Straiker Secures Custom-Built and first-party Agents
Secure custom-built agents you’re building & deploying.
Discover your full agent attack surface, then continuously test and protect custom-built agents on AWS Bedrock AgentCore, Azure AI Foundry, Copilot Studio, and MCP servers.
Problem
Custom-built AI agents connect to systems of record, build with MCP servers and third-party connectors, and go to production with an attack surface that no one has fully mapped.
Solution
Straiker first maps every agent, MCP server, and connector in your environment, then continuously tests them for agentic AI threats before deployment and protects them at runtime.

What's at stake when custom-built agents are unsecured
When your team uses:
risk 01
Agents vulnerable to prompt injections
Attackers inject malicious instructions through documents, APIs, and agent-to-agent communication. Poisoned MCP servers and compromised tools compound the risk, turning trusted integrations into attack vectors.
Risk 02
Data exfiltration through tool chains
Agents with broad access and risky MCP connections can move laterally across your systems, leading to unauthorized access and data exposure. And because agents are ephemeral, they can be hard to trace after the damage is done.
Risk 03
Expensive compliance gaps auditors will find
Agentic deployments need to meet specific technical controls that require continuous risk assessment, audit trails, and policy enforcement, including tool call validation, prompt injection logging, and containment testing for multi-agent systems.
Security at every stage of the custom-built agent lifecycle
Govern: See every agent and every connection.
Discover AI maps your custom-built agents and the MCP servers, tools, and infrastructure they connect to, giving security teams full visibility into what's deployed, what it has access to, and where the risks are. Powered by Discover AI
Build: Find exploitable weaknesses.
Ascend AI delivers continuous adversarial testing with the industry's highest attack success rate, probing multi-turn conversations, tool call abuse, data exfiltration paths, and emerging evasion techniques across multiple attack categories. Every build, every prompt change, every config update gets tested. Powered by Ascend AI
Deploy + Run: Stop threats on both sides of the prompt.
Defend AI provides subsecond runtime detection that monitors both inputs and outputs, blocking prompt injection, data exfiltration, tool misuse, agent hijacking, and harmful content generation across your agents in production. Powered by an AI engine trained on millions of real-world agentic attacks, our defenses evolve as fast as the threats do. Powered by Defend AI
Questions Straiker helps you answer
Are my agents vulnerable to prompt injection and tool call abuse before they reach production?
What MCP servers and tool integrations are my agents connected to, and are any of them risky?
If an agent is hijacked, what's the blast radius across connected systems?
Can I prove to auditors that my agents are continuously tested and monitored?
Are my agents leaking sensitive data through tool chains or cross-connector pivots?
Do I have full visibility into agent permissions, tool usage, and data access patterns?
faq
What types of custom-built agents does Straiker support?
Straiker supports agents built on AWS Bedrock AgentCore, Azure AI Foundry, Azure Copilot Studio, MCP, LangChain, and custom orchestration frameworks. Integration requires a single line of code via API, SDK, webhook, or gateway.
How does Ascend AI test my agents differently than a manual pen test?
Manual pen tests are one-time snapshots. Ascend AI runs continuous, automated adversarial testing that adapts to your agent's behavior, probing multi-turn conversations, tool call chains, and data exfiltration paths across multiple attack categories and strategies. It tests with every build, prompt change, or config update.
What threats does Defend AI block at runtime?
Defend AI detects and blocks prompt injection, data exfiltration, tool misuse, agent hijacking, remote code execution, resource exhaustion, harmful content generation, and toxic outputs, on both inputs and outputs, with subsecond latency.
How does Straiker help with AI compliance (OWASP, NIST, EU AI Act)?
Straiker maps testing and monitoring results to OWASP Top 10 for LLMs and Agentic AI, NIST AI RMF, MITRE ATLAS, and EU AI Act requirements. Continuous assessment generates audit trails and compliance evidence across your full agent inventory.
Can Straiker protect multi-agent systems?
Yes. Straiker monitors agent-to-agent communication and tool delegation chains, detecting when a compromised agent attempts to manipulate or hijack other agents in the system.
How is this different from the guardrails built into my LLM provider?
LLM-level guardrails protect the model. Straiker protects the agent: its tool calls, MCP connections, data access, multi-turn reasoning, and the actions it takes in your environment. These are different attack
