## OpenText Core Email Threat Protection Reviews
  ### 1. Doesn't Catch Obvious Phishing Emails, Customer Support Is Awful

**Rating:** 0.0/5.0 stars

**Reviewed by:** Verified User in Civil Engineering | Mid-Market (51-1000 emp.)

**Reviewed Date:** September 30, 2025

**What do you like best about OpenText Core Email Threat Protection?**

It's cheap. One can also block a domain.

**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.

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

It's supposed to be solving spam and phishing emails. At this point, I'm not sure it is benefiting me.

  ### 2. Reduce Inbox Clutter

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Government Administration | Mid-Market (51-1000 emp.)

**Reviewed Date:** March 01, 2024

**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.

**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.

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

AppRiver Email Threat Prevention greatly reduces the amount of spam delivered to our inboxes.  It allows the end users to view held messages safely and release them to their inbox if needed.  Users can also request whitelist entries or manage their own, personal whitelists if permitted to do so.  From an administrator's perspective, you are given the ability to tweak the filtering system significantly to meet your needs.

  ### 3. Never have to worry about SPAM

**Rating:** 5.0/5.0 stars

**Reviewed by:** Scott H. | Network Administrator, Mental Health Care, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 20, 2023

**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.

**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.

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

The weakest link into a network is the end user email and AppRiver Email Threat Protection is a great shield. You can never catch everything but in the 7 years I've been here I have only had a few real threats slip past the filters and I was able to immediately adjust the filters to stop future threats.

  ### 4. Perfect

**Rating:** 5.0/5.0 stars

**Reviewed by:** steven L. | IT Consultant, Information Technology and Services, Mid-Market (51-1000 emp.)

**Reviewed Date:** March 22, 2023

**What do you like best about OpenText Core Email Threat Protection?**

I like Appriver because It has a lot of features that the end user cant touch

**What do you dislike about OpenText Core Email Threat Protection?**

The only thing will be making it a little more user friendly

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

Too much spam/junk mail getting to the end users.

  ### 5. Appriver's filters do a decent job of blocking threats but need to improve

**Rating:** 3.5/5.0 stars

**Reviewed by:** Philip D. | Director Of Information Technology, Mid-Market (51-1000 emp.)

**Reviewed Date:** August 24, 2021

**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.

**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.

**Recommendations to others considering OpenText Core Email Threat Protection:**

Configure it so that your users get quarantined messages reports very often so that important messages that were quarantined don't get missed.

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

Spam and malicious email is an enormous problem and Appriver helps us manage it.  It saves time for the IT dept. by automatically filtering messages and removing them and alerts us when we need to intervene.  The portal is easy to use and support has been great.

  ### 6. Full-featured but a bear to administer

**Rating:** 3.0/5.0 stars

**Reviewed by:** Verified User in Investment Management | Small-Business (50 or fewer emp.)

**Reviewed Date:** November 03, 2021

**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.

**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.

**Recommendations to others considering OpenText Core Email Threat Protection:**

I recommend that anyone who needs email threat protection consider alternatives to AppRiver. No matter who good the protection might prove to be managing this service is difficult.

**What problems is OpenText Core Email Threat Protection solving and how is that benefiting you?**

AppRiver is our spam, malware and phishing protection. Considering the deluge of threats arriving via email every company requires an email security gateway, and for us that's AppRiver.
