Room For Improvement

Cisco Secure Email faces complex UI, integration issues, high costs, and lacks advanced features, affecting usability and scalability.
Microsoft Exchange Online Protection needs improved flexibility, security, user experience, intuitive interface, pricing, support, and integration with other platforms.
The solution should better analyze the actual content rather than only focusing on the email header or origin.
Chief Information Security Officer at Abcl
It would be beneficial to have the functionality of the Email Threat Defense integrated into the Email Security Gateway so customers don't have to buy two products for full email protection.
Systems Engineer at a non-tech company with 51-200 employees
It may take nearly an hour to get back to normal while configuring policies.

Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous.

From an end-user point of view, I am quite happy with Microsoft Exchange Online Protection (EOP) because my favorite feature is the ease with which I can identify if an email is a phishing email or spam email.
Business Process Manager/ Educational Technologist at a educational organization with 1,001-5,000 employees
 

Setup Cost

Microsoft Exchange Online Protection pricing is seen as generally high, but justified by security features and Microsoft's reputation.
Its cost is bundled with other Cisco products.

The pricing structure is good as it is user-based or email client-based, which is positive for clients.
Systems Engineer at a non-tech company with 51-200 employees
The licensing is a mess and needs sorting out.

Technical Associate Network Security at Valuepoint Systems
Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Business Process Manager/ Educational Technologist at a educational organization with 1,001-5,000 employees
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.
