Featured Reviews

Kalpesh Potghante - PeerSpot reviewer
Senior Manager at Deloitte
Secure file sharing has protected global storage and improves confidence with external partners
The best features Antivirus for Amazon S3 offers include that it is really a built-in feature which is really great, as you don't have to do anything extra, there's no operational complexity or cost overhead associated with it, and because it's a managed solution, it's easy for us to configure policies as S3 buckets are created globally and make sure they have the necessary virus protection as needed. The simplicity and ease of policy configuration have helped my team day-to-day because, as it is part of the AWS ecosystem, I don't need to really hire a separate skill set to configure this service, and moreover, if I use the console, all the features are available to me at a click, and I can also programmatically control it, making configuring the antivirus part of setting S3 objects rather than setting up a separate service altogether on top of S3.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.
