EVE AI Core
EVE AI Core
Lakera Guard and EVE CoreGuard both sit in front of AI systems, but they solve different problems. Lakera focuses on AI security — detecting prompt injection and content threats in real time. EVE CoreGuard focuses on deterministic compliance enforcement and signed audit evidence for regulated industries. Here is a fair, architecture-level comparison.
Lakera Guard is an AI security product. It is designed to detect adversarial threats against LLM applications in real time — most notably prompt injection and jailbreak attempts, along with content threats — by scanning model inputs and outputs as they flow through an application. It is built to help teams ship LLM features without exposing them to a growing class of prompt-level attacks, and it is a recognized, specialized product in the AI security category.
Lakera focuses deeply on the adversarial-input problem — detecting attempts to override system instructions, exfiltrate data, or jailbreak a model. This is a hard, fast-moving threat surface, and dedicated investment in attack-pattern coverage is a real advantage.
It operates in the request path to flag threats as they happen, which is the right model for security threat detection where you want to catch a malicious prompt before it does damage.
Lakera is delivered as a guardrail layer that teams can put in front of LLM applications, making it straightforward to add a security boundary to an existing AI feature.
The difference is one of category, not quality. Lakera is an AI security layer; EVE CoreGuard is a compliance enforcement and evidence layer. CoreGuard's architecture is built around three properties that a real-time threat detector does not aim to provide:
CoreGuard decides ALLOW / BLOCK / MODIFY against a policy before the model output is used, using deterministic rule evaluation. The same input always produces the same governance decision — a property regulated model-risk frameworks require.
Every decision can be emitted as an Ed25519-signed record that an auditor can re-verify offline, with no EVE service in the loop. This is a compliance evidence artifact, not a threat alert.
CoreGuard ships policy packs mapped to regulatory frameworks — ECOA / Reg B, SR 11-7, HIPAA, and the EU AI Act — so a decision can be traced to a named compliance rule.
Compared on the dimensions that distinguish a compliance enforcement engine from an AI security guardrail.
| Dimension | EVE CoreGuard | Lakera Guard |
|---|---|---|
| Primary purpose | Regulatory compliance enforcement & audit evidence | AI security — prompt injection & content threat detection |
| Enforcement model | Deterministic rule evaluation (same input → same decision) | Real-time threat detection / scanning |
| Timing | Pre-execution — policy decided before the model output is used | In-path input/output scanning |
| Cryptographic proof | Ed25519-signed, offline-replayable decision records | Not the product's focus (security threat detection) |
| Audit trail | Per-decision signed evidence mapped to named policy rules | Security event logging |
| Regulatory policy packs | ECOA / Reg B, SR 11-7, HIPAA, EU AI Act | Not a regulatory compliance product |
| Deployment | SaaS, VPC, or on-prem — no data leaves your tenant | Guardrail layer in front of LLM applications |
If your primary requirement is defending an LLM application against prompt injection, jailbreaks, and content threats — catching adversarial inputs and risky outputs in real time — Lakera Guard is a specialized, mature product built for exactly that problem. EVE CoreGuard is not a prompt-injection threat detector and does not aim to replace one. Many regulated teams run both: a dedicated AI security layer for adversarial threats, and a deterministic compliance engine for enforcement and signed audit evidence. Choose Lakera when AI security is the job to be done; choose CoreGuard when you need provable, regulation-mapped enforcement decisions on the record.
