Problem
Ransomware attacks continue to be a primary cyber threat, resulting in significant financial losses, operational downtime, and reputational damage for businesses. Traditional security measures often fail to prevent sophisticated ransomware attacks, leading to data encryption, exfiltration, and double extortion attempts. Recovery from these attacks can take weeks and incur substantial incident response costs.
Solution
Halcyon provides a cyber resilience platform designed to neutralize ransomware threats in real time, preventing data exfiltration and minimizing downtime. The platform employs a multi-layered approach, utilizing AI/ML models to identify and block ransomware before execution. Halcyon intercepts encryption keys during an attack, enabling automated decryption and preventing the need to pay ransoms. Its Data Exfiltration Prevention (DXP) capabilities stop data from leaving the environment, mitigating the risk of double extortion.
Target Audience
The primary target audience includes enterprises and small to medium-sized businesses across various industries seeking to enhance their ransomware protection and cyber resilience, as well as MSSPs/MSPs looking for a turn-key ransomware service to offer their customers.
