Have raised concerns about scanning engines and automation while continuing to rely on layered protection strategies

Incident response is something that requires more development from Barracuda's side. Regarding room for improvement for Barracuda Forensics and Incident Response, for the product, developing or improving the scanning engine is important, but it's a bit tricky. I know that they are working on it heavily. The difference between Barracuda and Sophos is Sophos focused heavily on cybersecurity while Barracuda tried to increase their product portfolio. Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy. However, there is room for improvement. The product is great. The teams that are supporting are great. But there is always room for improvement. Even if you have a product that you would give a rating of 10 out of 10, there is always room for improvement. The day we stop improving is the day we die. Regarding the scanning engine, Barracuda Forensics and Incident Response has a very good feature where you can create automated flows for how to handle specific emails that are detected as incidents. This needs a bit of an improvement. That's the only component of Barracuda Forensics and Incident Response that I believe requires improvement.

Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness

The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.
