Key points
- AI agents require human oversight to prevent unpredictable behavior or hijacking by threat actors.
- Ransomware groups are shifting toward multi-layered extortion involving data theft and public pressure.
- Most organizations lack fully tested incident response plans, complicating recovery from endpoint breaches.
The short version
- Endpoint security in 2026 requires balancing AI automation with strict human control and oversight.
- Ransomware tactics have evolved to include triple extortion, increasing the urgency of rapid detection.
- Incident response planning remains a critical gap, with many firms failing to test their preparedness.
The details
Endpoint security challenges have shifted significantly from traditional malware campaigns of the past decade, according to research published by Huntress. Modern threats target the overlapping areas of endpoints, identities, and cloud workloads, rendering perimeter-only defenses insufficient. Threat actors increasingly employ living-off-the-land techniques to operate quietly within environments. To counter these fast-moving risks, organizations must evolve their strategies and prepare for incidents proactively rather than relying solely on prevention.
The integration of AI into security operations introduces new complexities that demand careful management. While AI tools offer advanced capabilities, they also bring security and ethical risks that organizations must address. The focus for 2026 is on maintaining control over autonomous systems to ensure decisions do not go unchecked. AI is becoming embedded in daily security tasks, requiring partners to be intentional about system selection and implementation to avoid unintended consequences.
Agentic AI systems, which analyze large data volumes and automate investigations, pose specific risks if they are poorly trained or lack guardrails. These agents can miss novel threats or behave unpredictably when attacked or misused. Attackers may target these agents as non-human identities, attempting to hijack their functions. Consequently, AI works best when paired with human oversight rather than serving as the sole decision-maker in security operations.
Ransomware tactics are also evolving, moving beyond simple encryption to multi-layered extortion strategies that heighten business risk and public fallout. Many groups now combine data theft, encryption, and public pressure to force higher payouts. This shift means attackers may quickly harvest credentials and threaten disclosure long before deploying encryption, making fast detection and strong endpoint visibility critical for minimizing damage and downtime.
The context
Despite the availability of security measures, many businesses lack a clear and tested incident response plan. According to Verizon’s 2025 Data Breach Investigations Report, only 55% of companies have a fully documented IR plan. IBM’s Cost of a Data Breach Report 2025 revealed that just 30% regularly test those plans. Without a defined plan, organizations lose valuable time figuring out roles and communication protocols during an attack, allowing small incidents to spiral into chaos.
Security teams are increasingly looking beyond standalone endpoint detection and response to extended detection and response platforms. XDR pulls in signals from endpoints, email, identities, and cloud workloads to enhance visibility. However, blending security layers under one roof can introduce complexity that muddies the waters if not managed correctly. Organizations must ensure that consolidation enhances rather than obscures their ability to detect and respond to threats effectively.
What to watch
- The rise of agentic AI in security operations and the associated risks of unpredictable behavior.
- The shift from single-encryption ransomware to multi-layered extortion tactics involving public disclosure.
- The gap in incident response preparedness, with many organizations failing to test their plans regularly.
- The consolidation of EDR into XDR platforms and the potential for increased complexity in security operations.
What to do
- Verify that AI security tools have clear guardrails and are not acting autonomously without human review.
- Ensure incident response plans are documented and tested regularly to reduce confusion during actual events.
- Monitor for signs of living-off-the-land attacks that may bypass traditional perimeter defenses.
- Review endpoint visibility tools to ensure they cover identities and cloud workloads, not just devices.
What it means for organisations
Security leaders must evaluate whether their current AI tools provide sufficient oversight and control. Teams usually need to verify that human analysts validate automated decisions to prevent errors. Check whether incident response plans include playbooks for common scenarios like ransomware and remote access breaches. Ensure that cross-functional teams, including legal and communications, are briefed on their roles. Assess whether your visibility tools cover the full scope of endpoints, identities, and cloud workloads to detect multi-layered attacks.
Background: Encryption
Encryption is the process of converting plain text into ciphertext using an algorithm and a key. It prevents unauthorized access to data at rest and in transit. Without the correct decryption key, the information remains unintelligible, protecting privacy and integrity against interception or theft.

What to do and how to stay safe: Huntress
- Review AI security tools to ensure they operate with human oversight and clear guardrails.
- Test incident response plans regularly, including playbooks for ransomware and remote access incidents.
- Monitor endpoint activity for living-off-the-land techniques that bypass traditional defenses.
- Verify that detection platforms cover endpoints, identities, and cloud workloads for comprehensive visibility.
