XAIGuard vs Prompt Security
Prompt Security covers both employee GenAI usage and homegrown applications, with a browser extension and gateway-style inspection. It is one of the closest comparisons to XAIGuard's runtime layer; the difference is what sits around it.
Where each product is strongest.
Where XAIGuard wins
Agent and MCP governance built in
Autonomous agents get scoped identity, allowed tool and domain lists, spend ceilings and automatic quarantine on drift.
Audit-grade evidence chain
Hash-linked, Ed25519-signed records with auditor access, rather than exportable logs and screenshots.
Continuous adversarial testing
Red-team campaigns run on a schedule against your deployments and report a pass-rate you can show a board.
Framework mapping shipped
Controls map to OWASP LLM Top 10, NIST AI RMF, MITRE ATLAS, ISO/IEC 42001, the EU AI Act and GDPR out of the box.
Where Prompt Security wins
Mature employee-usage visibility
A well-developed browser extension and reporting layer for who is using which GenAI tool and what they paste into it.
Broad application-side connectors
Established integrations for inspecting homegrown LLM applications, with sizeable coverage of common model providers.
Established market presence
Longer commercial track record in GenAI security with references across enterprise deployments.
Focused product, quicker decision
If your requirement is squarely 'stop staff leaking data into ChatGPT', a narrower product is a shorter evaluation.
No asterisks.
| Capability | XAIGuard | Prompt Security |
|---|---|---|
| Employee GenAI monitoring | Browser shield + PAC + log ingestion | Browser extension — mature |
| Application-side guardrails | API proxy with policy verdicts | Yes |
| AI data posture scoring | Discover, classify, score, watch | Partial |
| Agent & MCP governance | Yes — containment and ceilings | Emerging |
| Adversarial testing | Continuous, published pass-rate | Not a core capability |
| Signed evidence exports | Ed25519, Merkle-rooted | Log export and reporting |
XAIGuard and Prompt Security, asked plainly.
Are the runtime layers equivalent?
They are close in intent. Evaluate on your own prompts: false-positive rate on internal jargon matters more than a feature grid.
What does XAIGuard add beyond runtime?
Data posture scoring, agent and MCP governance, scheduled adversarial testing and a signed evidence chain — all under one policy model.
Is migration difficult?
No firewall change is required. A PAC file or browser shield rollout can run alongside an existing tool during evaluation.
Evaluate both against your own traffic.
