A poorly configured server can expose API keys, sensitive data and connected services to attackers. Common risks include weak SSH settings, open ports, misconfigured Docker containers and leaked environment variables.<\/p>\n\n\n\n<p>The good news is that securing a self-hosted AI agent does not require enterprise-level infrastructure. By following a few proven VPS hardening practices, you can significantly reduce your attack surface and improve reliability. In this guide, you&#8217;ll learn how to secure your VPS, harden Docker deployments, protect secrets, control network access, monitor suspicious activity and build a reliable backup and recovery strategy for Hermes Agent.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-is-hermes-agent-security-important-on-a-vps\">Why is Hermes agent security important on a VPS?<\/h2>\n\n\n\n<p>Hermes Agent is designed to handle autonomous agent workflows, browser automation, messaging apps and complex tasks with minimal manual input. To perform these actions, the agent often gets access to API keys, env files, messaging platforms, vector stores and internal tools. This level of access makes security a critical part of every Hermes setup.&nbsp;<\/p>\n\n\n\n<p>If attackers compromise a working agent, they may gain access to conversation history, reusable skills, file management systems and connected services like a Telegram bot or MCP server. In some cases, a compromised container runs malicious commands, steals a GitHub token or spreads across other tools connected to the same infrastructure.&nbsp;<\/p>\n\n\n\n<p>Securing yourself hosted Hermes environment helps reduce the blast radius of attacks. It also protects persistent memory, procedural memory and self-improving skills stored on your own infrastructure. Strong security controls improve your overall security posture and help keep Hermes running safely across long-term AI agent workloads.&nbsp;<\/p>\n\n\n\n<p>Also read: <a href=\"https:\/\/www.bluehost.com\/blog\/hermes-agent-self-hosted\/\">What is Hermes Agent? A self-hosted AI agent guide for developers<\/a>\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-recommended-secure-architecture-for-hermes-agent-nbsp\"><strong>Recommended secure architecture for Hermes agent<\/strong>&nbsp;<\/h2>\n\n\n\n<p>A secure Hermes setup should isolate services, limit public exposure and protect AI agent workloads from unauthorized access. The safest approach is to run Hermes Agent on VPS hosting with Docker, a reverse proxy and firewall protection.&nbsp;<\/p>\n\n\n\n<p>Secure VPS architecture overview&nbsp;<\/p>\n\n\n\n<p>A standard Hermes Agent architecture includes:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>VPS hosting\u00a0<\/li>\n\n\n\n<li>Docker containers\u00a0<\/li>\n\n\n\n<li>Reverse proxy like NGINX or Traefik\u00a0<\/li>\n\n\n\n<li>Firewall rules\u00a0<\/li>\n\n\n\n<li>Private container networking\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Docker isolates Hermes services, browser automation tools and messaging gateways inside separate containers. A reverse proxy handles HTTPS traffic and SSL certificates. Firewall rules restrict unnecessary access.&nbsp;<\/p>\n\n\n\n<p>Use private Docker networks for internal communication. This prevents direct exposure of vector stores, env file data and backend services. HTTPS encryption also protects API keys, conversation history and messaging platforms during data transfer.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-why-docker-is-better-than-direct-host-installation-nbsp\"><strong>Why Docker is better than direct host installation<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Docker improves security by isolating processes inside separate containers. If one container runs malicious code, the attack is less likely to affect the full VPS environment.&nbsp;<\/p>\n\n\n\n<p>Docker also simplifies rollback and recovery. You can redeploy older container versions if a Hermes update, new skills package or setup wizard change causes issues.&nbsp;<\/p>\n\n\n\n<p>Container isolation reduces the attack surface as well. You can apply dropped capabilities, restrict root access and control resource usage for AI agent workloads.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-recommended-vps-specifications-nbsp\"><strong>Recommended VPS specifications<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Your VPS plan depends on the size of your Hermes setup and agent workflows.&nbsp;<\/p>\n\n\n\n<p>Recommended baseline:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1\u20132 vCPU cores\u00a0<\/li>\n\n\n\n<li>2\u20134 GB RAM\u00a0<\/li>\n\n\n\n<li>NVMe SSD storage\u00a0<\/li>\n\n\n\n<li>Ubuntu LTS or Debian\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Advanced workloads with browser automation, persistent memory, reusable skills and multiple messaging apps may require higher RAM and CPU resources.&nbsp;<\/p>\n\n\n\n<p>NVMe storage improves file management, vector store performance and conversation history retrieval speed.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-ports-and-services-you-should-expose-nbsp\"><strong>Ports and services you should expose<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Expose only required services to the internet.&nbsp;<\/p>\n\n\n\n<p>Recommended setup:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Port 443 for HTTPS\u00a0<\/li>\n\n\n\n<li>Restricted SSH access\u00a0<\/li>\n\n\n\n<li>Private internal container networks\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Avoid exposing Docker ports, databases or MCP server services publicly.

