Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"It can retract unsafe emails and remove them from the entire communication channel."
"The customizable rules allow you to change aspects."
"Prevention of account takeover by ransomware attackers has solved long-term problems that had become normal in the company."
"Spam protection is the most valuable feature."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"Avanan Cloud Email Security has empowered teams with modern data security management knowledge and provided enough awareness that helps employees to prepare for any outcomes."
"Now, we aren't worried about any email threats as Avanan catches everything."
"Go for it! I think it's an excellent product with great technical support."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
 

Cons

"They should come up with a mobile application so that it can be more flexible."
"Integration with various SaaS offerings, who are leading in the SaaS market. Examples include: SNOW (ServiceNow), Salesforce.com"
"The system could be designed to give corporate emails first priority due to demands."
"There are some things that they can't remediate. The honest thing is nobody can right now because of the nature of how some of the secure email platforms work."
"The cost is higher for SMEs, however, the pricing and billing criteria can be lessened to accommodate more willing customers."
"Email querying is not efficient throughout."
"The system response in a slow computing device affects performance when sending and receiving emails."
"It should reduce the amount of time needed for thorough scanning."
"I am not satisfied with Clearswift because of the lack of customer support."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The pricing of Avanan is reasonable."
"Avanan’s price is comparable to Barracuda."
"The product is not the cheapest in the market."
"Good pricing arrangement as an SaaS offering."
