Access through Prisma and 802.1X

I had a concept and wanted some guidance to help me think through it.

What function does port security still play in an organisation that has adopted Prisma access with complete tunnelling, which is set up to perform device check, user verification, and AD domain membership check? I.e 802.1X?

Even so, does it matter?

Hello @Katakuri2025

thanks for the post.

From my point of view in modern network the concept of port security is obsolete regardless you have Prisma Access deployed or not. Port security has many limitations from management as well as scalability point of view. Regular 802.1X or MAB authentication would be better alternative unless there is some limitation from end point preventing you to use it, then port security would be last resort.

If you have already deployed Prisma Access with features you described, then with adoption of this concept even 802.1X could go away unless you are in strictly regulated business.

Kind Regards

Pavel
