Netskope

Netskope One CASB governs the use of cloud applications whether or not the organisation manages them, which is the part of the problem most tools handle badly.

Its defining choice is granularity. Rather than take a coarse grained approach by blocking services entirely, Netskope provides a deep understanding of cloud service usage and lets policies target user, application, instance, risk, activity, data and device. That distinction decides whether a security programme succeeds, because blanket blocking of a service employees need simply pushes the work onto personal accounts where nothing is visible at all.

Application risk scoring is AI driven through the Cloud Confidence Index, which extracts context from each new SaaS application whether or not it has been classified, correlating against more than 50 application attributes based on the Cloud Security Alliance Cloud Controls Matrix. The large language models answer queries in natural language and return tailored risk insights per application, which keeps pace with SaaS sprawl in a way manual review cannot.

Data loss prevention runs with contextual awareness of cloud content, covering email, chat, file sharing, web forums and screen captures, and supports file and binary fingerprinting, optical character recognition, exact data matching and machine learning image classification. Generative AI is treated as a first class surface, with inline inspection of public large language model interactions including Model Context Protocol calls. The CASB sits inside a wider platform spanning SSPM, SD-WAN, firewall as a service and advanced analytics. Pricing is not published.
