Cybersecurity / AI Prompt Shield

Govern every AI prompt. Protect your data before it leaves your business.

Pentaguard AI Prompt Shield is Magna5’s managed service for governing AI use, enforcing data-protection policies, and providing on-demand visibility into AI activity, so confidential and regulated data doesn’t leave your business through a prompt.

/ What is Prompt Shield?

Employees are already using AI to move faster, often in apps IT never approved, can’t see, and can’t control. Pentaguard AI Prompt Shield covers browser-based tools including ChatGPT, Microsoft Copilot, Claude, and Gemini, with optional coverage for locally installed AI applications used by employees across the business, including executives, finance teams, power users, developers, and other knowledge workers.

See what your teams are actually using, apply the policies you already have, and catch risky prompts before sensitive data leaves your network.

/ Prompt Shield at a glance.

  • Prompt Shield is a managed service, not self-serve software. Magna5 deploys, tunes, and manages it for you.
  • It applies configured policies to prompts sent to ChatGPT, Microsoft Copilot, Claude, and Gemini in the browser, with optional coverage for AI apps installed locally on developer and technical workstations.
  • It can alert on, block, or redact prompts that contain confidential, personal, proprietary, or regulated data, based on the policies you set.
  • It works on its own. You don’t need Pentaguard AI Workspace, a Microsoft Copilot deployment, or any other Magna5 AI platform to use it.

Designed for transparent AI governance. Prompt Shield is deployed with customer-defined policies, employee notice, and role-based access to reporting. Prompt-content access is limited to authorized personnel under the customer’s governance process and Magna5’s approved support procedures.

/ Secure AI use across every platform.

  • Find your shadow AI. See which AI tools employees are actually using across your environment, including tools that were never formally approved.
  • Get on-demand AI activity reporting. See which AI tools are in use across your environment and review reporting when your authorized IT, security, compliance, or legal teams need it. Prompt Shield applies configured policies to identify, alert on, block, or redact risky data before it reaches an AI service.
  • Stop data before it leaves. Set policies to alert, block, or redact prompts containing confidential, personal, proprietary, or regulated data.
  • Extend protection to desktop AI applications. Cover locally installed AI tools used by executives, finance teams, power users, developers, and other employees whose work relies on desktop AI applications.

/ You can't rely on employees to remember the AI rules.

AI governance can’t depend on employees remembering what they can and can’t type into a prompt. Prompt Shield gives IT, security, compliance, and legal teams practical controls to manage AI risk without blocking people from using AI to get work done.

Magna5 works with your team to define which data types and AI policies matter most to your business, configure enforcement actions, deploy through your endpoint-management tools, and tune policies over time. Prompt Shield gives you visibility, policy enforcement, and reporting, so AI use stops being a blind spot.

/ Managed AI security from Magna5.

Magna5 deploys, tunes, and improves Prompt Shield’s controls on an ongoing basis, as your organization’s AI use changes.

  1. Scope the environment. We identify employee groups, AI usage patterns, your endpoint-management tools, and what initial policies you need.
  2. Configure governance policies. We define sensitive data types, approved AI tools, and how the system should respond to a risky prompt.
  3. Deploy and validate coverage. We roll out browser protection and, where needed, desktop protection, through the endpoint-management platform you already run.
  4. Manage and optimize over time. We provide and review on-demand reporting with your authorized stakeholders, tune policies, adapt to platform changes, and keep the reporting current.

/ Frequently asked questions about Pentaguard AI Prompt Shield.

What is Pentaguard AI Prompt Shield?

Pentaguard AI Prompt Shield is Magna5’s managed AI security service for providing AI-use visibility, policy enforcement, and data protection for employee AI activity. It helps you discover AI use, apply data-protection policies, and keep sensitive information from reaching AI tools you haven’t vetted.

Which AI tools does Prompt Shield protect?

Prompt Shield governs browser-based AI tools, including ChatGPT, Microsoft Copilot, Claude, and Gemini. You can add coverage for locally installed AI applications used across the organization, from executive and finance teams to power users, developers, and other business functions.

Can Prompt Shield block sensitive information from reaching AI tools?

Yes. Based on the policies you set, Prompt Shield can detect sensitive information in a prompt and alert on it, block it, or redact it before it reaches an AI service.

Does Prompt Shield help identify shadow AI?

Yes. Prompt Shield shows you which AI tools employees are using across the organization, including tools that IT or security never formally approved.

Is Prompt Shield only available to Pentaguard AI customers?

No. Prompt Shield is a standalone offering. You can run it alongside Pentaguard AI Workspace, Microsoft Copilot, or any third-party AI platform your organization already uses.

Does Prompt Shield replace a secure AI workspace?
