Overview of DigitalOcean GenAI Platform Guardrails

Generative AI is not a futuristic concept now, but a powerful tool we use in our daily lives. Whether it’s helping a marketer create ad campaigns, a teacher create lesson plans, or a developer build a custom chatbot, generative AI is transforming the way we work, learn, and communicate. Its ability to create text, images, code, and more, with just a simple prompt, is saving people time, boosting creativity, and opening up new possibilities for businesses of all sizes.

Let us take an example of a freelance writer who once used to spend hours researching topics and creating every article outline from scratch. Now, with the help of Gen AI tools, they can instantly create multiple article outlines, understand research papers, and instantly create visual representations of complex topics.

Or think about a customer support team at a growing startup—they can now use an AI-powered assistant to answer common queries, freeing up their team to focus on more complex issues. These are just a few examples of how GenAI is helping people do more with less.

But as exciting as this technology is, it also brings new challenges. Without the right checks in place, AI systems can produce misleading or inappropriate content, unintentionally reflect bias, or even be used in harmful ways. For instance, an AI tool might generate false health advice, or a chatbot could respond rudely if not properly guided. This is where guardrails come in.

Think of Guardrails as the safety features in a car. Just like seatbelts, airbags, and lane assist systems help protect drivers and passengers, guardrails in AI platforms ensure that the technology is used safely, ethically, and responsibly. They prevent misuse, protect user privacy, and make sure the content AI produces is appropriate and aligned with real-world values.

The DigitalOcean GenAI Platform allows you to use popular foundation models and build AI agents powered by GPUs with ease. You can choose between a fully-managed deployment or making direct requests through serverless inference.

Before diving further into the article, it is important to have a basic understanding of the following concepts:

• Generative AI Basics: You should be familiar with what generative AI is and how it works. At a minimum, understand that it involves models like GPT, LLaMA, or Stable Diffusion that can generate text, images, or other media based on a given prompt.

• Foundation Models: Some exposure to foundation models (e.g., GPT-4, LLaMA 3, Mistral) and how they are used as building blocks for AI applications will make it easier to understand how guardrails are applied to them.

• DigitalOcean Account: To follow along or test out examples, you’ll need an active DigitalOcean account. You should also be familiar with basic account navigation within the DigitalOcean Console.

• Agent and RAG Pipelines (Optional but Helpful): If you’ve worked with agents or retrieval-augmented generation pipelines before, you’ll have a head start.

The DigitalOcean GenAI Platform addresses this need through Guardrails—powerful tools that help developers enforce boundaries, protect sensitive data, and prevent misuse of AI agents.

Guardrails are configurable safety controls you can attach to AI agents on the DigitalOcean GenAI Platform. Their core purpose is to detect and respond to sensitive or inappropriate content, either in the input sent to an agent or in its output.

When a guardrail is triggered, it overrides the agent’s default behavior and delivers a safer, predefined response. For example, if an input contains a credit card number, the agent will be blocked from responding as usual and instead issue a cautionary message.

DigitalOcean provides three built-in guardrails that serve specific use cases:

Sensitive Data Detection

• Detects information like credit card numbers, IP addresses, social security numbers, and other personally identifiable information (PII).
• Fully customizable—developers can choose which categories to detect.

Jailbreak Detection

• Blocks attempts to manipulate or bypass the model’s safety mechanisms.
• Useful for preventing prompt injection attacks and misuse.

Content Moderation

• Flags and intercepts content that is offensive, violent, explicit, or hateful.
• Helps keep applications aligned with content policies.

Guardrails can be attached through the DigitalOcean Control Panel using two workflows:

Attach Multiple Guardrails to a Single Agent

Log in to your DigitalOcean GenAI platform, click on the Agents tab to view all your agents, and select the agent to which you want to attach guardrails.

Next, open the Resources tab and scroll down to the Guardrails section and click Add guardrails.

Now, check the boxes next to the guardrails you want to attach, then click Save to confirm your changes.

Attach a Guardrail to Multiple Agents**

To attach a guardrail to one or more agents, go to the DigitalOcean Control Panel and go to your GenAI platform.

Next, select the Guardrail tab.

Open the ellipsis(… ) next to the desired guardrail and select Attach Agent.

The Manage Agents window will open up. Next, select the agents you want to attach and click Update.

You can fine-tune guardrails to align with your use case:

To edit your guardrails, navigate to the DigitalOcean Control Panel. From the left-hand menu, select GenAI Platform, then click on the Guardrails tab to access the guardrails page.

In the Guardrails section, locate the guardrail you’d like to modify. Click the ellipsis (…) next to it and select Edit Guardrail.

