Super excited! Just launched the #EntraID capability to quickly and easily create a security assessment, including diagrams of how resources relate, detailed reporting, and very soon also Entra ID attack paths. Free testing is available on our website.

Installed the new #VisualStudio 2026 and wow, it's snappy! Compared to VS2022 it loaded our #ARGOSCloudSecurity solution probably 3 times faster.

Since 2000, hospital prices have soared by over 250% – 3x the rate of inflation. Why? Mergers and consolidation give them more power to set prices. It’s time to hold hospitals accountable for rising health care costs. Learn more.

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.

Another annoying @github Copilot error. The agent is being told to "go away" (http 429).

Actually, it probably already is. Let Analyst1 handle it. From detection to disruption, we’ve got your back.

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 #entraid #m365

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:
