303,970 Attacks Blocked — Here's What the Data Shows

In June 2026, Sentinel's audit dashboard ticked over to 303,970 total blocked attacks. That's a single server's lifetime counter: every banned IP and every blocked request since Sentinel started running on it.

That's not a crisis. That's normal.

If your Linux VPS is exposed to the internet, this is baseline background radiation. The question isn't whether you're being attacked — you are. The question is whether you can see it happening.

The Raw Number

• 303,970 attacks blocked on one production server (lifetime)

We're deliberately not dressing that up with breakdowns we haven't measured. Queen, Sentinel's central server, doesn't keep a fleet-wide aggregate, so this is one server's honest count. It's enough to make the point: an ordinary server gets probed constantly.

What This Means for Your Server

Blocking hundreds of thousands of attacks is table stakes. The real value is visibility: knowing that the blocking is actually happening, and being able to check it.

Without that, you're either:

1. Flying blind (assuming "no alerts = no attacks"), or
2. Overreacting (e.g., banning entire countries unnecessarily)

Sentinel's Audit dashboard gives you:

• A running record of what has been blocked
• A way to see whether your defences are properly tuned
• A clean audit trail for clients or compliance

How Sentinel Handles It

Here's what happens when an attack hits a Sentinel-monitored server:

1. Detection and blocking – Sentinel integrates with Fail2Ban, CrowdSec and UFW, and automatically installs Fail2Ban jails for the services it detects (sshd, nginx, caddy, apache, mysqld).
2. Cross-fleet sync – Servers report banned IPs to Queen, which correlates them hourly over the last 7 days; other servers in your fleet ban known attackers on their next sync (Enterprise).
3. Bigger actions stay human – Sentinel doesn't ban whole subnets on its own. If a /24 or /16 needs blocking, an admin does it through the AI Chat tool ban_subnet (Enterprise), as an operator-approved action.

Try It Yourself

• Basic tier: Free for 1 server (sign up at sentinel-ai.info/pricing for a one-line install command; installation takes about 2–4 minutes)
• Pro tier: $49/month for 5 servers (adds Database Autopilots and Rate Limiting / Active Shield)
• Enterprise: $149/month for 10 servers (AI Chat, AI Healer, Cross-Fleet IP Reputation)

This isn't about fearmongering. It's about acknowledging reality — and having the tools to handle it.
