How can the NGFW provide visibility around SaaS applications?

The ability of a next-generation firewall (NGFW) to provide visibility around SaaS applications is significantly enhanced through filtering based on industry certifications. This approach allows the NGFW to assess which SaaS applications are compliant with relevant security standards, providing insights into those applications that are safer or have been vetted according to recognized criteria.

By leveraging industry certifications, the NGFW can categorize and monitor the use of various SaaS applications across an organization. This means that organizations can have a clearer view of not only which applications are in use but also the trustworthiness of these applications based on established benchmarks. This can help in ensuring compliance with regulatory requirements and in implementing appropriate security controls tailored to the type of data processed by each application.

In this context, the other options do not effectively contribute to visibility around SaaS applications in the same way. Blocking all SaaS applications by default would eliminate visibility rather than enhance it. Integration with SaaS vendors could improve functionality, but the benefit of visibility would depend on the specific capabilities of that integration. Sending all files to WildFire for analysis focuses more on threat detection rather than providing a comprehensive view of SaaS application usage and compliance. Thus, filtering based on industry certifications stands out as the most effective method for achieving visibility.
