Huntress warns AI risks and ransomware shifts demand tested incident response plans in 2026

Huntress has published a report outlining ten endpoint security trends shaping 2026, emphasizing the need for evolved strategies to counter modern threats. The research highlights that traditional antivirus and perimeter-only defenses are no longer sufficient as endpoints, identities, and cloud workloads increasingly overlap. Threat actors are leveraging living-off-the-land attacks to infiltrate environments quietly, requiring organizations to proactively plan for incidents before they occur.

The report stresses that AI-powered endpoint tools are becoming central to security operations but introduce new risks. Huntress notes that agentic AI systems, which automate parts of investigations, must be balanced with human oversight to prevent unchecked decisions. These AI agents can miss novel threats or behave unpredictably if attacked or misused, making human-led validation essential for preventing breaches.

Shifting Threat Landscapes and Ransomware Tactics

Ransomware groups are evolving their methods from single-encryption events to multi-layered extortion campaigns. According to Huntress, attackers now combine data theft, encryption, and public pressure to force higher payouts. This shift means every minute counts after an initial foothold is gained, as attackers may harvest credentials and threaten disclosure long before deploying encryption. Fast detection and strong endpoint visibility are critical to reducing dwell time and stopping incidents before they spiral into downtime.

The Critical Role of Incident Response Planning

Security preparation is just as important as prevention, yet many organizations lack tested incident response plans. Verizon’s 2025 Data Breach Investigations Report found that only 55% of companies have a fully documented IR plan. Furthermore, IBM’s Cost of a Data Breach Report 2025 revealed that just 30% of organizations regularly test those plans. Without clear playbooks for scenarios like ransomware, teams waste precious time figuring out basic response steps during an attack.

Platform Consolidation and Visibility Challenges

As digital environments grow more complex, security teams are moving beyond standalone endpoint detection and response (EDR) to extended detection and response (XDR). Huntress explains that XDR pulls signals from endpoints, email, identities, and cloud workloads to enhance visibility. However, blending security layers under one roof can muddle waters if complexity is not managed properly. Effective consolidation requires clear guidance and real-world expertise to support teams from detection to cleanup.

What should you do?

Organizations should review their current endpoint security strategies to ensure they address the overlap between endpoints, identities, and cloud workloads. Teams need to evaluate their use of AI-powered tools, ensuring that human oversight remains a core component of their security operations. Additionally, businesses should verify that they have a documented and regularly tested incident response plan to handle multi-layered ransomware attacks effectively.

Background: Endpoint detection and response (EDR)

Endpoint detection and response examples include blocking PowerShell scripts that download payloads, isolating devices showing abnormal memory access, and rolling back file changes. These tools monitor behavior, not just signatures, to stop advanced threats that evade standard security controls.

What to do and how to stay safe: Huntress

• Audit your current endpoint security tools to ensure they provide visibility across endpoints, identities, and cloud workloads.
• Review your incident response plan to confirm it is fully documented and includes playbooks for common scenarios like ransomware.
• Schedule regular testing of your incident response plan to ensure teams know their roles during an attack.
• Evaluate your use of AI-powered security tools to ensure human oversight is integrated into decision-making processes.

Frequently asked questions

What are the main endpoint security trends for 2026?

Huntress identifies trends including AI-powered defense, zero trust, human-led threat hunting, and the shift from single to multi-layered ransomware extortion.

How many companies have a tested incident response plan?

According to IBM’s 2025 Cost of a Data Breach Report, only 30% of companies regularly test their incident response plans.

Why is human oversight important for AI security tools?

AI agents can miss novel threats or behave unpredictably if attacked, so human analysts are needed to validate suspicious activity and prevent breaches.
