EPR Endpoint Prevention and Response Report Released by AV-Comparatives

AV-Comparatives’ EPR CyberRisk Quadrant shows the Strategic Leaders, CyberRisk Visionaries and Strong Challengers for endpoint prevention and response.

The growth of targeted attacks presents a serious risk to enterprises and public bodies. Organisations are increasingly being targeted by cyber-criminals for reasons of industrial espionage, sabotage or profit. Recent attacks on health services in Ireland and the United States government agencies are just a few examples of many. The complexity of targeted attacks requires very sophisticated prevention and response solutions.

Endpoint prevention and response (EPR) products aim to prevent such attacks, and allow detailed investigation, analysis and response of attempted break-ins. AV-Comparatives has published the report of its Endpoint Prevention and Response Test, which assessed how effective leading EPR products are at stopping and analysing targeted attacks. The top Strategic Leader Award was given to Bitdefender, Palo Alto Networks, Check Point, CrowdStrike, F-Secure, Cisco and ESET. Broadcom was awarded with the CyberRisk Visionaries award. Two further vendors reached the Strong Challengers award, but chose to remain anonymous. Their results are included in the report, in order to provide an overview of the performance levels currently available on the market.

AV-Comparatives’ Endpoint Prevention and Response Test is one of the most comprehensive test of EPR products ever performed. It combines prevention and response results with data on total cost of ownership. The products in the test were subjected to 50 targeted attacks, which used a variety of different techniques, to measure prevention, active response and passive response.

Time to prevent & time to respond

The report includes the results of the tests, showing at which stage each product provided active or passive response to each threat. In addition, the time taken to prevent and respond was measured over a period of 24 hours.

Enterprise EPR CyberRisk Quadrant™

AV-Comparatives has developed an Enterprise EPR CyberRisk Quadrant™ that factors in the effectiveness of each product at preventing breaches, the calculated savings resulting from this, the purchase costs of the product, and the product’s operational and accuracy costs. Products were classified in three categories in this regard: Strategic Leader, CyberRisk Visionary, and Strong Challenger.

CyberRisk Insurance

The test considered not only the prevention and response provided by each product, but also the cost of a data breach. This can be USD 4,240,000 according to an IBM study. Using the effectiveness of each product at preventing data breaches, the total cost of ownership was calculated. These results can be used as a basis for cyber-risk insurance policies, amongst other things.
