Featured Reviews

TarunKumar11 - PeerSpot reviewer
Global Leadership Council at a tech company with 10,001+ employees
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.
Tejas Jain - PeerSpot reviewer
Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
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.
