Vulnerabilities describe possibility.
Runtime behavior shows reality.
Opsonance observes runtime behavior where attacks eventually have to execute: inside processes, containers, workloads, networks, and the Linux kernel.
Ring 0 Visibility
Detect Behavior at the Execution Layer.
AI and modern security tooling are making vulnerability discovery increasingly automated. But a secure build can still become compromised through stolen credentials, supply-chain attacks, configuration errors, zero-days, malicious insiders, or unexpected execution paths.
Every one of those paths eventually has to do something at runtime. It has to execute, request a privilege, touch a file, or open a connection — and each of those actions crosses the syscall interface into the kernel.
Opsonance focuses on what is actually happening in Ring 0: kernel space.
High-Value Signals
Context Over Noise.
More telemetry does not automatically produce better security. Opsonance is designed to prioritize high-value runtime signals and escalate suspicious behavior for deeper investigation.
Four signal domains. One runtime picture.
Process Behavior
Process creation, execution chains, privilege transitions, and unexpected process relationships.
Block fileless malware and unauthorized execution paths in under 1 millisecond directly at Ring-0.
System Activity
Kernel-level runtime events provide visibility into how workloads interact with the operating environment.
Achieve absolute threat visibility while reducing traditional agent compute overhead by up to 90%.
Network Behavior
Identify unexpected runtime communication and suspicious changes in workload network behavior.
Instantly trap lateral movement and data exfiltration without throttling your cloud egress bandwidth.
Workload Context
Correlate runtime signals with node, container, workload, and policy context.
Autonomously deploy ephemeral drop-pods to instantly freeze and extract compromised namespaces.
Orchestrated by Nekron AI
Cognitive Threat Detection.
Running heavy machine learning directly on execution nodes throttles CPU and introduces interdiction latency. Opsonance decouples intelligence from enforcement.
Zero-Latency Enforcement
Nekron handles the computational weight of behavioral analysis asynchronously in the cloud and distills it into lightweight, deterministic policies. Your eBPF Sentinels execute binary decisions at Ring 0 in nanoseconds.
Global Behavioral Immunity
By analyzing deduplicated forensic logs across the fleet, Nekron continuously learns from novel attacks. When a new threat is identified, an updated Global Policy is pushed to every deployment.
Graduated Response
Watch Silently. Strike Instantly.
Rather than blanketing infrastructure with heavy, static inspection, Opsonance observes silently and escalates dynamically — deploying targeted forensic actions and surgical containment exactly where the attack is happening.
When risk escalates, security workload escalates with it.
Observe
Maintain zero-overhead visibility across your infrastructure. Intelligent patrol agents silently monitor baseline activity without impacting workload performance.
Increase Telemetry
Escalate inspection depth the moment an anomaly is detected. The system dynamically captures granular forensic data to analyze suspicious behavior in real time.
Restrict Capability
Dynamically strip non-essential permissions from a suspicious workload. This instantly limits the potential blast radius while allowing safe, core operations to continue uninterrupted.
Block Specific Actions
Surgically neutralize the exact attack vector without disrupting the surrounding environment. Agents instantly deny dangerous system commands or drop malicious network traffic at the edge.
Isolate Workload
Sever the compromised container from your broader infrastructure. The workload is contained for live forensic analysis, physically preventing any lateral movement or data exfiltration.
Revoke Identity
Instantly invalidate the compromised workload’s access credentials. This immediately cuts off its ability to communicate with critical cloud services, APIs, or internal databases.
Kill Process
Terminate malicious execution directly at the source. The system ruthlessly shuts down the offending activity while allowing the rest of the host machine to function normally.
Quarantine Node
Lock down the entire host to prevent a cluster-wide breach. The machine is instantly cordoned off from the network, preserving its exact state for deep incident response and remediation.
From Signal to Intent
Understand What the Event Is Becoming.
An isolated runtime event rarely tells the complete story. A process spawning a shell may be legitimate. A privilege transition may be expected. An outbound connection may be normal.
The threat emerges when individually legitimate actions form an abnormal execution sequence. Opsonance correlates runtime signals across process, identity, filesystem, network, privilege and workload context to determine whether activity is a meaningful deviation from expected behavior.
One event is noise. A sequence is evidence.
Signal Becomes Decision
Behavioral Context
Context Turns Telemetry Into a Decision.
Instead of treating each event as an independent alert, Opsonance builds runtime context around the whole sequence — and that changes the question the system is asking.
The question changes
“Did something unusual happen?”
“What is this behavior attempting to do?”
That distinction lets the system escalate security only when runtime evidence justifies it.
BEHAVIORAL CONTEXT
Every signal is read in context.
Attack Reconstruction
Attacks Are Sequences. Detection Should Be Too.
Modern attacks rarely arrive as a single malicious event. An attacker may begin with a compromised credential, execute a legitimate interpreter, escalate privileges, discover the environment, access sensitive resources and establish an outbound connection.
Each individual action can appear deceptively ordinary. The danger exists in the relationship between them, so Opsonance reconstructs runtime activity as an evolving execution chain.
Instead of producing seven disconnected alerts, the system reasons about how the events relate.
FROM EVENTS TO ATTACK PATH
Seven events. One attack path.
Runtime Attack Graph
See the Path. Stop the Path.
Every event is placed in a continuously evolving runtime attack graph: who acted, what they did, where it happened, when it happened relative to everything else, and why the chain appears to exist. When behavior crosses a defined risk threshold, Opsonance escalates from observation to intervention.
The goal is not another alert in a crowded SOC. It is to establish why the behavior matters before the attack reaches its objective.
Runtime Attack Graph
Defensive Uncertainty
Security the Attacker Cannot Easily Map.
Modern attackers do not only exploit applications. They probe the environment itself: which processes exist, which privileges are available, which controls are present, and which actions produce a response. Automation makes that probing cheap.
Continuous visibility isn't the same as continuous predictability.
Adaptive Control Loop
Adaptation Becomes the Defense.
The attacker may know Opsonance is deployed. The objective is to make it substantially harder to predict:
- when deeper inspection will occur
- where additional inspection will be allocated
- which behavioral signals will trigger escalation
- how the defense will respond to a particular sequence
An attacker can attempt to model a static control. It becomes far harder to optimize against a defense whose observation and response intensity adapt to the environment.
The objective is not to watch everything with equal intensity. It is to respond where risk is actually developing.
