Why do you need to secure your AI?

Attack surfaces are ballooning, posing an increased risk for enterprises that consume or build AI apps.
Nightfall for SaaS

Human error

AI models are often deployed in environments where employees and customers alike can accidentally “over-share” sensitive data, such as via chatbots and virtual assistants.

Data exposure

AI models are trained on large datasets, and are often exposed to sensitive company and customer data as a result—leading to privacy breaches, noncompliance, and loss of customer trust.

Malicious threats

Threat actors can target AI models via data poisoning, jailbreaking, prompt injection, and other attacks in order to access sensitive company and customer data.

HIPAA reporting and monitoring made easy

Healthcare organizations need to protect PHI and comply with HIPAA. Nightfall automatically classifies all cloud data and finds at-risk patient data from a single platform.

  • Use prebuilt, high accuracy detectors or create your own

  • Build detection rules for your use cases

    Scan text and files, including images

  • Remediate sensitive data with redaction techniqu

Discover sensitive data across every facet of your Teams workspace

Filter content before API requests are sent to AI models

  • Create a detection rule with the Nightfall API or SDK client.

  • Send your outgoing prompt text in a request payload to the Nightfall API text scan endpoint. The Nightfall API will respond with any detected sensitive findings as well as the redacted payload.

  • Send the redacted prompt to the AI model using its API.

  • Maximize productivity, without compromising on AI tool effectiveness, as AI models don't need sensitive data in order to generate a cogent response.

Early access

Protect against adversarial attacks and create conversational guardrails

Keep AI apps secure and relevant.

  • Detect and prevent adversarial attacks including prompt injection, jailbreaking, data poisoning, gibberish, invisible and block text, and malicious URLs.

  • Add guardrails for conversation content, topics, code, languages, URLs, and more.

  • Identify dysfunctional conversations by checking LLM response refusal, user input sentiment, token limits, reading length, poorly constructed JSON, and more.

  • Maximize productivity, without compromising on AI tool effectiveness, as AI models don't need sensitive data in order to generate a cogent response.
