IN PARTNERSHIP WITH
AGENT-TO-AGENT
When one agent hands work to another, the message never touches a network. Your firewall cannot see it. Your gateway cannot see it. Your model guardrails never get a look. It is not that they are worse at catching it, they are structurally incapable of seeing it at all. Delphi runs inside the agents, so we read the delegation itself. An attack split across five agents and nine hops, invisible to everything watching from outside, reads as one event to us.
94.5%
detection accuracy across 500 adversarial agent-to-agent scenarios, and we published the benchmark, the first runtime A2A benchmark put in the open.
THE FLEET LAYER
A single sensor sees one agent. Fleet Intelligence sees all of them at once. Every xAIDR sensor streams its telemetry to one place, where it becomes a live map of your entire agent fleet: who is running, who is talking to whom, which tools are in play, and where trust is degrading. Correlation across agents catches attack chains that no single sensor could see, a probe on one agent and an exfiltration attempt on another, recognised as one coordinated event. This is the difference between watching agents one at a time and governing them as a fleet.
One live view of every registered agent, its connections, and its trust score
Cross-agent correlation that catches attack chains spanning multiple agents
Fleet-wide trust scoring, with automatic quarantine when standing collapses
Shadow agent discovery, surfacing agents nobody registered
Every signal exportable to your SIEM
Every agent and every principal measured against its own history. Applications behave like metronomes, people are diurnal, scheduled jobs are calendars. Departure from an established pattern is a signal before anything matches a known attack.
WHY DELPHI
The sensor runs inside each agent process. Threats are caught before the LLM call is made, not after the response arrives.
One URL change or one npm install. No new servers, no firewall rules, no changes to your existing LLM provider.
Sentinel Brain correlates behavior across every agent simultaneously. A coordinated attack across three agents becomes one alert, not three separate noise events.
Every agent carries an Ed25519 cryptographic identity via Microsoft AGT integration. Unregistered agents cannot impersonate trusted ones.
Every detection event maps to specific controls across 8 frameworks. OWASP, NIST, EU AI Act, ISO 42001. Evidence generated from runtime. No manual questionnaires.
Define tool whitelists, access scopes, and behavioral guardrails per agent. Policies enforced locally by each sensor. Custom content policies block hate speech, violence, and regulated advice categories.
Delphi consumes identity rather than issuing it. Point the gateway at your existing provider and every token is validated offline against its published keys. No callback into your identity plane, no new dependency in the authentication path, no directory to synchronise.
Delphi runs entirely inside your perimeter. Self-hosted, air-gapped if you need it, with no backend and no callout in the scan path. Telemetry carries a hash and a length, not your content. Your data, and your sovereignty over it, stay yours.
THE DIFFERENCE
Traditional tools watch for known patterns. Delphi understands intent, correlates behavior across agents, and responds autonomously. Runtime security built for systems that operate without humans in the loop.
Single-agent, input-only scanning
Static rules and policy configs
No visibility into agent-to-agent traffic
Compliance reports built manually
Cannot say which person an agent acted for
Revocation waits for the token to expire
Fleet-level inline scanning across all agents
Intent decomposition and behavioral correlation
Full A2A message inspection and trust scoring
Runtime evidence mapped to 8 frameworks
Verified principal and full delegation chain on every call
Denied on the next request, across every agent
