Bitdefender Sweeps AV-Comparatives EPR Test, Achieving 100% Breach Prevention and Lowest TCO

The newly released AV-Comparatives EPR Comparative Report 2025 for Endpoint Prevention and Response (EPR) has validated a key strategy in cybersecurity: prevention-first is the winning approach. The report places Bitdefender GravityZone at the forefront of the industry, leading across the board with superior breach prevention and the lowest Total Cost of Ownership (TCO).

Unmatched Prevention Capabilities

In the rigorous evaluation, which tested 12 security vendors against 50 attack scenarios, Bitdefender distinguished itself by achieving a 100% active response rate in the critical first phase of an attack—endpoint compromise and foothold. Bitdefender GravityZone was the only vendor to successfully block every single one of the tested attacks before they could progress further. This exceptional performance underscores the effectiveness of its multi-layered security architecture, reinforcing the idea that the most effective defense is a proactive one.

Lowest Total Cost of Ownership

Beyond efficacy, Bitdefender GravityZone was also named the most cost-effective solution, securing the lowest Total Cost of Ownership (TCO) among all evaluated vendors. The report calculates TCO over a five-year period for a hypothetical 5,000-endpoint environment.

The cost savings are largely attributed to Bitdefender’s high prevention rate, which dramatically reduces the financial and operational costs associated with responding to and remediating breaches. Furthermore, the solution incurred zero costs for operational accuracy and workflow delay, ensuring security operations run smoothly without disrupting legitimate business activities. This combination of high capability and low cost placed Bitdefender at the top-right of the EPR CyberRisk Quadrant.

Exceptional Enterprise-Level Security without the Enterprise-Level Cost

The most compelling aspect of the report is the analysis of cost-efficiency. Bitdefender GravityZone achieved the lowest Total Cost of Ownership (TCO) among all evaluated vendors, delivering true enterprise-grade security without the typical exorbitant price tag.

According to the report, Bitdefender’s five-year TCO per endpoint was calculated to be nearly 10 times (9.8) lower than the average of all other vendors. This dramatic cost saving is a direct result of its superior prevention, as stopping threats early eliminates the costly process of incident response, recovery, and prolonged business disruption. Furthermore, the solution earned a perfect score for operational accuracy, incurring zero costs from false positives or workflow delays that often plague other security products. This combination of top-tier capability and low expense placed Bitdefender at the highly sought-after top-right of the EPR CyberRisk Quadrant.

Leading in Advanced EDR Technology

While prioritizing prevention, the platform did not compromise on detection and response. Bitdefender GravityZone demonstrated robust capabilities in the EDR phase, achieving a 98% detection success rate, significantly surpassing the average of its competitors. The report also highlighted the sophistication of its underlying technology, noting that Bitdefender is the sole vendor to incorporate all 14 advanced EDR technologies analyzed, underscoring its foundation as a comprehensive and future-proof security solution.

The results of the AV-Comparatives 2025 EPR test clearly demonstrate that Bitdefender GravityZone delivers an optimal balance of protection and value, offering organizations a highly effective, unified, and economically sensible security platform.
