Enterprise (\> 1000 emp.) 3/10/2020 "PhishProtection with DuoCircle is a great addition" 4.5/5 What do you like best about Phish Protection by DuoCircle? 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. What do you dislike about Phish Protection by DuoCircle? 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. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? Beyond assistance with protection for emailed links, we have found other features that meet evolving needs. During inquiry on a way to manage a high visibility issue, we learned that DuoCircle was testing and implementing a new feature that met our needs for alerting email recipients to fraudulent emails that appear to come from Company Officers. We were able to be become an early adopter to quickly tag these emails. Review collected by and hosted on G2.com. Show More Current UserValidated ReviewerIncentivizedSource: Seller invite AK Amit K. Head - BPR and Sales Automation Small-Business (50 or fewer emp.) 3/7/2020 "DuoCircle's Email Gateway and Advance Threat Defense is an amazing solution" 5/5 What do you like best about Phish Protection by DuoCircle? 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. What do you dislike about Phish Protection by DuoCircle? 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. Recommendations to others considering Phish Protection by DuoCircle: DuoCircle Phish Protection is an amazing solution with lowest cost possible, I would seriously recommend to test it. After the test, I'm 100% sure, you'll love it. Review collected by and hosted on G2.com. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? Email security including URL protection (within mails) We've been able to keep control on the spamming and email based attacks through the solution. Add to it, the link protection also help us keep our systems and data safe if the used link is illegitimate/ infected/ etc. 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. What do you dislike about Phish Protection by DuoCircle? 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 problems is Phish Protection by DuoCircle solving and how is that benefiting you? We use phish protection to secure all of our incoming E-Mails. Our users don't even really notice anything has changed, except for the spinning globe, and a 3 second delay when a link is pressed. It would be ideal if there was a button right on the page that allowed a link to not only be followed, but to be added to the white list. This would obviate the need for an admin to go online and do it manually. 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. What do you dislike about Phish Protection by DuoCircle? 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. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? Current problems we were facing that DuoCircle solved for us is the hyperlinks sent in e-mails to which end users will typically click on automatically without thinking, and get phished. DuoCircle prevents this from happening by overwriting the URL's. 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. What do you dislike about Phish Protection by DuoCircle? 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.

What problems is Phish Protection by DuoCircle solving and how is that benefiting you? When you're not sure whether a link is legit, Phish Protection takes the guesswork out of your process.

Provides additional piece of mind." 5/5 What do you like best about Phish Protection by DuoCircle? 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. What do you dislike about Phish Protection by DuoCircle? 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. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? End-users simply aren't always able to determine if an email is a Phishing attempt or not - PhishProtect is a great way of taking the decision away from them. Also, rewriting of links allows real-time checks to be performed and this is also very helpful in protecting the orgnaisation. Review collected by and hosted on G2.com.

Microsoft Engineer Mid-Market (51-1000 emp.) 3/12/2020 "Duo Circle Phish Protection" 3.5/5 What do you like best about Phish Protection by DuoCircle? 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. What do you dislike about Phish Protection by DuoCircle? 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. Recommendations to others considering Phish Protection by DuoCircle: I have yet to see anything like this product. The ability to re-write the links inside of emails to use the scanner is unlike any product I have used in the past. If you are only using a single Domain for email then the price is really hard to beat. I plan on moving a few other clients to this. Review collected by and hosted on G2.com. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? As stated above, sometimes takes a long time to scan. But having it does make me feel a little better and the few times it does take a while I feel its worth having. This only happens at one office and its not very often.

Owner Mid-Market (51-1000 emp.) 3/9/2020 "Excellent Product, excellent interface, excellent support, wonderful peace of mind!" 5/5 What do you like best about Phish Protection by DuoCircle? 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. What do you dislike about Phish Protection by DuoCircle? 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. Recommendations to others considering Phish Protection by DuoCircle: Give it a try. You will not regret it. Review collected by and hosted on G2.com. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? Like everyone else, we are under constant bombardment from UCE. Filters are good but not perfect. The URL screening has been much more reliable and predictable. It offers a higher degree of assurance to the end users as well. Only a few times have we had to address false positives or deal with the URL string being too long for a web browser. Review collected by and hosted on G2.com.

What problems is Phish Protection by DuoCircle solving and how is that benefiting you? We were receiving numerous phishing emails and fraudulent emails including attempting to deliver ransomware.
