Start with essential security controls: enable automatic updates, require multi-factor authentication, configure firewall rules, regularly back up data, and develop an incident response plan. These measures align with CISA guidance and can be implemented on providers like Vultr.
Drive Cybersecurity Strategy from the Top
For small businesses, leadership commitment is the foundation of a strong security posture. CISA’s Cyber Essentials emphasize that owners and managers must drive cybersecurity strategy, investment, and culture, treating it as a business risk. This means understanding how much of your operations depend on IT and building relationships for threat information. Develop clear cybersecurity policies in consultation with IT resources.

Protect Your Systems with Updates and Hardening
Knowing what’s on your network is critical—maintain inventories of hardware and software. Enable automatic updates for all operating systems and third-party applications, and implement security configurations. Remove unsupported or unauthorized hardware and software. Use email and web browser security settings to block spoofed content, and create application allow lists so only approved software runs. Vultr provides firewall groups to centrally manage inbound and outbound traffic rules across multiple instances, simplifying network protection.
- Maintain hardware and software inventories
- Enable automatic updates for OS and third-party apps
- Implement security configurations and remove unauthorized assets
- Use email/browser security settings
- Create application allow lists

Secure Access with Multi-Factor Authentication and Least Privilege
Control who accesses your digital workplace. Maintain inventories of network connections, including user accounts and vendors. Leverage multi-factor authentication (MFA) for all users, starting with privileged, administrative, and remote access users—CISA explicitly recommends this as a first step. Grant access based on need-to-know and least privilege, use unique passwords, and have policies for user status changes. These practices reduce the risk of unauthorized entry.
- Require MFA for all users, especially admins and remote access
- Grant least privilege access
- Use unique passwords for every account
- Maintain inventory of network connections

Back Up Data and Protect It
Data is critical to operations, so learn what information resides on your network and how it’s protected. CISA advises establishing regular automated backups and redundancies of key systems. Protect backups with physical security, encryption, and offline copies. Employ backup solutions that automatically and continuously back up critical data and system configurations. Vultr offers snapshots and block storage that can be used for backup strategies.
- Maintain inventory of critical/sensitive information
- Establish regular automated backups and redundancies
- Protect backups with physical security, encryption, and offline copies
- Continuously back up critical data and configurations

Prepare for Incidents with a Response Plan
Limit damage and quicken restoration by developing an incident response and disaster recovery plan. Outline roles and responsibilities, test the plan often, and use business impact assessments to prioritize recovery. Know who to contact for help—outside partners, vendors, government/industry responders. Establish internal reporting structures to detect and contain attacks. Use in-house containment measures to limit incident impact.
- Develop and test an incident response plan
- Prioritize systems with business impact assessments
- Identify external contacts for help
- Establish internal reporting for attacks

Who Should Follow This Checklist and Who Should Reconsider
This checklist is designed for small businesses and freelance operators who manage their own VPS instances and want a practical security baseline aligned with government guidance. It is ideal if you have some technical ability to configure firewalls, enable MFA, and set up backups. If your operations are highly regulated or you lack in-house technical skills, consider managed security services. Prices, features, and terms for providers like Vultr should be verified directly, as they change over time.
