Specific to your question
We are upgrading the OpenSSL libraries that SBR uses to a modern release. This will add support for SHA2 based certs which includes newer cipher suites that Microsoft no requires. So, in theory, Windows 10 will be support as well as fixing the issues that were encountered with Microsoft released patches back in the spring to address several vulnerabilities.
I would contact your Pulse Secure sales team to see the roadmap of future features being added to SBR in the coming releases.
Thanks
