M3 Leverages PerimeterX Bot Defender to Block Bots and Optimize Customer Experience

Download Case Study


M3 USA, part of the M3 Group, provides physicians and other healthcare professionals with clinical education the opportunity to participate in market research projects and new career opportunities and provides the life science industry with highly targeted interactive marketing, education, content and research solutions. M3 USA’s service for physicians and other healthcare professionals, MDLinx, provides physicians with up-to-date and relevant clinical information and education.


To provide a high quality of service to advertisers on MDLinx with a minimum of bot traffic, for several years M3 used a bot mitigation solution. Prior to switching to PerimeterX, M3 used a solution with a reverse-proxy-based architecture, meaning that all traffic initially passed through the third-party platform.

Recently, to adapt to the changing needs of the business, M3’s engineering team has begun migrating MDLinx from the existing, monolithic system to a new, redesigned system with a microservices architecture. This change was designed to improve the development process and performance while saving internal resources. M3’s existing reverse-proxy based bot mitigation solution increased latency without providing granular access to log data or control over the proxy behavior.

We didn’t realize how much performance we gave up by having our servers behind the reverse-proxy. After deploying PerimeterX Bot Defender we saw our average response time improve by 400ms, a reduction of over 30%. In addition, PerimeterX accelerated the execution of our vision of modern microservices-based web architecture.

M3 needed a solution that would fit a microservices architecture and accurately block bot traffic while ensuring authorized users received an optimal experience — so they turned to PerimeterX. PerimeterX Bot Defender is a powerful, cloud-based and infrastructure-agnostic bot management solution for detecting and mitigating bots. The solution employs behavior-based analytics to detect anomalies and prevent even the most sophisticated bot attacks.

PerimeterX offered a range of features that were optimally aligned with the team’s requirements:

Flexible architecture: The cloud-based solution was a perfect fit for microservices because it easily integrated with any existing infrastructure, without adding appliances or latency.

Fast deployment and visibility: The solution offered fast and easy deployment with the close support of an experienced onboarding team. The solution offered the M3 team much higher visibility with free access to the logs.

Always available security experts support: The solution came with ongoing security support from the proactive security team.

Bot Defender


By implementing PerimeterX Bot Defender, M3 realized compelling benefits:

Improved performance: Removing the previous solution and deploying Bot Defender immediately improved the user experience by reducing the response time by 400ms — a reduction of over 30%.

Better access to data: The M3 team enjoyed better reporting capabilities of the PerimeterX portal and dashboards along with free access to logs to enable a higher level of independence and control with the cost-savings.

Improved technical support: The level of knowledge and availability of the PerimeterX support team, especially via Slack was a game-changer for the M3 team which cut the time they spent on technical issues.

Since we already needed a reverse-proxy for other purposes, another layer of reverse-proxying just to support bot-mitigation was something we wanted to avoid. Our previous solution required us to use it as a black-box.
