When to Choose Orca Security vs Tenable
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Orca's risk scoring weighs vulnerability severity against accessibility, lateral movement paths, and data sensitivity, reducing a noise pile of 10,000 CVEs to 50 actionable critical risks.
Tenable.io correlates vulnerability severity with asset criticality scores, surfacing the top 3% of vulnerabilities that pose real risk versus thousands of theoretical findings.
Orca SideScanning reads cloud workload runtime data out-of-band at the hypervisor level, detecting CVEs, malware, and misconfigurations without installing a single agent across thousands of instances.
Orca's compliance checks map findings to CIS Benchmarks, PCI DSS, and SOC 2 controls, generating a gap report for a new AWS environment within hours of connecting the first account.
Tenable Identity Exposure maps Active Directory misconfigurations to known attack paths like AS-REP Roasting, showing how attackers could escalate from a standard user to Domain Admin.
Tenable Attack Surface Management discovers internet-facing assets not in the asset inventory, attributing orphaned domains and IP ranges back to the owning organization.