Create a non-root user<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Avoid running Hermes setup tasks as the root user. Create a separate sudo account for daily management and disable direct root access later.&nbsp;<\/p>\n\n\n\n<p>Example commands:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>adduser hermesadmin\u00a0\nusermod -aG sudo hermesadmin\u00a0<\/code><\/pre>\n\n\n\n<p>Using a non-root account limits the blast radius if attackers gain access to the server.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-harden-ssh-access-nbsp\"><strong>2. Harden SSH access<\/strong>&nbsp;<\/h3>\n\n\n\n<p>SSH is one of the most targeted services on a VPS hosting environment. Weak SSH settings can expose your own infrastructure to brute-force attacks and unauthorized admin access.&nbsp;<\/p>\n\n\n\n<p>Recommended SSH hardening steps:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Disable password authentication\u00a0<\/li>\n\n\n\n<li>Use SSH keys only\u00a0<\/li>\n\n\n\n<li>Change the default SSH port\u00a0<\/li>\n\n\n\n<li>Restrict login access\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Example SSH configuration:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>PermitRootLogin no\u00a0\nPasswordAuthentication no\u00a0<\/code><\/pre>\n\n\n\n<p>SSH keys provide stronger protection than passwords and improve the overall security posture of your Hermes Agent VPS.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-configure-firewall-rules-nbsp\"><strong>3. Configure firewall rules<\/strong>&nbsp;<\/h3>\n\n\n\n<p>A firewall helps control which services are publicly accessible. Allow only the ports required for Hermes Agent runs and messaging gateway traffic.&nbsp;<\/p>\n\n\n\n<p>Recommended UFW setup:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ufw allow 22\u00a0\nufw allow 443\u00a0\nufw enable\u00a0<\/code><\/pre>\n\n\n\n<p>Port 443 handles HTTPS traffic.

Prevent secrets from appearing in logs&nbsp;<\/h3>\n\n\n\n<p>Logs often contain more sensitive information than expected. Debug output can accidentally expose API keys, access tokens, conversation history or authentication details.&nbsp;<\/p>\n\n\n\n<p>To reduce risk:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Redact sensitive values before logging\u00a0<\/li>\n\n\n\n<li>Disable verbose debug logging in production\u00a0<\/li>\n\n\n\n<li>Review application and container logs regularly\u00a0<\/li>\n\n\n\n<li>Prevent secrets from being written to monitoring systems\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Keeping credentials out of logs strengthens your security posture and helps protect long-running Hermes Agent workloads.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-network-security-and-access-control-nbsp\"><strong>Network security and access control<\/strong>&nbsp;<\/h2>\n\n\n\n<p>Network security helps prevent unauthorized access to Hermes Agent, connected tools and sensitive data. The goal is simple: expose only what users need and keep everything else private.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-restrict-public-exposure-nbsp\"><strong>1. Restrict public exposure<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Every public-facing service increases risk.

