Gen-AI Risks

Your AI attack surface is growing. Your security isn't.

AI applications, agentic workflows, and MCP connections create threats that traditional security tools can't detect, let alone stop.

Prompt injection

Attackers embed malicious instructions in user inputs or external content sources, manipulating AI systems to leak sensitive data, execute unauthorized commands, or bypass security controls entirely.

Jailbreak attacks

Adversaries manipulate AI to bypass safety guardrails and content policies, generating harmful, biased, or policy-violating content that creates compliance violations and reputational damage.

Data exfiltration

Attackers exploit context windows, RAG pipelines, and MCP integrations through seemingly legitimate queries, extracting PII, intellectual property, and confidential data that evades traditional DLP detection.

Excessive agent autonomy

Compromised AI agents gain unauthorized control over enterprise systems and workflows, executing unauthorized actions, poisoning decision-making, and triggering cascading failures across multi-agent systems.

Tool abuse & API exploitation

Attackers weaponize AI-integrated tools and APIs to perform unauthorized transactions, manipulate connected systems, and generate harmful content at scale: causing financial loss and brand damage.

Resource exhaustion

Attackers trigger infinite loops, abuse token limits, or launch recursive API attacks, draining compute resources, causing system unavailability, and incurring massive cost overruns.

The endpoint gap

AI agents can access secrets, run commands and send data outside your company without security seeing what caused it.

Claude Code, Cursor, Codex, Copilot and browser agents can read sensitive files, use credentials, run commands and send data outside your company.

How we secure AI systems?

3-Phase AI security framework

Repello follows a proprietary 3 phase framework to provide end to end security for AI systems: Discovery feeds continuous testing, testing results calibrate runtime defenses, and runtime insights improve future testing — creating an integrated security ecosystem.

End-to-end AI security architecture

Inventorize

  • Discover every AI system running in production
  • Build a living AI Bill of Materials (AI BOM)
  • Map AI applications, agentic workflows and exposure paths

AI Red Teaming

  • Autonomously red-team your AI applications
  • Test text, image and audio against 15M+ evolving attack patterns
  • Map findings to OWASP, NIST and MITRE standards

Adaptive guardrails

  • Turn red-team findings into runtime controls
  • Monitor multilingual, multimodal interactions in real time
  • Block threats and adapt as your AI systems change

The Repello platform

Traditional security can't protect AI. Repello does.

Three connected products provide continuous visibility, adversarial testing and runtime protection across your AI environment.

INVENTORY

Inventorize every AI system in production

Build a unified inventory of the agents, models, datasets, tools and connections operating across your production environment.
