# Deflect One

**v0.78 - AuthSentinel: Multi-Protocol Authentication Intelligence + Enhanced ServerCard UX + First-Run Onboarding**

**Agentless DevOps command center for your entire Linux infrastructure - from one terminal.
No agents. No cloud. No SaaS. Just SSH access - and Deflect One turns that into a complete operations platform: server monitoring, active attack detection, file management, deployments, and more. AI support is available as an optional add-on.**

No agents to install on servers. No cloud. No SaaS. Just SSH access - and Deflect One turns that into a complete operations platform.

From server health monitoring to active attack detection, from deployment orchestration to natural-language command execution via built-in AI - Deflect One combines DevOps observability, cybersecurity response, and LLM-powered decision support into a single, self-contained Python file.

> **Beta** - actively developed.

## Features

### Real-Time Infrastructure Monitoring
CPU, RAM, disk, network I/O, Docker containers, MySQL/PostgreSQL/Redis - across unlimited servers simultaneously. Async-native coroutine pool, near-zero overhead.

![DB Monitor](https://raw.githubusercontent.com/Frytskyy/deflect-one/main/screenshot-deflect-db-monitor.png)
![Connections Viewer](https://raw.githubusercontent.com/Frytskyy/deflect-one/main/screenshot-deflect-connections-viewer.png)

---

### Active Attack Detection & Defense
Live attack radar: malicious IPs, geo-location, timeline. Manages UFW/iptables rules. Defense mode executes bans, restarts, and rate limits autonomously within your policy.

![Ban IP](https://raw.githubusercontent.com/Frytskyy/deflect-one/main/screenshot-deflect-ban-ip.png)

---

### AuthSentinel - Multi-Protocol Authentication Intelligence
**Unified surveillance across SSH, sudo, databases, mail, FTP, and web panels.** Live auth event stream with anomaly detection (brute force, credential stuffing, impossible travel, privilege escalation chains). Session activity forensics: SSH command history, live SQL queries, SMTP envelope inspection. Per-host auth health scoring. sshd hardening auditor with auto-fix. One-click P1 containment workflow: block IP → kill session → disable account → rotate credentials.

---

### Enhanced Server Cards
Health score badges (0-100 with color gradient). Inline Docker container list with status navigation. Hostname pinned to card title. CPU/RAM trend arrows. Keyboard shortcuts and card reordering.

---

### First-Run Onboarding & Host Management
Welcome screen on cold launch: demo mode, add host, or import from `~/.ssh/config`. SSH config sync with credential write-back (backup included). Restore deleted hosts from 7-day archive.

### User & Group Administration
Full Linux user and group management over SSH — create, edit, lock accounts, manage SSH keys, view active sessions and audit details. Safety guards prevent accidental self-lockout.
