User chats with AI models

Sharing sensitive company data incorporated in AI chat communication with LLM models can lead to data leaks, intellectual property loses, privacy violations or regulatory penalties.

Support for SW developers 

Relying on AI advice when developing applications can introduce hidden bugs, security flaws or outdated practices if its suggestions aren’t carefully verified.

Applications using public LLMs

Utilizing public LLMs by entire applications introduces vulnerabilities like prompt injection, data theft and jailbreak exploits, threatening security, privacy and control over proprietary data.

Operating AI agents

Running AI agents on routine tasks can cause unnoticed errors, automation bias, or security risks if oversight is weak.
