Stop attacks before they ever run.
Most of the damage from an attack happens in the instant a harmful program runs — the download starts, the door opens, the files get encrypted. ExecutionProtect makes sure that instant never arrives. It recognizes what a program is actually trying to do and stops the dangerous ones before they can act — including attacks dressed up to look completely harmless.
Part of the 1stProtect platform. One agent. No slowdown.
Direct answer
ExecutionProtect applies runtime guardrails using user-space interception on the single SIGMA engine, so every action is evaluated before execution. It can enforce policy online or offline and coordinate with the on-host MCP gateway to preserve forensic context, reducing false positives while stopping unauthorized behavior at the action layer.
Tools that only sound the alarm after something runs are always a step behind — by then, the payload has downloaded or the damage is done. And modern attackers are good at hiding in plain sight:
Instead of obvious malware, attackers use the legitimate programs already built into Windows to download and run their attacks — so everything looks routine.
A malicious program gets dressed up to look like an ordinary Word document, so an unsuspecting employee opens it without a second thought.
In every case, the thing on the surface looks safe. What gives it away is what it's actually trying to do — and that's exactly what ExecutionProtect watches for.
How it works
ExecutionProtect looks past the file name and the surface to the actual behavior — the true intent behind an action.
Dangerous actions are stopped at the moment of execution, in real time. The legitimate work carries on untouched.
Every block comes with a clear picture of what was attempted and where it came from — so the threat is obvious immediately, not hours later.
One engine. 22 modules.
It runs on the same single SIGMA engine as the rest of 1stProtect — working alongside CallChainProtect to trace where an attack came from, URLProtect to stop the downloads these attacks rely on, and RansomProtect to contain destructive payloads. One agent, one policy, no conflicts — online, offline, or fully air-gapped.
What it stops:
See it in action
A trusted tool turned against you. An attacker uses a legitimate, built-in Windows tool to download a malicious file from the internet. ExecutionProtect blocks it on the spot — and shows you exactly what was attempted and what set it off.
Opening a hole in your defenses. Next, the attacker tries to quietly change the firewall to let a malicious file reach the internet. ExecutionProtect blocks the attempt and flags it, with a clear record of where it came from.
A wolf in a document's clothing. Finally, a malicious program is disguised to look like a normal Word document. The moment someone tries to open it, ExecutionProtect recognizes what it really is and shuts it down.
Deploy without breaking anything
ExecutionProtect ships in Audit Mode by default. Watch exactly what's running across your environment — and exactly what would be blocked — without stopping a single thing. Baseline your environment, whitelist what's legitimate, then flip to Enforcement Mode with one config change.

Built by the people who built the industry
1stProtect's team comes from CrowdStrike, SentinelOne, Check Point, Splunk, Cisco, Oracle, McAfee, Symantec, and NTT Data — the engineers who defined modern endpoint security, now building runtime protection for what comes next.
We'll deploy in Audit Mode and show you, in your own environment, exactly what's running today — then stop the threats before they start.
Product FAQ
ExecutionProtect stops malicious programs before they ever run. It evaluates what a program is actually trying to do — based on its behavior, parent process, and command-line arguments — and blocks dangerous executions at the moment they are attempted, before any payload can run.
Living-off-the-land attacks abuse legitimate built-in Windows tools like certutil, netsh, or mshta to download and run malicious code. ExecutionProtect detects when these tools are being used in ways that deviate from their legitimate purpose and blocks the unauthorized action, regardless of the tool being used.
Yes. ExecutionProtect is behavior-based, not signature-based. It evaluates what a program is trying to do at the moment of execution — so it catches novel malware, AI-generated payloads, and custom attack tools that have never been seen before, without needing a signature to match.
In Audit Mode, ExecutionProtect observes everything running on the machine and records exactly what it would block — without stopping anything. This lets you see your full execution landscape and whitelist legitimate programs before switching to Enforcement Mode.
For your security & engineering team
ExecutionProtect performs pre-execution prevention on the user-space SIGMA engine, evaluating process behavior, parent-child lineage, and command-line arguments independent of binary signature or reputation — neutralizing living-off-the-land abuse of native tools (certutil, netsh), masqueraded double-extension executables, and unauthorized tooling. Each prevention is recorded by the on-host MCP AI Investigator and streams to your SIEM/SOAR (Splunk, Datadog, Elastic) via JSON, gRPC, MCP, or Syslog. <1% CPU, real-time enforcement, 100% offline-capable, with Audit and Enforcement modes.
