How Can OPSWAT Help
The FIRESTARTER backdoor’s ability to evade multiple security scans on a Cisco Firepower appliance is a powerful argument for defense-in-depth file inspection. MetaDefender’s multi-engine scanning with 30+ antivirus engines would provide a second opinion beyond the device’s native detection. The firmware-level persistence mechanism also highlights the value of OPSWAT’s MetaDefender CDR for firmware images and TrustNo.one for device posture assessment.