Automate the process to ensure critical data is protected consistently.&nbsp;<\/p>\n\n\n\n<p>Follow these best practices:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Schedule daily backups\u00a0<\/li>\n\n\n\n<li>Encrypt backup files\u00a0<\/li>\n\n\n\n<li>Store copies in a separate location\u00a0<\/li>\n\n\n\n<li>Retain multiple recovery points\u00a0<\/li>\n<\/ul>\n\n\n\n<p>For teams running Hermes Agent VPS Hosting, automated backups help protect memory files, execution logs and long-running agent workflows while reducing operational risk.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-test-your-recovery-process-nbsp\">3. Test your recovery process&nbsp;<\/h3>\n\n\n\n<p>A backup is only useful if it can be restored successfully. Regular testing helps identify corrupted files, missing data or incomplete backup procedures before an actual incident occurs.&nbsp;<\/p>\n\n\n\n<p>At a minimum:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Verify backup integrity\u00a0<\/li>\n\n\n\n<li>Test database restoration\u00a0<\/li>\n\n\n\n<li>Confirm environment files load correctly\u00a0<\/li>\n\n\n\n<li>Practice full recovery workflows\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Testing reduces downtime and helps ensure Hermes Agent runs normally after a recovery event.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-create-a-rollback-strategy-nbsp\">4. Create a rollback strategy&nbsp;<\/h3>\n\n\n\n<p>Software updates, configuration changes and new skills can occasionally introduce issues. A rollback plan allows you to restore a stable environment quickly.&nbsp;<\/p>\n\n\n\n<p>Consider:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>VPS snapshots before major changes\u00a0<\/li>\n\n\n\n<li>Container image versioning\u00a0<\/li>\n\n\n\n<li>Configuration backups\u00a0<\/li>\n\n\n\n<li>Database recovery points\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Snapshot-based recovery and container rollback procedures make it easier to recover from failed deployments while keeping agent infrastructure, messaging gateways and connected tools available.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-test-if-your-hermes-agent-vps-is-secure-nbsp\">How to test if your Hermes agent VPS is secure&nbsp;<\/h2>\n\n\n\n<p>Securing your server is only half the job. Regular testing helps confirm that your Hermes setup remains protected as you add new skills, model providers, messaging platforms and agent workflows. Use the following checks as part of your Hermes Agent VPS security guide and ongoing security maintenance process.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-check-open-ports-nbsp\">1. Check open ports&nbsp;<\/h3>\n\n\n\n<p>Review all listening services on your VPS and verify that only required ports are exposed.&nbsp;<\/p>\n\n\n\n<p>Run:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ss -tulpn\u00a0<\/code><\/pre>\n\n\n\n<p>Look for unexpected services, exposed Docker ports or publicly accessible tools. Databases, vector store services, MCP server instances and internal containers should not be reachable from the internet. This is especially important when running Hermes Agent, browser automation workloads and messaging gateways on the same server.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-verify-firewall-protection-nbsp\">2. Verify firewall protection&nbsp;<\/h3>\n\n\n\n<p>Your firewall should expose only the services needed for normal operations.&nbsp;<\/p>\n\n\n\n<p>Confirm that:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>HTTPS traffic is allowed\u00a0<\/li>\n\n\n\n<li>SSH access is restricted\u00a0<\/li>\n\n\n\n<li>Internal services remain private\u00a0<\/li>\n\n\n\n<li>Unused ports are blocked\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Whether you install Hermes Agent on a new VPS plan or migrate from a home server, firewall validation is a basic hygiene task that helps strengthen your overall security posture.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-test-ssh-hardening-nbsp\">3. Test SSH hardening&nbsp;<\/h3>\n\n\n\n<p>SSH remains one of the most common attack targets on self-hosted infrastructure.&nbsp;<\/p>\n\n\n\n<p>Verify that:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Password authentication is disabled\u00a0<\/li>\n\n\n\n<li>SSH key authentication works correctly\u00a0<\/li>\n\n\n\n<li>Root access is restricted\u00a0<\/li>\n\n\n\n<li>Fail2Ban blocks repeated login attempts\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Proper SSH hardening helps protect admin access, file management systems, environment files and other sensitive components of your agent infrastructure.