I would rate tech support from Palo Alto Networks at around eight out of ten points because we had dedicated people assigned to us.
We get Gold support from them, and they are pretty good.
I would rate the technical support for the Palo Alto Networks K2-Series from Palo Alto as nine out of ten points.
It is very effective because it prevents any indecent behaviors in the network or from outside the network.
I rate the technical support provided by SonicWall a perfect ten out of ten.
Vertical scaling allows you to purchase more powerful devices with additional RAM, compute, and larger model form factors.
The scalability rating is nine out of 10.
SonicWall NSSP offers features such as stateful firewall, deep packet inspections, IPS, application intelligence, user-based policies, centralized visibility from the management console, advanced protection with RFDPI, high-speed scanning, RTDMI technology, Capture ATP, cloud sandboxing, and encrypted traffic inspection with DPI-SSL and TLS.
Palo Alto typically doesn't have many glitches.
In 30 years, only three to four boxes out of 1,000 to 2,000 boxes have had issues.
The stability rating is 10 out of 10.
I think deep packet inspection of SonicWall NSSP is essential, as I require all features, including deep packet inspection, which I can enable and suggest to clients.
Enhancing web traffic protection would be a great upgrade.
L1 engineers cannot work on the Palo Alto Networks K2-Series because it's too complex, which requires L2 and above level of engineers.
With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models.
This would help end-user customers understand the impact when those firmwares are pushed into the live environment.
The issues I have experienced are not hardware-related but firmware-related, as Gen 7 has new hardware, while the firmware contains some issues that could be resolved but may take considerable time.
It's a little bit expensive.
The pricing for the Palo Alto Networks K2-Series solution is affordable.
When purchasing through local distributors such as ScanSource or Tech Data, they incur around 100% in taxes just for import procedures.
Overall, the K2-Series helps in much more protection, and dashboard compliances are being met.
We had configured dynamic user groups and App-ID based policies, which makes it all Zero Trust.
Mainly, it is very easy to understand, and the logs are very good.
SonicWall uses this information in real-time to enhance security functions such as firewall, DPI-SSL, ATP, and IPS to block threats at the network edge before they reach users.
Every time I have had a concern, they have resolved it in a single call.