You’ll be taken to the guardrail editing page, where you can update various guardrail settings.

On the guardrail editing page, you can modify several settings to tailor the behavior of your guardrail. First, you can update the Name and Description—particularly helpful if you’re editing a duplicated guardrail and want to give it a unique identity.

If the guardrail is of the Sensitive Data Detection type (or a duplicate of one), you can control which specific categories of sensitive information it detects. For example, you might choose to detect credit card numbers, IP addresses, or other data types. By default, all categories are enabled, but you can fine-tune this by clicking Customize categories and selecting only those relevant to your needs. Note that this customization is available only for Sensitive Data Detection guardrails.

You can also modify the Default Agent Response, which is the message the agent displays when the guardrail detects a match in an enabled category. The default response is: “I’m not able to respond to that request, but I can answer other questions. How can I help you with something else?” However, you’re free to replace this with a response more suited to your use case.

Lastly, under Attach Agents, you can link this updated guardrail to specific agents by selecting them from the list. Once all your changes are made, click Update Guardrail to save them.

Duplicating a guardrail allows you to reuse and customize existing guardrail configurations without starting from scratch. On the same guardrail page, you will find the option to duplicate the guardrail. Select that option.

Once you click Duplicate Guardrail, you’ll be taken to the guardrail duplication page where you can customize the following settings:

Name and Description
Enter a unique name and an optional description to identify the duplicated guardrail.

Sensitive Data Detection Categories If the duplicated guardrail is of the Sensitive Data Detection type, you can tailor which data categories it monitors. By default, all categories (e.g., credit card numbers, IP addresses) are enabled.

To customize:

• Click Customize categories
• Check or uncheck the boxes for the specific data types you want to include.

Note: This customization is available only for Sensitive Data Detection guardrails.

Default Agent Response
This is the message that appears when the agent detects a restricted input. The default message is: “I’m not able to respond to that request, but I can answer other questions. How can I help you with something else?” You can replace this with a custom response that better fits your application’s tone or use case.

Attach Agents If you want the duplicated guardrail to be active for specific agents, check the boxes next to the agents you want to assign it to.

Save the Duplicated Guardrail

After configuring all the required settings, click Duplicate Guardrail to finalize and save your new guardrail.

If a guardrail is no longer needed, you can easily delete it from the DigitalOcean Control Panel. Follow these steps to safely remove a guardrail: Log in to the DigitalOcean GenAI account. Open the same Guardrails tab to open the Guardrails management page. Next, locate the guardrail you wish to delete and click the ellipsis icon (…) to the right of that guardrail.

In the Guardrails section, find the guardrail you want to delete. A confirmation dialog will appear asking if you’re sure you want to delete the selected guardrail.

Click Confirm or Delete to permanently remove the guardrail. Note: Deleting a guardrail is irreversible. Once deleted, the configuration and settings cannot be recovered.

Implementing guardrails is not just about turning on a few settings and calling it a day. It is also about thoughtful customization, a continuous refinement process, and staying mindful of your users’ experiences. Here are some best practices to help you get the most out of DigitalOcean’s guardrails features:

1. Customize and Caution: Every AI application is different, and so are its users. When adding or tweaking guardrail settings, it’s important to test with real-world prompts. Try prompts that mimic what your end users might actually type. This will help you understand how the model responds and whether it blocks or allows content appropriately. A too-strict guardrail might stop legitimate use cases, while a too-lenient one could let risky content through. Always strike a balance between safety and usability.

2. Use Duplicates for Flexibility: DigitalOcean’s guardrail system lets you duplicate configurations. For example, you might need stricter content filters for a customer support chatbot, but a more open setup for an internal tool. By duplicating a base configuration, you can customize each version independently, without affecting the original settings.

3. Monitor and Iterate Often: AI keeps changing; hence, after deploying an agent, always make it a habit to review the agent. This gives you valuable feedback. Are you blocking too much content? Not enough? Use these insights to fine-tune detection categories and thresholds over time. Think of it like tuning a radio: small adjustments can make a big difference in clarity and performance.

Following these best practices can help ensure your AI applications remain safe, responsible, and user-friendly while still delivering powerful and engaging experiences.

By setting up clear boundaries, whether that means filtering out harmful content, limiting model behaviour, or adding extra data privacy, you’re not only protecting your users, you’re also building trust. That trust becomes the foundation for more meaningful, impactful AI applications. Guardrails don’t limit creativity—they create space for safe innovation. As you build with GenAI, remember that ethical AI isn’t just about what your model can do—it’s about what it should do. Guardrails help you stay on the right path. Further, DigitalOcean gives you the flexibility to shape your AI to meet your goals without compromising responsibility.
