Robert Melendez - PeerSpot reviewer
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.
PC
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

"Spam protection is the most valuable feature."
"It can detect corrupted files and filters out documents with viruses."
"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."
"This technology is one of Check Point's acquisitions, and it is currently a powerful tool that provides all the protection that is not found in other tools."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"Easy to use for non-technical users."
"When we don't understand some functionalities, the customer support staff responds fast to our calls and provides immediate action."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"It is very difficult to find the required documentation."
"Being cloud first and because we are in the movie business, we use a lot of Macintoshes. So, there is absolutely no reason for us to have Active Directory whatsoever. However, if you are using Office 365, you must have Active Directory in order to reset passwords. Even though we have a single sign-on provider, we must have Azure Active Directory for Office 365, which is really stupid. As a cloud application, you would think that I don't need Active Directory, which I don't need for anything else except Office 365. We have one server inside that space to help us manage Active Directory just for Office 365. This is a very sore point, but it is what it is."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Avanan doesn't cover certain tool segments."
"There are times when we have false positives."
"It should reduce the amount of time needed for thorough scanning."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"The pricing of Avanan is reasonable."
"The product is not the cheapest in the market."
"Avanan’s price is comparable to Barracuda."
"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."
"Good pricing arrangement as an SaaS offering."
