✓ Our Verdict

Solid choice for most workflows

Use Case

You need to prevent your autonomous agents from leaking PII, PHI, secrets, or credentials in outputs before storing or sending them to external services.

SolutionIntegrate Nightfall's REST API to scan agent-generated text, files, or data streams in real-time, automatically detecting and blocking/redacting sensitive info with 95% accuracy.

SetupSign up for free plan (3 GB/month), get API key in minutes, add a single API call to your agent's output pipeline.

Near-instant scans with low false positives thanks to AI detectors; scales well for agent workloads but watch free tier limits for high-volume agents.

accuracy

Use Case

You want agents to safely interact with GenAI tools like ChatGPT without accidentally exposing sensitive data via prompts or uploads.

SolutionEmbed Nightfall API scans in agent pipelines to inspect prompts/files before forwarding to Shadow AI, blocking leaks proactively.

SetupAPI integration as above; for full coverage, optional browser/endpoint agents if agents run in user sessions.

Excellent at catching transformed or contextual leaks legacy regex misses; minimal latency added to agent flows.[1][2]

Use Case

You're building agents that process unstructured cloud data and need to classify/remediate sensitive info at rest or in transit.

SolutionUse Nightfall's developer APIs to scan agent-managed data in SaaS/cloud sources, enabling custom DLP policies as code.

SetupAPI key + define detectors via UI or code; supports streaming scans for dynamic agent data.

High efficacy on PII/PHI/secrets with self-learning improvements; best for devs wanting tailored control over agent data hygiene.[4]

Limitation — minor

Free Tier Volume Cap

Limited to 3 GB/month scanned data; enterprise plans needed for production-scale agent fleets with heavy scanning.

Caution

Volume-Based Billing

Exceeding scan limits incurs enterprise costs; monitor agent output volume and implement client-side filtering to avoid surprises.
