Nightfall AI Alternatives for Data Loss Prevention in 2024

Nightfall AI is cloud data loss prevention (DLP) platform that helps organizations protect sensitive data across cloud applications and endpoints. Using Nightfall AI, businesses can surface regulated and protected information such as PII, shielding the organization from risk of regulatory penalties and reputational harm. Companies choose Nightfall AI for DLP because its cloud-native platform simplifies and consolidates DLP for SaaS, email, and generative AI, including ChatGPT.

While Nightfall AI has many useful features for businesses looking to secure their data, it may not be the right solution for every organization. In this article, we review Nightfall AI’s capabilities and shortcoming and compare them against top competitors in the marketplace today so you can make an informed decision about the DLP solution you choose.


Limitations of Nightfall AI for DLP 

While Nightfall AI offers many powerful features for organizations in need of DLP capabilities, some competitors do outperform it in some areas. For example, Nightfall AI’s altering system can be complex to configure and its AI may produce too many false positives, which can result in real security policy violations being overlooked. However, it may be difficult to reduce false positives without compromising the product’s sensitivity.

Nightfall AI’s technology is also largely keyword-based and lacks natural language processing capabilities such as sentiment and toxicity detection, which are offered by some competitors. 

While the setup and integration process was easy, there is a learning curve when it comes to fine-tuning the system to reduce false positives without compromising the sensitivity needed for detecting genuine issues. The alert system, although robust, can be overwhelming if not configured correctly, leading to alert fatigue among team members.AWS Marketplace Review

Most concerningly for DLP customers, to perform a historical scan in Nightfall AI requires pausing monitoring, leaving data exposed during that period, and Nightfall AI lacks a comprehensive suite of capabilities beyond DLP unless integrated with other products.


“While Nightfall offers robust detection capabilities for various types of sensitive data, it may have limitations in detecting new or unique data patterns, especially if they fall outside its pre-defined parameters.”

Some detection services offered do not work as advertised or are very much still in a beta testing phase."

"Nightfall is primarily designed to protect specific types of data, such as financial transactions OR PHI/PII, and may not be suitable for other use cases. This means that you may need to use additional privacy tools or workarounds to protect other types of sensitive information."

Nightfall AI Alternative: Forcepoint DLP

Forcepoint DLP is an enterprise-grade data loss prevention solution that provides unified data protection across all channels under a single console. Forcepoint DLP includes advanced data discovery, classification, and fingerprinting functionality, OCR to detect data in images, and pre-defined policies for compliance requirements covering 370+ regulations in 83 countries.

While admins appreciate Forcepoint DLP’s strong data protection capabilities and ease of use and deployment, some reviewers note that Forcepoint DLP’s rule sets are inconsistently effective, particularly when dealing with unstructured data. Forcepoint DLP also lacks some of the more advanced machine learning capabilities of other DLP solutions.

Ultimately, Forcepoint DLP offers a more comprehensive data protection suite with pre-defined policies and risk-adaptive features, but may have some limitations in device control and customer support. Nightfall AI, on the other hand, is a specialized cloud security DLP solution known for its ease of use and strong customer support, but may lack the broader data governance capabilities of Forcepoint.

Nightfall AI Alternative: Netskope

Netskope offers both cloud-based and on-prem DLP through its zero-trust SSE, providing comprehensive data protection across multiple vectors, including cloud-based SaaS apps, network connections, email, and endpoints. As a CASB, Netskope is positioned to discover, monitor, and protect sensitive data as it moves between locations. However, this may create delays that cause frustrations and slow the pace of collaboration.

Another consideration is Netskope’s AI/ML capabilities. These are primarily based on keyword matching and OCR and lack advanced sentiment and toxicity analysis offered by some alternatives. Additionally, Netskope does not share surrounding context when an event is indicated, potentially making it harder for investigators to determine intent.

In summary, both Netskope DLP and Nightfall AI offer robust data loss prevention capabilities, but with some differences in their approach and focus. Netskope provides a more comprehensive security platform with risk-aware data protection, while Nightfall AI is a specialized cloud DLP solution.