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-audit-docker-container-permissions-nbsp\">4. Audit docker container permissions&nbsp;<\/h3>\n\n\n\n<p>Review container settings regularly to ensure services are running with the minimum privileges required.&nbsp;<\/p>\n\n\n\n<p>Check for:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Privileged containers\u00a0<\/li>\n\n\n\n<li>Unnecessary root access\u00a0<\/li>\n\n\n\n<li>Missing dropped capabilities\u00a0<\/li>\n\n\n\n<li>Writable filesystems where read-only access is sufficient\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Container isolation is particularly important when Hermes Agent runs browser automation, image generation workflows, web search tasks or integrations with a Telegram bot, Home Assistant and other tools.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-5-run-a-basic-vulnerability-scan-nbsp\">5. Run a basic vulnerability scan&nbsp;<\/h3>\n\n\n\n<p>Security scanning helps identify weaknesses before they become exploitable.&nbsp;<\/p>\n\n\n\n<p>Useful tools include:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lynis\u00a0<\/li>\n\n\n\n<li>Docker Bench Security\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Regular scans can uncover:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Misconfigurations\u00a0<\/li>\n\n\n\n<li>Outdated dependencies\u00a0<\/li>\n\n\n\n<li>Weak permissions\u00a0<\/li>\n\n\n\n<li>Exposed services\u00a0<\/li>\n<\/ul>\n\n\n\n<p>As your Hermes setup grows to include reusable skills, persistent memory, procedural memory, messaging apps, model providers and custom integrations, periodic security audits help reduce the blast radius of potential threats and keep your AI agent workloads running securely.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-common-hermes-agent-security-mistakes-to-avoid-nbsp\">Common Hermes agent security mistakes to avoid&nbsp;<\/h2>\n\n\n\n<p>Many security incidents are caused by simple configuration mistakes rather than sophisticated attacks. Avoiding the following issues can significantly improve the security posture of your Hermes Agent deployment.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-running-containers-as-root-nbsp\">1. Running containers as root&nbsp;<\/h3>\n\n\n\n<p>Running a container with full root access gives attackers more control if the service is compromised. This increases the blast radius and can expose the host system, sensitive files and connected services.&nbsp;<\/p>\n\n\n\n<p>Instead:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Run containers as non-root users\u00a0<\/li>\n\n\n\n<li>Apply the principle of least privilege\u00a0<\/li>\n\n\n\n<li>Use dropped capabilities where possible\u00a0<\/li>\n<\/ul>\n\n\n\n<p>This is especially important for AI agent workloads that interact with browser automation tools, messaging platforms and external APIs.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-exposing-docker-ports-publicly-nbsp\">2. Exposing Docker ports publicly&nbsp;<\/h3>\n\n\n\n<p>A common mistake during the initial setup is exposing Docker ports directly to the internet. While this may simplify testing, it can leave internal services vulnerable to unauthorized access.&nbsp;<\/p>\n\n\n\n<p>Avoid exposing:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Databases\u00a0<\/li>\n\n\n\n<li>Vector store services\u00a0<\/li>\n\n\n\n<li>MCP server endpoints\u00a0<\/li>\n\n\n\n<li>Container management interfaces\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Use a reverse proxy and private container networks instead. This creates a safer environment for Hermes Agent, the Hermes gateway and other supporting tools.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-storing-api-keys-in-git-repositories-nbsp\">3. Storing API keys in git repositories&nbsp;<\/h3>\n\n\n\n<p>Hardcoding API keys, access tokens or credentials inside repositories is one of the fastest ways to create a security risk.&nbsp;<\/p>\n\n\n\n<p>Never store:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>API keys\u00a0<\/li>\n\n\n\n<li>GitHub token credentials\u00a0<\/li>\n\n\n\n<li>New token values\u00a0<\/li>\n\n\n\n<li>Password manager exports\u00a0<\/li>\n\n\n\n<li>Sensitive env file data\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Use environment variables, Docker Secrets or a dedicated secret manager to protect credentials connected to model providers, messaging apps and other services.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-ignoring-vps-security-updates-nbsp\">4. Ignoring VPS security updates&nbsp;<\/h3>\n\n\n\n<p>Unpatched systems remain one of the most common attack vectors. Delaying updates can leave your VPS hosting environment exposed to known vulnerabilities.