EVE AI Core
EVE AI Core
Robust Intelligence pioneered the AI Firewall and algorithmic red-teaming. It was acquired by Cisco in 2024 and its technology now ships inside Cisco AI Defense — you can no longer buy "Robust Intelligence" as a standalone product. EVE CoreGuard is a deterministic governance engine: it enforces a regulatory policy and signs the decision, where Cisco AI Defense detects AI security threats.
Category: AI security — AI Validation + AI Firewall (acquired by Cisco).
Robust Intelligence was a pioneer of AI security — the "AI Firewall" for runtime input/output protection and AI Validation for pre-production red-teaming (including the published Tree-of-Attacks-with-Pruning method). It was acquired by Cisco in October 2024 (reported ~$400M; deal terms not officially confirmed). The standalone brand and product no longer exist; the technology is now foundational to Cisco AI Defense.
Cisco AI Defense detects AI security threats — prompt injection, jailbreak, data exfiltration, supply-chain and agentic risks — using a hybrid of deterministic pattern rules (YARA), proprietary ML, and frontier-LLM semantic analysis (via Amazon Bedrock). The runtime firewall can block; the detection engine is ML/LLM-based and therefore non-deterministic in the forensic sense.
EVE CoreGuard is not an AI security firewall. It is the deterministic governance enforcement plane: a zero-LLM, fail-closed verdict against a versioned regulatory pack, emitted as a signed certificate with offline replay and runtime attestation. Cisco AI Defense secures the AI attack surface; EVE CoreGuard proves regulatory compliance at each decision. They are complementary controls.
Pioneered the AI Firewall and algorithmic red-teaming (TAP); strong runtime threat protection and pre-production validation across the AI attack surface — a 2024 Gartner Cool Vendor for AI Security.
Now part of Cisco AI Defense and the Cisco Security Cloud, with Talos threat intelligence, network enforcement mesh, and enterprise deployment (SaaS control plane, VPC, on-prem AI PODs).
Scans models, MCP servers, dependencies, and agent skills; secures MCP and agent-to-agent traffic — breadth across AI security that a deterministic compliance gate does not target.
Compared on the dimensions that distinguish a deterministic governance enforcement plane from Robust Intelligence.
| Dimension | EVE CoreGuard | Robust Intelligence |
|---|---|---|
| Primary purpose | Deterministic pre-execution governance & enforcement (the enforcement plane) | AI security — runtime AI Firewall + pre-production AI Validation / red-teaming |
| Vendor status | Independent (EVE NeuroSystems LLC) | Acquired by Cisco (2024); sold only as part of Cisco AI Defense |
| Enforcement timing | Pre-execution gate — decides ALLOW / BLOCK / MODIFY before the action runs | Runtime firewall (can block) + pre-production validation/testing |
| Decision model | Deterministic rule evaluation — same input always yields the same verdict | Hybrid — YARA pattern rules + proprietary ML + frontier-LLM semantic analysis (non-deterministic) |
| Zero-LLM enforcement verdict | ✓ Zero-LLM enforcement verdict (Layer A) | — Uses ML and frontier LLMs for detection |
| Fail-closed default | ✓ Fail-closed by default | Partial — firewall blocks flagged traffic; infra-failure behavior not publicly documented |
| Cryptographic decision certificate | ✓ Ed25519-signed decision certificate per verdict | — Publicly documented capability not identified. |
| Offline / replay verification | ✓ Offline + replay verification | — Publicly documented capability not identified. |
| Runtime attestation | ✓ Runtime attestation (attestation-bound execution authority) | — Publicly documented capability not identified. |
| Signed audit lineage | ✓ Signed audit lineage (signed audit bus + Merkle roots) | Audit history for SOX/GDPR; DefenseClaw logs (SQLite/JSONL); cryptographic signing not publicly documented |
| Regulatory policy packs | ✓ Executable packs: ECOA/Reg B, FCRA, SR 11-7, HIPAA, EU AI Act, NIST AI RMF | References OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF; security frameworks, not executable enforcement packs |
| AI security & red-teaming | Out of scope | ✓ Core strength |
✓ = publicly documented · Partial = partial / configurable · — = "Publicly documented capability not identified."
Cisco AI Defense (built on Robust Intelligence) secures the AI attack surface — it detects and blocks adversarial and unsafe traffic using ML and LLM-based analysis. EVE CoreGuard governs the compliance decision — it deterministically enforces a regulatory policy and signs the verdict. Security detection and provable compliance enforcement are different controls; one defends against attackers, the other proves to a regulator that each decision followed policy and can be replayed.
Cisco AI Defense answers "is this traffic malicious or unsafe?" with ML/LLM detection. EVE CoreGuard answers "does this decision comply, and can I prove it?" with deterministic rules and a signed certificate.
AI Defense detection uses ML classifiers and frontier LLMs (Bedrock) — powerful but non-deterministic. EVE CoreGuard's enforcement verdict is deterministic and zero-LLM, so it can be replayed and signed.
Run Cisco AI Defense for AI security breadth and EVE CoreGuard as the deterministic compliance enforcement plane that produces examiner-ready, signed evidence. They are complementary layers.
Choose Cisco AI Defense (the home of Robust Intelligence's technology) when your primary need is AI security: runtime protection against prompt injection, jailbreaks, and data exfiltration; pre-production red-teaming; and supply-chain/agentic coverage at Cisco scale with Talos threat intelligence. If you are already a Cisco security customer, the integration is a real advantage.
Choose EVE CoreGuard when you need deterministic, provable compliance enforcement rather than AI threat detection: a fail-closed, zero-LLM verdict against a versioned regulatory pack (ECOA/Reg B, SR 11-7, HIPAA, EU AI Act), emitted as a signed certificate you can verify offline and replay for an examiner. It complements, rather than replaces, an AI security layer.
Book a review and we will walk your use case through EVE CoreGuard — including a signed decision record you can verify offline. Pilot from $37,500; Enforcement from $150,000/yr.
