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.

Cloud data protection has improved and automation reduces manual security tasks
The best features that Zscaler Cloud Firewall offers are that it is AI powered and automated. The automation especially reduces manual tasks as we used to have lots of manual activities for such services. Reporting is very powerful regarding the features of Zscaler Cloud Firewall. Zscaler Cloud Firewall has positively impacted my organization by increasing ROI, especially by reducing costs.
