How they differ

CISO Tribune files Rival Security under Exposure prioritisation and CTEM, Vulnerability management, and AI SOC analysts, and files Zafran Security under Exposure prioritisation and CTEM, Vulnerability management, and External attack surface management. Both list Exposure prioritisation and CTEM as the primary category.

Rival Security sells Agent Harness, a platform for running security agents with the context of a customer's cloud, code and scanners. Agent Harness hands the work to specialist subagents. Rival engineers build custom agents for a customer's environment and stack at no additional cost, and customers can also build their own agents.

Zafran Security sells the Zafran Platform, which brings vulnerability findings together across existing tools into a unified view of exposure. It takes cloud and AppSec findings from Wiz, Palo Alto Networks, Upwind, AWS and Snyk, and on-prem findings from Tenable, Qualys and Rapid7. Zafran Security also sells RemOps, which uses generative AI to consolidate overlapping remediation tasks and route work to owners. Its Zero Day Agent matches new threats to a live software inventory, and its Exposure Graph weighs what is running, reachable, exploited in the wild and critical to the business. Zafran connects to the security stack a customer already runs, with no new agent to deploy.

What it sells: Rival Security

What Agent Harness does[2][3]
Every agent runs on Rival's Agent Harness. Agent Harness reads the context of a customer's cloud, code and scanners and hands the work to specialist subagents.

What it sells: Zafran Security

What Zafran Platform does[2]
The Zafran platform takes cloud and AppSec findings from Wiz, Palo Alto Networks, Upwind, AWS and Snyk, and on-prem findings from Tenable, Qualys and Rapid7. Zafran applies a customer's own risk context to reveal which vulnerabilities are exploitable in its environment. Zafran uses existing security controls to show how to reduce exploitability across the environment. Zafran auto-assigns fixes to the right owner in Jira, Slack and ServiceNow.
What RemOps does[1][2]
RemOps uses generative AI to consolidate overlapping remediation tasks and create a clear get-well plan. RemOps routes work to the right owners through existing ticketing platforms.
What Zero Day Agent does[6]
Zafran's Zero Day Agent matches a flaw to a customer's live software inventory, showing which assets run the vulnerable version, which are reachable from the internet, and which are blocked by a live control. Zafran autonomously identifies which assets new threats affect every day, using threat intelligence matched against SBOM data.
What Exposure Graph does[2][7]
Zafran's Exposure Graph weighs what's running and reachable, exploited in the wild, unprotected by controls, and critical to the business. Zafran's exposure graph unifies findings from continuous detection, cloud, AppSec and on-prem scanners, adds risk context, and maps each exposure.
