Cato SASE Cloud Becomes First SASE Platform with Network-based Ransomware Protection

"Ransomware protection has become job one for every CISO and CIO, but too often enterprise defense strategies remain vulnerable whether by threat actors bypassing endpoint defenses or by manipulating insiders to spread ransomware," says Etay Maor, senior director of security strategy at Cato Networks. "By identifying ransomware by its underlying network characteristics, security teams can protect the enterprise regardless of the threat vector." "Ransomware protection has become job one for...

"Ransomware protection has become job one for every CISO and CIO, but too often enterprise defense strategies remain vulnerable whether by threat actors bypassing endpoint defenses or by manipulating insiders to spread ransomware," says Etay Maor, senior director of security strategy at Cato Networks. "By identifying ransomware by its underlying network characteristics, security teams can protect the enterprise regardless of the threat vector."

Extending Ransomware Protection from the Endpoint to the Network

With today's announcement, Cato's heuristic algorithms inspect all SMB (Server Message Block) protocol flows for ransomware. SMB is the protocol used by Windows to share files and folders.

Cato researchers trained and tested these algorithms against Cato's massive data warehouse, a data lake of end-to-end attributes for all traffic flows processed by the Cato SASE Cloud. Being the network, Cato has visibility into data normally blocked by firewalls and NATs. More than a trillion flows from all Cato-connected edges – sites, users, IoT devices, cloud-connected resources, and the Internet resources – populate Cato's data lake.

Once trained, the machine-learning heuristic algorithms inspect live SMB traffic flows for a combination of network attributes including:

When ransomware is identified, Cato automatically blocks SMB traffic from the source device, preventing lateral movement or file encryption, and notifies the customer.

Cato Delivers a Multilayered Ransomware Mitigation Strategy

Today's announcement is just part of Cato's broader, multilayered malware mitigation strategy of disrupting attacks across the MITRE ATT&CK framework.  As part of this strategy, Cato security researchers follow the techniques used by ransomware groups, updating Cato's defenses, and protecting enterprises against exploitation of known vulnerabilities in record time.
