Time to value

Requires Expertise

You can use Silmaril to protect your autonomous AI agents from runtime security threats like prompt injections and unauthorized tool executions. It inspects incoming context, user instructions, and planned actions before any command executes. When suspicious tool calls, data exfiltration attempts, or memory poisoning patterns appear, the system intercepts and blocks them immediately. It runs continuously within your environment, generating defenses based on discovered attack sequences. You can deploy it alongside local agents, gateways, or self-hosted cloud infrastructure without adding noticeable execution delay to your tasks.

What Silmaril does

Inspect incoming user prompts and retrieved contextIntercept unauthorized tool calls before executionDeploy firewall SDK wrappers across agent frameworksRun threat simulations against agent interfacesLog execution traces and security violation eventsRetrain defense classifiers using newly discovered exploitsAudit agent trajectory decisions against internal security policiesRuntime evaluation of agent tool calls and commands before executionProtection against indirect prompt injection and context poisoningAutonomous threat-hunting agents that discover application vulnerabilitiesContinuous retraining loop using simulated and captured attack tracesSelf-hosted deployment in private AWS, GCP, or Azure clouds with zero token egressLow-latency classification with approximately 15 millisecond p90 inferenceFail-open architecture to prevent downtime during infrastructure failures
