Managing cybersecurity and remote access in small and medium-sized enterprises has become increasingly complex. With the widespread adoption of remote work and the dispersal of corporate resources across local servers, public clouds, and SaaS applications, maintaining a traditional security perimeter is no longer viable. In this scenario, the Zero Trust model (never trust, always verify) has consolidated as the standard of protection. However, its deployment and daily management demand a technical and configuration effort that many SMEs cannot easily afford.
To address this challenge, Cloudflare recently presented Cloudflare One stack, a set of tools and capabilities designed to allow artificial intelligence (AI) agents to assist in the planning, deployment, and management of security environments. This announcement represents a relevant step in cybersecurity automation, opening the door for SMEs to configure and monitor their Zero Trust access policies in a more agile way and with less reliance on complex manual processes.
However, this evolution raises practical questions: what is the real scope of these new functions? How can businesses that need to protect their networks and servers leverage them? And, above all, what are the limits and precautions to keep in mind when integrating AI into corporate security management?
What is Cloudflare One stack?
Cloudflare One stack is not a standalone product, but a specialized library of agent skills and infrastructure components that integrates with organizations' AI agents. This technology allows virtual assistants to interact directly and securely with Cloudflare's security platform.
The main capabilities introduced by this set of tools include:
- Automated migration from traditional systems: The system allows AI agents to process configuration files from legacy SASE providers (such as Zscaler or Palo Alto Networks) and map them to equivalent directives and rules within Cloudflare One, simplifying the transition to the Zero Trust model.
- AI-adapted programming interface: Through a typed interface and specialized servers, agents can query the active configuration of the company's account, detect potential inconsistencies, and apply recommended changes following a validated workflow.
- Network diagram interpretation: Agents can read and generate network diagrams in visual format, facilitating the design of the access architecture and streamlining audit tasks.
These skills rely on the Agent Cloud infrastructure that Cloudflare has developed for isolated AI execution environments (Sandboxes), ensuring that agent code runs securely without exposing critical organization credentials.
What changes for Zero Trust?
To understand the relevance of this development, it is helpful to recall the principle of Zero Trust. Under this approach, no user, device, or connection is trusted automatically simply by being inside the physical office network or office VPN. Every access attempt must be verified continuously before authorization is granted.
This is key for SMEs when managing:
- Remote access to servers and databases.
- Secure publishing of internal web applications and ERPs.
- Connections to remote desktops (RDP).
- Access of external collaborators and vendors to specific company resources.
With Cloudflare One stack, the technical administrator or the external IT consultant can use AI as an assistant to structure these verification policies, ensuring they are defined consistently according to actual business needs.
What can change for an SME?
For a small or medium-sized company without a large cybersecurity department, AI-assisted management tools can bring practical benefits:
- Faster deployments: It reduces the time needed to set up new secure access tunnels and configure filtering policies.
- Detection of human errors: AI agents can audit existing policies and alert about incomplete configurations or overly permissive access rules.
- Guided migrations: Helps SMEs that want to abandon traditional network architectures for a more flexible Zero Trust model.
- Clear documentation: Facilitates generating updated reports and diagrams of how company security is organized.
It is worth noting that these advantages will depend on the availability of functions in the corresponding plans and on the AI agent software being properly integrated into the company's management infrastructure.
AI does not replace a secure architecture
Although automation offers great potential, it is fundamental to understand that an AI-based tool cannot fix structural security flaws by itself. AI acts on the rules and guidelines provided to it.
Therefore, automation does not magically resolve issues such as:
- Former employee accounts that remain active in the system.
- Corporate or personal devices without security patches or antivirus.
- Lack of multi-factor authentication (MFA) on user access.
- Legacy internal applications exposed to the Internet without prior protection.
- Overly broad access permissions granted to users for convenience.
Artificial intelligence does not correct poor organization; on the contrary, it can propagate errors and vulnerabilities faster across the entire network. AI must be an administrative assistant, not a substitute for strategic planning or expert human supervision.
Zero Trust is not just another VPN
One of the main mistakes in SMEs is treating Zero Trust solutions (such as Cloudflare Access) as if they were a conventional VPN. While a traditional VPN usually gives full access to the corporate network upon validating the initial connection, Zero Trust works in a completely different way:
- Selective access: The user only sees and interacts with the specific application or server they need to work on, keeping the rest of the infrastructure hidden.
- Continuous verification: It checks not only the user and password, but also whether the device complies with corporate security policies (for example, if it has an updated operating system or active encryption).
- Detailed logging: Monitors and records every connection and action performed, providing a complete audit trail.
Therefore, integrating AI into Cloudflare management helps refine and monitor these selective connections, making the management of a secure environment more viable for small IT teams.
Which businesses does it make sense for?
Adopting these assisted technologies and the Zero Trust model is particularly advisable for companies with:
- Workforces with employees who work remotely on a regular basis or on the move.
- Organizations with multiple sites or offices that need to share internal resources privately.
- Professional firms, agencies, and clinics that handle highly confidential information (medical data, payroll, accounting).
- Hybrid infrastructures combining physical servers, cloud servers, and SaaS applications (such as Microsoft 365 or Google Workspace).
What to review before deploying
Before moving forward with the adoption of Cloudflare Zero Trust or using automation tools like Cloudflare One stack, SMEs must audit their current state:
- Identity directory: Ensure the list of users and passwords is clean and updated.
- MFA implementation: Enable multi-factor authentication without exception across all access profiles.
- Resource inventory: Clarify which servers, databases, and web applications need to be available remotely.
- Least privilege policies: Define in advance which employee needs access to which resource, avoiding universal access.
- Technical supervision: Establish a human review protocol to validate any configuration proposal suggested or generated by an AI assistant.
