Billing in LimaCharlie is done on monthly cycles and per-Organization (multi-tenant).

Some features like centralized billing are available to larger LC users like MSSPs, if you would like more details contact us at

For exact pricing see the LimaCharlie website or Web App.


Endpoints (EDR)

The EDR service is the foundation of LimaCharlie. In order to make billing simpler and more predictible, it is based on a Quota set by the user.

The Quota is the number of sensors (agents) concurrently online that should be supported by the given Organization. The Quota applies to concurrently onlie sensors meaning that you may have more sensors registered than your quota.

If sensors attempt to connect to the cloud while the Quota is full, they will simply be turned away for a short period of time. In that case, a special sensor_over_quota will also be emitted which you can use in D&R rules for automation.

The endpoint service includes Outputs as well as D&R rules processed in real-time.

Sidecar Sensors

A special case around Quota use is called Sidecar Sensors. At the moment the only Sidecar Sensor is the Chrome sensor. A Sidecar Sensor will not count against your Quota as long as it has a correspondant "normal" sensor.

For example, let's say you have 10 Windows sensors and 10 MacOS sensors online for a total of 20 "normal" sensors. This means you will be able to have up to 20 other Chrome sensors online without using any extra quota. If 25 Chrome sensors become online however, 5 extra Quota will be consumed.

The intent is to allow Chrome sensors to be companion sensors enhancing visibility of your existing LimaCharlie deployment without making Chrome-only deployments effectively free.

Insight (Retention)

Insight is also a foundational service of LimaCharlie. It provides a flat 1 year of full retention (full telemetry) for a single price in order to make billing more predictible.

Replay (Retroactive Scanning)

Replay allows you to run D&R rules against external or historical telemetry. Not to be confused with Searching for specific IoCs which is a free feature of Insight.

Its pricing is based on two factors:

  1. The Complexity of the D&R rule.
  2. The number of events (telemetry) to be replayed.

The metric used for billing is a combination these two factors: "number of operation evaluations".

A rule with a single operator like this:

op: ends with
path: event/FILE_PATH
value: evil.exe

replayed against 100 events would result into 100 "operation evaluations".

Final billing is based on blocks of those "operation evaluations".

The best way to evaluate the cost of a specific rule through Replay is to launch a limited Replay job of a given rule first. The results of the job will contain the number of operation evaluations performed. You can then extrapolate an estimate of the cost.

Replay jobs can also be launched with a maximum number of operation evaluations to consume during the life-cycle of the job. This limit is aproximate due to the de-centralized nature of Replay jobs and may vary a bit.

Artifact Collection

The Artifact Collection service allows you to ingest artifacts like Syslogs, Windows Events Logs as well as more complex file formats like Packet Captures (PCAP), Windows Prefetch files, Portable Executable (PE) etc.

Ingested files can then be downloaded as originals or viewed in parsed formats right from your browser. You can also run D&R rules against them.

Unlike Insight, the retention period is variable based on a number of days (up to 365) as specified by the user at ingestion time.

All billing for it is done at ingestion time based on the number of days and the size of the file. The billing metric is therefore "byte-days".

For example, a file that is 100 MB and is ingested with a retention period of 10 days would be one-time billed for 100 X 10 MB-days.
