Tenable Scan on Palo Alto firewall / Panorama

L4 Transporter

Hi All,


Are Tenable vulnerability scans (see below) on Palo Alto firewalls / Panorama resource intensive for the PA devices? Does this cause high DP or MP issues?




Thanks in advance.

I will clarify with the customer exactly which scan they are planning on using.

 I have been dealing with Tenable and Forescout scans from our Infosec team and they have been rather brutal on a PA 3020, not so much in scanning the PA itself, but scanning through the PA to other networks (Trust to DMZ/VPN/etc.). The Tenable servers tend to generate thousands of connections per second (seeing 20k+ cps with 3-4 scanning servers) which hammers the DP CPU.
