Did you know that it's super easy now to find "at risk" #EntraID Helpdesk Administrators that can reset creds of non-admin users who own service principals with privileged MS Graph perms? This allows a user like this to escalate their privs all the way to Global Administrator.

David owns an Entra ID Service Principal with higher privileges. Seems fine, things need owners, right? Except he’s also excluded from Conditional Access policies 😲 That combo = hidden privilege escalation risk. See it in action 👉 https://t.co/T72UyEqsTA

Today feels like a "62e90394-69f5-4237-9190-012177145e10" day. #IYKYK One of our customers told us that we found over 70 individuals in "62e90394-69f5-4237-9190-012177145e10". 🫠 Just another day helping our customers assess #EntraID with @ARGOS_Cloud .

Nautilus Steel hit a wall. More orders meant slower processes. Manual workarounds piled up. And scaling? Nearly impossible without rebuilding everything. Priority ERP changed the story. A system that absorbs growth, flexes with demand, and scales without expensive reinvestment.

And another day where @Github Copilot isn't working properly. Now at least it's responding to requests, but jobs aren't getting picked up by GitHub Actions. We've had some queued already for over 30 minutes with seemingly no runners available.

Is there an issue with @github Copilot again? Assigning issues to it doesn't trigger any Copilot session.

2,150 detections → 7 real actions. Most scanners stop at “failed control.” ARGOS shows the blast radius and tells you what actually matters. How? Watch a quick demo here:
