Tackle your AI security challenges
As AI innovation speeds up, organizations are confronting big, new security challenges.
Agents create a new insider risk
By 2028, 25% of enterprise breaches will be linked to AI agent abuse, from external attackers and malicious insiders.1
Agents on devices risk using employee permissions
68% of organizations can't clearly distinguish AI agent activity from human activity.2
Overprivileged agents open new attack paths
According to Gartner®, “Through 2029, over 50% of successful cybersecurity attacks against AI agents will exploit access control issues, using direct or indirect prompt injection as an attack vector.” 3
Agents can expose data faster than you can react
32% of organizations' data security incidents involve generative AI tools.4
CAPABILITIES
Scale AI apps and agents securely with protection that adapts as risks change
- Find heterogenous AI apps, agents, and tools across the organization.
- Extend purpose-built identities to authenticate, authorize, govern, and protect AI agents.
- Combine identity, endpoint, network, and data signals into a dynamic risk level for each agent.
- Give each agent its own identity, separate from the user and the device, with only the data, tools, and actions the task requires.
- Apply Zero Trust to agents with task-based permissions that expand, restrict, or expire permissions based on agent intent or risk posture.
- Review and remove access across users and agents as purpose, ownership, or status changes and apply compliance controls.
- Enforce data policy across prompts, responses, and tool calls and adapt policies as agent risk dynamically increases.
- Trace runtime issues back to code, restrict which MCP servers and tools AI apps and agents can reach, and contain risky agents on the device.
- Stop threats and unintended behavior across AI apps and agents and drive remediation into developer workflows for fixes.
- Allow, constrain, require approval, block, or isolate based on changing risk.
- When a risk pattern appears on one agent, find every agent exposed to it and extend protection across your environments.
- Ensure access has been reduced, risks have been addressed, and no residual exposure remains.
