The most valuable features are Barracuda's policies for filtering various websites according to the organization's policies and blocking traffic for any P2P application like torrents. We discourage torrents, though a lot of people want to use them. The torrent application doesn't require any admin privileges. You can run it on your system. Barracuda is good at blocking torrent activity.
Apart from that, considering other tier-one applications, like Next-Generation Firewall, they also have web security in-built within their appliances or applications. Barracuda is still lagging behind in features like that, so they need to update if they want to be in the top spot.
Other features I'd like to see in Barracuda Features are ease-of-use for remote users. If you are a roaming user using an organization laptop, the organization has the right to apply the policy. When you are on-premises, you are opening the policy, not out-of-premises. The application that Barracuda Web Security Gateway provides is pretty clumsy and not very easy to work with, and they need to develop that. Either they provide a test platform that redirects the traffic or vice versa.
Moreover, the database is pretty average. Barracuda needs to enhance the database to stop unsolicited traffic. Reporting also needs to be quicker than it is. Barracuda doesn't give you any flexibility to provide reports to higher management. Organizations like us need to do a lot of reporting. When we submit our quarterly report, other appliances allow us to customize or get the reports in a way Barracuda can't because it is rigid with its reporting. Barracuda needs to give users the flexibility to create their reports. The reports offered by the solution are just fine. Finally, acceleration. Right at this moment, most websites are dynamic. For example, organizational websites get updated once a month. If Barracuda can help reduce bandwidth usage and accelerate browsing performance by analyzing these sorts of sites and doing their catching technology work accordingly.
Barracuda should also include DNSSEC, which offers strong protection for web security and is offered by competitors. Barracuda should also up their game for scanning and sandboxing. Likewise, their signatures need augmented intelligence or machine learning because you won't always be able to appraise things, and sometimes you have to go beyond that. You need to block it through its behavior.
