In the early days, antivirus solutions operated on a binary detection model, a yes or no approach. However, as threats became more sophisticated, the shift towards behavioral analytics and machine learning became imperative. The complexity of behavioral detection, especially when interacting with volatile processes in memory, underscores the constant innovation required to combat modern threats.

Endpoint security providers can be classified into two broad paths: evolutionary and revolutionary. Some have evolved organically from an antivirus background, steadily incorporating new capabilities over the years. Others have taken a revolutionary approach, starting from an Endpoint Detection and Response (EDR) foundation and dynamically integrating learnings to enhance protection.

The ultimate goal remains consistent: preventing attacks. However, the complexity of modern threats has increased the likelihood of breaches. The transition from binary to behavioral detection methods further complicates the landscape, necessitating a nuanced understanding of the potential risk – it could be good or bad.

Reflecting on the past, I recall the challenges posed by polymorphic viruses in 1991 and the subsequent need for behavioral and machine learning techniques to combat metamorphic threats post the turn of the century. Learning from experience is crucial, leading me to emphasize the importance of solutions that have evolved organically with the threat landscape.

In the last decade, the Endpoint Detection and Response (EDR) market has witnessed significant growth. EDR solutions play a pivotal role when prevention falls short, gathering evidence to identify and understand threats that evade initial detection.

As threats become more complex, the key question is how much of the threat is visible. Enhanced visibility translates to greater confidence in identifying and classifying threats, leading to a broader range of methods for threat detection. Consequently, the integration of EDR and prevention capabilities becomes essential for an effective endpoint solution.

Next time someone dismisses all endpoint solutions as equal, consider the following questions:

1. Visibility: How effectively does each solution capture the entire attack from start to finish? Comprehensive visibility is crucial for both learning and confidence in blocking, especially with behavioral-based techniques.

2. Detection: What proportion of the attack can the vendor actually block? Relying on a single point of prevention may not be the wisest choice. Multiple layers of defense offer a more robust approach.

3. Evolutionary vs. Revolutionary: Consider the source of the endpoint solution. Recent test results, such as those from MITRE, indicate that solutions originating from an EDR background tend to score higher. These solutions leverage learnings quickly, creating a virtuous circle essential for endpoint security.
