Keep every Linux server locked down.
Bots try to break into Linux servers all day, guessing passwords and looking for software nobody updated. BurstLayer blocks them, keeps your packages patched and tells you in plain words when something needs a look.
Every server with a public address gets knocked on, day and night.
Most break-ins are not clever. They are automated tools trying common passwords over SSH, the remote login most Linux servers use, or looking for a package with a known flaw. BurstLayer shuts those doors and keeps them shut.
What attacks Linux servers
These six account for most of the trouble we see on Linux machines. Each one is stopped before it becomes a break-in.
Password guessing over SSH
Bots try thousands of usernames and passwords on your remote login. We block them after a few failures and help you switch to key-based logins.
Outdated packages
A library or service with a published flaw is the easiest way in. We find it and install the fix during a quiet hour.
Ports left open
Databases and admin panels that answer the whole internet by mistake. We spot them and close them to everyone but you.
Cryptominers
Hidden programs that use your server to mine coins and slow everything down. We notice the unusual load and stop them.
Changed system files
Intruders try to hide by swapping out system tools. We check important files and tell you the moment one changes.
Web shells
A small file uploaded through a weak website that works like a remote control for an attacker. We find it and lock it away.

How BurstLayer protects your Linux servers
A small agent runs on each server and reports to BurstLayer. It uses very little memory and never asks you to open a new port.
Blocks break-in attempts
Repeated failed logins are blocked at the network edge, so they never reach your server.
Installs security fixes
Updates are tested and installed in a window you choose, with an automatic undo if a service stops.
Watches every login
You see who logged in, from where and what they ran, and get a message when something looks wrong.
Fixes weak settings
Root logins over SSH, password-only access and missing firewalls are corrected with one approval.
Checks important files
Changes to system tools and startup scripts are flagged within seconds.
Spots strange behaviour
Sudden CPU spikes, unknown programs and odd outgoing traffic are looked into by our security AI.
Protect a server with one command.
Run this on Ubuntu, Debian, Red Hat, Rocky, AlmaLinux, Amazon Linux or a similar server. It installs the agent and links it to your account.
$ curl -fsSL https://get.burstlayer.com | sudo shFound Ubuntu 24.04 on web-01Installing the BurstLayer agent✓ Linked to your workspace✓ 14 packages have security fixes waiting. Review them in your dashboard.
You can read the install script before you run it, and remove the agent at any time with one command.
- 01
Run the command
The agent installs in under a minute and starts in watch-only mode, so nothing changes yet.
- 02
Review what we found
Your dashboard lists open ports, missing fixes and recent login attempts, explained in plain words.
- 03
Choose what we fix
Approve fixes one by one, or let BurstLayer handle routine updates on its own.
The products behind it
Each one works on its own. Together they cover Linux servers, from the network edge to the last line of code.
Questions, answered.
Which Linux versions are supported?+
Current releases of Ubuntu, Debian, Red Hat Enterprise Linux, Rocky Linux, AlmaLinux, Amazon Linux and SUSE. Older versions can still be watched even when we can no longer patch them.
Will the agent slow down my server?+
It is built to stay small. The heavy work, such as reading through logs, happens on our side instead of on your machine.
Can BurstLayer restart my services?+
Only if you allow it. By default we ask before any restart, and you can set quiet hours for routine updates.
Could I get locked out of my own server?+
The agent never changes how you log in without your approval, and every change it makes can be undone from the dashboard.
