In today’s threat landscape, attackers increasingly target the very tools designed to stop them. As a result, organizations need to rethink endpoint security from the ground up. A recent survey highlights that many organizations rely on disparate point security solutions that inadvertently expand the attack surface by introducing new vulnerabilities. It also reveals a growing confidence gap: more than half of security professionals report dissatisfaction with their endpoint defenses, even as 61% of organizations experienced a third-party data breach in the past 12 months.
This disconnect is driving demand for a more cohesive and resilient approach. Security leaders are calling for integrated solutions that reduce complexity rather than amplify it. Lenovo, in partnership with SentinelOne and Absolute Security, is addressing this shift with a unified model that combines AI-driven threat defense with firmware-embedded persistence, ensuring that even when security agents are attacked or disabled, protection is automatically restored and continuously enforced.
The defenders have become target
For years, endpoint security strategies have focused primarily on detection: deploying antivirus, advancing endpoint detection and response (EDR) and assuming those defenses would remain operational once installed. That assumption no longer holds.
Today’s adversaries are not just attempting to evade detection; they are deliberately targeting the security infrastructure itself. Modern attack campaigns increasingly include techniques designed to disable or bypass endpoint protection platforms (EPPs), such as stopping agents, exploiting configuration weaknesses and abusing legitimate system tools to blend into normal activity.
This evolution reflects a simple but powerful realization: it is often easier to neutralize the security tool than to evade it. Once an endpoint agent is disabled, visibility collapses, alerts cease and attackers gain freedom of movement.
This is the essence of endpoint agent tampering—the deliberate effort to disable, corrupt, or remove the software responsible for detecting and responding to threats. And it has become one of the most effective entry points for modern cyberattacks.
How endpoint agents are compromised
The techniques used to tamper with endpoint agents vary, but they share a common objective: blind the system before executing the primary attack. In a hybrid, AI‑accelerated world, the endpoint is the attack surface. If endpoints are compromised, AI governance, zero trust and cloud controls are undermined.
Most attacks begin with privilege escalation, often achieved through phishing, credential theft, or exploitation of unpatched vulnerabilities. With administrative access, attackers can interact with security tools just as IT operators would—stopping services, uninstalling agents, or altering configurations.
Another common tactic is “living off the land”, where adversaries leverage legitimate tools such as PowerShell, WMI, or native system utilities to disable security controls. Because these tools are trusted and widely used, malicious activity can appear routine, complicating detection.
More advanced techniques include safe mode abuse, where systems are rebooted into states that prevent security agents from loading and bring-your-own-vulnerable-driver (BYOVD) attacks, which exploit signed but vulnerable drivers to gain kernel-level access and terminate protections.
The failure of “Configured and Assumed” security
The targeting of defensive systems exposes a deeper flaw in traditional security models: the assumption that once protection is deployed, it remains effective.
In environments defined by remote work, distributed endpoints and constant change, that assumption breaks down. Devices roam across networks, go offline, are reimaged, or fall out of compliance. Agents drift, fail, or disappear altogether.
This creates a widening gap between “configured and assumed” security and what modern environments require: continuously verified and actively enforced protection.
The challenge is no longer just stopping threats, it is ensuring that the tools designed to stop them are always present, always functional and capable of recovering from attack.
Lenovo’s Aanswer: Unified endpoint security and resilience
To meet this challenge, Lenovo has developed a unified endpoint approach that combines two complementary capabilities: ThinkShield XDR, powered by SentinelOne and Absolute Security.
Together, they form a continuous detect–protect–recover loop, designed to stop attacks and ensure that protection itself cannot be permanently disabled.
AI-driven defense with SentinelOne
At the core of Lenovo’s solution is ThinkShield XDR, powered by SentinelOne. This platform unifies prevention, detection, response and recovery into a single AI-driven agent that operates directly on the endpoint.
Unlike traditional tools that rely on cloud connectivity or human intervention, SentinelOne’s agent makes decisions locally, at machine speed. It can detect malicious behavior, blocks ransomware in real time and can automatically roll systems back to a known-good state after an attack.
This autonomous model reduces response times and alleviates pressure on overstretched security teams. It also ensures protection remains effective even when devices are offline or operating in constrained or hostile environments.
However, as powerful as this capability is, it still operates at the operating system layer—making it a potential target for tampering.
Absolute Security: Resilience below the OS
This is where Absolute Security adds a critical layer of resilience. Unlike traditional software agents, Absolute is embedded directly into device firmware at the point of manufacture. This creates a hardware-anchored control plane that persists even if the operating system is wiped or the device is reimaged.
If an attacker disables or removes the SentinelOne agent, Absolute detects the change and automatically reinstalls it—without human intervention. This self-healing capability ensures security controls are continuously restored, closing the window of exposure. In doing so, it transforms EPP bypass from a catastrophic failure into a non-persistent, self-correcting event.
A self-healing security architecture
Together, SentinelOne and Absolute – delivered through Lenovo’s ThinkShield portfolio – create a layered architecture in which each component reinforces the other.
- SentinelOne delivers real-time threat detection, response and automated recovery.
- Absolute ensures those capabilities remain present and operational, even under direct attack.
Combined, they deliver:
- Firmware-to-cloud protection, anchoring security below the OS while extending visibility across endpoints and cloud environments
- Self-healing controls, automatically repairing or reinstalling critical security applications
- Continuous validation, ensuring protections are always present and functioning
- Faster recovery, restoring devices to a trusted state with minimal disruption
The result is stronger endpoint resilience, fewer security gaps and always-on protection.
From detection to durability
The broader implication is a fundamental shift in how organizations must think about security.
Detection alone is no longer sufficient. Security controls must be durable—able to withstand attacks, recover automatically and continuously prove their effectiveness.
Lenovo’s ThinkShield framework reflects this evolution, embedding security across the entire device lifecycle—from supply chain integrity to firmware-level persistence to AI-driven endpoint protection.
The future of endpoint security
As attackers continue to evolve, targeting both systems and defenses themselves, resilience is becoming the defining requirement of modern endpoint security.
The question is no longer whether endpoint agents will be attacked. It is whether they will survive.
By combining SentinelOne’s autonomous, AI-driven defense with Absolute’s firmware-embedded persistence, Lenovo makes a compelling case for a new model—one where security is deployed, continuously verified, self-healing and fundamentally harder to break.
In a landscape where the defender has become the target, that shift may be the difference between visibility and silence, between containment and compromise.
