On November 29th, MITRE ATT&CK released the results of their first round of endpoint security evaluations. The evaluations simulated malicious activity from the APT-3 campaign against seven products. While our analysis directly compares the performance of vendors, we want to give ample credit to every vendor with the willingness to participate in this assessment. It appears one vendor may have dropped out during the process, reasons unknown.

The full results for each product can be viewed here: The results are displayed on the MITRE ATT&CK killchain table or as a scrollable table broken down by step. However, we didn’t identify an easy way to compare results and contextualize one vendor with respect to other vendors, which is crucial for understanding the relative strengths and weaknesses of the vendors. We were particularly interested in this type of cross-sectional data and the potential benefits it might bring. To perform this cross-sectional analysis, we took the MITRE-provided JSON results, extracted the detection information, and created a simple proof-of-concept database. The database is publicly available on our GitHub along with an example HTML report of detections by technique ID ( If you wish to perform your own queries easily, you can use an in-browser SQLite viewer like with the database. In this post we will cover a small subset of the insights this approach to analyzing the MITRE data can produce.



Analysis One:  Techniques with the largest detection gaps


The first thing we wanted to understand was where the biggest defensive gaps existed for defensive tooling. To do so, we searched for any technique where a given vendor had no hits in any of the five main detection capabilities then tallied the results. The raw query for this was:

select  count(Vendor) as Product_Misses, techniquename, techniqueid from edr where Telemetry = 'no' AND Indicator = 'no' AND Enrichment = 'no' AND General = 'no' AND Specific = 'no' group by techniqueid ORDER BY Product_Misses DESC

From our query, we can see that only 4 (out of 56) techniques were missed by all vendors. It is important to note that 2 of the 4 (“PowerShell” and “Execution through API”) were not directly tested, so no detection capabilities would be expected.

However, we can adjust the above query to exclude weaker detection capability categories such as telemetry. When we filter the results to include just specific and general behaviors, the number of techniques detected by zero vendors dramatically increases.

select count(Vendor) as Product_Misses, techniquename, techniqueid from edr where General = 'no' AND Specific = 'no' group by techniqueid ORDER BY Product_Misses DESC

Whether this is a more accurate depiction of detection is still dependent on the organization. Some organizations pay little-to-no attention to the types of telemetry counted as detection, meaning this query is more accurate. In other cases, more vigilant organizations might pick up that telemetry, meaning the original query was the more accurate one. Additionally, telemetry becomes extremely important during threat hunting activities where a defender needs to track the activities of a malicious actor.



Analysis Two: Detections by Vendor


Another element we wanted to understand was the performance of each vendor. Looking at overall performance (actual detections vs total detection opportunities) of each vendor can help when determining the overall maturity of a vendor. A query for this is:

select vendor, count(vendor) as total_detections from edr WHERE Telemetry = 'yes' OR Indicator = 'yes' OR Enrichment = 'yes' OR General = 'yes' or Specific = 'yes' group by vendor;

We can see that Crowdstrike had the most detections overall with SentintelOne trailing closely behind. However, we can apply the same filtering process as insight one and get a much different picture.

select vendor, count(vendor) as total_detections from edr WHERE General = 'yes' or Specific = 'yes' group by vendor;

Crowdstrike again remains on top, with a relatively small difference in totals compared to other vendors. However, SentinelOne dropped to last place from second. In this case, the filter of just generic and specific behaviors is meant to help provide insight into which vendor potentially had more robust detections against a wide breadth of techniques.



Analysis Three: Per-technique breakdown


While the previous two queries provide more general insight into the cross-sectional data, what if we need to drill down on a specific technique? For example, if we want to understand how all vendors performed against technique T1110 (Brute Force), we can use a query like

select * from edr where techniqueid == 'T1110'

From this, we get a consolidated view of all performance for all vendors. We can also see any modifiers applied to the detection capabilities in the three rightmost columns (see It should be noted that this type of view does lose resolution in comparison to the full evaluation table since it does not break down detection capabilities by step.

If we want to view multiple techniques where there was a detection of a generic or specific behavior for any vendor, we can modify the above query.

select vendor,techniquename,techniqueid,general,specific,tainted,delayed,configuration from edr where techniqueid in ('T1110','T1048') and 'yes' in (general, specific) order by techniqueid

Here we are looking at two techniques (T1048 and T1110) across all vendors for general or specific behavior detections. The rightmost three columns are included since they indicate whether or not the detection has a modifier



Putting to Good Use


While the above information is useful, it should not be considered a direct ranking of product quality. Products should be evaluated in each environment, as part of a defense-in-depth strategy. Consider using these results as a starting point for considering EDR tools, not the decision-maker. To better understand the testing process, MITRE provides a good starting point here: Ultimately, organizations should be sensitive to the differences in detections across vendors and perform thorough research before choosing the best one for their environment.
