Features and specs

What each product offers, as listed by its team.

PromptBrake 7 features
CloudLinux 5 features
  • AI Security Testing
    138 automated checks across 18 attack categories for prompt injection, data leaks, unsafe tool behavior, and other AI risks.
  • Supported Targets
    Test AI API endpoints and web chatbots, including applications powered by agents and LLMs.
  • CI Release Gates
    Apply configured security criteria in CI to flag or block releases based on test results.
  • Self-Hosted Execution
    Run tests inside your infrastructure. Prompts, credentials, responses, and test evidence stay in your environment.
  • Baseline Comparison
    Compare results against a baseline to identify regressions, fixes, and unresolved findings.
  • Free Security Resources
    Five public tools for release planning, security checklists, prompt injection examples, and OWASP test mapping.
  • Evidence and Reports
    Review findings with evidence and remediation guidance, and export JSON or PDF reports.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

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

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer

Questions & Answers

As answered by people managing PromptBrake and CloudLinux.

Which are the primary technologies used for building your product?

PromptBrake's answer

PromptBrake uses Python and Flask, with SQLAlchemy for database access and Flask-Migrate/Alembic for migrations. SQLite is the default database.

The interface uses server-rendered Jinja2 templates, JavaScript, and CSS. Gunicorn serves the application, and Docker packages the deployment. Playwright supports browser-based chatbot testing.

The hosted portal integrates Firebase Authentication for identity and Stripe for subscription billing. The self-hosted runner executes security tests inside customer-controlled infrastructure.

How would you describe the primary audience of your product?

PromptBrake's answer

Teams building and releasing AI products: agents, copilots, chatbots, RAG applications, and LLM-backed APIs.

Users include founders, AI product builders, engineering teams, security teams, and agencies delivering AI applications for clients. They need to test for prompt injection, data exposure, and unsafe behavior before launch and repeat those checks as their products change.

What's the story behind your product?

PromptBrake's answer

PromptBrake addresses a practical gap: an AI product can perform well in a demo yet still expose sensitive information or follow malicious instructions.

The goal is to make security testing a repeatable part of AI product releases. Teams can test their application, inspect evidence, fix failures, and rerun checks after changes.

That focus connects PromptBrake’s free planning resources with its self-hosted runner, findings, baseline comparisons, and CI release gates: helping teams make better-informed decisions before an AI release reaches customers.

What makes your product unique?

PromptBrake's answer

PromptBrake brings automated AI security testing, evidence-backed findings, remediation guidance, baseline comparison, and CI release gates into one workflow.

Run 138 checks across 18 attack categories against your AI application using a self-hosted runner inside your infrastructure. Review failures, fix them, and retest before release.

The focus is practical: help teams turn security findings into release decisions while keeping prompts, credentials, responses, and test evidence in their own environment.

Why should a person choose your product over its competitors?

PromptBrake's answer

Choose PromptBrake for repeatable AI security testing with a maintained test suite, actionable findings, and a self-hosted deployment model.

It helps teams test before launch and after changes to prompts, models, or workflows. Evidence and remediation guidance support fixes, baseline comparison highlights regressions, and CI gates help enforce release criteria.
