The cybersecurity world received another red flag this month as Infosecurity Magazine reported that a security researcher uncovered a new technique for bypassing SentinelOne, one of the most prominent Endpoint Detection and Response (EDR) solutions on the market.
This isn't just a flaw—it’s another chapter in the story of how “Detect and Respond” is no longer enough.
According to the report, cybersecurity researcher Midas discovered a method to bypass SentinelOne’s behavioral engine entirely, using a stealthy “Bring Your Own Vulnerable Driver” (BYOVD) approach. By exploiting a legitimate but outdated and vulnerable driver (a tactic we’ve seen become increasingly popular), the attacker can execute malicious code without triggering SentinelOne’s defenses.
This is far from an isolated incident. In fact, it is yet another example that even the most well-respected EDR platforms are struggling to keep pace with the growing sophistication of attackers—especially when threat actors now wield malware built with AI, customized exploits, and evasion techniques targeting the very tools meant to stop them.
EDR solutions like SentinelOne work on the premise of “detecting” malicious activity based on signatures, behaviors, and known indicators of compromise. But cybercriminals are no longer playing by predictable rules. The emergence of zero-day exploits, living-off-the-land attacks, and memory-only malware means threats are often completely invisible until it’s too late.
Here’s the real danger: the SentinelOne bypass method didn’t raise a single alarm.
This proves a harsh reality: if your defense depends on detection, you’re always one step behind.
The attacker already has a foot in the door by the time detection kicks in—if it kicks in at all. This delayed response is what makes ransomware, data exfiltration, and system disruption so effective and costly. It’s why even large enterprises with strong IT budgets are still falling victim to attacks, month after month.
At CHIPS, we’ve long championed a shift in mindset: from Detect and Respond to Isolation and Containment.
Instead of reacting to known threats, why not prevent malicious code from ever executing, regardless of whether it's been seen before? That’s the philosophy behind AppGuard—a proven endpoint protection solution used in government and defense environments for over a decade, now available for commercial use.
Unlike traditional EDR tools, AppGuard doesn’t need to “see” malware to stop it. It enforces security policies at the process level, ensuring untrusted or suspicious applications are contained and unable to compromise the system, even if they manage to bypass other tools.
Here’s what AppGuard does differently:
Blocks malicious actions before they occur—even for new or unknown threats
Prevents lateral movement inside networks
Does not rely on signature updates or cloud lookups
Is lightweight, non-intrusive, and easy to deploy
Most importantly, AppGuard would have stopped the type of technique used to bypass SentinelOne, because it doesn’t rely on detecting the activity—it isolates and contains it by default.
The cost of a successful cyberattack goes far beyond ransom payments. It includes downtime, brand damage, legal liability, customer loss, and often years of recovery. Meanwhile, attackers are increasingly targeting small and mid-sized businesses, which may not have the resources or staff to monitor and respond around the clock.
If your cybersecurity plan is still centered on detection, you are leaving your business exposed to the inevitable day when detection fails.
At CHIPS, we believe businesses deserve protection that works even when detection fails. That’s why we advocate for the adoption of AppGuard as part of your cybersecurity stack.
Don’t wait for your business to become another headline. Let us show you how AppGuard’s isolation and containment approach can stop ransomware, malware, and other threats before they do any damage.

You don’t need to detect a breach if you prevent it from happening in the first place. That’s the power of AppGuard.
