ProtectifyAI Aegis

ProtectifyAI Aegis is an End-to-End AI Agent Security Platform designed for enterprises building and deploying internal AI infrastructure. It provides a unified solution for the Discovery, Security, and Governance of autonomous AI agents, ensuring they meet strict regulatory standards like the EU AI Act and ISO 42001. ProtectifyAI Aegis is built for CISOs, AI Engineers, and Compliance Leaders who need to secure the "backend" of their AI adoption. While browser-based tools are often monitored, organizations face a critical blind spot in their infrastructure: engineering teams are spinning up "Shadow Agents" (local LLMs, Vector DBs, and APIs) that bypass standard firewalls. This creates new attack vectors—such as Indirect Prompt Injection and Excessive Agency—that traditional security tools cannot detect. The platform works via an intelligent "Omni-Scanner" that maps the entire AI agent lifecycle. It combines automated discovery with continuous "Red Teaming" to stress-test agents for vulnerabilities before they are deployed, bridging the gap between rapid AI innovation and enterprise compliance. Automated AI Asset Discovery: Instantly maps your entire AI infrastructure graph. It detects and catalogs hidden "Shadow Agents"—including local models (e.g., Ollama), vector databases (e.g., Pinecone), and unmonitored APIs—providing complete visibility into the backend AI attack surface. Continuous Security & Red Teaming: Goes beyond static scanning by launching automated, adversary-style attacks against your agents. It tests for the OWASP Top 10 for LLMs (including Prompt Injection, Jailbreaking, and Sycophancy) to validate that agents cannot be hijacked or tricked into revealing sensitive data. Regulatory Governance & Compliance: Automatically maps technical vulnerability findings to global frameworks, generating audit-ready reports for the EU AI Act, ISO 42001, and NIST AI RMF. This ensures that every deployed agent meets the necessary legal and safety standards. Real-Time Risk Guardrails: Monitors agent behavior for "Excessive Agency" risks, such as unauthorized "Write/Delete" permissions to sensitive internal databases, ensuring that autonomous agents remain within safe operational boundaries. Enable Secure Agent Development: Allows engineering teams to build, test, and ship proprietary AI agents faster. By automating the security testing pipeline, Aegis removes the bottleneck of manual reviews, enabling secure innovation at scale.

ProtectifyAI Guard

ProtectifyAI Guard is an AI Security Posture Management (AI-SPM) and Data Loss Prevention (DLP) platform designed for enterprises. It helps security, compliance, and legal teams manage the risks of generative AI by preventing sensitive data from being leaked into public AI tools. The solution provides real-time visibility and control over "Shadow AI"—the unmonitored use of applications like ChatGPT, Gemini, and others by employees. ProtectifyAI Guard is built for CISOs, Data Protection Officers (DPOs), and IT leaders in highly regulated industries such as legal, finance, and healthcare. These organizations face a critical blind spot: traditional security tools (like network firewalls and legacy DLP) are ineffective at monitoring or blocking sensitive data (like client PII, proprietary source code, or M&A details) that is copied and pasted directly into a browser. This creates a high risk of catastrophic data breaches, compliance violations (GDPR), and the inadvertent waiver of attorney-client privilege. The platform works by deploying a lightweight, ISO 27001-compliant browser extension that acts as a "CCTV" for all employee AI interactions. It inspects prompts in real-time before they leave the endpoint, providing a crucial layer of defense that policies and trust alone cannot. Real-Time Data Leak Prevention: Automatically detects and blocks sensitive data patterns (e.g., source code, PII, financial records) from being submitted to any GenAI tool, enforcing data policies at the point of action. Complete "Shadow AI" Visibility: Provides a unified dashboard that discovers and inventories all AI tools being used across the organization (sanctioned or unsanctioned), identifies high-risk users, and visualizes data exposure patterns. Actionable User Coaching: Moves beyond simple blocking by providing employees with real-time, contextual pop-up alerts. This coaches users on safe AI practices and reinforces security training without hindering productivity. Compliance & Audit Trail: Captures an immutable audit log of all AI interactions (prompts, responses, and policy actions), providing the technical proof needed to demonstrate compliance with regulations like GDPR. Enable Safe AI Adoption: Allows organizations to confidently embrace the productivity benefits of generative AI by managing the risk, rather than resorting to ineffective AI bans that employees often bypass.
