7 AI Security Tools to Prepare You for Every Attack Phase

AI security tools key takeaways:
  • The most effective AI security tools identify and eliminate potential attack paths before incidents occur, rather than simply responding to threats after they materialize. 

  • Most tools only cover part of the ML pipeline. Robust AI security requires aligning tools to each attack phase.

  • There are five important criteria for evaluating AI security tools, including integrations with cloud and DevOps pipelines and compliance support.

What’s the best AI security tool? 

It’s a tricky question to answer. If you Google it, you’ll see a heavy focus on security operations (SecOps) tools powered by AI but not nearly enough information on SecOps tools for AI applications. 

Of course, it’s important to be up-to-speed on AI-powered cyber security tools, but you also need to know your options for securing AI. That said, we’ll share three popular tools and their broad artificial intelligence security capabilities, plus five more open-source tools and how they align with specific machine learning (ML) attack phases.

What to look for in an AI security solution

There are many tools to choose from, and each has its own strengths and weaknesses. However, taking the following criteria into account will help you choose a well-rounded solution that will strengthen your security posture:

Integration with cloud and DevOps pipelines

Any good AI security tool will integrate seamlessly with CI/CD pipelines to provide automated monitoring, advanced threat detection, and remediation throughout the software development lifecycle. After all, it’s critical to identify and address vulnerabilities early to cut down on integration issues and minimize the risk of misconfigurations that could expose sensitive data.

Wiz, the first CNAPP to offer AI security posture management (AI-SPM), is a great example of a tool that integrates with both cloud native environments and DevOps workflows. It enables full-stack visibility and automated misconfiguration detection in both AI services and infrastructure as code.

Regulatory readiness and compliance support

Your AI security platform of choice should help you meet regulatory requirements like GDPR and CCPA, as well as other industry-specific standards. This includes automating compliance checks, identifying sensitive data, and providing audit trails. 

For instance, Wiz supports compliance automation for NIST and other frameworks. It also provides tools that automatically detect and protect sensitive training data.

Comprehensive visibility and shadow AI detection

Your security team needs tools that automatically discover all AI assets—including models, services, and SDKs—across your cloud environments to prevent shadow AI (unauthorized or undocumented AI usage). In other words, you need an inventory of AI resources, or an AI bill of materials (AI-BOM), to reduce the risks that come with unmonitored AI deployments.

Misconfiguration and vulnerability management

Look for tools that enforce secure configuration baselines, ideally with built-in rules for AI services, to save your security team work. A good tool should also continuously scan for misconfigurations and prioritize remediation based on risk so your team can focus on resolving the most critical issues first. 

Attack path analysis and proactive risk mitigation

Being able to respond quickly to security incidents is essential, but your main goal should be to prevent as many potential incidents as you can. 

The most effective AI security solutions are also the most proactive. They identify and eliminate attack paths to AI models and data using contextual analysis across cloud workloads, identities, and network exposures.

Boost your AI security with Wiz

Most security teams don’t love the idea of adding several more solutions to their tool stack. If that’s true of your team, too, the ideal scenario would be to find a comprehensive AI security solution that ticks most, if not all, of the above boxes. 

For countless companies, Wiz’s AI-SPM is that solution.

The AI Security Dashboard offered as part of Wiz’s AI-SPM

Wiz offers full-stack visibility into your AI pipelines via an AI-BOM and enforces secure configuration baselines with built-in rules that detect misconfigurations in your AI services. Additionally, it helps you proactively discover and remove critical attack paths related to AI models and training data with accurate risk prioritization.
