What is Next-generation Antivirus (NGAV)?

Next-generation antivirus (NGAV) is an endpoint security technology that uses advanced detection methods to identify and stop malware, suspicious behavior, and fileless threats. Organizations use Next-generation antivirus (NGAV) to improve protection beyond traditional signature-based antivirus tools. By analyzing behavior, attack patterns, and execution activity, NGAV helps security teams detect threats that may evade older antivirus approaches.

Why do organizations use NGAV?

Traditional antivirus mainly relies on known malware signatures. That approach can miss new malware, modified files, and attacks that avoid writing malicious files to disk.

Organizations use NGAV to:

  • Detect unknown malware
  • Identify suspicious behavior
  • Reduce fileless attack risks
  • Improve endpoint protection
  • Strengthen malware prevention

This makes NGAV useful in environments where attackers frequently change tools and techniques.

How does Next-generation antivirus work?

NGAV evaluates activity on endpoints rather than relying only on static file signatures. It analyzes how files, scripts, processes, and system behaviors interact.

A typical workflow includes:

  • Monitoring endpoint activity
  • Analyzing files and processes
  • Identifying suspicious behavior
  • Blocking or flagging threats
  • Generating security alerts
  • Supporting further investigation

This approach helps detect threats based on behavior and context.

What threats can NGAV help detect?

NGAV focuses on endpoint-level threats that may bypass traditional antivirus tools.

Threat type Security concern
Unknown malware New or modified malicious files
Fileless malware Attacks using memory or trusted tools
Ransomware Unauthorized encryption activity
Malicious scripts Suspicious PowerShell or script behavior
Exploit activity Attempts to abuse software weaknesses

These detections help security teams respond faster to endpoint threats.

What challenges affect NGAV deployments?

NGAV improves endpoint protection, but it still requires proper configuration, monitoring, and response workflows. Common challenges include:

  • Tuning detection policies
  • Reducing false positives
  • Managing endpoint coverage
  • Investigating alerts quickly
  • Coordinating response actions

Security teams often combine NGAV with XDR, EDR, SIEM, and threat intelligence to improve detection and response.

Connecting prevention with investigation

Prevention tools help stop threats, but security teams still need context when suspicious activity appears on endpoints. Analysts must understand what happened, which device was affected, and whether additional action is required.

Hexnode XDR can support endpoint investigations through:

  • Centralized incident review
  • Visibility into suspicious endpoint activity
  • Endpoint scans during investigations
  • Context gathering from affected devices
  • Remote terminal access when appropriate
  • Agent update support across managed endpoints

These capabilities help teams investigate endpoint security events that may involve malware or suspicious behavior.

FAQs

No. NGAV focuses mainly on preventing and detecting endpoint threats. EDR focuses more on investigation, telemetry, and response after suspicious activity appears.

In many environments, NGAV replaces or extends traditional antivirus by using behavior-based and advanced detection methods instead of relying only on signatures.

Yes. NGAV can help detect fileless attacks by analyzing behavior, script execution, memory activity, and unusual use of trusted system tools.
