Ship AI features without shipping vulnerabilities. PromptBrake is a pre-release security testing platform for LLM-powered APIs โ€” point it at your endpoint and run repeatable scans for prompt injection, data leaks, unsafe tool use, and output bypasses, mapped to the OWASP LLM Top 10.

Each finding includes evidence logs and remediation guidance, so you know exactly what to fix. Compare runs to catch regressions, and plug the same checks into CI to gate risky releases.

Works with OpenAI, Claude, Gemini, and custom LLM-backed endpoints. Also includes free tools such as an LLM security checklist, a prompt injection payload generator, and an OWASP LLM test case mapper to help teams validate their setup early.

UTMStack stands out in threat prevention by merging SIEM and XDR technologies into a unified platform, surpassing the boundaries of traditional systems. Our unique approach allows correlating in real-time log data, threat intelligence, and malware activity patterns from multiple sources. This enables identifying and halting complex threats that use stealthy techniques. Your antivirus protects your workstation from malware, but how do you protect your business from Advanced Persistent Threats?

Advanced Persistent Threats (APTs) are a leading cybersecurity threat for businesses. They involve sneaky, ongoing hacking attempts that are highly sophisticated and capable of bypassing conventional security defenses to manifest as ransomware or data breaches.

To fight off APTs, businesses need a layered defense strategy. This includes using systems that manage security information and events (known as SIEM), keeping updated with threat intelligence, and ensuring compliance controls.

UTMStack provides these solutions by actively monitoring billions of threat intelligence data nodes and correlating them with your data in real time to achieve the ultimate threat detection and response in a user-friendly interface. Artificial Intelligence integrations can be used to supervise this process for improved accuracy and continuous learning optionally.

Analysis of PromptBrake

Overall verdict

  • I don't have verified information about PromptBrake (promptbrake.com), so I can't confirm whether it's a good product. Please verify its features, reviews, and reputation directly before making a decision.

Why this product is good

  • I have no reliable data on PromptBrake's actual features or performance, so any specific claims would be unverified
  • The name suggests it may be a prompt management or AI safety/moderation tool, but this is only speculation and should be confirmed
  • Independent user reviews and third-party evaluations, if available, would offer more trustworthy insight than assumptions
  • Checking the official website, documentation, pricing, and security/privacy policies is the best way to judge its quality

Recommended for

  • Users who first independently verify the tool's features and legitimacy
  • Teams evaluating AI prompt management or moderation tools who can run a trial or demo
  • Anyone who reads current user reviews and compares alternatives before committing

Questions & Answers

As answered by people managing PromptBrake and UTMStack.

What makes your product unique?

PromptBrake's answer

PromptBrake is the only LLM API security scanner built as a product, not a framework. While open-source tools like Promptfoo and Garak give you a flexible harness for building your own red-team workflow, PromptBrake gives you an opinionated 12-test suite (60+ real-world attack scenarios, OWASP LLM Top 10-aligned) that runs against your endpoint with zero configuration. Every finding comes with PASS/WARN/FAIL verdicts, evidence logs, and concrete remediation steps โ€” so engineers know exactly what broke and how to fix it. Compare any two runs to track regressions and fixes between releases, and drop the same scans into CI as a release gate. Works with OpenAI, Claude, Gemini, and custom LLM-backed endpoints. No security team, no harness setup, no agent install โ€” point it at your endpoint and ship with confidence.

UTMStack's answer:

UTMStack is a security solution that offers unique advantages compared to other options. It is built on open-source technologies, which means users can customize it to their specific needs. UTMStack also integrates easily with other security tools, creating a complete security ecosystem that leverages existing investments. The platform combines SIEM and XDR technologies, allowing for real-time correlation of data from multiple sources. This helps identify and stop complex threats that use stealthy techniques. UTMStack monitors billions of threat intelligence data nodes and correlates them with your data in real-time, providing effective threat detection and response in a user-friendly interface. It is also a cost-effective option, eliminating expensive licensing fees associated with commercial UTM products, allowing organizations to implement robust security measures without breaking the budget.

Why should a person choose your product over its competitors?

PromptBrake's answer

Choose PromptBrake when you want a security check, not a security project. Open-source tools like Promptfoo and Garak are powerful, but expect you to design your own test suite, write probes, and interpret raw output โ€” that's a week of setup before your first useful result. Manual AI pentests deliver depth but cost $5,000โ€“$20,000 per audit and run at best quarterly. PromptBrake fits the gap: an opinionated, repeatable suite you can run before every release, with results your engineers can act on without a security background. If your team ships AI features faster than a security calendar can keep up, that's the workflow PromptBrake is built for.

UTMStack's answer:

UTMStack is a great choice for businesses looking for a UTM solution for the following reasons:

  1. Flexibility: UTMStack is open-source, allowing for customization and modification to fit specific needs.

  2. Affordability: UTMStack does not require expensive licensing fees and provides ongoing updates.

  3. Community Support: UTMStack has an active open-source community that offers support and contributes to developments.

  4. Trust: UTMStack's transparency builds trust by allowing users to review the source code.

  5. Scalability and Customizability: UTMStack's modular architecture allows for scalability and customizability.

  6. Integration Capabilities: UTMStack can integrate seamlessly with other security tools and systems.

  7. Innovation: UTMStack stays up-to-date with the latest security technologies through continuous improvement.

How would you describe the primary audience of your product?

PromptBrake's answer

Engineering teams shipping LLM-powered APIs who are accountable for security but don't have a dedicated security team. That includes startup engineers wiring an AI feature into production, platform teams adding LLM endpoints to existing apps, and solo builders who need a credible security check before launch. The common thread: they own an AI endpoint, they're shipping fast, and they need a repeatable answer to "is this safe to release?" without hiring a pentester or building a red-team harness from scratch.

UTMStack's answer:

UTMStack is a solution that helps organizations and businesses manage cybersecurity and IT infrastructure. It caters to the needs of IT professionals, cybersecurity teams, and decision-makers responsible for digital security.

Frontend: server-rendered Jinja2 templates with vanilla JavaScript and CSS โ€” no SPA framework. Infrastructure: AWS (EC2), with Cloudflare in front for WAF and CDN.

What's the story behind your product?

PromptBrake's answer

If you've shipped an LLM-powered API, you've probably had this moment: someone asks, "Is it secure?" and you don't know where to start. OWASP publishes a Top 10 for LLMs. Headlines warn about prompt injection, jailbreaks, data leaks, and tool abuse. Blog posts disagree on what to test and how to test it. Open-source frameworks hand you a toolkit and assume you already know what to do with it. Manual pentests cost probably $5,000 to $20,000 and take weeks to schedule. Most engineers shipping AI features aren't security researchers โ€” they need a credible answer before the next release goes out. That's the gap PromptBrake was built for. One opinionated suite. Twelve tests covering what actually matters. PASS/WARN/FAIL results with evidence and remediation in plain language. Point it at your endpoint, see what's broken, fix it, ship. Security testing shouldn't require becoming a security expert first.
