Endpoint Detection & Response for Linux

GhostShield EDR. Ring 0-Level Protection for Linux Servers.

eBPF-based enterprise security. Instant threat containment with zero performance impact.

Licensing Plans Documentation

Plug & Play installation. Compatible with all major Linux distributions (eBPF kernel). Immediate protection without restarting the server.

Features

Comprehensive Shield against Modern Threats

The eBPF engine decides at the exact moment of the syscall, neutralizing everything from automated scripts to extortion attacks.

I/O Guillotine Anti-Ransomware

Instant blocking of processes attempting to exfiltrate data or perform mass encryption.

behavioral detection

Quarantine Vault Anti-Droppers

Malicious files are surgically isolated, stripped of execution permissions, and cryptographically hashed, neutralizing malware before it acts.

isolation + SHA-256

Memory & Process Isolation Anti-Fileless

Tactical blindness (hidepid=2) and eBPF hooks prevent code injection and hide your infrastructure from attackers.

hidepid=2 + eBPF hooks

Self-Integrity Anti-Tampering

Ring 0 shielding with SHA-512 boot validation. Not even unauthorized root access can disable the shield without triggering automatic restoration.

SHA-512 manifest

Cryptojacking Block Anti-Miners

Prevents attackers from installing silent cryptocurrency miners that hijack your CPU and drive up your server infrastructure costs.

execve hooks

Defense against Scanners & AIs Anti-Exploit

Autonomous AIs and network scanners constantly look for vulnerabilities. GhostShield neutralizes payloads and reverse shells the millisecond they attempt to invade.

Why Ring 0 changes the outcome

An agent running only in user space watches the attack; one that decides inside the kernel can stop it.

  • The decision happens on the syscall path. The hostile call is blocked before it completes, not reported after the file has already been encrypted.
  • Native eBPF engine, no kernel module. The code passes the kernel verifier before it runs: it cannot crash the system or reach memory outside its contract.
  • Cost per call, not per packet. The engine measures the behaviour of whoever is already inside the host — the attacker does not dictate your CPU usage.
  • Local JSONL telemetry. Every event is one line written on the host, timestamped in UTC, read by a read-only dashboard.
  • Resource isolation. Critical processes run in a reserved CPU slice, so exhaustion caused by a hostile process never takes down what has to stay up.
Kernel — decision and containment Ring 0

eBPF hooks on execution, memory, file I/O and network egress. They stop the hostile action at the point of the call.

Agent — correlation and response Ring 3

Collects kernel events, scores behaviour, runs the quarantine and writes the forensic trail.

Dashboard — read only read-only

A local interface with no write path at all: watching the incident never alters the defence.

Why GhostShield?

Why choose GhostShield EDR?

Two numbers decide an EDR purchase: what it costs in machine resources, and what it costs when the attack happens.

Performance

Which tool reacts faster to a Ring 0 attack? A legacy EDR consuming 2 GB of RAM, or GhostShield with a mere 2 MB footprint?

Written in pure Rust and eBPF, GhostShield delivers maximum lethality against malware with zero impact on server performance.

Agent memory footprint under normal operation.

Cost & visibility

A ransomware ransom destroys operations. Absolute prevention costs the equivalent of a monthly coffee per server.

Gain real-time tactical visibility of neutralized threats with the integrated Argos Dashboard, designed for demanding SysAdmins.

  • Read-only dashboard: watching the incident never alters the defence
  • Every event is a JSONL line on the host itself, timestamped in UTC
  • Counters per defence: I/O, memory, quarantine and anti-tampering

Transparency & Scope

To ensure maximum efficiency and a zero footprint, GhostShield acts strictly as a behavioral Ring 0 Host-Based EDR.

  • Not a Network Firewall: We do not perform DDoS mitigation or SYN Flood containment. Our protection begins the moment the threat touches the operating system.
  • Not a Traditional Antivirus: We do not perform slow disk scans looking for old signatures. GhostShield intercepts syscalls in real-time at the exact millisecond of the attack.
