It’s also interesting to note that Sookasa offers flexibility in terms of how users want to use the service. Companies who deal with sensitive data are encouraged to keep the storage provider and encryption providers separate to further bolster protection against unauthorized access and alleviate concern regarding privacy breach liability.Īpart from boosting privacy, the service also offers administrative capabilities such as setting polices and the ability to either grant or remove access to specific users. Sookasa’s service is priced at 10/month or $100/year per member, backed up with a 30-day free trial. The company is also set to offer a free version of the service which may include personal encryption though administrative dashboard or compliance feature will not be included in the package.Īt the moment, Sookasa is the first software firm to introduce such service and holds the patents for the technology. Sookasa integrates the service with Dropbox as both companies share an investor. During his PhD, he founded and served as the CEO of Sookasa, a cloud storage security startup, which was acquired by Barracuda Networks in 2016.How to Set Up Two-Factor Authentication.How to Record the Screen on Your Windows PC or Mac.How to Convert YouTube Videos to MP3 Files.How to Save Money on Your Cell Phone Bill.How to Free Up Space on Your iPhone or iPad.How to Block Robotexts and Spam Messages.However, Sookasa promises to bring the technology to other platforms in the near future. Asaf completed his PhD at Stanford, where his research focused on how to provide reliability and performance guarantees in cloud storage systems, and was adopted by several companies, including Facebook, Tibco, and Chartbeat. His team is focused on developing new technologies for combating email-borne social engineering attacks. Sentinel achieves false positive rates of less than one in a million emails, and precision of 89%, outperforming prior art by several orders of magnitude.Īsaf Cidon is the Vice President of Email Security at Barracuda Networks, where he co-leads the email security team. Sentinel utilizes the public APIs of cloud-based email systems both to automatically learn the historical communication patterns of each organization, and to quarantine emails in real-time. We discuss how Sentinel's design addresses these challenges. The main challenges in designing Sentinel is the need to categorize millions of emails in order to train its classifiers, and to properly train the classifiers when the occurrence of spear phishing emails is very rare. We present Sentinel, a security system that automatically detects and quarantines spear phishing attacks in real-time in a production environment using supervised learning, without requiring any manual analysis or configuration. Prior research to prevent spear phishing requires manual work from security analysts and from a high false positive rate. Existing email security solutions are not effective in detecting spear phishing, because these attacks typically do not contain overtly malicious attachments or links, and are highly personalized. Spear phishing emails take several forms: some ask the recipient to wire transfer money to the attacker’s account, others request W-2 forms, and some trick the recipient into following a link, which compromises their credentials or downloads malware to their device. In recent years, spear phishing and email-borne social engineering have become one of the most costly security threats, causing over $9 billion in reported losses.
