nexus-fleet 1.2.1

Nexus Fleet — agent/manager/cli/dashboard keamanan endpoint (ala-Wazuh, ringan, stdlib-only)

Nexus Fleet

Lightweight, developer-first security platform for endpoints, servers, and web apps. Agent · Manager · CLI · Dashboard — a Wazuh-style architecture you can pip install.

---

Overview

Nexus Fleet lets a central Manager monitor many endpoints through a lightweight Agent, generating prioritized, MITRE ATT&CK–mapped alerts — while your security data stays inside your own network (offline-first). It pairs the proven Wazuh model (FIM, log monitoring, SCA, vulnerability detection, active response) with developer-first detections for modern web stacks (Laravel, Next.js, Nginx) that traditional SIEMs miss.

The agent is pure-Python (stdlib only) — deploy it on any host with Python 3.8+, no heavy runtime.

Why Nexus Fleet

• Offline-first — telemetry never leaves your LAN; ideal for compliance and on-prem.
• Developer-aware — detects Laravel APP_DEBUG, exposed .env, weak DB creds, leaked NEXT_PUBLIC_* secrets, source-map exposure, and parses Laravel/Nginx/auth logs.
• Lightweight & simple — single-command install; no cluster, indexer, or agent runtime to manage.
• Actionable — every alert carries a severity level (0–15), MITRE technique, and a remediation step.
• Founder-friendly — a 0–100 security posture score for network, server, and website.

Installation

With pip (recommended):

pip install nexus-fleet

With npm (Node wrapper around the Python engine):

npm install -g nexus-fleet

Both install the umbrella command nexus plus five standalone commands: nexus-manager, nexus-agent, nexus-cli, nexus-dashboard, nexus-license. Requires Python 3.8+ on the host.

nexus --version       # prints: nexus 1.2.1   (verify the install on any terminal)
nexus --help          # list sub-commands

Quick Start

# 1. Central server (also serves the dashboard at http://<host>:8765/)
nexus manager run --host 0.0.0.0 --port 8765
nexus manager info                       # prints enrollment key + admin token

# 2. On each endpoint
nexus agent enroll --host <manager> --port 8765 --key <ENROLL_KEY> --labels prod,web
nexus agent start                        # runs as a daemon (see deploy/ for service files)

# 3. Administration
nexus cli                                # interactive SOC console (network & web menus)
nexus cli --token <ADMIN_TOKEN> alerts   # list alerts (rule engine + MITRE)
nexus cli --token <ADMIN_TOKEN> report   # consistent report (schema nexus.report/v1)

Each nexus <sub> form maps to the matching standalone command (nexus manager run ≡ nexus-manager run). Use whichever you prefer.

Run as a boot-time service using the units in deploy/ (systemd / Windows Task Scheduler).

Editions

	Free	Pro	Enterprise
Agents (seats)	2	seat-based (default 50)	Unlimited
Detection rules	Core	Full (FIM, web audit, SCA, vuln)	Full
Sigma import · Active Response	—	✓	✓
Web/app audit · Reports · Posture score	Limited	✓	✓

Licensing is enforced by Ed25519-signed tokens (nexus-license). Without a license, the Manager runs in Free mode (2 agents). A Pro token is seat-based — it allows up to its seat count (default 50) of agents to enroll; Enterprise is unlimited. One token unlocks the desktop GUI, the CLI, and Fleet on the same device (~/.nexus/desktop_license.txt). Apply a token to the Manager with NEXUS_LICENSE=<token-or-file> or nexus cli apply-license. Contact the vendor for licensing.

Security Model

Area	Protection
Transport	HMAC-SHA256 per-agent message signing; optional TLS / mTLS for the Manager API
Authentication	Enrollment key for agents; admin token with RBAC roles (admin / analyst / read-only)
At rest	Sensitive event fields encrypted at rest (Fernet); SQLite in WAL mode
Integrity	Replay/clock-skew protection on signed messages; tamper-evident audit log
Privacy	Offline-first — telemetry is stored locally; nothing is sent to the internet
Scope	For ethical, authorized security testing on systems you own or may assess
