While interesting, the remote access client is where it's really valuable. It's ultimately a matter of priorities, I guess. Other vendors have had SAML support in their clients for years.
To me, being unable to support U2F as an MFA token is a big miss for a company that prides itself on being on the leading edge of security.
It pains me to say it, but Check Point has really paid little attention to remote access security for the past 4-5 years. Even the Mobile Access SSL-VPN is very long in the tooth. Hotfix after hotfix just to be able to use it on modern systems and browsers. And not even included in the JHF, but as special MABDA hotfixes that required a reboot of a firewall to install. Finally showing up in R80.40.
It's just my personal opinion, but it feels like Check Point is just chasing butterflies and not paying enough attention to the fundamentals.
