Cisco Stealthwatch Cloud is a cloud-delivered and SaaS-based solution that provides visibility and threat detection across the AWS network. It does not require any software agents to be installed on the AWS instances, and it relies on AWS VPC flow logs to collect network traffic metadata. Cisco Stealthwatch Cloud analyzes the flow logs using machine learning and behavioral modeling to detect anomalies and threats, such as data exfiltration, lateral movement, reconnaissance, and compromised instances. Cisco Stealthwatch Cloud also provides contextual information and actionable alerts to help users respond to incidents and remediate issues.

Cisco Umbrella is a cloud-delivered and SaaS-based solution that provides DNS-layer security and web filtering for internet traffic. It does not provide visibility and threat detection for internal AWS network traffic, and it requires software agents to be installed on the endpoints or network devices to enforce policies and redirect DNS requests.

NetFlow collectors are devices or software applications that collect and analyze NetFlow records, which are generated by network devices to capture information about IP traffic flows. NetFlow collectors can provide visibility and threat detection for network traffic, but they are not cloud-delivered or SaaS-based solutions. They also require NetFlow exporters to be configured on the network devices, which may not be supported by AWS.

Cisco Cloudlock is a cloud-delivered and SaaS-based solution that provides cloud security posture management (CSPM) and cloud access security broker (CASB) capabilities for cloud applications and environments. It does not provide visibility and threat detection for AWS network traffic, and it does not rely on AWS VPC flow logs. It focuses on protecting cloud data, users, and configurations from misconfigurations, compliance violations, and malicious activities.Reference:=
