We run Harmony Endpoint on Infinity Portal and Quantum appliances managed with an on-premises SMS.
The Quantum cluster provides MAB SNX for remote users. (R81.20 T53).
Since last Friday, the phishing protection blade on HEP gradually started to block the MAB URL on some users and today it happened for everyone.
The question is why it happens and how can we prevent this other than going through TAC. We might have other organisations running HEP accessing such resources and creating exceptions in all tenants is impractical.
