+# DigitalOcean and EspoCRM
+
+DigitalOcean is a cloud platform that provides scalable infrastructure, including virtual servers (Droplets), storage, networking, and other cloud services. In this guide, we will use a DigitalOcean Droplet to deploy and run a self-hosted EspoCRM instance.
+
+1. Sign up on the [official DigitalOcean website](https://cloud.digitalocean.com/registrations/new)
+
+2. Create a Droplet
+
+![Create a droplet](../../_static/images/administration/digital-ocean/droplet-create.png)
+
+3. Choose a datacenter region that is convenient for you. The recommended OS is Ubuntu or Debian.
+
+![Choose a datecenter](../../_static/images/administration/digital-ocean/datacenter.png)
+
+4. We recommend a Droplet plan with at least 1 GB of RAM.. Higher plans may provide a smooother user experience.
+
+![Choose a droplet plan](../../_static/images/administration/digital-ocean/droplet-plan.png)
+
+5. Attach an SSH key or create a password, although using a password provides lower security. Add Payment Method and complete the Droplet creation.
+
+![Create an SSH key](../../_static/images/administration/digital-ocean/ssh-key.png)
+
+> [!NOTE]
+> At this step, you can proceed with registeting a domain on any preffered domain provider and bind it to the Public IPv4 address shown in the Droplet menu.
+
+![puplic IPv4](../../_static/images/administration/digital-ocean/public-ip.png)
+
+6. Now, log in to your server using the "Web Console" button or any other convenient way (e.g., a terminal) as the root user.
+
+![web-console position](../../_static/images/administration/digital-ocean/web-console.png)
+
+7. Right after you log in to your server you can already download the installation script and run it with a singlt command:
+```
+wget -N https://github.com/espocrm/espocrm-installer/releases/latest/download/install.sh
+sudo bash install.sh
+```
+During installation process, the system will prompt you to choose appropriate SSL protocol and enter a domain name, if available.
+
+It's also possible to run the installer with all necessary preset, for example:
+```
+wget -N https://github.com/espocrm/espocrm-installer/releases/latest/download/install.sh
+sudo bash install.sh -y --ssl --letsencrypt --domain=my-espocrm.com --email=email@my-domain.com
+```
+
+All available prompt options can be foud [here](installation-by-script.md#available-options)
+
+After a successful installation, the login credentials, including the URL that you can use to access EspoCRM, will be shown in the terminal.

+# Fail2ban
+
+Fail2Ban is a security tool that monitors system logs for repeated failed authentication attempts and temporarily blocks suspicious IP addresses. It helps protect the server against brute-force attacks.
+
+The following steps demonstrate how to install and check that Fail2Ban is correctly configured on your server.
+
+1. Install
+```
+sudo apt update
+sudo apt install fail2ban -y
+```
+2. Create the SSH jail configuration
+Create the file:
+```
+sudo nano /etc/fail2ban/jail.d/sshd.local
+```
+Add the following configuration:
+```
+[sshd]
+enabled = true
+port = ssh
+filter = sshd
+backend = systemd
+
+findtime = 10m
+maxretry = 5
+bantime = 1h
+```
+3. Test the configuration
+Run:
+```
+sudo fail2ban-client -t
+```
+You should see:
+```
+OK: configuration test is successful
+```
+4. Restart Fail2Ban
+```
+sudo systemctl restart fail2ban
+sudo systemctl enable fail2ban
+```
+5. Check the jail
+```
+sudo fail2ban-client status
+```
+Check SSH jail details:
+```
+sudo fail2ban-client status sshd
+```
