Acts instantly and effectively against ransomware, data exfiltration and sophisticated attackers.
ByteJames Ranger showcases the future of endpoint protection: a kernel‑free solution that also blocks remote ransomware attacks — a persistent blind spot even for Gartner Magic Quadrant leaders.
While AI‑driven platforms promise adaptability, they're routinely bypassed — attackers shape malicious code to look statistically benign and evade detection.
Our patent‑pending technology detects threats generically, without signatures, cloud dependency, or connectivity — ideal for air‑gapped environments.
We eliminate kernel components entirely, avoiding the system instability behind incidents like the CrowdStrike global outage.
While Microsoft is building its Windows Resilient Security Platform, ByteJames delivers today — the only protection that addresses the root cause of 90% of successful ransomware breaches, without compromising system reliability.
End Ransomware.
Ransomware still disrupts businesses daily — even after a decade of security advances and AI innovation.
Our lightweight, on‑device ransomware protection works autonomously without relying on threat intelligence or AI, delivering universal file protection, automatic recovery, and securing both local and remote data against encryption attacks, no matter the file size or type.
Stop Data Exfiltration.
With double extortion now standard practice, attackers steal files before encrypting them. When the ransom is not paid, they publish your stolen data.
Our autonomous, on‑device technology detects and automatically blocks data exfiltration without signatures or ongoing management, securing intellectual property and limiting breach impact even when attackers gain network access.
Unified Algorithm.
Today, over 90% of ransomware attacks originate from unmanaged or compromised devices
(Microsoft
).
Preventing both local and remote ransomware attacks has never been more critical.
Our patent‑pending technology not only blocks these threats but also detects data exfiltration — all with a single, unified algorithm.
Kernel-Free.
Microsoft's Windows Resiliency Initiative transitions security providers to user mode for greater stability.
ByteJams Ranger delivers kernel-free ransomware and data exfiltration protection, showcasing our adaptability to evolving security needs.
ByteJams Ranger is the first solution to natively produce high-fidelity telemetry fully aligned with the OCSF standard, making it compatible with, and enriching, existing telemetry pipelines.
Ranger protects critical assets from threats like ransomware and data exfiltration, making it an ideal sensor for Managed Service Providers (MSPs), Security Operations Centers (SOCs), in-house threat response teams, and Managed Detection and Response (MDR) providers. The platform delivers standardized, enterprise-grade endpoint visibility with minimal deployment and operational friction.
ByteJams is a contributor to the Open Cybersecurity Schema Framework.
Protect applications from manipulation and memory-level attacks — without kernel drivers, code injection, or API hooks. Ranger preserves performance and integrity while stopping advanced attacks before they succeed.
ByteJams B.V. is a Dutch cybersecurity startup founded by an industry veteran with over 20 years of experience, whose technologies successfully protect more than 50 million devices worldwide. ByteJams introduces a patent‑pending, kernel‑free architecture that safeguards system stability and preserves peak application performance, while delivering next‑generation protection against human‑led cyberattacks. Unlike traditional solutions — including AI‑based defenses — ByteJams not only detects threats but disrupts the fundamental techniques attackers rely on. Leveraging deep expertise in Windows internals and data flow, ByteJams enables real‑time interception of ransomware encryption and data exfiltration, even from previously unknown threats — setting a new standard for future‑proof cybersecurity.
