"Doesn't Catch Obvious Phishing Emails, Customer Support Is Awful"
0/5
What do you like best about OpenText Core Email Threat Protection?

It's cheap. One can also block a domain. Review collected by and hosted on G2.com.

What do you dislike about OpenText Core Email Threat Protection?

It doesn't catch emails that are obviously phishing attempts. Some of the subjects of emails AppRiver hasn't caught:

Alert: Update Your Microsoft 365 Password Before Expiry[random character string]

[Company Name] HR: Employee Guidelines Ref ID: [Random characters]

[Company Name] sent 3rd Quater Performance-Based Review and Annual Raise Ref :[random character string]

Payroll Adjustment Q2 Performance Review and Employment Compensation Ref [random characters] [Date]

The filtering functionality is very limited, so even if there's an obvious pattern, one can't create any rule to prevent it. Responses are slow and unhelpful. It actually seems like it's been getting worse lately, though it's hard to tell. Review collected by and hosted on G2.com.

4/5
What do you like best about OpenText Core Email Threat Protection?

On average, AppRive Email Threat Protection filters out around 25% of our incoming email as spam or malware. Users are notified daily of any messages that have been blocked and given the option to view and release blocked messages that are legit. In addition, they can also request global whitelist entries or, if given permission, manage their own, personal whitelists. Our end-users find using this service easy to understand and use. When needed, the customer support is always easy to work with and quick to answer questions. Review collected by and hosted on G2.com.

What do you dislike about OpenText Core Email Threat Protection?

By default, only the past 7 days of filtered messages are maintained. We were able to request 14-day retention but that is the maximum offered. It would be nice to have a longer retention options. Review collected by and hosted on G2.com.

"Never have to worry about SPAM"
5/5
What do you like best about OpenText Core Email Threat Protection?

I ahve been with AppRiver's Email Threat Protection since I came on board with El Hogar. I have not once had to lose sleep over spam. There are a few that get through their filters if you don't lock them down but 90% of SPAm is weeded out. The Customer Support is excelent and I typically get right through to an agent when help is needed. I really appreciate that. Review collected by and hosted on G2.com.

What do you dislike about OpenText Core Email Threat Protection?

When first configuring the settings you can accidently catch too much and you have to spend a few days tweeking it to meet your needs. Once you do that, it is set it and forget it. Review collected by and hosted on G2.com.

"Appriver's filters do a decent job of blocking threats but need to improve"
3.5/5
What do you like best about OpenText Core Email Threat Protection?

Appriver helps keep our organization secure by blocking thousands of malicious emails every day. Our users receive frequent reports on quarantined items so that they can request the admin to release any messages they need. This keeps us safe and makes sure we don't miss vital communication that may have been blocked. Better safe than sorry. Review collected by and hosted on G2.com.

What do you dislike about OpenText Core Email Threat Protection?

The filters can miss dangerous emails from time to time and when these messages get through you cannot recall them from the mailboxes without paying for extra features from Appriver. I think this service should be included in the basic threat protection package because it is vital for security. Review collected by and hosted on G2.com.

"Full-featured but a bear to administer"
3/5
What do you like best about OpenText Core Email Threat Protection?

AppRiver appears to have all of the features I expect from an email security gateway. Review collected by and hosted on G2.com.

What do you dislike about OpenText Core Email Threat Protection?

The administration web interface is terrible, possibly the worst I've seen in this market segment. Navigation is fragmented, clumsy and without any flow. Review collected by and hosted on G2.com.
