What Straiker Defend AI is
Straiker Defend AI provides runtime security for coding, productivity, and custom-built AI agents. It inspects prompts, reasoning steps, and tool calls to detect and block prompt injection, data exfiltration, and agent manipulation; Straiker reports 98.1% detection accuracy at under 300 ms latency. Coverage includes text, code, images, audio, and file uploads across multiple languages. The service identifies malicious or vulnerable MCP servers and tool connections through Straiker’s MCP Threat Database. It traces activity across users, models, tool chains, and agent-to-agent calls for root-cause analysis, anomaly detection, and audit readiness. Deployment uses a single hook-based API, SDK, webhook, or AI sensor integration without thick clients, proxies, firewalls, or infrastructure changes. Dashboards, audit logs, and Slack, email, or webhook alerts support monitoring. Listed integrations include Amazon Bedrock AgentCore, Google Vertex AI, Microsoft AI Foundry, Microsoft Copilot Studio, Kong AI Gateway, and LiteLLM. API, self-hosted, and web platforms are listed, with hybrid deployment. The platform plan is $100,000 a year on a 12-month contract, with Units sized through Straiker.
