Deflect One

Agentless DevOps command center for your entire Linux infrastructure — from one terminal.

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. Core features are stable, new screens added regularly.

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.

---

🛡 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.

---

🤖 AI-Enhanced Autonomous Operations

Unified AI engine: Claude, GPT-4, Gemini, Mistral, Groq, LM Studio. Per-host LLM instructions enable background governance loops — "restart MySQL if slow-query rate exceeds 10/min" — running 24/7 without you watching.

---

💬 Natural-Language Command Terminal

Ctrl+A → describe what you want in plain English → Deflect One translates to CLI/SSH/Bash and executes it.

---

📦 Package & System Management

Full apt integration: view available updates, security patches, and install packages — across all hosts from one screen.

---

🐳 Docker & Services

Manage containers, images, and systemd services without leaving the terminal.

---

📁 File Manager

Dual-panel SFTP file manager — browse, upload, download, edit, copy between hosts. Midnight Commander style.

---

📋 Log Aggregation & Journal Viewer

Cross-host regex log search and live journalctl tailing with 8 preset tabs.

---

✉️ Email Monitor

MTA queue monitoring, account overview, error rates — across all hosts.

---

⚙️ Fleet & Bulk Operations

Manage your entire server fleet: bulk DevOps commands, SSH key rotation, host management.

---

🔧 More Tools

Cron & systemd timer management, network reconnaissance, script runner, config export.