&nbsp;<\/p>\n\n\n\n<p>Keep the following updated:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Operating system packages\u00a0<\/li>\n\n\n\n<li>Docker components\u00a0<\/li>\n\n\n\n<li>Reverse proxies\u00a0<\/li>\n\n\n\n<li>Security tools\u00a0<\/li>\n\n\n\n<li>Application dependencies\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Whether you are running Hermes on a home server or Bluehost Hermes Agent VPS Hosting, regular updates help protect persistent memory, conversation history and long-running agent workflows.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-5-using-weak-ssh-credentials-nbsp\">5. Using weak SSH credentials&nbsp;<\/h3>\n\n\n\n<p>Weak passwords and poorly secured SSH configurations make it easier for attackers to gain admin access.&nbsp;<\/p>\n\n\n\n<p>Follow these best practices:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use SSH keys instead of passwords\u00a0<\/li>\n\n\n\n<li>Disable root login\u00a0<\/li>\n\n\n\n<li>Enable Fail2Ban\u00a0<\/li>\n\n\n\n<li>Restrict access to trusted IPs\u00a0<\/li>\n\n\n\n<li>Rotate credentials regularly\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Strong SSH security helps protect your own infrastructure, Hermes config files, reusable skills, execution logs and other critical components that keep a working agent running securely.&nbsp;<\/p>\n\n\n\n<p>Also read: <a href=\"https:\/\/www.bluehost.com\/blog\/hermes-agent-memory\/\">How Hermes Agent Memory Works: Architecture, Providers and Plugins<\/a>\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-hermes-agent-vps-security-checklist-nbsp\">Hermes agent VPS security checklist&nbsp;<\/h2>\n\n\n\n<p>Use this checklist to verify that your Hermes Agent deployment follows core security best practices.

Running Hermes Agent inside its own container is generally safer than installing everything directly on the host operating system. Containerization also makes it easier to deploy new skills, test updates and roll back changes if needed.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780916916837\"><strong class=\"schema-faq-question\">What ports should I expose for Hermes Agent?\u00a0<\/strong> <p class=\"schema-faq-answer\">Only expose the services required for public access. Most deployments need HTTPS on port 443 for the Hermes gateway. Keep databases, vector store services, MCP server instances and other internal services private. Whether you connect Hermes to messaging platforms, a Telegram bot or a different tool, avoid exposing internal containers directly to the internet.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780916949501\"><strong class=\"schema-faq-question\">How do I securely store API keys on a VPS?\u00a0<\/strong> <p class=\"schema-faq-answer\">Store API keys in environment variables, Docker Secrets or a dedicated secret manager. Never hardcode credentials in source code, Hermes config files or Git repositories. This includes credentials for a Hermes model, Claude Code integrations, a single API endpoint or external model providers. Regularly rotate credentials and revoke unused tokens.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780916966828\"><strong class=\"schema-faq-question\">Should I use a VPN for remote administration?\u00a0<\/strong> <p class=\"schema-faq-answer\">Yes, A VPN such as WireGuard or Tailscale helps protect SSH and admin access. This is especially important when running Hermes on your own infrastructure instead of a local machine or home network. Combining VPN access with IP allowlisting provides stronger protection for long-running agent workloads.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780916984600\"><strong class=\"schema-faq-question\">How often should I update Docker containers and VPS packages?\u00a0<\/strong> <p class=\"schema-faq-answer\">Apply critical security updates as soon as possible. Review Docker images, dependencies and VPS packages regularly. Before deploying updates, check release notes and test changes in a staging environment. Following the same pattern for updates helps maintain a stable and secure setup.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780917001660\"><strong class=\"schema-faq-question\">What tools can I use to audit VPS security?\u00a0<\/strong> <p class=\"schema-faq-answer\">Popular tools include Lynis, Docker Bench Security and Fail2Ban. You should also validate open ports, review firewall rules and scan container images regularly. As your Hermes setup grows to include Hermes skills, browser automation, a built in learning loop, reusable workflows and integrations from the Skills Hub or Nous Portal, routine audits become even more important for maintaining a strong security posture.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Secure your self-hosted Hermes Agent with VPS hardening, Docker security,
