The best way to protect against REvil/Sodinokibi ransomware is to take a multi-pronged approach involving security awareness, email scanning and audits of your current cybersecurity measures.
Security awareness involves training your staff to recognize potential phishing scams and faulty email attachments. This should always be the first line of defense for companies, as phishing and email scams are the most common attack vectors for ransomware criminals, including families such as Sodinokibi.
Cybersecurity experts like Mimecast offer security awareness training, email scanning, and cloud-based recovery archives so that even if you do suffer from a ransomware attack, you don’t have to feel beholden to cybercriminals to obtain access to private information.
