The Identity Firewall for AI Agents.
Sphyr provides cryptographic, financial, and behavioral boundaries for autonomous agents. Deploy with confidence knowing your agents are bounded by iron-clad security policies.
Autonomous Boundary Control
AI agents operate in milliseconds. Manual security can't keep up. Sphyr enforces hard-coded limits on agent behavior, from wallet spend caps to rate limits.
Financial Limits
Network Guardrails
Identity at the Edge.
Verified cryptographic signatures for every agent instruction, globally distributed.
languageRequest Forensics
Every proxied request is logged with salted hashes, session grouping, and outcome classification for post-incident analysis.
Deep JWT & Entropy Scanning
Recursively scans JWT payloads and request bodies for encoded secrets. High-entropy strings are flagged before they leave your perimeter. Minimal latency overhead at the edge.
The "Seat Belt" Philosophy
"Security is not a final destination, but a persistent layer of friction designed to protect speed. We build the seatbelts for the AI revolution."
In a world of defense-in-depth, Sphyr operates as the final immutable layer. If the agent's logic fails, the firewall holds. Our architecture ensures that even a compromised LLM cannot exceed the hard boundaries defined in the Sphyr console.
Technical Specification
Optimized for human readability and LLM context window injection.
HMAC Signature Verification
Every request is cryptographically signed. Unsigned or tampered requests are rejected before DNS resolution.
header: x-sphyr-hmac-sig SSRF Protection
Hardened request sanitization for agent-initiated fetch requests, preventing internal network exposure and exfiltration.
scope: egress_restrict_v1 Deep JWT & Entropy Scanning
Recursively scans JWT payloads and request bodies for encoded secrets. High-entropy strings are flagged before they leave your perimeter.
