We added PhishProtection to our environment to specifically help with phishing attempts via emailed links. We vetted several solutions and the cost of this product added features we needed while we were able to retain existing systems that had features we needed that other solutions don't provide. DuoCircle's support is accessible and great. They will invest time where needed to troubleshoot issues. New features that could be helpful are considered, and implemented where possible, to make the system work better for our needs. Review collected by and hosted on G2.com.

This product didn't meet all of our needs for a Secure Email Gateway, but the price point made it a good add-on to our mail flow to have additional features and security. Review collected by and hosted on G2.com.

Advance level of security with easy UI and workflows built in the solution, that even a novice can understand it. Must add, with URL security, it adds value to the protection services. Review collected by and hosted on G2.com.

We're using the service for INCOMING mails only and our mail domain service is running on some other platform. One might face critical problems, if they mail server domain on a different service provider, who's not expert in their fields. You'll find yourself in middle of lots of to-and-fro with no solution, if the root cause is not identified easily. Review collected by and hosted on G2.com.

Phish protection provides a seamless integration for our users, except for the spinning globes, nobody really notices it is there. Review collected by and hosted on G2.com.

Sometimes it takes more than a few seconds to check the link.

There is also a bit of a learning curve for the site, sometimes have to file requests to let the developers know that a particular link is indeed safe.

If there is any way to speed up the link checking, perhaps with a faster data store, in the back-end, so that our users really don't notice it is even there.

If it gets to this stage, then we can even remove the spinning globes, and the integration will be completely seamless.

You may want to consider folding in the cost of the service with the standard mail gateway professional.

There is no reason any site should not be using something like this.

A little more automation around the required CNAME and other DNS requirements would be a nice touch. Review collected by and hosted on G2.com.

What we love the most is the ease of deployment. You simply point your MX records to DuoCircle and that's it, filtering begins immediately. Also, all hyperlinks that arrive in an e-mail to the end users are changed to make sure users are protected from malicious links. If the user clicks the link; DuoCircle scans that link for potential infection and informs the user to go no further "OR" they can click through the link at their own risk. In the Admin Portal, you can disable the Click-Through option and deny end users that option if needed.

The Admin portal is very straightforward. You can Whitelist domains or e-mails, or Blacklist domains and e-mails that you wish to have filtered out. So far, we have noticed around 99% reduction in the amount of spam that was hitting our 365 accounts. DuoCircle stays on top of newly created websites and spam e-mails and adds them to their database for scanning.

Additional domains can be added to the portal that are on the same 365 server as well. This made it a slam dunk for us to bring all of the domains under one spam filtering service. Review collected by and hosted on G2.com.

To be honest, there really isn't much to dislike about the service provided from DuoCircle, so far, very happy with the service and the price cannot be beat. We researched other vendors in this category and all of them came up with much higher pricing. Review collected by and hosted on G2.com.

All "phishy" links in an email are automatically converted to route the traffic through a security process before you are connected to the destination site. Review collected by and hosted on G2.com.

The only minor issue is the following: When I determine, after visiting a (safe!) site by clicking the converted link, that I want to reuse this link, say in a social media post or in a document to be published, there is no easy way to "re-convert" the safe link into its original URL. It would be nice to have an easy option for such reinstatement of the original link. Ideally, through a command triggered by option-clicking on the link or, for example, by a simple web-based tool where I paste the converted link and get it translated back.

Duo has solved our unique issues, we brought them an unusual issue and the owner took personal time to solve it with us. Review collected by and hosted on G2.com.

Nothing, the service is high quality. The on-demand support and the appointment based support has been great. Review collected by and hosted on G2.com.

Knowing that end-users are shielded from the bulk of fake emails makes my life a lot easier! I particularly like the real-time link checking feature. Review collected by and hosted on G2.com.

Occasionally one-time verification links can fail due to re-writing but usually this can be overcome by sending a second time. Review collected by and hosted on G2.com.

I do enjoy its simplicity and the pricing. For smaller companies this is a bargain for everything you get. But by far the one thing that did bring me here was its link scanner. I did not see this option on other providers. I was always nervous about emails that had links. Would my Firewall block it? What if they are looking at it at home? With the link scanner I am always sure that the link goes through a scan regardless if they are at work or not. It just adds to the protection. This issue just recently came up with the dreaded Invoice email. I clicked on the link, got scanned, and it was blocked. A nice test. Review collected by and hosted on G2.com.

Some times the Link Scanner takes a long time. Not sure why. Seems to only happen at another building that is connected through a VPN. Have not experienced it at our Main location. The only other issue would be a feature add on I would like. I would like to restrict emails from certain countries. We have no reason to expect emails from Russia or China and I would like to block those. Review collected by and hosted on G2.com.

The Phish Protection by DuoCircle bring a sense of comfort to my business. We all know users are unpredictable. This service stops the malicious messages before the user can do anything. As a personal example, I received an email, that I was expecting, from someone I knew. It had a subject that seemed normal. I did everything I could to open the email, but the Phish Protection stopped me. I finally gave up and called the vendor, only to find out that they had been attacked by ransomware. I am so thankful that this product protected us. We use it on every domain that we have. I recommend to everyone regardless of their email service. Review collected by and hosted on G2.com.

The interface can be slow. The syntax to fully understand how to use the queries can be hit or miss. I usually have to guess and try various searches before I can find something obscure. I do like the full logging of every message that hits the email server, so that, when troubleshooting I know exactly where communication breaks down. Review collected by and hosted on G2.com.

Our users no longer fall for phishing emails or click links they shouldn't. I have full control over monitoring phishing emails and get alerts when a suspicious email is a click. Review collected by and hosted on G2.com.

Nothing specific - it's a really great product. Review collected by and hosted on G2.com.
