Secure internet access has reduced threats and simplifies firewall management for distributed teams
Threat detection needs improvement; Arista Edge Threat Management NG Firewall should follow Alto and Fortinet. One limitation that I've seen is AI-driven automation which needs to vastly improve. It has fewer third-party integrations, and therefore the adoption amongst very large enterprises is less; it's largely with the SMBs. Customer support can be improved. It's a smaller global footprint that Arista provides, with fewer certified partners in some regions and limited 24/7 support for premium vendors. I've categorically mentioned that it has sophisticated threat detection capabilities but they can be bettered. AI-driven automation can be improved, and therefore, I think the adoption with large enterprises can be much better. I think the current AI capabilities of Arista Edge Threat Management NG Firewall are a bit limited compared to other vendors. It primarily relies on threat intelligence feeds, signature-based detection, and reputation services. Currently, I would rate its AI capabilities as probably a seven out of ten because it does not provide for extensive GenAI or advanced ML-driven autonomous capabilities like some of its competitors. Threat intelligence aspects can be further improved, and I think there's a lot that the product can do with respect to the usage of AI. AI-driven automation and threat detection can vastly improve. I don't think they were purchased through AWS Marketplace. The adoption has to increase amongst large customers, and threat intelligence needs to improve for many customers to adopt, enhancing the security ecosystem that is relatively small.

Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. 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. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."
"Phish Blocker is a valuable feature."
"I would say that if you're a small and medium enterprise or an education institution and you have a distributed organization looking for a cost-effective and easy-to-manage next-generation firewall solution with fairly good security, VPN, filtering, and centralized management, then Arista Edge Threat Management NG Firewall is an excellent choice."
"The product's initial setup phase is easy."
"The IPS system is the best in the field."
"Mainly, it is very easy to understand, and the logs are very good."
"The most valuable feature of Palo Alto Networks K2-Series is the configuration, it is very clear."
"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."
"The application ID on the Palo Alto Networks K2-Series is able to understand the application traffic, and WildFire is also good."
"It is a stable solution."
"Technical support is very good."
"My advice to someone considering this solution would be that it's okay to spend a bit higher on your security products because Palo Alto is a bit more expensive than other products, but it is definitely worth it."
 

Cons

"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."
"Threat detection needs improvement; Arista Edge Threat Management NG Firewall should follow Alto and Fortinet."
"The documentation is not clear."
"The product has a lot to improve in the area of policy implementation."
"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced."
"Threat prevention could use improvement."
"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."
"The product should get frequent updates allowing us to add new signatures."
"Palo Alto doesn't have that extended visibility to the end point in their firewalls."
"If we have issues, they take anywhere from two days to a week to respond. I even wrote to their CEO because there was no response. When it comes to support, this is the worst company."
"The solution needs to constantly be adapting and updating."
"Palo Alto releases a lot of bug fixes for their firewalls, which means it's necessary to do frequent upgrades. They should work on decreasing their bugs so that upgrades aren't needed so often."
 

Pricing and Cost Advice

"I consider it an averagely-priced tool."
"The tool is quite cheap."
"We are on an annual license to use Palo Alto Networks K2-Series."
