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.
Main Dashboard
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.
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/SSH file manager - browse, upload, download, edit, copy files 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.
AI-Enhanced Autonomous Operations (experimental, optional)
Unified AI engine: Claude, GPT-4, Gemini, Mistral, Groq, LM Studio. Per-host LLM instructions enable background governance loops - "restart /home/bot1/BotService if /home/bot1/tests.log file is older than one day" - 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.
Some fun
