What to look for in a next-generation antivirus (NGAV)

Next-generation antivirus (NGAV) was designed to close security gaps left by legacy solutions. Traditional signature-based antivirus struggles against modern threats such as zero-day malware, fileless attacks, and advanced ransomware.

When choosing an NGAV, prioritize features powered by Artificial Intelligence (AI) and Machine Learning (ML) for behavioral analysis and pattern recognition. This approach helps detect and block previously unknown threats.

A modern NGAV should also integrate with EDR and XDR platforms to improve visibility, correlation, and incident response.

Core NGAV capabilities

When evaluating vendors, look for:

1. AI and Machine Learning (ML)

The ability to process large data sets, detect complex attack patterns, and identify malicious behavior in real time, ideally using Indicators of Attack (IOAs) and exploit mitigation.

1. Unknown threat protection

Defense against known and unknown threats (especially zero-day attacks) through behavioral analytics instead of relying only on static signatures.

1. Policy customization

Support for allowlists and blocklists so security teams can adapt controls to business applications and internal risk policies.

1. Cloud-native architecture

Faster deployment, continuous updates, and lower endpoint impact, while keeping protection consistent even when devices are offline.

Security trends for 2025

NGAV aligns with broader trends:

• XDR (Extended Detection and Response): correlation across email, network,

cloud, identity, and endpoint telemetry.

• Ethical AI in cyber defense: responsible autonomous detection,

prioritization, and containment.

• Automation with playbooks: rapid, repeatable containment and response

actions to minimize dwell time.

What to expect from a top-tier solution

A strong NGAV should be:

• Lightweight and fast on endpoints
• Not signature-dependent as the only detection model
• Effective while offline
• Deeply integrable with EDR/XDR and the rest of your security stack

In practice, the better the integration with your security ecosystem, the higher your overall prevention and response maturity.
