ACES moved #authorization for ACES Meet onto Cerbos and wrote up how they did it step by step. Dual writes, a shadow run against production traffic, then cutover. Useful if you're planning the same move off in-app permission checks. Thank you @nori_nori_8! #

Most "#Keycloak alternative" lists mix four products. An authentication gateway, an OAuth server, a full #IdP and a policy engine solve different problems. We wrote up which fits which requirement, and when swapping IdP fixes nothing: 🔗 bit.ly/4h5MBEf #IAM

If your #agent chain forwards the user's access token to the next hop, you're not delegating. You're #impersonating. We wrote up what a chain that holds together looks like, a checklist to test your own design against & which standards are ready now. 🔗🛡️bit.ly/4gyFYce

Spin up an #AIagent and it needs a model to think with and tools to act with. Which model can it call? Which #MCP servers can it even open? Are the tool-call arguments inside policy? How #agentgateway + Cerbos decide all three at the gateway: bit.ly/43qNy2E

You cannot rely on agents self regulating their own access permissions!
Agents follow #access, not instructions. If the policy lives inside the agent, the #agent will always talk itself past the gate. How #IAM and security teams should be thinking about this before the #EUAIAct deadline. bit.ly/3QgXcBL

Identity gets the AI agent into the building. Authorization protects the vault. @alexolivier 's #EIC2026 takeaways. Why counting agents isn't controlling them, where the decision lives, and the audit evidence the EU AI Act will ask for. bit.ly/4uz4O1i

Building a multi-tenant SaaS app for enterprises? Here is a handy guide on how to properly build roles and permissions that scale for each one of your customers.
Fixed roles break when enterprises sign up for your #SaaS. Role explosion follows. Deals stall. We just published a guide on implementing #multitenant #authorization that scales without role explosion. 🔗 Download the ebook: bit.ly/3KJFmVc

The message from #ISC2Congress 2025 is clear: policy as code is the only way forward Continuous compliance, AI governance, and risk quantification are no longer optional Security teams need policies that deploy and test like software Read more🔗bit.ly/43f6W2T @ISC2

Adopting externalized authorization is a big shift. We turned lessons from helping hundreds of teams, into a 10-chapter guide covering everything from planning to rollout to governance. 📘 Get the “How to Adopt Externalized Authorization” ebook: bit.ly/4lisId5

Thank you French ATC, you made a 2.5 hr journey 4 hours long. France kinda reminded me of those war torn countries noone flies over.

Dear @AmericanAir this is such a bad and dangerous seat design. I am surprised no kid stuck their headphone jack into the open power plug so far!

Non human identities need permission control too.
Securing #NonHumanIdentities is crucial. NHIs need access to data & resources, and without proper #authorization these workloads can become security risks. How to authorize NHIs 👉 bit.ly/4i6Y2JQ #Cerbos #AccessControl #Security
