Proofpoint's Email Isolation solution is a powerful tool for protecting against email-based threats, such as phishing and malware attacks. By isolating potentially dangerous email messages in a secure environment, Proofpoint prevents these messages from reaching end-users and reduces the risk of an attack succeeding.
With Email Isolation, administrators can configure isolation policies based on specific criteria, such as sender reputation, attachment type, or keyword filtering. Isolated messages are stored securely and can be analyzed for threats, providing visibility into potential attacks and allowing organizations to take action to prevent them.

Vendor setup
Minimum configuration required for basic pulling
Although this collector supports advanced configuration, the fields required to retrieve data with basic configuration are defined below.
This minimum configuration refers exclusively to those specific parameters of this integration. There are more required parameters related to the generic behavior of the collector. Check setting sections for details.

Steps
Obtain API key
Navigate to Product Settings → Reporting API.
The API key can be generated and found in the Isolation Reporting API Console's main viewing panel under Reporting API Key.
Assigning necessary permissions
Only the credentials above are required.
Run the collector
Once the data source is configured, you can either send us the required information if you want us to host and manage the collector for you (Cloud collector), or deploy and host the collector in your own machine using a Docker image (On-premise collector).
Collector services detail
This section is intended to explain how to proceed with specific actions for services.
Browser and email isolation
Internal process and deduplication method
Proofpoint Isolation API stores events up to 30 days in the past. All isolation events are fetched on a polling basis. If there are more events available for a given time period than can be retrieved in a single page (limited to 10,000 records per page), the collector continues to fetch new events until none are available for the query window.
Events are sorted by the date field and deduplicated by comparing the hash signature of the event against previous pulls.
Devo categorization and destination
All events of this service are ingested into the table tap.proofpoint.isolation.url_isolation

A successful run has the following output messages for the setup module:

Restart the persistence
To restart the service, the user must reconfigure the start_time_in_utc parameter within the configuration file. When the collector is restarted, the system will register the new start time and begin pulling events from that date.

Initialization
The initialization module is in charge of setup and running the input (pulling logic) and output (delivering logic) services and validating the given configuration.
A successful run has the following output messages for the initializer module:

Events delivery and Devo ingestion
The event delivery module is in charge of receiving the events from the internal queues where all events are injected by the pullers and delivering them using the selected compatible delivery method.
A successful run has the following output messages for the initializer module:
The Integrations Factory Collector SDK has 3 different senders services depending on the event type to delivery (internal, standard, and lookup). This collector uses the following Sender Services:
Sender services
Description
internal_senders
In charge of delivering internal metrics to Devo such as logging traces or metrics.
standard_senders
In charge of delivering pulled events to Devo.
Sender statistics
Each service displays its own performance statistics that allow checking how many events have been delivered to Devo by type:
Logging trace
Description
Number of available senders: 1
Displays the number of concurrent senders available for the given Sender Service.
sender manager internal queue size: 0
Displays the items available in the internal sender queue.
Standard - Total number of messages sent: 57, messages sent since "2023-01-10 16:09:16.116750+00:00": 0 (elapsed 0.000 seconds
Displays the number of events from the last time and following the given example, the following conclusions can be obtained:
44 events were sent to Devo since the collector started.
The last checkpoint timestamp was 2023-01-10 16:09:16.116750+00:00.
21 events where sent to Devo between the last UTC checkpoint and now.
Those 21 events required 0.007 seconds to be delivered.
Check memory usage
To check the memory usage of this collector, look for the following log records in the collector which are displayed every 5 minutes by default, always after running the memory-free process.
The used memory is displayed by running processes and the sum of both values will give the total used memory for the collector.
The global pressure of the available memory is displayed in the global value.
All metrics (Global, RSS, VMS) include the value before freeing and after previous -> after freeing memory
