dashboard is designed to monitor email communications for compliance with both internal policies and external regulations, such as DLP and DMARC. It includes widgets for geo-location tracking of messages from high-risk countries, a summary of policy results for DMARC, DLP, Anti-Spam and Anti-Virus, and messages in the quarantine folder by category. In addition, the dashboard includes a TLS message trend chart that displays the ratio of encrypted to unencrypted messages, along with insights into the unencrypted sender and receiver domains. Overall, the Security Overview dashboard helps organizations maintain compliance with relevant regulations and policies while also providing valuable insights to improve their email security posture.
