Offers strong incident response features but requires more asset visibility and flexibility
Dragos' best features are that they are more focused towards Incident Response, so they have a dedicated playbook in their platform, making it easier for anyone investigating any incidents to investigate the alerts. One of the main features of Dragos is that they have a dedicated Incident Response team, so if clients need any help, they are there to help. Dragos does real-time monitoring as well, collecting mirror traffic from the span port of the switch, and as soon as it gets the traffic, it analyzes it in real time and shows what's going on in the networks, which relates to the real-time visibility feature for ICS networks.

Complements any firewall
The core processors are there and it's able to generate reports for that. It also complements any kind of firewall. For example, if an end user is using Palo Alto as a firewall, they'd need another layer of firewall like the S-Series that will protect internal servers. It's something that complements any firewall in the market.

Pros

"Dragos' best features are that they are more focused towards Incident Response, so they have a dedicated playbook in their platform, making it easier for anyone investigating any incidents to investigate the alerts."
"Dragos is more expensive than other vendors, probably about fifteen to twenty percent more, but it is generally worth the investment."
"Setup is straightforward with the same reliability and scalability as the firewall series."
 

Cons

"I think Dragos can offer more flexibility similar to Nozomi and more visibility into the assets, nodes, and links, which would make it more competitive in the future."
"Dragos could improve its asset visibility and discovery tools, as the competitor Claroty has better options in this area."
"Lack of tools to help educate end users"
